Description

UPS trouble power is from input device

Technical Field

The utility model belongs to the technical field of the power reliability technique and specifically relates to a UPS trouble power supply is from throwing device.

Background

The UPS, i.e., a Uninterruptible Power Supply (uninterruptable Power Supply), is an energy storage device that connects a storage battery (mostly a lead-acid maintenance-free storage battery) with a host, and is a constant-voltage constant-frequency UPS that uses an inverter as a main component. The power supply device is mainly used for providing stable and uninterrupted power supply for partial equipment with higher requirements on power supply stability, and comprises a single computer, a computer network system, a data center or other power electronic equipment (such as an electromagnetic valve, a pressure transmitter and the like).

The UPS is respectively connected with the mains supply and the load, so that the power failure problem of the mains supply is solved, and the reliability of load power supply is ensured. When the commercial power is interrupted or power is cut off in an accident, the energy stored in the storage battery is released and changed into the alternating current to supply power to the load through the inverter, so that the load can maintain normal work, and the soft and hardware of the load are protected from being damaged. Although the UPS solves the problem of mains power outage, when the UPS itself fails, the reliability of the load power supply cannot be guaranteed.

Most of the existing UPS devices are internal integrated devices, and years of experience of running and overhauling of Huaneng Taicang power plant equipment shows that when an internal fault occurs in a UPS, although the commercial power input into the UPS is normal, the output of the UPS is lost, and finally the load is lost. In recent abnormal accidents, the UPS device inside the primary fan frequency converter fails, so that the industrial personal computer and the PLC of the frequency converter lose power, and the frequency converter trips and cannot switch power frequency operation and trip a 6kV switch due to the fact that the control cabinet controls the power supply to lose power, so that the serious consequence of unit shutdown is finally caused, and great economic loss is generated.
