GPO-3 application of UPS in power transmission and distribution

UPS, i.e. uninterruptible power supply, is a system equipment that connects the storage battery with the host and converts the DC power into commercial power through the host inverter and other module circuits. When the mains power input is normal, ups will stabilize the mains power and supply it to the load for use. At this time, UPS is an AC electric voltage regulator, and it also charges the battery in the machine; When the mains power is interrupted (accidental power failure), ups will immediately supply 220V AC power to the load through inverter switching to keep the load working normally and protect the load software and hardware from damage. UPS equipment can usually provide protection against high or low voltage. Flame retardant requirements for insulation materials are V0 level, high strength, temperature resistance and other characteristics.
