UPS power storage battery failure causes and daily maintenance suggestions. UPS is widely used is a maintenance-free sealed lead-acid battery. The UPS lead-acid battery will have some damage and fail during usual use, and the battery failure is due to battery consistency.

The consistency of the battery is the soul of the battery, overwhelming the factor! UPS power storage battery failure causes UPS power supply lead-acid battery failure may have a variety of reasons, such as vulcanization, loss of water, thermal out of control, active material falling, polar plate softening, etc. Next, Xiaobian said one by one. 1.

The process of vulcanization UPS power storage battery charge is the process of electrochemical reactions. When discharged, lead the lead in sulfate, and the lead-reduction of sulfate is lower as the lead. This electrochemical reaction process is normal in the normal conditions, but the lead of sulfate is an easy crystallization, and when the electrolytic solution of the electrolytic solution in the battery is too high or when the idle time is too long, it will "hug" The group is formed into small crystals.

These small crystals are further attracted by lead, which is like the same to form a large inert crystallization like the snowball, which destroys the original reversible circulation, leading to the lead part of the sulfate. When the crystal sulfate is charged, it cannot be restored to the lead, but also adsorbed on the grid plate, resulting in a decrease in the working area of ​​the grid, and the lead-acid battery is released, and the lead-acid battery capacity is lowered. This is called vulcanization.

That is, the aging. Vulcanization also causes "complications" such as short-circuit, active substance relaxation, grid deformation and other "complications". As long as it is a UPS power battery, it will vulcanize during use, but the lead-acid battery in other fields has a longer life than the lead-acid battery used in the electric bicycle, because the lead-acid battery of the electric vehicle has one More easily vulcanized working environment.

2. Powder-free group of 36 volts has 3 monomer UPS power cells, each monomer battery has 6 monographs, each mononener has more than 15 positive and negative edge, and a set of batteries have the least 270 solder joints, if a few-third of the solder welding will result in a group of unqualified groups per 4 sets of batteries, and the lead calcium plate is very easy to cause the precautions for calcium, so the battery manufacturer generally uses low bismuth alloy. Board, while the low-ruthenium alloy is lowered, the amount of gas supply is larger, and the loss of water is more serious.

3. The thermal out-of-control charging itself is the exothermic reaction, and the thermal design of the general lead-acid battery can be controlled. After the UPS power supply lead-acid battery, the oxygen is composite water in the negative electrode plate, and the heat generation is far greater than the fever at the time of charging.

Sealed lead-acid batteries wish the negative electrode plate have good oxygen circulation capabilities, but the oxygen circulation will occur. Therefore, oxygen circulation is a double-edged sword, the benefit is to reduce water loss, the disadvantage is the battery. 4.

Active material falls off, the active ingredient of the polar plate active substance of the polar panel softened UPS power storage battery is the lead, oxidative lead α-PbO2 and β-PbO2, wherein the α-PBO2 physical characteristics are hard, and the capacity is relatively small. Porous shape Atthe a plate, for enlargeing the plate area and the support plate; the β-PbO2 is formed over the skeleton composed of α-PbO2, and the charge power is much larger than the α-PbO2, and the lead-discharge discharge is formed, and the lead, charging. Lead of sulfate is reduced to lead, but the lead in sulfate can only be generated in a strong acid environment, and the active material is falling off.

5. Short-circuit UPS battery short circuit refers to the positive and negative blocks of the lead battery. The microcathy is backward after the micro-short road, and a single short circuit will appear when it is serious.

The active material expands on the plates will also cause positive and negative plates. UPS Power Supply Battery Daily Maintenance Suggestions 1. Maintaining a suitable ambient temperature, affecting the factors that affect the life of the UPS power battery life is ambient temperature.

General ambient temperature required by the general battery manufacturer is between 20-25 ° C. At present, the battery used in the UPS power supply is generally maintenance-free sealed lead-acid battery, and the design life is generally 5 years, which can reach the battery manufacturer's requirements. Second, the order of switching machine In order to prevent the load caused damage to the UPS in the startup moment, the UPS should be supplied to the UPS, so that it will open the load one by one, then open the load, which prevents the load current pair.

UPS's impact, enabling UPS's service life. The shutdown order can be seen as the reverse process of the boot order, first turn off the load one by one, and close ups close. Third, the battery-maintaining the UPS power battery pack will exist self-discharge phenomena.

If long-term placement does not need to cause damage to the battery pack, it is necessary to charge and discharge regularly. If used is the maintenance-free absorption electrolyte system battery, there will be no gas during normal use, but if the user uses improper use, the battery pack will occur, and the gas will appear, and the internal pressure of the battery pack is increased. The situation is severe, and the battery can be pulled, deformed, and the leakage is even cracked.

If the user finds this phenomenon, the battery pack should be immediately replaced. With the market demand, the UPS power battery has been widely used in various industries. The UPS battery has become the pillar of this special system.

When the commercial power supply is abnormal, the battery will chemically convert the chemical energy to electric energy, transported by inverter power supply in UPS. In the load to ensure the uninterruptible operation of the electrical equipment, ensure the use or information security of the equipment. .
