全固态PDM发射机典型故障分析

Solid-state PDM transmitter typical fault analysis

随着科学技术的不断进步,电子管设备已经退出历史舞台,取而代之的是PDM、DAM全固态中波广播发送设备.目前我省1KW中波转播台也进一步更新为全固态PDM发射机,由于设备刚刚更新,对新设备不熟悉,所以当设备出现故障时无从下手,现将我台工作中总结的几种典型故障提供给大家.以供参考.

With the continuous progress of science and technology,the vacuum tube equipment has been replaced by PDM,DAM and all solid-state medium wave broadcasting transmission equipment.At present,the 1 KW medium wave broadcasting station in our province has been further updated to be the all-solid PDM transmitter.As the equipment has just been updated and is not familiar with the new equipment,it is impossible to start when the equipment breaks down.Now would like to offer you some typical failures summarized in the work of our station.For reference.
