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.
