摘要
DAM系列中波发射机是目前中波发射台普遍使用的一种发射机机型。DAM中波发射机具有完善的故障保护功能,出现故障时,可以按照故障类型做出相应的故障处理,并给出故障指示,避免故障造成更大的损失,为机务人员提供故障原因和查找方向。基于此,以GZ-GS10 kW发射机为例,对DAM中波发射机的故障分类、故障现象及分类检修方法进行详细论述。
DAM series medium wave transmitter is a transmitter model commonly used in medium wave launch pad at present.Due to the comprehensive fault protection function of the DAM medium wave transmitter,when a fault occurs,corresponding fault handling is made according to the type of fault,and fault indications are provided to avoid greater losses caused by the fault,and to provide maintenance personnel with the cause of the fault and direction for finding the cause.This article takes the GZ-GS10 kW transmitter as an example to provide a detailed discussion on the fault classification,fault phenomena,and classification maintenance methods of DAM medium wave transmitters.
