Abstract

PURPOSE:To reduce the weight of a tank for oil-immersing electric apparatus by a method wherein the elliptical tank for oil-immersing electric apparatus is consisted of two semicircular parts and side plates to joint them, extended parts are provided to the semicircular parts to joint reinforcement plates to this parts and gas rooms are demarcated between the reinforcement plates and the side plates. CONSTITUTION:Semicircular side plates 10 consisting of semicircular parts 1b and extended parts 11 projecting from the both tips are provided confronting with each other to form the elliptical tank for oil-immersing electric apparatus like transformer, reactor, etc. Then flat side plates 1a are arranged locating at the inside of the side plates 10 and selecting the minimum value regions of the circumference directional moment of the side plates 10, and the both ends are jointed respectively to the extended parts 11. After then the respective projecting tips of the side plates 11 and the side plates 1a are connected with the reinforcement plates 16, moreover the tips of the confronting side plates 11 are jointed with each other with the other reinforcement plates 12, and the gaps generated between the plates 12 and the side plates 1a are used as the gas rooms 13. By this way, the maximum generating stress generating by the pressure applied to the tank is reduced sharply, and the use of the tank material having thin thickness is made to be possible.
