摘　　要：配电板和交流不间断电源装置为电源转换装置提供主用、备用两路电源输入,简单的供电关系却造成了某船电源转换装置对电网绝缘监测干涉的现象。通过对干涉现象分析,结合设备之间的内在联系和电源转换装置两路电源转换原理以及绝缘监测的工作原理,找到固态开关的两路电源转换是造成干涉现象的根源,通过试验验证,提出可行的解决方案。Switchboard and AC uninterrupted power supply device provide the main and backup power supply for a power convertor device,but the simply power supply relationship causes the power network insulation monitoring interference by the power convertor device aboard.Through the analysis of the interference phenomena,and in combination with the internal relation between the equipments and two loop power convertion working principle of power convertor device,as well as insulation monitoring working principle,it is found that two loop power convertion of the solid-state switch is the original reasons for causing the interference.Through test and verification,the feasible solution schemes are proposed thereafter.
