What issues should be paid attention to when purchasing a newly purchased UPS

/0 Comments/in /by

When buying a new UPS power supply, in order to ensure that the UPS power supply host can work normally, what problems should be paid attention to during use?

        UPS power supply attention

1. The newly purchased UPS power supply should be charged before use.

During the storage of the UPS power supply, the battery continues to self-discharge and most of its capacity is consumed. If the power is not replenished in time, it will not only affect the normal use, but also shorten the battery life. The method of charging the battery is to connect the batteries in series and charge according to the specific method provided in the battery instruction manual. Usually, constant voltage charging is used. The control voltage of each battery is 2.30~2.35V, and the initial current limit should not exceed 0.25C5A (C5 can calculate the specific value through the rated capacity of the battery) to avoid charging the battery. The charging current is enough for 3 hours and can be put into use. Charging time is 12~24h.

2. UPS power supply should avoid frequent power-on and shutdown

The newly purchased UPS power supply is best turned on for a long time.

3. Even if the battery returns to normal, the UPS power should be restored immediately after use.

In a 25 ° C environment, a fully discharged battery takes 18 to 24 hours. If the energy is not discharged, it can be terminated according to the continuous current.

4. If the user configures the long delay battery pack, the external charger should have both constant voltage and constant current functions.

Chargers with constant voltage should not be used to avoid affecting battery life.

5. Check the floating voltage every month when using UPS power

When the floating voltage of a single battery is lower than 2.20V, the entire battery should be charged equally. The method is: in the environment of 25 ± 5 ° C, the initial current limit should not exceed 0.25 C5A, the constant voltage is 2.35 to 2.40 V, and the charging time is 24 to 48 hours.

Battery fire safety instructions

/0 Comments/in /by

When we use electronic products, we can’t do without battery power. Battery safety is also a problem that cannot be ignored, so we need to understand the safety of battery fire protection.

1. The room should be kept clean and there should be no flammable materials to prevent contact with sulfuric acid.

2. The battery pack should be installed in a dedicated room. Frosted glass or white plain glass should be applied to the sunny window. The entire room is coated with acid-proof paint, and the entrance of the battery room should be equipped with an explosion-proof door bucket to avoid direct collusion with other housekeeping staff. The battery unit is located on the board.

3. The battery and frame are separated from the floor application gasket. However, battery trays below 48V may not be equipped with gaskets. The distance between the battery and the wall should not be less than 150mm. When arranged on both sides, the width of the passage between the battery packs shall not be less than 1 m; the arrangement on one side shall not be less than 0.8 m.

4. Large acid storage rooms should be equipped with a special acid conditioning chamber for storing sulfuric acid and preparing electrolytes. The battery compartment should be provided with ventilation. All electricity discharged from hydrogen, oxygen and sulphuric acid gases discharged during charging to the two battery compartments shall comply with explosion-proof requirements and the lighting circuit shall be made of acid-resistant wires.

Pay attention to the small details in life and learn more about safety.

What are the safety implications of lithium-ion batteries

/0 Comments/in /by

In general, lithium-ion batteries have safety problems that appear to be burning or even exploding. The root cause of these problems lies in the thermal runaway inside the battery. In addition, some external factors such as overcharge, fire, extrusion, puncture, and short circuit. Other issues can also lead to security issues. Lithium-ion batteries will generate heat during charging and discharging. If the generated heat exceeds the heat dissipation capacity of the battery, the lithium-ion battery will overheat, and the battery material will decompose the SEI film, decompose the electrolyte, decompose the positive electrode, and the negative electrode. A destructive side reaction such as a reaction of an electrolytic solution and a reaction between a negative electrode and a binder.

1 Safety hazard of cathode material

When the lithium ion battery is used improperly, the internal temperature of the battery is increased, so that the decomposition of the active material and the oxidation of the electrolyte occur in the positive electrode material. At the same time, these two reactions can generate a large amount of heat, causing a further increase in battery temperature. Different delithiation states have a great influence on the lattice transition of the active material, the decomposition temperature and the thermal stability of the battery.

2 The safety hazard of the anode material

The anode material used in the early stage is metallic lithium. The assembled battery is prone to lithium dendrite after repeated charge and discharge, and then pierces the diaphragm, causing short circuit, liquid leakage and even explosion of the battery. The lithium intercalation compound can effectively avoid the generation of lithium dendrites and greatly improve the safety of the lithium ion battery. As the temperature increases, the carbon negative electrode in the lithium intercalation state first undergoes an exothermic reaction with the electrolyte. Under the same charge and discharge conditions, the heat release rate of the electrolyte reacted with lithium-incorporated artificial graphite is much higher than that of the intercalated carbon microspheres, carbon fibers, coke, etc. with lithium intercalation.

