摘要： PROBLEM TO BE SOLVED: To detect the grounding accident on the side of high-voltage distribution cable, with the circuit on low voltage side of a transformer for power reception, by detecting the reverse-phase components of the fundamental wave of a three-phase AC current detected with a three-phase AC detector, and judging the existence of the occurrence of the grounding accident from this reverse-phase components. SOLUTION: When it is judged that a grounding accident has occurred in any of high-voltage distribution cables 3a-3c by grounding judgers provided at network protectors 4Ga-4Gc, breaker controller 4Ea-4Ec give breakers 4Da-4Dc breaking commands. For example, when the high-voltage distribution cable 3a is cut off the bus 1B1 of a substation 1, the protector breaker 4Da opens to cut off the circuit on high voltage side and the circuit on low voltage side of the transformer 4Ba from each other because the grounding judger of the breaker controller 4Ea detects a grounding accident occurring in the high-voltage cable 3a. As a result, this system can prevent the tidal current of reverse power from occurring on the side of high-voltage distribution cable 3a from side of other sound distribution cables 3a and 3c.

摘要： PROBLEM TO BE SOLVED: To prevent the temperature of a packing provided to a connection part between a transformer tank of a ground installation type transformer device and a primary side switchgear (LBS), from rising to be degraded in an early stage.SOLUTION: A bushing fitting part 201b2 provided to a switch case 201 of the LBS is connected to a side wall 6b1 of a transformer tank 6 with a packing 16 in between. Primary bushing terminals 14u-14w fitted to the bushing fitting part are guided into the transformer tank 6 by way of a bushing guiding-in window part 6h provided to the side wall 6b1. A heat insulating plate 21 that covers the peripheral part of the window part 6h is arranged inside the transformer tank 6, to suppress rising of temperature of the packing 16. A portion of an oil penetration part of the primary bushing terminals 14u-14w which is closer to the LBS is taken as an isolation object part 14B1. A bushing terminal isolation part 25 is provided to isolate the isolation object part from the convection of insulating oil 7 that occurs in the transformer tank.
