摘要
介绍了高频通道的构成及其原理,阐述了线路发生故障多为高频通道故障所致,通道堵塞、通道质量低劣是影响高频保护不能正确动作的主要因素,提出了高频通道故障处理的方法,可供同行参考。
The constitution and principle of high frequency channel is introduced and line breakdown is caused by high frequency channel fault. The channel blockage and inferior-quality channel are majors reasons for the incorrect operation of high frequency protection. The method of fault processing is put forward,which gives reference for engineering counterparts.
