摘要
介绍220 kV GIS断路器中ABB公司供货的HMB-4.3型液压弹簧机构电机的过流、补压超时信号故障,经分析可知故障是由于HMB-4.3型液压弹簧机构的簧片脱开、接触面脏污、碳刷磨损,导致碳刷与电机转子间的接触不良引起的,并针对故障原因提出了相应的解决措施。
This paper introduces the ABB hydraulic spring drive HMB-4.3 of 220 kV GIS circuit breaker,and describes an over-current, overtime voltage suppling fault on circuitbreaker motor. The analysis results of fault show that dirty contract surface between coal brush and motor rotor, disjoined reed and abrasion of brush can lead to poor contract fault of motor coal brushes and rotor on device HMB-4. 3, which lead to circuit-breaker motor of 220 kV GIS can not turn round normally. By analyzing the fault reasons leading to poor contract, some countermeasures are presented ac cording to the exposed problems.
