Analysis of 10 kV Switch Tripping Faults Based on Message Sequence Timing

Based on time sequence data and control circuitry, this study summarizes the time sequence diagrams of three typical tripping faults: secondary circuit tripping, mechanism tripping, and instant opening after closing.The analytical method has been effectively applied in practical maintenance, assisting maintenance personnel in promptly determining investigation directions,reducing fault investigation and processing time and improving the reliability of power supply in distribution networks
