Abstract
In order to improve power supply reliability of secondary equipment in power plants and stations,it is needed to a-dopt multi-power supply switching circuit,while design defects of multi-power supply switching circuit may cause impact on stability of load voltage and power source system. Therefore,combining one case of adopting diode for dual power supply switching and by means of field test,this paper analyzes and finds out reasons for causing defects of two sections of direct current (DC)bus interconnection by power source switching circuit. It presents an impeccable transformation scheme and proposes various problems need attention and precaution measures. In view of that existing job specifications do not involve in detailed check on power source switching circuit,it also proposes multi-item simple and reliable inspection measures so as to prevent unsafe impact on load and power source system from power supply switching.关键词
