DX系列10kW TSD-10中波数字调制广播发射机有着工作性能稳定可靠、故障率低等优点,但由于电路技术精度高,半导体器件多,线路密布复杂,对外界环境温度、灰尘、静电、信号等因素的影响也十分敏感,有时候也会出现一些我们意想不到的故障。本文以新疆广电局节传中心762台TSD-10 10kW中波数字调制广播发射机出现的“B-”电源故障检修一例向大家做一浅析。 The DX series 10kW TSD-10 medium wave digital modulated broadcast transmitter has the advantages of stable and reliable working performance and low failure rate. However, due to the high precision of circuit technology, many semiconductor devices and dense circuits, the ambient temperature, dust, static electricity and signal The impact of other factors is also very sensitive, and sometimes we will have some unexpected failures. In this paper, the Xinjiang Broadcasting Bureau Transmission Center 762 Taiwan TSD-10 10kW digital modulation broadcast transmitter appeared “B-” power supply troubleshooting a case to do a brief analysis.
