Cooling device for transformer and working method thereof

Abstract

The invention discloses a cooling device for a transformer, which relates to the technical field of transformers, and comprises a box body. A vertical plate is fixedly connected to an inner cavity of the box body, and an air inlet groove is formed in the side face of the vertical plate. According to the cooling device for the transformer, the same row of sliding plates are connected through the transverse rods, synchronous movement is guaranteed, the sliding plates move to drive the second through grooves to move, the communication condition of the first through grooves and the air inlet grooves in the corresponding positions can be adjusted by changing the positions of the second through grooves, air enters the box body through different heights, and the multiple air outlet grooves are formed in different positions; the rotating plate is rotated, when the rotating plate rotates, the position of the third through groove is driven to be changed, and when the third through groove is communicated with the air outlet groove, air in the box body is exhausted from the communication position, the air outlet position is changed through rotating the rotating plate, the flowing path of the air in the box body can be changed by changing the air inlet position and the air outlet position, and all air in the box body is ensured to flow, and the cooling effects are guaranteed.

Description

technical field [0001] The 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] A transformer (Transformer) refers to a device that uses the principle of electromagnetic induction to change the AC voltage. During the operation of the transformer, due to the existence of iron loss and copper loss, these losses will be converted into heat energy and radiated outward, which will cause the transformer to heat up continuously and the temperature will rise. Poor heat dissipation of the transformer will cause the temperature of the transformer to rise, exceeding the transformer temperature The allowable level of temperature rise will reduce the service life of the transformer, or damage the transformer. Therefore, in order to ensure good heat dissipation of large transformers, a certain cooling method must be used to take away the heat generated in the transformer. ...
