Oil tank for oil immersion type transformer

Abstract

The invention relates to an oil tank for an oil immersion type transformer, which is used for lowering noise of the oil immersion type transformer and comprises an oil tank body. A layer of tank wall structure is arranged at the outer side of the oil tank body, and a preset air gap is arranged between the tank wall structure and the oil tank body. Flame-retardant and sound-absorbing materials] are lined in the air gap. The tank wall structure and the oil tank body are fixedly connected with a radiator pipe of the oil immersion type transformer in an electric welding way. The invention achieves the effect of noise reduction by improving the structure of the oil tank, has simple structure, convenient processing, favorable concealment and favorable practicability, and can efficiently reduce the noise generated in operation of the transformer, thereby the noise pollution brought by the environment is improved.

Description

technical field [0001] The invention relates to a transformer, in particular to an oil-immersed transformer oil tank. Background technique [0002] Existing transformers have certain noise during operation, especially when the load is relatively large, the noise emitted by the transformer is particularly obvious. Parameters such as structure, core steel sheet quality, and manufacturing process all affect the magnetic expansion and contraction of the transformer. Even if the above parameters meet the standards, the transformer noise still cannot be eliminated. [0003] In order to reduce noise, the existing solution is to add various sound-absorbing and sound-insulating materials around the fuel tank, or to build another sound-proof room to reduce noise. However, installing sound-absorbing or sound-insulating materials outside the transformer oil tank takes up a lot of space, makes it difficult to fix and support, and greatly affects the heat dissipation performance of the o...

AI Technical Summary

Problems solved by technology

However, installing sound-absorbing or sound-insulating materials outside the transformer oil tank takes up significantly more space, making it difficult to fix and support, and greatly affecting the heat dissipation performance of the oil tank.

If a special soundproof room is built and equipped with ventilation and heat dissipation facilities, the noise reduction effect will be significantly improved, but the cost is too high and the cost performance is not ideal.
