Abstract

The invention provides an isolation switch monitoring method and system, relates to the technical field of electrical equipment, and can solve the problem of inaccurate monitoring due to the fact that the state of an isolation switch is determined only through the on-off state of an auxiliary node in the prior art. The specific technical scheme is as follows: the method comprises the following steps: acquiring an opening or closing operation signal of the isolating switch; obtaining an identification result of the reference identification device and an identification result of the at least one auxiliary identification device within a preset time according to the operation signal; and determining the current state of the isolating switch according to the identification result of the reference identification device and the identification result of the at least one auxiliary identification device. The method is used for monitoring the state of the isolation switch.

Description

technical field [0001] The present disclosure relates to the technical field of electrical equipment, in particular to a monitoring method and system for an isolating switch. Background technique [0002] The existing 35kV and above substation open type isolating switch obtains the state of the switch position through the auxiliary contact in the mechanism box, because the auxiliary contact is inside the mechanism box, and after the isolating switch has been running and operated for a long time, the transmission shaft and the conductive arm, etc. The middleware will be mechanically loosened and changed to varying degrees, so monitoring the opening and closing status of the auxiliary contact cannot fully reflect the position status of the conductive arm and the moving contact of the disconnector, and there is a problem of inaccurate monitoring. Contents of the invention [0003] The embodiments of the present disclosure provide a method and system for monitoring an isolatin...
