不换位的同杆架设或部分同杆架设双回输电线路有一回停运检修时

该线路的接地开关需切断较大的电容性和电感性感应电流。笔者对此进行了计算、分析和实测

并提出了选择这类接地开关的原则。

When one of untransposed double- or segment double-transmission line is to be changed to function after maintenance is finished

grounding switch of that line should break capacitive and inductive current induced from the adjacent line. In this paper

calculation

analysis and measurement of the current are presented

and principles of choosing grounding switch in this situation is proposed.
