PURPOSE:To facilitate a test by fixing a gas tank to the gas-side fitted flange of a bushing to be tested, and inserting bushings to be tested from a side surface of an oil tank after sealing gas and then connecting them to a testing bushing in the oil tank. CONSTITUTION:A testing bushing 16 for oil is fitted by a metallic fixture 17 to the upper part of an oil tank 3, and a conductor 19 for an electric connection with a terminal 22 in the oil in a bushing 1 to be tested is fitted to a terminal 18 in the oil. A gas tank 20 is fitted to a gas-side fitted flange 7 before bushings 1 to be tested are fitted to the oil tank 3, and an gas insulating medium 13 is sealed internally. The bushings 1 to be tested and only inserted into the oil tank 3 to be connected to the connection conductor 19 and then the oil tank 3 is fitted with insulating oil 2, thus completing test preparations. Consequently, a gas connection box is unnecessary and the test preparing operation is performed easily in a short time. |
