摘要

概括了接地开关开合感应电流的运行工况及同塔双回线路电磁感应与静电感应的产生机理。介绍了葛洲坝电站B类接地开关的选型情况

对AREVA B类接地开关的工作原理及安装调整重点注意事项做了说明。针对安装运行情况

提出了应优化结构设计使B类接地开关在隔离开关的两侧均能安装以及增加SF6气体压力显示装置等建议。

Abstract

The paper summarizes the operation mode of earthing switch switching induced current and presents the mechanism of electrostatic and electromagnetic induction in common-tower double-circuit lines.Introduces the selection of class B earthing switch in Gezhouba Hydropower Station

explains the working principle of class B earthing switch of AREVA and that need to pay great attention to installation and adjustment.According to installation operation condition

the suggestions are as follows

the structure should be optimized so that it can be installed in either side of disconnector

add display unit of SF6 gas pressure and etc.
