摘　　要：CPI速调管高功放作为全国地球站主用功放,使用范围广大。通过我站15年的使用经验来看,该功放性能稳定,美中不足的是高功放外部接口板损坏量较大。本文整理出外部接口板易损处原理图,试图从本站4块接口板维修实例,总结出经验,希望能为广大广播电视地球站提供一定的借鉴。As main power amplifier of earth stations in China,CPI klystron high power amplifier is widely used.Through 15 years of use experience in our station,we find that power amplifier performance is stable,but external interface board of high power amplifier is quite vulnerable.This paper sorts out schematic diagram of vulnerable point of external interface board and tries to summarize some experiences from maintenance examples of 4 interface boards of this site.It is hoped to provide certain references for other radio and television earth stations.
