一起高频线路保护误动事故的调查分析
摘要
高频保护最常见的故障经常发生在高频通道上
高频通道元件多组成复杂
任一元件的故障都可能引起保护误动。通过阻波器元件损坏引起保护误动的事故调查
介绍了高频电流信号在高频通道中的传输原理及阻波器输入阻抗特性试验的方法。
Abstract
The most common misoperations of high-frequency protection occur on HF channel.Any component fault could cause protection misoperation.Through investigation of a protection misoperation caused by wave trapper damage
the transmission principle of high frequency current signals in HF channel was introduced and wave trapper input impedance characteristics test were presented.
