Transformer oil tank with easiness of cooling and radiating

Abstract

The invention discloses a transformer oil tank with easiness of cooling and radiating, which comprises a base and an oil tank main body; the oil tank main body is located on the base, and the oil tank main body is a cylinder with a wide upper part and a narrow lower part; multiple reinforcing ribs are integrally shaped on the side wall of the oil tank main body, the top part and the bottom part of the oil tank main body are provided with a top groove and a bottom groove; the top part of the oil tank main body is provided with a cooling cavity with the same shape as the top groove, the lower part of the bottom groove is provided with a fixing plate, and the fixing plate is fixed on the base through a bolt; the top groove is in the shape of arc, and the bottom groove is in the shape of reversed arc. Through a structure for facilitating oil flow, the transformer oil tank can enhance the mobility of cold and hot oil, increase the cooling effect, strengthen the integrated shaping of the ribs, greatly improve the mechanical strength of the oil tank, reduce the welding volume, enlarge the radiating area of the main body, and improve the radiating effect; moreover, the reinforcing ribs can disperse sound wave and further reduce noise.

Description

Technical field: [0001] The invention belongs to the field of transformers, in particular to a transformer oil tank that is easy to cool and dissipate heat. Background technique: [0002] As we all know, transformers are widely used in production. Transformers are devices that use the principle of electromagnetic induction to change AC voltage. The oil tank is an important part of the transformer. The oil in the existing oil tank has poor fluidity and poor cooling effect. [0003] As we all know, the transformer coils of oil-immersed transformers used for power distribution in urban power grids are stored in oil tanks and cooled by oil. In order to ensure the safety and heat dissipation in the oil tanks, the oil tanks of existing oil-immersed transformers are often equipped with structural reinforcement , reinforcement plates, and heat dissipation structures other than heat sinks, but such additional structures are generally welded, and the mechanical strength of the fuel ta...

[0002] As we all know, transformers are widely used in production. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The oil tank is an important part of the transformer. The oil in the existing oil tank has poor fluidity and poor cooling effect.

[0003] As we all know, the transformer coils of oil-immersed transformers used for power distribution in urban power grids are stored in oil tanks and cooled by oil. In order to ensure the safety and heat dissipation in the oil tanks, the oil tanks of existing oil-immersed transformers are often equipped with structural reinforcement , reinforcement plates, and heat dissipation structures other than heat sinks, but such additional structures are generally welded, because the welds have an impact on the mechanical strength of the fuel tank itself, and the processing is cumbersome
