| Abstract: | The failure Reason of electrical blocking circuit of disconnector under special situation found in the debug process of 220kV Hengxian substation are analyzed.It is pointed out that the electrical blocking logic under special situation should be verified in the debug process to avoid important potential security risk.The scheme that the design circuit should be modified to avoid the special situation above is proposed. |
