摘要

针对同杆并架双回线末端异名相接地的特殊故障形式

以GE公司的TLS1B保护为例

深入分析了常规线路保护的运行缺陷

同时提出了增加信号通道

扩展跳闸允许信号接口的特殊运用方式

较好地解决了该问题

具有一定的参考价值。

Abstract

Aiming at the specific out-phase grounding fault at the end of doublecircuit line on the same pole and taking TLS1B protection of GE corporation for example

the limitation of ordinary line protection is deeply analyzed

a unique application scheme of increasing signal channel and extending tripping enabling signal interface is proposed

with which the problem is solved in a better way. This scheme is possessed of some use value and can be put into application.
