摘　　要：隔离开关作为电网的主设备,其可靠动作直接关系到电力系统稳定运行。介绍一起隔离开关运行时出现的两级减速机构脱离故障,通过运行监测和受力分析确认了故障产生的原因,并针对性地提出了减速机构的改进方案,最后通过拉伸实验和动作测试验证了方案的有效性,为隔离开关减速机构的制造改进提供参考。As the main equipment of the power grid,the reliable operation of the disconnector is directly related to the stable operation of the power system.A two-stage reducing mechanism break-off fault of the disconnector is introduced.Causes of the failure are analyzed by working monitoring and force analysis.Improvement programs of the reducing mechanism are proposed,and the effectiveness of the scheme is verified by the tensileaction test,which provides references for the improvement of reducing mechanism manufacturing.
