| Abstract: | Aiming at the automatic trip event of 35 kV 3AP1-FG Type breaker after its closing, and by disassemble inspection of the abnormal breaker after outage, it is analyzed that main reason of the automatic trip was the deflection of the tripping coil ejector pin which caused the stuck of the ejector pin and then caused the tripping pawl in its trigger status. Treatment methods and preventive measures are proposed according the problem. |
