摘　　要：中低压配电网中避雷器因长期承受工频电压、冲击电压,同时,由于环境条件的影响,避雷器的阀片会受潮劣化,当有过电压产生,通过避雷器内阀片的电流迅速增大,可能会导致避雷器产生热崩溃,甚至使避雷器爆炸。本文在简述几种常见避雷器设备性能特点的基础上,介绍了一种带间隙的脱扣器,通过其结构和技术指标,说明新型带间隙式脱扣器的工作原理,并介绍了避雷器与脱扣器的安装方式。In medium and low voltage distribution network,arresters withstand power frequency voltage and impulse voltage for a long time.At the same time,due to the influence of environmental conditions,the valve plates of arresters will be damped and deteriorated.When overvoltage occurs,the current through the valve plates of arresters will increase rapidly,which may lead to thermal collapse of arresters and even explosion of arresters.On the basis of briefly describing the performance characteristics of several common lightning arrester equipment,this paper introduces a kind of lightning tripper with clearance.Through its structure and technical index,it explains the working principle of the new type lightning tripper with clearance,and introduces the installation mode of lightning arrester and lightning tripper.
