UPS uninterruptible power supply daily maintenance

UPS uninterruptible power supply daily maintenance

First, A UPS power supply in normal use, the mainframe maintenance work is very little, mainly dust and regular dust removal.Especially in the dry climate area, there are more ash particles in the air, and the wind in the machine will bring the dust into the machine to deposit. When the air is wet, it will cause the control disorder of the main engine and cause the working disorder of the main engine, and inaccurate alarm will occur. A large amount of dust will also cause bad heat dissipation of the device.Generally, it should be cleaned thoroughly once every quarter.The second is in the dust removal, check the connection and plug parts are loose and contact is not strong.

Second, although the energy storage battery pack is currently using the maintenance-free battery, but this is only exempt from the previous measurement ratio, ratio, regular addition of distilled water work.However, the influence of external working state on the battery has not changed, and the influence of abnormal working state on the battery has not changed. The maintenance and overhaul work of this part is still very important. A large number of maintenance and overhaul work of UPS power system is mainly in the battery part.

1. The work of the energy storage battery is all in the floating charging state, in which case it should be discharged at least once a year.Before discharging, the battery pack should be charged evenly to achieve the balance of the whole battery group.Be clear about the behind batteries that already exist in the battery pack before discharging.In the discharge process, if one reaches the discharge termination voltage, the discharge should be stopped, and the discharge should be continued to eliminate the backward battery before discharging.

2, check discharge, not the first pursuit of the release capacity of the percentage, but to pay attention to the discovery and processing of backward batteries, after the backward battery treatment and then check the discharge experiment.This prevents accidents in which the backward battery deteriorates into an anti-electrode battery during discharge.

3. At ordinary times, each group of batteries should have at least 8 batteries as labeled batteries, as a reference to understand the working condition of the whole battery pack. The labeled batteries should be measured regularly and recorded.

4. The items that need to be checked regularly in daily maintenance include: cleaning and detecting the voltage and temperature at both ends of the battery;Whether the connection is loose, corrosion phenomenon, test the pressure drop of the connection bar;Whether the battery appearance is intact, there is no shell deformation and leakage;Whether there is acid mist escaping around the pole column and the safety valve;Host equipment is normal.

Third, when the UPS battery system failure, should first find out the reason, distinguish is the load or UPS power system;Is it the mainframe or the battery pack?Although the UPS host has fault self-inspection function, but it is opposite to the wrong point, it is very convenient to replace the parts, but to repair the fault point, still need to do a lot of analysis, detection work.In addition, if a fault occurs in the self-test part, the fault content displayed may be wrong.

Forth, If the fault of the main engine is breakdown, breakdown of safety or burnout of devices, it is necessary to find out the reason and troubleshoot the fault before it can be restarted, otherwise the same fault will occur successively.

Fifth, when the battery voltage antipole, large pressure drop, pressure difference and battery acid mist leakage phenomenon, should adopt the method of corresponding recovery and repair in time, for not to replace of recuperation and repair, but not the different battery capacity, different performance, different manufacturers together, otherwise may be detrimental to the entire group battery.The expired battery pack should be replaced in time, so as not to affect the host.
