摘要
在数字幅度调制(Digital Amplitude Modulation,DAM)10 kW中波广播发射机中,功放模板占据很重要的位置.中波广播发射机运行时,功放模板发生故障的概率非常大.介绍了同一位置功放模板损坏时的故障分析及排除过程,并介绍效率线圈的工作原理.
Abstract
In the Digital Amplitude Modulation(DAM)10 kW medium wave broadcast transmitter,the power amplifier template occupies a very important position.When the medium wave broadcast transmitter is running,the probability of power amplifier template failure is very large.In this paper,the fault analysis and troubleshooting process of the same position power amplifier template is introduced,and the working principle of the efficiency coil is also introduced.
