Description

Technical Field

[0002] The oil-immersed transformer is mainly composed of an iron core, a winding, an oil tank, an oil pillow, an insulating bushing, a tap changer and a gas relay. The iron core and the winding are all immersed in the transformer oil, and the transformer oil plays the role of insulation and cooling. The oil pillow of the transformer is generally above the transformer body, and can continuously supply oil by its own weight. When the existing transformer oil tank structure is used, the transformer is generally embedded in the oil tank for fixing. Most of the fixing methods are fixed by bolts. However, during the installation process, there is no connection limit structure, which makes it difficult to accurately align the mounting holes on the surface of the transformer top plate with the screw holes on the oil tank, and it needs to be assisted during installation. For this reason, we propose a transformer oil tank structure. Utility Model Content

At the same time, at the limit buckle 302, the limit buckle 302 is squeezed by the external force to squeeze the telescopic spring 303 into the interior of the built-in groove 301, and drives the slider 401 to slide in the interior of the slide groove 400 to play a moving guiding role, so that the connecting block 101 and the connecting groove 100 can be fully engaged and connected. At this time, the limit buckle 302 is moved from the inner part of the built-in groove 301 under the action of the telescopic spring 303. After the part is reset and popped out and stuck into the inside of the limiting groove 300, the connecting block 101 can be temporarily limited inside the connecting groove 100, and the positioning hole 500 and the through hole 501 are accurately aligned, and then the positioning screw 502 is used to pass through the inside of the through hole 501 and connect with the positioning hole 500, and finally the positioning screw 502 is tightened to make it screwed and fixedly connected with the positioning hole 500, so that the transformer top plate 3 and the oil tank body 1 can be fixedly connected. When the oil tank body 1 needs to be moved, the lifting ring 601 is first moved to squeeze it apart from the rubber buckle 603, and it is screwed out from the inside of the lifting seat 600 through the connecting shaft 602, and then the crane can be used to connect with the lifting ring 601 to lift the oil tank body 1 for movement.
