摘要
介绍了大型工厂10/0.4kV变电所中进线和母联ATS的要求与特点,及不停电倒闸装置的功能。阐述了变电所中低压进线断路器、母联断路器、出线断路器的选择、整定及保护配合等设计要点,以供设计人员参考。
The demands and characteristics of ATS for incomer and bus-tie,and the functions of the disconnecting of lines without power failure in 10/0.4 kV substation for large plant were introduced.Selection,setting and protective coordination for LV incomer,bus-tie and feeder circuit breakers in substation were expounded.It could provide references for designers.
