Oil-immersed three-phase transformer

Abstract

The invention discloses an oil-immersed three-phase transformer which comprises a box body; a wiring terminal set is fixedly connected to the top of the box body, heat dissipation structures are fixedly connected to the outer walls of the front side and the back side of the box body, an oil tank is fixedly connected to the left end of the box body, and an oil conservator is fixedly connected to the top of the oil tank. Through the special structure of the air guide strips, when wind blows through the air guide strips according to the aerodynamic principle, the speed of airflow flowing throughthe cambered surfaces, away from the box body, of the air guide strips is higher, whereas the speed of airflow flowing through the smooth surfaces, close to the box body, of the air guide strips is relatively lower, and thereby an air pressure difference is formed; then the air, close to the box body, of the air guide strip rushes towards one side of the arc position of the air guide strip to forma vortex, heat dissipation of the side, close to the box body, of the cooling fin is accelerated, the flow guide directions of the two air blocking pieces are opposite, and the air blocking pieces onthe two sides can guide blown air into the heat dissipation structure in the opposite air guide directions and guide the air out of the other end. Therefore, the air can be guided vertically while vortexes are formed, so that the heat dissipation effect is better.

Description

Technical field[0001]The invention belongs to the technical field of transformers, and specifically relates to an oil-immersed three-phase transformer.Background technique[0002]The oil-immersed three-phase transformer adopts a fully oil-filled sealed corrugated oil tank shell, which adapts to the expansion of oil with its own elasticity. It is a permanently sealed oil tank. The oil-immersed transformer has been widely used in various power distribution equipment. The core part of the three-phase transformer is composed of a closed iron core and a winding sheathed on the iron core column. In addition, there are oil tanks, oil conservators, bushings, breathing apparatus, explosion-proof tubes, radiators, tap switches, Buchholz relays, thermometers, oil purifiers, etc., but the structure of traditional oil-immersed three-phase transformers is relatively simple. There are the following disadvantages:[0003]1. The traditional oil-immersed three-phase transformer generally measures the tem...
