Problems solved by technology

[0002]The transformer is an important and indispensable power equipment in the transmission grid, which plays a very important role in regulating the voltage of the grid, so the transformer is an important power Equipment, most of the transformers currently running on the power grid are oil-immersed transformers. Since most oil-immersed transformers use chip radiators, resulting in low heat dissipation efficiency, transformers often have to stop running due to excessive oil temperature rise, otherwise they will It may cause the performance of the transformer to decline, cause the waste of the power grid, and even cause fires and explosions due to the high temperature of the transformer.

Abstract

The invention discloses a radiating device for an oil-immersed transformer. The radiating device comprises an oil-immersed transformer body (1) and a radiating pipe (2), wherein the radiating pipe (2) is arranged in a radiating oil tank of the oil-immersed transformer body (1); one end of the radiating pipe (2) is arranged in the radiating oil tank of the oil-immersed transformer body (1) and the other end of the radiating pipe (2) is arranged on the outer side of the radiating oil tank of the oil-immersed transformer body (1); and radiating liquid is arranged in the radiating pipe (2). Therefore, the running safety of the oil-immersed transformer is improved.

Description

1. Technical field [0001] The invention relates to a cooling device for oil-immersed transformers, in particular to a heat sink suitable for small and medium-sized oil-immersed transformers. 2. Background technology [0002] The transformer is an important and indispensable power equipment in the transmission grid. It plays an important role in regulating the voltage of the grid. Therefore, the transformer is an important power equipment. At present, most of the transformers running on the grid are oil-immersed transformers. , because most of the oil-immersed transformers use chip radiators, resulting in low heat dissipation efficiency, the transformer often has to stop running due to excessive oil temperature rise, otherwise it may cause the performance of the transformer to decline, resulting in waste of the power grid, and even cause the transformer to be damaged due to high oil temperature. If the temperature is too high, it will cause fire, explosion and other phenomena...
