Abstract

The invention discloses an oil-immersed transformer easy to assemble and overhaul. A guide sliding assembly is arranged between a transformer body and an oil tank bottom shell, the guide sliding assembly comprises two guide columns and a guide groove piece, and the two guide columns are vertically arranged in parallel; the top and the bottom of the guide column are fixedly connected to the two ends of an upper clamping piece and the two ends of a lower clamping piece of the transformer body. The two guide groove pieces are vertically arranged in parallel and fixedly connected to the inner sideof the side wall of the oil tank bottom shell. The guide column can be connected into a groove opening of the guide groove piece in a guiding and sliding mode. According to the oil-immersed transformer easy to assemble and overhaul, the guide sliding assembly is arranged between the transformer body and the oil tank bottom shell, it can be guaranteed that the hoisting process is smooth, collisionand scratching are avoided, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oil-immersed transformers, in particular to an oil-immersed transformer that is easy to assemble and repair. Background technique [0002] The body of the oil-immersed transformer, including windings and iron cores, is installed in an oil tank filled with transformer oil, and the oil tank is welded with steel plates. The oil tank of medium and small transformers is composed of a tank shell and a tank cover. The body of the transformer is placed in the tank shell, and the tank cover can be lifted out for maintenance. [0003] When the existing oil-immersed transformer is assembled or overhauled, the body and the tank cover can be hoisted as a whole to enter or exit the bottom shell of the oil tank. There is a lower positioning structure between the body and the bottom shell. The traditional lower positioning structure is to weld a threaded positioning nail on the bottom of the fuel tank, and open a hole o...
