Water cooling device for dry type transformer

Abstract

The invention discloses a water cooling device for a dry type transformer, particularly a water cooling device applicable to a dry type transformer, belonging to the technical field of transformer accessories. The invention comprises a casing, a baffle is arranged in the casing and divides the cavity of the casing into a transformer chamber and a water cooling system chamber, a transformer is arranged in the transformer chamber, and a centrifugal fan and a condenser are arranged in the water cooling system chamber. One end of the baffle is provided with an air outlet of the baffle, the air outlet of the baffle is connected with an air inlet of the centrifugal fan, and one end of the baffle connected with the condenser is provided with an air inlet of the baffle. The air outlet of the baffle comprises an air outlet rotating part, an air outlet frame and air outlet vanes, the air outlet rotating part is arranged between two sides of the air outlet frame, and one end of each air outlet vane is connected with the lateral position of the air outlet rotating part. The air inlet of the baffle comprises an air inlet rotating part, an air inlet frame and air inlet vanes, the air inlet rotating part is arranged between two sides of the air inlet frame, and one end of each air inlet vane is connected with the lateral position of the air inlet rotating part. Adopting the structure has the advantages that the operating temperature of the transformer is decreased to a large extent and the operating environment of the product is largely improved.

Description

technical field [0001] The invention belongs to the technical field of transformer accessories, in particular to a water-cooled cooling device suitable for dry-type transformers. Background technique [0002] The transformer will generate a lot of heat during the working process. If the heat cannot be eliminated well, the heat will damage the transformer, shorten the life expectancy of the transformer and even make the transformer unable to work. The conventional air-cooling device of the existing dry-type transformer is to start the axial-flow fan fixed on the channel steel of the transformer foot, and the cold air is discharged from the bottom of the transformer coil through the vertical and horizontal cooling air passages of the coil to discharge the heat during the operation of the transformer to the transformer. On the top, due to the IP20 protection level of the shell, there are cooling holes on the top of the shell. The heat emitted by the transformer is finally tran...

AI Technical Summary

Problems solved by technology

However, the air inlet and air outlet on the baffle plate of the dry-type transformer water cooling device are empty, and there is no opening of any structure in the middle, which causes the wind force of the air inlet and outlet to be scattered, which is not conducive to the flow of air in the transformer room, thus not conducive to Transformer heat dissipation
