摘　　要：高频阻波器作为电力线载波通道中的一个重要环节,直接影响着载波信号的传输质量。通过分析高频阻波器的工作原理,探讨高频阻波器出现故障时对高频保护的不良影响,结合现场实际,给出了几种高频阻波器故障的检测方法,以便及时准确地发现并排除故障,有效避免高频阻波器故障对载波通信及高频继电保护装置的干扰,防止高频保护装置不正确动作,从而保证电力系统的稳定运行。The high frequency wave trapper, as an important link in a power line cartier channels, has an immediate influence on the quality of signal transmission. Through analysis of the working principle of high frequency wave trapper, this article makes analysis of the negative effect on the high frequency protection brought by the breakdown of high frequency wave trapper. In view of the scene reality, several detection methods are given to detect the breakdown of high frequency wave trapper so as to remedy the fault immediately and accurately, and avoid the disturbance to the carrier communication and the high frequency relay protection installment because of the breakdown of high frequency wave trapper, and ensure the stable operation of the power system.
