母联电力电子开关异常分断问题分析

Analysis on abnormal break of bus coupler power electronic switch

针对船用母联电力电子开关异常分断,通过构建故障树,从短路、供电不足、误报警、连接不良等底事件对问题发生的根本原因进行分析,根据分析结果采取有效措施,验证了分析过程的有效性。

Aiming at the abnormal break of power electronic switch in a certain type of marine bus coupler,this paper analyzes the root causes of the problem from the bottom events such as short circuit,insufficient power supply,false alarm and bad connection by constructing a fault tree,according to the analysis results,effective measures were taken to verify the effectiveness of the analysis process.
