摘要

采用电磁暂态程序ATP-EMTP计算了宝钢220 kV GIS变电站进线落雷时GIS内断路器、隔离开关、母线以及出线套管和变压器上的雷电过电压

比较了不同落雷地点和运行方式下的雷电过电压

分析了金属氧化物避雷器（MOA）的防雷效果。研究表明

雷电过电压小于GIS内设备及变压器的雷电冲击绝缘水平

接线简单的运行方式雷电过电压最严重

现有MOA可以对设备进行有效保护。

Abstract

The lightning over-voltages on circuit breaker（CB）

disconnecting switch（DS）

bus bar

bushings and transformers were calculated by software ATP-EMTP when lightning waves intrude into 220 kV Baoneng Gas Insulated Substation.The lightning over-voltages of different running modes and lightning strike points were compared

and the effect of MOA on over voltages was analyzed.The result shows that the lightning over voltages are below the BIL of transformers and other equipments.The simpler the connection is

the more serious the over voltages of this mode are.The existing MOA can provide reliable protection for all equipments.
