UPS (
Uninterruptable Power System/Uninterruptable Power Supply)
Power supply is
The storage battery (mainly lead-acid maintenance-free storage battery) is connected to the host computer, and the DC power is converted into the mains system equipment through the module circuit of the host inverter.
UPS and
DC power supply is an important power supply support device for enterprises. The traditional maintenance management includes: 1 Daily inspection appearance, regular battery activation, etc.
2 transformation or the use of replacement equipment, use only load test battery performance. This kind of management can avoid the inadequacies of traditional replacement methods and achieve good benefits.
In the process of using an uninterrupted power supply system, people often think that the storage battery is maintenance-free and does not pay attention. However, data shows that due to battery failure
The ratio of UPS mainframe failure or malfunction is about 1/3. This shows that strengthening
The correct use and maintenance of the UPS battery will prolong the service life of the battery and reduce it.
The failure rate of UPS systems has become more and more important. In addition to matching the regular brand battery, the following aspects should be used to properly use and maintain the battery:
(1)
Dust is carried into the machine and deposited.
When the air is wet, it may cause the host to control the disorder to cause the host to work abnormally, and an inaccurate alarm will occur. A lot of dust will also cause the device to have poor heat dissipation. It should be thoroughly cleaned once every quarter. The second step is to check the looseness and loose contact of each connector and connector during dust removal.
(2 ) Although the energy storage battery packs are used
Maintenance-free battery, but this only eliminates the previous measurement, ratio, and timing addition
Distilled water work. But external factors
The influence of the working state on the battery has not changed, and the influence of the abnormal operating state on the battery has not changed. This part of the maintenance and repair work is still very important. A large number of maintenance and repair work of the UPS power system is mainly in the battery part.
The work of the energy storage battery is all in the floating state, in which case discharge should be performed at least once a year. The battery pack should be charged prior to discharge to achieve the balance of the entire battery pack. Be aware of the battery that is already present in the pack before discharging. If any one of the discharge termination voltages is reached during discharge, the discharge should be stopped. Continue discharging to eliminate the backward batteries and then discharge them.
Checking for electrical discharges is not the first pursuit of the percentage of discharged capacity. Instead, attention must be paid to the discovery and handling of backward batteries. This can prevent accidents, so as to avoid backward battery deterioration in discharge is a reverse battery.
