How to solve the fault of UPS battery pack?

What should I do if the UPS battery pack fails? Recently, the case of UPS and backup battery pack failures occurred at the same time during the mains switchover process is summarized and shared with you. Fault phenomenon: UPS input power is interrupted during the mains switching process, and the working state is abnormally switched from battery inversion to bypass power supply. At the same time, the UPS unit panel displays abnormal bus voltage, BCB open circuit and other abnormal alarms, and sounds an alarm at the same time; UPS battery When abnormal switching occurs, it is determined through on-site inspection that there is no impact on the output of the back-end load. On-site operation and maintenance personnel immediately take the following measures to prevent abnormal power outage of the external mains power and cause abnormal power outage of the load in the UPS room. 1. Immediately contact the UPS manufacturer’s technical personnel for on-site inspection and technical support; 2. Immediately contact the UPS battery manufacturer’s technical personnel for on-site technical support and inspection of the battery pack; 3. Immediately convert the UPS operating state to the main normal inverter power supply mode, and use Temporary cables provide temporary treatment for abnormal switching of UPS bypass power supply to prevent interruption caused by abnormal external power supply. Generally speaking, to solve the possible faults of UPS batteries should be dealt with according to the classification of the faults that occur. Generally speaking, they are divided into UPS host failures, battery failures and external irresistible factors. For UPS host failures, most of the internal parts of the UPS power supply have problems that need to be repaired and dealt with in time. At this time, they must be reintegrated according to the corresponding conditions, and the equipment that may be burned out must be reprocessed and replaced. The newly installed battery is a new battery that has just left the factory, so there are few problems caused by the battery itself. In summary, most of the problems are due to improper installation between the battery and the battery. Some wiring problems with the UPS battery connection or the connection problem of the battery cabinet and the UPS host wire It is very likely that the power supply of the equipment is unstable, and it is not possible to directly provide sufficient power support for the Santak UPS power supply and back-end load. At this time, we need to check whether the external circuit of the battery pack is damaged, whether the connection line between the internal batteries is correct, and whether the total voltage of the UPS battery pack is too large or too small, so as to clarify the solution.
