摘　　要：分析当前110 kV及以上电压等级间隔热倒母线操作流程,对比GIS间隔就地控制屏远方/就地切换把手接线方式,对切换过程中引发的报警原因进行诊断,探讨“断路器控制回路断线”信号引发的主要风险点,并提出改进方案以降低热倒母线风险。Analysis is carried out on the current thermal insulation inverted bus operation process between 110 kV and above voltage levels,the remote/local switch handle connection modes of the local control display panel are compared,the alarm causes due to the switching operations are diagnosed,and the main risk points caused by the signal"breaker control circuit disconnection"are discussed,based on which an improvement and optimization plan is put forward to reduce the risks of hot inverted bus.
