Oil-immersed transformer
专利汇可以提供Oil-immersed transformer专利检索，专利查询，专利分析的服务。并且PURPOSE:To easily and economically manufacture a bellows and also improve the quality of transformer by providing a bellows in the middle way of oil duct arranged with an inclination and attached to the inclined portion formed at the upper side end of tank which accommodates the interior of transformer. CONSTITUTION:The interior of transformer consisting of an iron core 1 and windings is accommodated within a tank 3 with insulation oil 4. The inclined portion 3a is formed at both side ends at the upper part of tank 3 in order to satisfy reduction in amount of oil and limit of transportion size. Then tank 3 is surrounded by a sound-proof wall 5. The lead 6 extended from the body of oil immersed transformer passes in 3-phase through an oil duct 7 arranged with inclination and provided to the inclined portion 3a of tank 3, fixed at the end of oil duct 7 and is connected in 3-phase at a time to a oil-gas bushing 9 accommodated within the bushing oil duct 8 arranged horizontally. A bellows 11 is provided in the middle way of oil duct 7 arranged with inclination.，下面是Oil-immersed transformer专利的具体信息内容。
