DX型中波发射机电源监测及告警电路的设计

DX-Type Medium-Wave Transmitter Power Supply Monitoring and Alarm Circuit Design

针对发射机PB电源保险易发生熔断故障,设计了一个电源保险监测及报警装置,对发射机电源通路上的此类保险进行实时的监测,并显示各路状态,这样就能及时发现电源保险故障并准确确定故障位置,大量节省排障时间,为安全播出提供更好的保障。

Aiming at the power supply of transmitter PB insurance prone to fuse failure, an insurance power monitoring and alarm device is designed, which can real - time monitor such insurance on the transmitter power path, and display the brightest state. So that the power insurance failures are promptly discovered and the fault location is accurately determined, which saves a lot of troubleshooting time and provides better protection for the safety broadcast.
