Waterproof and dustproof electrical cabinet

Abstract

The invention discloses a waterproof and dustproof electrical cabinet. The electrical cabinet comprises a cabinet body, a thermal insulation plate arranged on the outer side of the cabinet body, a separation plate arranged in the cabinet body, a thermal insulation door plate arranged in front of the cabinet body, a heat radiator arranged on the side face of the cabinet body, a ventilation hole arranged in the side face of the cabinet body, a temperature sensor arranged on the separation plate and a temperature display arranged on the outer side of the door plate. The thermal insulation door plate comprises an inner side plate and an outer side plate. A gap is arranged and an enclosed space is formed between the inner side plate and the outer side plate. A first ventilation opening is arranged in the inner side plate and a second ventilation opening is arranged in the outer side plate. A filtering device is arranged on at the first ventilation opening. The temperature sensor is electrically connected with the heat radiator and the temperature display. The ventilation hole is arranged on one side wall of the cabinet body and the heat radiator is arranged on the other side wall of the cabinet body.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a waterproof and dustproof electrical cabinet. Background technique [0002] At present, there are many types of outdoor electrical cabinets. Most of the electrical cabinets’ waterproof and dustproof structure and heat dissipation structure interact with each other. In design, one performance is often considered to weaken other performances. The entry of a large amount of dust and rain will inevitably cause the equipment in the electrical cabinet to work. abnormal. The inside of the existing electrical cabinet is a relatively sealed space. Although it has waterproof and dustproof effects, the heat dissipation effect is poor and cannot be automatically adjusted according to the temperature inside the electrical cabinet. [0003] In conclusion, how to design a waterproof and dustproof electrical cabinet with heat dissipation function has become one of the problems that those sk...

AI Technical Summary

Problems solved by technology

[0002] At present, there are many types of outdoor electrical cabinets. The waterproof and dustproof structure of most electrical cabinets and the heat dissipation structure affect each other. In the design, the performance of one aspect is often taken into account while the other performance is weakened. The entry of a large amount of dust and rain will inevitably cause the equipment in the electrical cabinet to work. abnormal

The interior of the existing electrical cabinet is a relatively sealed space. Although it has waterproof and dustproof effects, the heat dissipation effect is poor, and it cannot be automatically adjusted according to the temperature inside the electrical cabinet.