3 Safety risks of diaphragm and electrolyte

The electrolyte of the lithium ion battery is a mixed solution of a lithium salt and an organic solvent, wherein the commercial lithium salt is lithium hexafluorophosphate, the material is susceptible to thermal decomposition at a high temperature, and is subjected to a thermochemical reaction with a trace amount of water and an organic solvent to reduce Thermal stability of the electrolyte. The organic solvent of the electrolyte is carbonate. These solvents have a low boiling point and a low flash point, and are easily reacted with the lithium salt to release PF5 at a high temperature, and are easily oxidized.

4 Safety hazards in the manufacturing process

Lithium-ion batteries in the manufacturing process, electrode manufacturing, battery assembly and other processes will have an impact on the safety of the battery. Such as the positive and negative mixture, coating, rolling, cutting or die cutting, assembly, filling of the amount of electrolyte, sealing, chemical and other processes of quality control, all affect the performance and safety of the battery. The uniformity of the slurry determines the uniformity of the distribution of the active material on the electrode, thereby affecting the safety of the battery. The fineness of the slurry is too large. When the battery is charged and discharged, there will be a large change in the expansion and contraction of the negative electrode material, and precipitation of metallic lithium may occur; if the fineness of the slurry is too small, the internal resistance of the battery may be too large. When the coating heating temperature is too low or the drying time is insufficient, the solvent remains, and the binder is partially dissolved, causing some active materials to be easily peeled off; if the temperature is too high, the binder may be charred, and the active material may fall off and cause internal short circuit of the battery.

5 Safety hazards during battery use

Lithium-ion batteries should be used to minimize over-charging or over-discharging during use. Especially for batteries with high monomer capacity, thermal disturbances may cause a series of exothermic side reactions, leading to safety problems.

India’s Q3 solar cell and module exports increased by 223%, imports increased by 38%

/0 Comments/in /by

According to the latest data from the Ministry of Commerce, India imported $602 million of solar modules and batteries in the third quarter of 2018, an increase of about 38% compared to $4.3663 billion in the second quarter, despite imports compared to the same period last year. It has dropped by 17%.

In the third quarter of 2018, India exported $562.3 million in solar cells and modules, an increase of 223% compared to $197.4 million in the second quarter of 2018.

360截图17571113104152106.jpg

Mercom believes that in the past few months, India’s PV installations have been slow due to uncertainties in safeguarding tariffs and exemptions, and the issue of excise tax remains unresolved. Even the import of solar modules from Vietnam and Thailand, which are not on the list of safeguards, requires the issuance of temporary bonds and statements, which also seem to affect trade activities.

360截图17571113104152106.jpg

China remains India’s largest supplier of solar modules and batteries. In the third quarter of 2018, solar cells and components imported from Chinese companies accounted for nearly 84.5%, a slight increase from 75.9% in the previous quarter.

The batteries and components from Singapore accounted for 6.9% of India’s total imports of solar cells and components in the third quarter of 2018, totaling $0.413 billion. Singapore has become India’s second largest solar supplier. In the three months from July to September 2018, Singapore’s market share more than doubled.

Taiwan surpassed Malaysia, Canada, Thailand, Vietnam and Hong Kong to become India’s third largest solar module and battery supply area, accounting for 3.8% of the market.

In the third quarter of 2018, solar modules from Malaysia accounted for 1.3% of India’s total solar imports, Canada and Thailand each accounted for 0.7%, Vietnam with 0.6% and Hong Kong with 0.4%.

In the third quarter of 2018, the United States accounted for 58% of all solar modules and batteries exported by India. This is down from 63% in the previous quarter. Denmark, Australia, Poland, the Netherlands and Belgium are other major countries that purchase solar cells and components made in India.

Protable Solar Generator power supply can not block the cause of lightning current damage

/0 Comments/in /by

Direct lightning strikes, inductive lightning and lightning electromagnetic pulses can damage the Protable Solar Generatior power supply. These lightning energy is huge, which also causes some Protable Solar Generatior power sources to stop the fate of being damaged. There are several main reasons:

1. There are two types of UPS with lightning protection installed inside

①Protable Solar Generatior is equipped with unqualified lightning protection device

This manufacturer only symbolically installs a low-power metal zinc oxide varistor MOV to save costs, which only protects small inductive lightning.

