Product Details

避雷器泄漏电流数字化远传表计

 

 

产品概述

 


    表计式避雷器在线监测器主要有取样阀片、硅桥式整流器、高压电容器、电磁计数器、毫安表等元件组成。它是利用通过避雷器的放电电流,在阀片(非线性电阻)上产生的电压,经硅桥式整流对电容器充电,向电磁计数器放电,每放一次记录一次,来实现记录避雷器的动作次数。
 

    避雷器在线监测器采用数字式显示,该显示具有指示清晰,便于观察等优点;计数循环次数为0~99每100次一个循环,这有利于将短期内通过避雷器的雷电次数较完整的记录下来。

    避雷器在线监测器是串联在避雷器下面,既可用来记录避雷器动作次数,同时又可以通过毫安表监测避雷器在运行电压下的泄露电流的一种装置。用于330KV及以下等级的避雷器,使用地点的环境条件与相连的避雷器相同,它不适于有严重污秽和有剧烈震动的地方;采用氧化锌阀片,电气性能有较大提高。
