摘要

研究了110、220kV城网GIS中ZnO避雷器的配置和接线方式.结果表明:1)线路入口避雷器应布置在侵入波前沿

并采用V形连接.为此建议采用合成套ZnO避雷器悬挂在线路终端塔上.2)侵入波过电压水平随进出线电缆长度而变化的关系

因电压等级、网络结线、线路结构和参数的不同而差异较大

电缆末端及GIS是否需加装避雷器

宜通过数值计算和具体分析后确定.

Abstract

The disposition and connection of ZnO arresters in GIS of 110-220kV urban networks are studied. The results show that the arresters at overhead line entrances should be in-stalled at the frontier and connected in "V" mode. The synthetic housing ZnO arrester is recom-mended to be hung at the terminal pole. The relations between incoming surge overvoltage level and cable length are affected by the rated voltage

network configuration

line connection and pa-rameters. Therefore

the disposition of arresters at cable end and GIS busbar are determined by contrete computation and argumentation.
