A cooling device for a transformer and its working method

Abstract

The invention discloses a cooling device for a transformer, which comprises a box body. A vertical plate is fixedly connected to the inner cavity of the box body, and an air intake slot is opened on the side of the vertical plate. The invention relates to the technical field of transformers. The transformer uses a cooling device, and the same row of slides is connected by a cross bar to ensure synchronous movement. The movement of the slides drives the second slot to move. By changing the position of the second slot, the corresponding position of the first slot and the intake air can be adjusted. The connection of the grooves, the air enters the box through different heights, and multiple air outlet grooves are set at different positions. When the rotating plate rotates, the position of the third through groove is driven to change when the rotating plate rotates. When the third through groove and the air outlet groove are connected , the air in the box is discharged from the connecting position. By rotating the rotating plate, the air outlet position can be changed. By changing the air intake position and the air outlet position, the air flow path in the box can be changed to ensure that all the air in the box will flow and ensure the cooling effect.

Description

A cooling device for transformer and its working method technical field [0001] The present invention relates to the technical field of transformers, in particular to a cooling device for a transformer and a working method thereof. Background technique [0002] Transformer refers to a device that uses the principle of electromagnetic induction to change AC voltage. transformer During operation, due to the existence of iron loss and copper loss, these losses will be converted into heat energy and radiated outward, causing The transformer continues to heat up and the temperature rises, and the heat dissipation of the transformer is not good, which will cause the temperature of the transformer to rise, exceeding the allowable limit of the transformer. The temperature rise level will reduce the service life of the transformer in light, and damage the transformer in severe cases. Therefore, in order to ensure the heat dissipation of large transformers Good, some cooling met...
