摘要

针对220kV输电线路融冰前需检修人员高空搭接融冰电缆头的弊端

提出并研制了一种220kV融冰接地隔离开关。融冰实践证明该设备操作简便

可快速打通融冰通道

完全消除了检修人员高空作业的安全风险

满足大电流融冰要求。

Abstract

Aiming at the disadvantages that maintenance personnel need to lap the ice-melting cable head at high altitude before ice-melting of 220 kV transmission lines

a new type of disconnector with both ice-melting and grounding functions is proposed and developed in this paper. Through the practical test of ice-melting

it is proved that the equipment is easy to operate

which can quickly open the ice melting channel

completely eliminates the safety risk for maintenance personnel working high above the ground

meets the requirements of high current ice melting.
