An oil-immersed three-phase transformer

Abstract

The invention discloses an oil-immersed three-phase transformer, which includes a box body, the top of the box body is fixedly connected with a terminal group, and the outer walls of the front and back sides of the box body are fixedly connected with heat dissipation structures. The left end of the body is fixedly connected with an oil tank, and the top of the oil tank is fixedly connected with an oil conservator. Through the special structure of the air guide strip, according to the principle of aerodynamics, when the wind blows, the arc surface of the air guide strip away from the box will flow through the air at a faster speed, while the smooth surface of the air guide strip close to the box will flow through The airflow velocity is relatively slow, forming an air pressure difference, and the air near the box body of the air guide strip rushes toward the side of the arc of the air guide strip, forming a vortex, which accelerates the heat dissipation on the side of the heat sink close to the box body, and the two sides The guide directions of the two windshields are opposite, and the windshields in the opposite direction of the wind guide on both sides can guide the blown wind to the inside of the heat dissipation structure and lead it out from the other end, so that the wind can be guided up and down while forming a vortex, so that The cooling effect is better.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular 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 and is a permanently sealed oil tank. Oil-immersed transformers have been widely used in various power distribution equipment. Oil-immersed The core part of the type three-phase transformer is composed of a closed iron core and a winding on the iron core column. In addition, there are oil tanks, oil storage cabinets, bushings, respirators, explosion-proof pipes, radiators, tap changers, gas relays, thermometers, oil purifiers, etc., but the structure of the traditional oil-immersed three-phase transformer is relatively simple, There are following disadvantages: [0003] 1. Traditional oil-immersed three-phase transformers generally ...
