Vegetable oil transformer with heating function

Abstract

The invention discloses a vegetable oil transformer with a heating function, and the transformer comprises a transformer module which is provided with a first oil inlet interface and a first oil outlet interface; the radiator module is provided with a second oil inlet connector and a second oil outlet connector; the first oil inlet connector is communicated with the second oil outlet connector through the first pipeline; the first oil outlet connector is communicated with the second oil inlet connector through the second pipeline; and the heating module is connected with the first pipeline and the second pipeline, and / or the heating module is connected with the radiator module. The transformer module is connected with the radiator module through a first pipeline and a second pipeline to form a vegetable oil circulation loop, and when the transformer module is put into operation in a cold environment, the heating module heats the first pipeline, the second pipeline and / or the radiator module, so that the temperature of vegetable oil in the transformer module is increased, and the fluidity of the vegetable oil is enhanced; a vegetable oil circulation loop is smooth, and the probability that the transformer module is burnt out due to overheating is reduced.

Description

technical field [0001] The invention relates to the field of air-cooled vegetable oil transformers, in particular to a vegetable oil transformer with a heating function. Background technique [0002] As the concept of global green development continues to ferment, non-polluting, degradable and environmentally friendly vegetable oil transformers are gradually replacing mineral oil transformers. At present, the forced-air-cooled vegetable oil transformer immerses the transformer in a tank storing vegetable oil. After absorbing heat, the vegetable oil is transported to the radiator through an oil pump and pipeline, and the vegetable oil in the radiator is cooled by a fan before being sent back to the tank. In this way, the transformer is circulated to dissipate heat. [0003] Vegetable oils have a pour point of about -10°C. Use vegetable oil transformers in cold environment areas. When put into operation, the vegetable oil is lower than the pour point, which is a state of sol...

AI Technical Summary

Problems solved by technology

Use vegetable oil transformers in cold environment areas. When put into operation, the vegetable oil is lower than the pour point, which is a state of solid-liquid coexistence. If the transformer is directly loaded, the oil circuit is blocked or the flow rate is too slow due to the poor fluidity of the vegetable oil, and the heat cannot be exported in time. , the transformer may be burnt due to local overheating
