Lightning Protection Method for Distribution Lines Near Microwave Towers

Abstract

The invention relates to a lightning protection method of a distribution line near a microwave tower. The method comprises the following steps of: continuously mounting 5 groups of lightning protectors with series-connected clearance lines according to the fact that the distance between the microwave tower and the distribution line is greater than 5 times of the height of a rod tower; and continuously mounting 5 groups of lightning conductors according to the fact that the distance between the microwave tower and the distribution line is less than 5 times of the height of the rod tower. According to the method, electrical equipment near the microwave tower is prevented from being damaged by the thunder introduced from the microwave tower, so that the safe and normal running of the line is not influenced; and the analysis on the line running is performed conveniently. As a result, based on the overall consideration of engineering cost, construction, maintenance and other factors with the lightning protection effect, the most economical lightning protection effect is achieved.

Description

technical field [0001] The invention relates to a lightning protection method, in particular to a lightning protection method for a power distribution line near a 10kV microwave tower, and belongs to the field of electric power applications. Background technique [0002] In recent years, communication equipment has been widely used. In order to enhance the coverage area of ​​communication signals, more and more microwave towers have been built. Because microwave stations need power, they are generally built near power distribution lines. The microwave tower is generally 50-80 meters higher than the building. From the perspective of atmospheric overvoltage, it is a lightning-inducing device like a lightning rod. Once a microwave tower is struck by lightning, it can simultaneously cause lightning overvoltage in multiple parts within a relatively large range, resulting in power distribution near the microwave tower. Lines and electrical equipment are damaged due to overvoltag...
