摘要
原设计选用三相五线制双电源供电,总电源开关采用四级漏电保护开关,电源转换采用三级接触器,合闸送电,总电源开关跳闸,不能供电。根据规程要求,自制了三相五线制双电源制动转换装置,解决了漏电保护开关跳闸不能正常供电的问题。
The selection of the design of the original three- phase five-wire dual power supply, the powerswitch of the total four - phase leakage protection switching, power conversion usmg three - level contacts, switch on power, with a total power trip switch can not supply. According to the requirements of a point of order, a self- reade three - phase five - wire brake power conversion devices, to address the leakage protection of the trio switch can not be normal power supply.
