Abstract

The embodiment of the invention discloses a transformer cooling device, which includes a transformer box and a support plate fixedly connected to the inner wall of the transformer box. The support plate is equipped with a dust removal and cooling device. Each inner side of the transformer box Zigzag tubes are installed on the walls, and the bottoms of several zigzag tubes communicate with a circulating water tank installed at the bottom of the transformer box. One side of the circulating water tank is connected to a water pump, and one end of the water pump is connected to the The top of the dust removal and cooling device is connected, and the bottom of the side wall of the transformer is provided with a ventilation device; the invention passes air into the cooling water, and uses the water to absorb the dust in the air to achieve the purpose of dust removal, avoiding the accumulation of dust in the air on the surface of the transformer Problems that affect the performance of the transformer, and the temperature of the incoming air is reduced through the cooling water, and the cold air falls into the transformer equipment through the air holes to cool down, and the cooling effect is better.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of transformers, and in particular to a heat dissipation device for a transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. Oil-immersed self-cooling transformer is one of the new types of high-performance transformers. The structure is more reasonable, The performance is better, and it is only used for urban and rural areas, industrial and mining enterprise power grid transformation, combined transformers and transformers for prefabricated substations. [0003] The transformer will generate a lot of heat when it is working, so a cooling device is needed to dissipate the heat generated by the transformer, so that the temperature inside the transformer will not rise to a high level and affect the output capacity and working status of ...
