| Abstract: | Aiming at fault of operating cycles counters of LW10B-252 circuit breaker in certain substation,it was proposed that the fault counters were found by using counters' loop air circuit breaker to simulate motion of circuit breaker when the counters loop in good connection.The fault reason of counters in experiment was analyzed,then three solutions were proposed to account for the problem of counter malfunction in effect,such as counter-loop connects to auxiliary switch mormally open contact,the structure of auxiliary switch is adjusted and excellent counters are recommended to be used,with improving safety and stability of power system. |
| Keywords: | circuit breaker operating cycles counter auxiliary switch normally open contact |
