Abstract: Most of the faults of switchgear in distribution network are caused by the faults of its operating mechanism. Via adding sensors on the integrated column switch to monitor the working current of making and breaking coil and energy-stored motor and combining with the changes of the environmental temperature and humidity etc feature information, this paper proposed a kind of multi-information state monitoring and fault diagnosis method for the operating mechanism. By comparing the multiple current ripple changes of the same operating mechanism and combining with changes in environmental temperature and humidity, this paper forecasted the trend of performance change of the operating mechanism, diagnosed the performance status of the operating mechanism comprehensively, so that the potential equipment failure hidden danger was found out in advance and the corresponding maintenance suggestions were given, which is helpful to understand the state indicators of the switchgear comprehensively, reducing the failure rate of the switchgear.
Key words: distribution switch; operation mechanism; condition monitoring; fault diagnosis
