Cooling device special for transformer

Abstract

The invention discloses a cooling device special for a transformer. The cooling device special for the transformer comprises a negative-pressure fan, an air distributing manifold and an exhaust fan, wherein the negative-pressure fan and the exhaust fan are mounted on the housing of the transformer; the negative-pressure fan is connected with an air inlet pipe which is connected to the air inlet end of the air distributing manifold; the exhaust fan is connected with an air outlet pipe with one end extends into the housing of the transformer; the air distributing manifold is laid on the inner surface of the housing of the transformer and provided with a plurality of blowing pipes; every blowing pipe is composed of an inner pipe, an outer pipe and a disc, wherein the disc is arranged on the inner pipe in a sleeve mode, the outer pipe covers the inner pipe, the outer pipe is welded to the disc, and the side surface of the outer pipe is provided with a blowing outlet. The cooling device special for the transformer is mounted inside the transformer, and can greatly improve the cooling efficiency of the transformer and avoid damage of the transformer due to lack of timely cooling.

Description

technical field [0001] The invention relates to a transformer, in particular to a cooling device for the transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and 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.). [0003] When the transformer is working, it will generate a lot of heat. If the heat ...
