Damp-proof heat dissipation power transformation cabinet

Abstract

A damp-proof heat dissipation power transformation cabinet disclosed by the present invention comprises a cabinet body, the inner wall of the cabinet body is fixedly connected with a transverse plate, the transverse plate divides the cabinet body into a mounting box and a cooling cavity, a dehumidification groove is formed in the upper end of the mounting box in a penetrating manner, and a dustproof net is mounted in the dehumidification groove. A sealing plate which abuts against the dehumidification groove and has a guiding function is slidably connected to the inner top of the mounting box, a temperature driving mechanism is arranged between the sealing plate and the mounting box, a draught fan is mounted on the transverse plate, a heat exchange pipe is arranged in the cooling cavity and connected with the air inlet end of the draught fan through a short pipe, and the air inlet end of the draught fan is connected with the air inlet end of the draught fan. And the other end of the heat exchange pipe is fixedly connected with a conveying pipe, and a connecting pipe communicating with the mounting box is arranged at the upper end of the mounting box in a penetrating mode. The dehumidification and damp-proof effects on the electrical equipment can be achieved, the heat dissipation effect on the electrical equipment in the cabinet body is good, meanwhile, dust in external air cannot fall on the electrical equipment, and heat dissipation of the electrical equipment cannot be affected.

Description

technical field [0001] The invention relates to the technical field of transformer cabinets, in particular to a moisture-proof and heat-dissipating transformer cabinet. Background technique [0002] A transformer cabinet is an electrical device that converts high voltage to low voltage or low voltage to high voltage. The use of variable voltage transmission in power plants means that the electric energy generated by power generation is converted into high voltage for transmission to reduce the loss in the transmission process, and then the high voltage is converted into low voltage for use by users. [0003] The long-term continuous operation of the electrical components inside the transformer cabinet will lead to heat accumulation. The long-term heat accumulation will affect the electrical components in the transformer cabinet. In severe cases, it may cause short-circuit of the internal electrical components; As a result, the power consumption of residents in some areas or...

AI Technical Summary

Problems solved by technology

[0005] 1. The heat dissipation effect of the electrical equipment in the substation cabinet through the cooling holes or windows is insufficient, especially in summer, or the substation cabinet is in a relatively warm environment, which may still cause a short circuit of the internal electrical components;

[0006] 2. The electrical equipment in the substation cabinet is dissipated through heat dissipation holes or windows. At the same time, it also causes dust in the external air to enter the substation cabinet, causing the dust to fall on the electrical equipment and affecting the heat dissipation of the electrical equipment;
