Abstract
PURPOSE:To cut off ground fault points from other sound parts in earlier time without failing to miniaturize by insulating a common container from ground and placing together with the insulation of a connecting section with a bus side disconnecting switch and providing a current detection method to an earth wire between the common container and ground. CONSTITUTION:A common container 17 is insulated from ground by insulation plates 34 and 35 between the lower part of a mechanism case 27 and a holder 36, and is grounded through a ground terminal 37 provided to a bottom plated 26 and an earth wire 38. A current detection means 39 is placed to the earth wire. Insulation spacers 7 and 8 are placed between the common container 17 and bus side disconnecting switches 2 and 5. Ground faults occurred between a cable head 18 and bus side disconnecting switches 2 and 5, in other words, the ground faults generated at the inside of the common container 17 is such that the ground current flows through the earth wire 38 and is detected by the current detection means 39. Accordingly, said braker is tripped, and operation can be continued by opening the bus side disconnecting switches 2 and 5 only.
