Transformer self-cooling type high-frequency power supply for electric dust remover

Abstract

The invention provides a transformer self-cooling type high-frequency power supply for an electric dust remover. The power supply comprises a cabinet body, a transformer, a centrifugal fan, and a circuit breaker device, a contactor, a controller, a pre-charging device and a high-frequency power supply inversion part device which are arranged in the cabinet body; the cabinet body is composed of a plurality of small cabinet body units, and comprises a main cabinet body, a left cabinet body arranged in the left part of the main cabinet body, and a right upper cabinet body and a right lower cabinet body in the right part of the main cabinet body; a transformer is installed at the rear part of the cabinet body, a high-frequency power supply inversion part device is placed in the main cabinet body, and a circuit breaker, a contactor and a pre-charging device are placed in the left cabinet body, a power supply controller and a wiring terminal are arranged in the right side upper cabinet body, and a centrifugal fan is arranged in the right lower cabinet body. The high-frequency power supply is simple in overall structure, convenient to install, carry and maintain, and capable of improving the heat dissipation efficiency and the stability of a heat dissipation system.

Description

【Technical field】 [0001] The invention relates to the technical field of electric precipitator accessories, in particular to a high-frequency power supply for a transformer self-cooling electric precipitator. 【Background technique】 [0002] The high-frequency power supply in the existing dust collector power supply market has basically been finalized into several types after a long period of development, including forced air-cooled high-frequency power supply and liquid-cooled high-frequency power supply. Forced air-cooled high-frequency power supplies are more common, and high-power fans are used to dissipate heat from main heating devices and high-frequency transformers. The liquid-cooled type uses transformer insulating oil or coolant, combined with heat exchange methods such as cooling water tanks, to realize power dissipation. [0003] At present, there are still some problems in high-frequency switching power supply products: [0004] Air-cooled high-frequency power ...

AI Technical Summary

Problems solved by technology

[0004] Air-cooled high-frequency power supply, due to the existence of high-power fans and large-volume air ducts of transformers, makes the structure of the power supply complex, and it is difficult to reduce the volume. At the same time, due to the large air volume, it is difficult to improve the protection level, and frequent problems of dust accumulation and moisture inside the power supply

[0005] The liquid-cooled high-frequency power supply adds components such as liquid passages, heat exchangers, liquid circulation pumps, and various valves, resulting in complex structures and many failure points

Difficult to repair if liquid leaks

If the oil cooling method is used, it is easy to cause the transformer insulating oil to deteriorate, reduce the insulation and heat dissipation performance, and reduce the service life of the transformer
