Heat dissipation shell of transformer

Abstract

The invention discloses a heat dissipation shell of a transformer. The heat dissipation shell comprises a main shell, wherein a base is arranged in the main shell; the transformer is fixedly connectedto the upper side of the base; a first copper plate is fixedly connected to the front surface of the transformer; first heat dissipation aluminum sheets are welded to the first copper plate, whereinthe number of the first heat dissipation aluminum sheets is three; a second copper plate is arranged on the upper side of the transformer; and second heat dissipation aluminum sheets are welded to theupper side of the second copper plate. A part of heat generated in the working process of the transformer is subjected to heat dissipation through the second copper plate fixedly connected with the transformer; the second heat dissipation aluminum sheets are arranged on the upper part of the second copper plate, and the upper parts of the second heat dissipation aluminum sheets penetrate throughthe upper shell of the main shell, so that the upper part of the main shell is located outside the main shell, and the heat dissipation effect is better; and in addition, the main shell is in a fully-closed form, so that dust entering in the main shell is prevented, so that generation of a short circuit in the main shell due to dust entering is prevented.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of transformers, in particular to a heat dissipation casing of a transformer. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.), the heat dissipatio...

AI Technical Summary

Problems solved by technology

[0003] The transformer is a complete set of voltage transformation equipment, which can be used for terminal power supply and ring network power supply. The conversion is very convenient and ensures the reliability and flexibility of power supply. However, the transformer will generate a lot of heat during operation. The traditional transformer heat dissipation is mainly By setting air ducts or oil ducts in the body, the heat is taken away by the circulating flow of gas or oil for heat dissipation, which is difficult to maintain and prone to dust, and is highly specific to the type of transformer and does not have universal applicability. The traditional There is also a heat sink for heat dissipation, but the heat sink is usually set inside and dissipates the heat through the ventilation holes, but the heat dissipation efficiency is not high

[0004] The traditional transformer cooling case has the following disadvantages: 1. It is easy to generate dust inside. 2. The heat sink is set inside the main casing, and the heat dissipation efficiency is low. Therefore, we introduce a transformer cooling case
