PURPOSE:To improve the performance of insulation protection and maintenance by mounting a flange to a bushing pocket and detachably connecting a flange for an arrester vessel housing an arrester unit to the flange. CONSTITUTION:An arrester vessel 8 housing an arrester unit 7 and a bushing pocket 4a from which a bushing 5 is erected are connected detachably by a flange 8a mounted to the arrester vessel 8 and a flange 4b fitted to the bushing pocket 4a. The arrester vessel 8 is supported to the upper surface of an oil tank 2 through a connecting fitting 9. Consequently, the arrester vessel 8 housing the arrester unit 7 is connected and supported to the bushing pocket 4a and the upper surface of the oil tank 2 through the flanges 8a, 4b and the connecting fitting 9, thus easily assembling an electrical apparatus in which the arrester unit 7 is fitted for insulation protection, then improving maintenance. Since the arrester unit 7 is mounted into the arrester vessel 8, an effect due to an accident by the arrester unit 7 is reduced, and the performance of insulation protection can be enhanced. |
