Abstract

PURPOSE: To previously prevent a ground-fault, by making each control circuit respectively controllable of the on-off switching disconnectors, on condition of an opening of the system switching disconnector and on condition of an opening of the system earth disconnector and the transmission substation system breaker.
CONSTITUTION: The connection is made in series respectively of a contact 46 of the system switching disconnector LS2, 4 to a first control circuit of the system earth disconnector ES1, 3 are a contact 26 of LS1, 2 to a second control circuit of ES2, 5. The interlock condition in the first control circuit of ES1, 3 is constructed in a manner with a trip condition of the LS2, 4 so as to be provided in addition to a trip state of the LS1, 2. And the interlock condition of the second control circuit of the ES2, 5 is made in a manner with a trip state of the LS1, 2 provided in addition to a trip state of the LS2, 4. Accordingly, a ground-fault, caused by an error of the procedure in the equipment handling before the inspection of a transmission substation system breaker CB1, can be previously avoided without limiting an operation of the breaker.
