缩短移动式直流融冰站内取电工前准备套装工具的研制

Development of a Set of Tools to Shorten the Preparation of Electrician in Mobile DC Ice Melting Station

2018年10月,红河供电局开展了110 kV线路移动式直流融冰应急工作方案的联合演练,在演练过程中发现电缆在与10 kV电源侧取电连接时,电缆接线板眼孔过大与电源设备不匹配,此类连接方式可造成局部发热致使损坏设备本体,导致融冰过程中断。云南电网公司红河供电局输电线路八班根据现场实际需要出发,研制了电缆接线板与电源侧相连接的通用型搭接线板,解决了直流融冰过程中,因接头尺寸不匹配存在的接头发热的问题。

In October 2018,Honghe Power Supply Bureau carried out a joint drill on emergency work plan for mobile DC ice melting of 110 kV lines.During the drill,it was found that when the cable was connected to the 10 kV power supply side,the hole of the cable terminal board was too large to match the power supply equipment.Such connection mode could cause local heating,damage the equipment body and interrupt the ice melting process.According to the actual needs of the site,the eighth shift of transmission line of Honghe Power Supply Bureau of Yunnan power grid company developed a universal lap line board connecting the cable terminal block and the power supply side to solve the problem of joint heating due to the mismatch of joint size during DC ice melting.