②equipped with standard lightning protection device

Some imported UPS and UPS produced by the famous Protable Solar Generatior factory in China comply with the international IEC801-5 standard (suppressing the lightning surge voltage and current surge at the input end of the absorption power supply, the inrush current is 20kA, the pulse voltage is 6kV, and the waveform is 8 / 20μs). These types of Protable Solar Generatior can protect the UPS itself intact and protect other subsequent power supplies and equipment from lightning damage.

Long-term monitoring statistics show that the overvoltage of the general low-voltage overhead line generated by DC lightning strikes can reach 100kV, and the telecommunication line can reach 40~60kV. On unshielded overhead lines, the maximum amplitude of the induced lightning overvoltage is 20kV, and the unshielded underground cable can reach 10kV. It can be seen that even a UPS equipped with a standard lightning protection device is also equipped with an effective high-energy lightning protection device at the front end of its power line (the power distribution room, room, cabinet and box, and the UPS is also damaged by lightning). .

2.Intelligent Protable Solar Generatior, signal interface or remote communication line interface is equipped with missing materials

Some are not equipped with surge circuits, and some are only equipped with low-power surge suppression circuits, which cannot prevent inductive lightning strikes, so their signal or communication line interfaces also become the main channel for lightning wave intrusion.

3.Protable Solar Generatior is installed at the front end of important equipment

When a lightning strikes a low-voltage power line or generates an induced lightning strike on the cable, the overcurrent and overvoltage on the power line pass through the power distribution system, first affecting the UPS. The UPS voltage regulation range is generally 160~260V, three-phase, 320V. ~460V between. It is impossible to prevent the overvoltage range of the 10-20kV lightning shock wave in an instant, so when the lightning strike arrives, it is the first to be hit by the lightning current.

In summary, the Protable Solar Generatiorwithout lightning protection device can be said to have no lightning protection function, and can only be used as a power supply for urban power grid over-voltage or small stray current purification and protection. When a lightning strike occurs, it is first hit; the UPS with lightning protection device cannot fully protect itself, protect the power of other equipment from lightning strikes; direct attack of overhead power lines and signal lines, lightning overvoltage and induced lightning overvoltage are smart protable solar generatior damage. The main reason. Therefore, it is necessary to strengthen the lightning protection measures of protable solar generatior power supply, which is of great significance.

7 protection functions of UPS power supply

/in /by

The Portable Splar Generator power supply is an uninterruptible power supply with a constant voltage constant frequency, including an energy storage device and an inverter as main components.

In addition to uninterrupted power supply, it has 7 major protection functions:

1.Surge protection

Typically, UPS power systems use a tip-discharge design to absorb surges to avoid the effects of surges and the life and longevity of the equipment.

2. Voltage regulation

The supply voltage is easily affected by the distance and quality of the transmission line. The voltage of the user close to the substation is higher and the voltage of the user away from the substation is lower. If the voltage is too high or too low, it will affect the quality and service life of the user equipment. If it is severe, it will damage the equipment and cause significant damage to the user. The use of the UPS power system provides a stable voltage supply to the user equipment, ensuring proper operation of the equipment and extending its service life.

3. High and low voltage protection

When the supply voltage is high and low, the regulator (UP) in the UP supply maintains the supply voltage within a safe range that can be used to ensure proper operation of the device. When the high and low voltages exceed the available range, the UPS power system will start battery power to ensure continuous operation of the equipment.

4. Harmonic distortion protection

When power is transmitted to the consumer through the transmission and distribution lines, the voltage waveform is distorted and the fundamental current changes to produce harmonics. Harmonics can affect the use of equipment. Through the UPS power supply, it can provide stable and high-quality power for the equipment, effectively improving the operating efficiency and service life of the equipment.

5. Instant protection

In power supplies, voltage surges and voltage dips or transient voltage drops sometimes occur. These issues can affect the accuracy of the device. In severe cases, precision equipment can be damaged and the user suffers losses. The UPS system provides a stable voltage to protect the device.

6. Power failure protection

When the mains power supply suddenly loses power, the UPS power system converts the UPS battery DC power into AC power and continues to supply power to the load to avoid inconvenience and loss caused by power outage.

7. Stable frequency effect

The frequency is the time period during which the power supply changes every second, and 50 Hz is 50 cycles per second. When the utility generator is running, a sudden change in the power consumption of the user terminal causes a change in the rotational speed to make the converted power frequency uncertain. The UPS power conversion power supply provides a stable frequency to ensure proper operation of the instrument and equipment.

