How to deal with the UPS battery pack fault? Recently, the UPS and standby battery packs encountered at the same time, there is a fault case, and it is now summarized. Fault Phenomenon: UPS inputs the power supply interrupt during the market switching process, the working state is switched from the battery inverse transition to the bypass supply, and the UPS unit panel appears abnormal alarms such as the bus voltage, BCB open circuit, etc., simultaneous alarm; UPS battery An abnormal switching is made, and the on-site inspection is determined that the backend load output is not affected.
The on-site operation and maintenance personnel immediately take the following measures to prevent foreign-market electrical abnormal power outages, resulting in an abnormal power failure of the machine room load in the UPS. 1. Contact the UPS manufacturer's technicians to check and technical support; 2.
Contact UPS battery manufacturers immediately attended technical support and battery pack inspection; 3. Immediately convert the UPS operation status to the main path normal inverter power supply mode, use Temporary cables are temporarily processed for abnormal switching UPS bypass power supply to prevent exports from electrical abnormalities. In general, solving the problem of failure problems that may occur in the UPS battery should be processed according to the fault classification, it is generally divided into a UPS host fault, battery failure, and external irresistible factors.
In terms of UPS host failure, most of the UPS power supply internal components will have timely repair, and this time should be re-organized according to the corresponding conditions, and the equipment that may be burned is subject to re-processing and replacement. The new installation of the battery is very small due to the new battery that is just the factory, the battery itself causes a small fault problem, and most of the content is due to the installation of the battery and the battery to install some line issues or battery cabinets and UPS host wires. It is very likely that the power supply is unstable, and it is impossible to directly support the Shante UPS power supply and the backend load.
At this time, we have to check if the battery pack is damaged, whether the connection between the internal battery is correct, the total voltage of the UPS battery pack is too large or too small, thereby clearly solving the method. .
