Inclined bell jar type oil tank

Abstract

The invention relates to an inclined bell jar type oil tank, which comprises a lower-section oil tank, wherein a lower iron yoke is arranged in the lower-section oil tank. The inclined bell jar type oil tank is characterized in that: an upper-section oil tank is arranged at the top of the lower-section oil tank; a conversion control part is arranged on the lower-section oil tank; an inclined main connection edge is arranged at the top of the lower-section oil tank, and an included angle of 15 to 20 DEG is formed between the inclined main connection edge and a horizontal plane; correspondingly, an inclined auxiliary connection edge is arranged at the bottom of the upper-section oil tank; and the inclined main connection edge and the inclined auxiliary connection edge form a linking strip. Therefore, by relying on the inclined main connection edge which is arranged at the top of the lower-section oil tank, a low-voltage wire connection sheet is not required to be loosened during jar suspension. Work time is saved, and the labor intensity of an operator is reduced. Moreover, because the upper-section oil tank is lower than an ordinary bell jar type oil tank, suspension height is small, requirements for a using space of a user are relatively lower, and great convenience is brought to the user during maintenance and repair of the transformer.

Description

technical field [0001] The invention relates to an oil tank for a transformer, in particular to an inclined bell type oil tank. Background technique [0002] Conventional bell-type oil tank is the most commonly used structural form of large transformers. Its oil tank is composed of upper and lower sections. When the upper section of the oil tank is hoisted, most of the transformer body will be exposed, which will bring great benefits to on-site maintenance. It is very convenient, and its cross-section is mostly oval, rectangular, and octagonal. The height of the lower fuel tank is equivalent to the width of the lower iron yoke. The secondary outgoing line is generally ejected, and the edge of the box is horizontal. The secondary current of large-scale electric furnace transformers and rectifier transformers has tens of thousands of amperes. The secondary side often adopts side outlets. There are many lugs on the low-voltage side connected to low-voltage conductive bars or ...

AI Technical Summary

Problems solved by technology

The secondary current of large-scale electric furnace transformers and rectifier transformers has tens of thousands of amperes. The secondary side often adopts side outlets. There are many lugs on the low-voltage side connected to low-voltage conductive bars or water-cooled conductive rods. They are installed through the installation hand holes. Ordinary bell-type oil tank cranes When covering, the lugs must be loosened completely, which is difficult to operate, labor-intensive, and wastes man-hours, and repeated tightening will produce metal chips, which is difficult to clean
