Abstract

The invention can avoid power supply with phase-dislocation, phase-loss, over-voltage and under voltage to input to next power utilization system. It can inhibit surge interference of power source, and can send out local or remote alarm signal, when power input or UPS failure. It can record the time of power failure, and can manually cancel the alarm signal, and can reset to standby state when power supply recovers.

Description

technical field [0001] The invention relates to the technical field of a dual-circuit electric automatic switching cabinet for phase sequence monitoring Background technique [0002] Bank securities, post and telecommunications, aerospace, national defense and military industry, and large-scale computing centers or network communication centers in clinical medicine all require reliable and precise power supply. The power supply system generally uses multiple online UPS+dual mains with redundant backup. + High reliability configuration mode of multiple fast-start diesel generators with redundant backup. In the low-voltage power distribution before UPS, the conversion between the two-way mains and between the mains and the generator generally adopts mechanical and electronic Automatic interlocking device ATS with interlocking function. In these highly reliable and sophisticated low-voltage power supply and distribution systems, some random problems that affect power quality a...
