Problems solved by technology

[0002] Every year, a large number of mobile communication base stations and repeaters are struck by lightning, most of which are induced lightning. The strong surge current is introduced into the base station or repeater and other equipment through the power supply line, causing equipment damage
Although there are various protection switches and grounding measures, they are basically passive lightning protection measures, which only work when they are struck by lightning. Since it takes time for these measures to work, many devices are still damaged by lightning every year.

Abstract

The invention discloses a lightning isolation device, which comprises a lightning monitoring center platform (3), at least one monitoring terminal component (1) and an isolating switch (2) corresponding to the monitoring terminal component (1). One end of each monitoring terminal component (1) is connected with the isolating switch (2), and the other end of the monitoring terminal component is connected with the lightning monitoring center platform (3). Simultaneously, the invention also discloses a lightning isolation method using the lightning isolation device. The method and the isolation device can previously cut off the connection between a power supply circuit and electric equipment immediately before lightening occurrence in the location so as to effectively reduce the fault rate of the electric equipment such as a base station or a repeater and the like during lightning strike.

Description

technical field [0001] The invention relates to a lightning isolation method and a used lightning isolation device. Background technique [0002] Every year, a large number of mobile communication base stations and repeaters are struck by lightning, most of which are lightning-induced strong surge currents that are introduced into base stations or repeaters and other equipment through power supply lines, causing equipment damage. Although there are various protection switches and grounding measures, they are basically passive lightning protection measures, which only work when they are struck by lightning. Since it takes time for these measures to work, many devices are still damaged by lightning every year. For this reason, mobile communication operators urgently hope to have a kind of lightning isolation method and used isolation device that actively disconnect the electrical equipment from the power supply line before the lightning comes.
