摘要
电力电缆的中间接头的故障短路事故是影响电缆隧道安全运行的最主要因素之一。而电缆中间接头故障提早发现和准确判断,是降低电缆隧道事故的关键。笔者结合自己的工作实践,总结出"温差法"判断电缆中间头故障的方法,对企业安全供电能提供一些借鉴。
Short circuit trouble of the middle connection of electric power cable is the main factor to fluence safe operation of the cable tube. Find and judge the connection incident of electric power cable end is the key to reduce the cable tube trouble. The writer summerizde the temperature differen method to judge the connection incident of electric power cable end according to the working expel ence. It can give some help to supply electric power safely for company.
