Abstract

PURPOSE:To reduce the transportation cost of an insulating oil and eliminate the necessity of a transportation container for an oil-filled electric device by introducing insulating oils in a conservator and a bushing pocket into an auxiliary stay before transportation, and returning it to the original position via high pressure inert gas after transportation. CONSTITUTION:Before transporting the insulating oil to field, a valve 13 is closed, a valve 14 is opened, insulating oils 6 in a conservator 4 and a bushing pocket 5 are filled in upper and lower reinforcing stays 3a, 3b, and the conservator 4 and the bushing pocket 5 are removed. The oil is transported in this state. When reassembling it after transporting it to the field, the conservator 4 and the bushing pocket 5 are mounted, a nitrogen gas bomb 9 is then connected to the valve 13, the valve 14 is opened to press-fit the gas in the bomb into the stays 3a, 3b. As a result, the insulating oil 6 in the stays 3a, 3b is press-fitted into the tank 1, and the insulating oil 6 in the tank 1 is pushed up into the conservator 4 and the bushing pocket 5.
