为保证M2W100KW发射机安全稳定运行,避免设备损坏和播出的中断,在对M2W中播广播发射机供电系统研究的基础上,结合日常工作和维护中发射机出现的问题,对发射机多次出现的驱动级电源故障、VDD电源监测丢失故障和控制系统死机三种故障现象进行了分析说明,从原理上分析了故障产生的原因,并针对三种故障相应实施的具体技术改造方案进行了论述,报告了实施后取得的成果,建议有同类型发射机的维护人员考虑这样的技术改造。
In order to ensure the safe and stable operation of the M2W100KW transmitter and avoid equipment damage and broadcast interruption, based on the research of the M2W broadcast transmitter power supply system, combined with the problems of the transmitter in the daily work and maintenance, The power failure of the driver stage, the loss of VDD power monitoring and the crashes of the control system were analyzed and explained. The reasons for the failure were analyzed from the principle and the specific technical transformation schemes for the three kinds of faults were discussed , Reported on the results achieved after the implementation of the proposed type of transmitter maintenance staff to consider such a technological transformation.
