摘要

金属氧化物避雷器对并联电容器装置的操作过电压有显著的抑制效果。避雷器推荐使用的接线方式有相地避雷器和端子间避雷器

分别简称为Ⅰ型和Ⅱ型避雷器接线方式。目前电力系统主要采用Ⅰ型避雷器接线方式。本文采用EMTP-ATP程序把Ⅰ型和Ⅱ型避雷器接线方式对并联电容器装置操作过电压的抑制效果进行仿真计算

通过仿真计算得出Ⅱ型避雷器接线方式在分闸重燃时不但可以限制相对地过电压

也可以限制极间过电压

保护效果最好

是一种理想的保护方式

但这种接线方式中的相间避雷器在动作时要吸收很大的能量。

Abstract

Metal oxide surge arrester has a remarkable effect in suppressing the switching overvoltage of shunt capacitor device. The wiring mode recommended to use by the arrester includes phase-earth arrester and arrester between terminals

respectively in short is wiring mode of type Ⅰ and type Ⅱ. In this paper

based on EMTP-ATP program

the suppression result of switching overvoltage of shunt capacitor by the wiring mode of type Ⅰ and Ⅱ arrester are simulated and calculated. It is concluded by the simulation and calculation that the wiring mode of type Ⅱ arrester

in case of opening reignition

can not only limit the overvoltage between phases to earth

but also limit the overvoltage between poles

obtain the best result and can be a kind of ideal protection mode. But the arrester between phases with this wiring mode needs to absorb much energy in operation.
