Miniaturized 1.2A electric-precipitation high-frequency high-voltage power supply

Abstract

The invention relates to a miniaturized 1.2A electric-precipitation high-frequency high-voltage power supply. The power supply comprises a cabinet and an oil tank which are arranged in an up-down direction; an external junction box, an air inlet cover and an air outlet cover are arranged on the side surface of the cabinet, and the air inlet cover and the air outlet cover penetrate through the sidewall of the cabinet; a main control circuit assembly and a power circuit assembly which are arranged in an up-down layered mode are installed in the cabinet, and the main control circuit assembly iselectrically connected with the power circuit assembly. A transformer and a high-voltage silicon stack are installed in the oil tank, the secondary side of the transformer is electrically connected with the high-voltage silicon stack, and the primary side of the transformer is connected with the power circuit assembly. A horn-shaped high-voltage cover is installed at the outer side of the oil tank, a wide opening of the high-voltage cover faces outwards, a high-voltage output binding post is installed in the center of the high-voltage cover, and the high-voltage output binding post passes through the wall of the oil tank to be connected with the high-voltage silicon stack. The power supply is compact in structure, smaller in size, good in heat dissipation performance, higher in IP protection level and easy to install and maintain.

Description

technical field [0001] The invention relates to the field of high-frequency and high-voltage power supplies, in particular to a miniaturized 1.2A high-frequency and high-voltage power supply for electric dust removal. Background technique [0002] At present, the high-frequency dust removal power supplies on the market generally have the following problems: large size, high transformer cost, low IP protection level for outdoor applications, poor heat dissipation performance, poor power supply reliability, and difficult installation and maintenance. The main reasons are: the large eddy current loss of the transformer, the unreasonable heat dissipation design of the main power circuit, the serious high-frequency skin effect, and the conflict between the IP protection level of the cabinet and the system heat dissipation. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present invention provides a miniaturized 1.2A electric du...