How much electricity can a photovoltaic panel emit in a year

/0 Comments/in /by

China has a vast territory and abundant solar energy resources. In 2000, China’s photovoltaic installations only had a 20,000-kilowatt area, which was less than 1/15 of that of Japan, and it has stagnated for many years. In July 2011, China issued the Notice of the National Development and Reform Commission on Improving the On-grid Price Policy for Solar Photovoltaic Power Generation. Encouraged by the policy, in the hard work of the whole industry, in 2015, China became the world’s largest PV application market. In 2017, the country’s new PV installed capacity was 51.06 million kilowatts, with a cumulative installed capacity of more than 1.3 trillion kilowatts.

After talking about the macroscopic events of the photovoltaic industry, return to the microscopic photovoltaic panels. If someone suddenly asks you, how many powers can a photovoltaic panel emit in a year? Probably a lot of people will blaspheme, yeah, how much?

This involves two determinants of photovoltaic power generation:

1. Photovoltaic panel power generation

2. Installation area of ​​photovoltaic panels

In the same region, the higher the power generation of photovoltaic panels, the shorter the time spent on generating 1 kWh, and the higher the power generation in one day.

The 1 degree electricity we commonly talk about is converted to the term 1 kWh (1 kWh), which is 1000 watt hours (1000 Wh). That is, 1 degree of electricity = 1 kWh (1 kWh) = 1000 watt hours (1000 Wh).

According to a well-known brand battery board LR6-60-285M, its nominal power is 285W. Then, it takes 1000Wh ÷ 285W ≈ 3.5H to send 1 degree of electricity.

It takes 3.5 hours to send 1 degree of electricity, so is the annual power generation not 365×24÷3.5? If you do this, you have to laugh at your big teeth.

Why? Photovoltaic panels, photovoltaic panels, with sunlight to generate electricity. Therefore, it will not be able to send electricity at night. In the same way, the wind and the smog, the rain and snow, and almost no electricity. This leads to another term for photovoltaic power generation – the equivalent hours of use per year.

In 2013, the National Development and Reform Commission issued the “Notice on Playing the Role of Price Leverage to Promote the Healthy Development of the Photovoltaic Industry”. The notice is clear, according to the local solar energy resources and construction costs, the country is divided into three types of solar energy resources.

The solar resource area is divided according to the annual equivalent utilization hours. The annual equivalent utilization hours are more than 1600 hours for the Class I resource area, and the annual equivalent utilization hours are between the 1400-1600 hours for the Class II resource area. The utility hours are between Class III and 1400-1400 hours.

According to the classified I, II, and III regions of the country, the reference to the equivalent hours of use in the year, the longer the duration, indicating that the larger the solar energy resources available locally, the corresponding value will increase accordingly.

This means that photovoltaic power generation is closely related to the installation area. Different resource areas, the same type of photovoltaic panels, will also generate different amounts of electricity. In some places, there is plenty of light and it is inherently dominant.

It can be seen from the comparison table that the Hebei area belongs to the Class II and Class III areas, that is to say, the annual equivalent utilization hours are 1200-1600, and the average value of 1400 hours is calculated in the middle. The annual power generation is 1400 ÷ 3.5 = 400 (degrees).

Now, we can answer the question – how many kilowatts a photovoltaic panel can emit in a year – 400 degrees (theoretical).

Why is it a theoretical value? This is because, in addition to the photovoltaic power generation capacity and installation area (annual equivalent utilization hours), photovoltaic power generation is subject to external factors such as installation angle and orientation, local climate, connection line material, and surface occlusion. Things and so on.

Installation of photovoltaic panels requires the installation of angles and orientations in order to maximize the acceptance of the photovoltaic panels. If it is installed indiscriminately, people have angles, you are lying flat; people sitting north facing south, you are sitting south to the north, and deviate from science, but it does not affect the amount of electricity generated!

For example, there are extreme weathers that have not been seen for decades in the region. Rainfall, snowfall, smog for a long time, sandstorms, etc., even the sun can’t see, no matter how good the photovoltaic panels can’t be!

If you use a line such as a poor quality cable, the power is sneaked out, and the hair is no longer useful, and it is prone to accidents. This shows the importance of the material.

The obstructions of the photovoltaic panels should be cleaned from time to time. For example, there are big trees near the photovoltaic panels, or tall houses. The total illumination is not much, how to fully generate electricity. This is the problem of site selection. Or, the local wind and sand is large, only the photovoltaic panels are installed, but they are not carefully maintained. The panels are dusty and cannot fully generate electricity.

All of the above are factors that affect photovoltaic power generation. Therefore, the photovoltaic power generation we have just calculated is 400 degrees a year is the theoretical value. However, even the theoretical value of 400 degrees is enough. Think about the life cycle of a photovoltaic panel for about 25 years, 400 × 25 = 10000 kWh, which is several times the profit.
