A box-type transformer and its manufacturing method

Abstract

The invention relates to a box-type transformer and a preparation method thereof. The box-type transformer includes a first box body and a second box body arranged up and down, the first box body accommodates a high-voltage room, a low-voltage room and a control room inside, the second box body is arranged in the pit, and A transformer is accommodated inside the second box, and a first space exists between the second box and the transformer; a second space exists between the second box and the pit; the second The top cover of the box body has an arched structure; the periphery of the bottom wall of the second box body is evenly distributed with through holes; the top cover and the inner surfaces of the side walls of the second box body are coated with a first coating; The inner surface of the side wall of the pit is coated with a second coating. The heat generated by the underground transformer of the box-type transformer of the present invention can be quickly and effectively dissipated, and it is not easy to be affected by moisture and enter water, thereby improving the safety degree and service life of the box-type transformer.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a box-type transformer and a manufacturing method thereof. Background technique [0002] The box-type transformer is a compact and complete set of power distribution devices that combine high-voltage electrical equipment, transformers, and low-voltage electrical equipment to receive and distribute electrical energy in the power distribution system. The basic principle of box-type transformers is that through the pressure start system, armored line, fully automatic system of substation, DC point and corresponding technical equipment, reasonable assembly is carried out in the prescribed order, and all components are installed in a specific waterproof and dustproof. A specific transformer is formed in a completely sealed tempered box structure such as rodent proof. [0003] At present, box-type transformers have been widely used in power engineering construction. Because the box-type t...

Problems solved by technology

Due to the weather, rainwater is often deposited in the pit. In the weather environment of high temperature or sunlight, a large amount of condensation is easy to be generated on the lower part of the box-type transformer box, which makes the equipment inside the box damp and causes accidents such as short circuit.
