Transformer oil tank structure

Abstract

The invention relates to a transformer oil tank structure comprising a tank body and tank edges, the tank body is rectangular and comprises an opening at the top part, the longitudinal section of the tank edges is shaped like a rectangular 7, the bottom surface of the vertical side of the 7 is fixedly welded with the opening end surface of a tank body wall of the tank body, and the four tank edges are mutually connected to constitute a whole body with the tank body. The transformer oil tank structure is characterized in that two ends of the tank edges which are oppositely arranged are respectively longer than the tank body wall, and the vertical sides of the tank edges which are longer than the tank body wall are respectively provided with a through hole. Compared with the prior art, the transformer oil tank structure utilizes the originally arranged tank edges to extend the tank edges which are oppositely arranged backward, one through hole is respectively arranged on the vertical side of each extension part for being used as a hanging hole, as the tank edges and the tank body wall are integrally and fixedly welded, the welding surface is large and the integrity is good, thereby not only eliminating the shortcoming that the prior art needs to fixedly weld the hanging rings separately, but also improving the reliability of the hanging rings.

Description

【Technical field】 [0001] The utility model belongs to an oil-immersed distribution transformer, in particular to an oil tank structure of an oil-immersed distribution transformer. 【Background technique】 [0002] Before the utility model was made, the oil tank structure of the oil-immersed distribution transformer included a box body and a box cover. In order to ensure the sealed connection between the box body and the box cover, four box edges were fixedly welded on the port of the box body. The box edge is actually four angle steels with the same length as the rectangular box wall. The thickness direction of the angle steel and the thickness direction of the box body wall are butt-welded together, and then, the horizontal surface of the angle steel is used to realize the connection with the box cover through fasteners. Therefore, the edge of the box plays the role of the flange of the box. In order to adapt to the lifting of the oil tank, four lifting rings are fixedly wel...

Problems solved by technology

The production of this kind of oil tank structure is not only time-consuming and complex in process, but also poor in integrity and unsightly, especially the reliability of the hoisting product is poor, and when the hoisting ring is damaged, due to the existence of transformer oil, repeated welding cannot be carried out, which will bring harm to the hoisting of the product. It increases the difficulty of product repair
