Electrical distribution cabinet

Abstract

The invention relates to an electrical distribution cabinet, comprising a power distribution cabinet body, an electric appliance fixed mounting frame disposed inside the power distribution cabinet body, and a first heat dissipating device disposed on two sides of the power distribution cabinet body. The power distribution cabinet body has a cubic structure with a mounting cavity inside. The electric appliance fixed mounting frame is disposed in the mounting cavity. The first heat dissipating device includes an air draft mechanism, an air inlet mechanism and a ventilation duct. The power distribution cabinet body is provided with an air inlet in the side wall. The air inlet mechanism is disposed at the side wall of the power distribution cabinet body and is located at the air inlet. One endof the ventilation duct is connected with the air inlet mechanism, and the other end of the ventilation duct is connected with the air draft mechanism. The air draft mechanism performs air draft in the ventilation duct, so as to form air convection inside and outside the power distribution cabinet body to dissipate heat from the electrical distribution cabinet. The electrical distribution cabinetof the invention makes the air flow in the ventilation duct, takes away the heat in the power distribution cabinet, and prevents the external air from directly flowing into the power distribution cabinet and the dust contained in the air from adhering to electrical equipment, which causes damage to the electrical equipment.

Description

technical field [0001] The invention belongs to the technical field of electrical distribution cabinets, and in particular relates to an electrical distribution cabinet. Background technique [0002] The power distribution cabinet is an important device in the power system and the final equipment of the power distribution system. Distribution cabinets are widely used in various industries. However, a large amount of dust tends to accumulate in the existing power distribution cabinets, which not only reduces the aesthetics and usability of the power distribution cabinets, but more importantly, causes the equipment in the power distribution cabinets to deteriorate and be easily damaged. In addition, Excessive dust will also reduce the heat dissipation performance of the power distribution cabinet. In addition, existing power distribution cabinets generally have the defect of poor heat dissipation. Excessive dust will reduce the service life of the power distribution cabinet a...
