Oil-immersed transformer and heat dissipation system thereof

Abstract

The invention discloses an oil-immersed transformer and a heat dissipation system thereof. The oil-immersed transformer includes a base. Wheel grooves are disposed at the four corners of the bottom ofthe base. Moving wheels are arranged in the wheel grooves. The bottom of each moving wheel extends through the corresponding wheel groove to the outside of the wheel groove. The two sides of the topof the inner wall of each wheel groove are fixedly connected with fixed insert rods. The surface of each fixed insert rod is sleeved with an insert sleeve. A side of each insert sleeve close to the moving wheel is fixedly connected with the moving wheel. Mounting brackets are fixedly connected to both sides of the bottom of the base. Fixing blocks are fixedly connected to both sides of the top ofthe base. Suspension rings are fixed to the tops of the fixing blocks. Sliding grooves are disposed on the two opposite sides of the two fixing blocks. The oil-immersed transformer is simple in structure, integrates transportation and installation processes, is improved in convenience and safety during transportation, reduces installation steps of workers, is improved in installation efficiency, convenient to use and popularize. The heat dissipation system can accurately control the temperature of the transformer and has a good heat dissipation effect, can avoid the transformer being in full-load state.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an oil-immersed transformer and a cooling system thereof. 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 purpose, 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] The oil-immersed transformers in...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an oil-immersed transformer and its heat dissipation system, which has the advantages of convenient transportation, solves the problem that oil-immersed transformers in the prior art are often inconvenient to transport, and has a heat dissipation function, and its heat dissipation system can be accurately Control the temperature of the transformer, and the heat dissipation effect is good, which can reduce the temperature of the transformer when it is in full-load operation.
