摘要
Abstract
In view of the mis-opening and closing accident of a 1000 kV isolating switch during the local opening after the motor being burnt during the closing process,it analyzes the problems in the application range of auxiliary contacts in different time sequence and the control circuit of isolation switch with single-phase linkage and separate phase operation.It proposes solutions to strengthen the re-quirements of the isolating switch control circuit,clarify the action timing of the auxiliary contacts of the isolating switch,optimise the relationship between the self-holding control circuit and the motor power circuit,and standardise the operational processes of mainte-nance personnel,ensuring the safe and stable operation of the isolating switch,providing a reference for the circuit design and opera-tion maintenance of similar isolating switches.关键词
