摘要
通过一起发电机出口开关液压弹簧操作机构储能失去的应急处理及故障原因分析,验证了应急处理措施的正确性,找出了开关分闸电磁阀未关闭到位是引起本次故障的主要原因,并提出了相应的措施建议,为此类型设备的运维和故障处理提供参考。
Through the emergency treatment and fault cause analysis on the energy storage failure of the hydraulic spring operating mechanism of the generator outlet switch,the correctness of the emergency treatment measures is verified.The main cause of the fault is found that the switch opening solenoid valve is not closed in place,and the corresponding measures and suggestions are put forward,which provides a certain reference for the operation and maintenance and fault treatment of this type of equipment.
