我台使用的CS－型10千瓦发射机，出现输出功分低的故障，影末实测输出功率P＝3kW，S＝1．2而影末阴流却高达2．4A，相当输出10kW时的数值，栅流20mA，帘栅流15mA。根据故障现象首先检测影本静态工作点，关掉激励器，这时影末阴流为1A，栅流、帘栅流均为零。可见影末静态工作点 I use the CS-type 10-kilowatt transmitter, there is a low output breakdown, video at the end of the measured output power P = 3kW, S = 1.2 and shadow at the end of the shade but up to 2.4A, the equivalent output of 10kW Value, gate current 20mA, screen current 15mA. According to the phenomenon of the phenomenon of the first detection of static static working point, turn off the exciter, then the end shadow shade 1A, gate flow, curtain flow are zero. Can be seen at the end of static work point
