摘　　要：通过一起HMB型液压弹簧机构GIS组合电器因油泵异常报警、液压机构无法正常建压、储能失败的故障深入探析,全面介绍采用HMB型液压弹簧机构的GIS基本组成结构、动作原理以及事故现场情况。并设计了一套HMB型液压弹簧机构储能失败的不停电处理措施及验证试验装置,为日后类似典型故障研判提供相关依据。Through an HMB type hydraulic spring mechanism,the GIS combination electrical appliance produced by ABB is analyzed in depth due to abnormal alarm of the oil pump,the hydraulic mechanism cannot build pressure normally,and the failure of energy storage fails.The basic structure,operation principle and accident scene of the GIS using HMB hydraulic spring mechanism are comprehensively introduced,and a set of non-stop power treatment measures and verification experimental devices for energy storage failure of HMB hydraulic spring mechanism are designed,which provides relevant basis for similar typical fault research and judgment in the future.
