Abstract

The invention relates to a transformer. The transformer comprises an oil tank which is provided with an oil inlet channel and an oil outlet; the cooling system comprises a finned radiator, an outlet of the finned radiator is communicated with the oil inlet channel, and an inlet of the finned radiator is communicated with the oil outlet, so that a cooling loop allowing a cooling medium to circulate is formed; wherein the finned radiator comprises a plurality of finned radiators, and each finned radiator is constructed to be formed by splicing a plurality of hollow cylinders. According to the transformer, the cooling system comprises a finned radiator, the finned radiator comprises a plurality of finned radiators, and each finned radiator is constructed to be formed by splicing a plurality of hollow cylinders. On one hand, the sheet radiator formed by the plurality of hollow cylinder structures can increase the perimeter to the greatest extent on the same length so as to enlarge the radiating surface; on the other hand, the oil flow resistance of transformer oil can be reduced. The heat dissipation capability of the whole transformer can be improved by increasing the heat dissipation surface and reducing the oil flow resistance, so that the normal operation of the transformer is ensured.

Description

technical field [0001] The present application relates to the technical field of transformer cooling, in particular to a cooler. Background technique [0002] With the enhancement of domestic environmental protection and transformer fire protection or explosion-proof safety awareness, the application of vegetable insulating oil transformers has developed rapidly. As a new type of environmentally friendly liquid insulating material, vegetable insulating oil, compared with traditional mineral oil, in terms of fire prevention, especially explosion-proof safety, because its ignition point is higher than 300 ° C, it is not easy to burn, and its fire safety performance is outstanding. It belongs to K class Flame-retardant insulating materials; in terms of environmental protection, its degradability is one of its main advantages. The biodegradation rate of vegetable insulating oil can reach 97% in 28 days. If an accident occurs, it will not cause environmental pollution to the atmo...
