栅控行波管发射机打火故障分析及抗打火措施

Analysis of Ignition Failure of Grid-Controlled TWT Transmitter and Anti-Ignition Measures

发射机是雷达系统的重要分机,其故障率约占雷达系统故障率的50%,而发射机打火故障又占发射机故障率的85%以上。因此发射机故障率的高低直接影响着雷达系统的可靠性。针对某型雷达发射机发生打火故障的机理进行了分析,针对性地采取了抗打火报护措施,使得发射机故障率明显下降。

The transmitter is a key part of the radar system,and its failure rate accounts for about 50%of the failure rate of the radar system,while the ignition failure of the transmitter accounts for more than 85%of the failure rate of the transmitter.Therefore,the level of transmitter failure rate directly affects the reliability of the radar system.Aiming at the ignition failure of a certain type of radar transmitter,the mechanism of the failure,and puts forward anti ignition protection measures is analyzed,which significantly reduces the failure rate of the transmitter.
