摘要

本文分析了GIS双母线电站母线侧隔离开关的特点

指出在倒换母线过程

它们要切断电弧的必然性;计算了110kVGIS中此种隔离开关切环流的数值、暂态恢复电压上升速度和工频恢复电压大小

提出设计切环流隔离开关需采取的措施。

Abstract

This paper discusses the salient features of the disconnector being nearby a busbar in double busbar substation of GIS

and show the inevitability of interrupting arc in the change-over busber process. It had been calculated that the maximum value of interrupting loop line current

the rate of rise of recovery voltage and the power frequency recovery voltage. A new type disconnector wtih capacity of interrupting loop line current in GIS had been designed and tested in the laboratory to verify its properties achieving the desired results.
