Description

Dustproof heat dissipation type low-voltage switch cabinet Technical Field The application relates to the technical field of electrical equipment, in particular to a dustproof heat dissipation type low-voltage switch cabinet. Background The low-voltage switch cabinet is a closed vertical complete equipment assembled by one or more low-voltage switch appliances and associated secondary equipment such as measurement, control, protection and the like, and is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries to be used for power transmission, distribution and electric energy conversion. In the field of power systems, low-voltage switch cabinets are widely applied, and play a key role in guaranteeing stable distribution and safe transmission of power as important electrical equipment. With the continuous development of the power industry, the performance requirement on the low-voltage switch cabinet is increasingly improved, and the low-voltage switch cabinet not only has high-efficiency and stable electric energy distribution capability, but also can adapt to different use environments and working conditions so as to meet the requirements of various electric equipment. In many scenes such as industrial production, commercial buildings and residential electricity consumption, the low-voltage switch cabinet plays an indispensable role, and the performance of the low-voltage switch cabinet directly influences the operation efficiency and the safety of the whole power system. In the conventional low-voltage switch cabinet technology, in order to solve the problem of heat dissipation of the cabinet body, a mode of providing a large-area ventilation opening on the side surface or the back surface of the cabinet body is generally adopted, so that air naturally convects to take away heat. There are also some simple fans installed inside the cabinet body, and the air flow is accelerated by the rotation of the fans, so that the purpose of heat dissipation is achieved. In addition, some methods are to wrap the heat insulation material outside the cabinet body so as to reduce the influence of external heat on the interior of the cabinet body. However, these existing heat dissipation means have obvious drawbacks. The large-area ventilation openings can promote natural convection of air, but dust, sundries and the like can easily enter the cabinet body, and normal operation of electric elements is affected. If the vent is provided with the dust screen, the gap of the dust screen with higher dustproof effect is smaller, so that the dust screen can not only reduce the air flow speed, but also be covered and blocked by dust for a long time, thereby influencing the radiating effect.
