摘　　要：随着中波广播发射机的不断发展,供电电源变压器从原来的5 kW直接扩展为10 kW,大大提高了传输的效率。但是,进入冬季以后,受各种环境因素的影响,中波发射机开始出现自动关机的现象,主要表现为电源故障问题。因此,针对DM 10 kW中波广播发射机电源故障问题展开了分析研究。With the continuous development of medium-wave broadcast transmitters,the power supply transformer was directly expanded from the original 5 kW to 10 kW,which greatly improved the efficiency of transmission.However,after entering winter,due to various environmental factors,the medium-wave transmitter begins to automatically shut down,mainly due to power failure problems.Therefore,the power failure problem of DM 10 kW medium-wave broadcast transmitter is analyzed and studied.
