Abstract

The invention provides a power transformation cabinet dust-settling device, and relates to the field of electrical equipment of an electric power system. The problems that dust in an outdoor power transformation cabinet is large, and an existing dust removal mode is low in efficiency are solved. A supporting shaft is used for being fixed in a power transformation cabinet. A paper tube is sleeved outside the supporting shaft and can rotate. The electrostatic adsorption paper is long-strip-shaped, the head end of the electrostatic adsorption paper is fixedly connected with the outer surface of the paper tube and wound on the outer surface of the paper tube in a stacked mode to form a paper roll structure, the driving roller is located under the paper tube, the tail end of the electrostatic adsorption paper is fixedly connected with the outer surface of the driving roller, and one end of the driving roller extends out of a rotating handle in the axial direction. The power transformation cabinet dust-settling device is suitable for an electric cabinet working in an outdoor area with large dust.

Description

technical field [0001] The invention belongs to the field of electrical equipment in a power system, and in particular relates to a dust reduction technology for a transformer cabinet. Background technique [0002] In power plants, variable voltage transmission is generally used to convert the generated electric energy into high voltage for transmission to reduce losses. Then the high voltage is converted into low voltage and delivered to the user. Therefore, it is necessary to use a transformer cabinet to centrally transform the voltage. Transformer cabinet is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme, which organically combines functions such as transformer step-down and low-voltage power distribution. [0003] In urban areas, most transformer cabinets are located outdoors, and a large amount of dust often enters the cabinet. A large amount of dust accumulation will seriously affect the ...
