Abstract

The invention discloses a lightning overvoltage protection method and system for AC power input in a remote machine room, which includes a power environment monitoring system and an AC power switch; the AC power switch is connected in series between the AC input end and the AC power distribution in the remote machine room Between the input ends of the box, the control end of the AC power switch is connected to the switch control signal output end of the monitoring equipment; the monitoring center used to obtain the lightning warning information from the local meteorological department in the computer room passes through the communication transmission equipment, communication The access device sends a control instruction to the monitoring device, and the monitoring device sends an execution command to the AC power switch according to the control instruction to control the AC power switch to be turned off or on. The present invention can protect communication equipment such as power supply, monitoring, transmission, exchange, access, base station, air conditioning, lighting and other equipment in the computer room from the impact of lightning overvoltage from the AC power line through the power environment monitoring system and the isolation and insulation method.

Description

technical field [0001] The invention relates to the technical field of lightning overvoltage protection, in particular to a lightning overvoltage protection method and system for inputting AC power in a remote communication room or a base station powered by a DC power supply unit containing an animal battery pack. Background technique [0002] According to the statistics of lightning strikes in various communication equipment rooms, at present, more than 60% of lightning failures in remote equipment rooms and communication base stations are caused by lightning overvoltage introduced by AC power supply. [0003] At present, the AC power input of the communication room mainly adopts the equipotential principle for lightning overvoltage protection. As shown in Figure 1, for a single-phase AC power supply, overvoltage protection is achieved by installing a Class B surge protector in the AC distribution box and a Class C surge protector in the DC power supply equipment. As shown...
