Fireproof explosion-proof high-low voltage switch cabinet

Abstract

The invention discloses a fireproof explosion-proof high-low voltage switch cabinet, which relates to the technical field of switch cabinets. The fireproof explosion-proof high-low voltage switch cabinet comprises a cabinet body, a cabinet door and an explosion-proof device, wherein the cabinet door used for displaying the temperature of each cavity of the switch cabinet is hinged to the front face of the cabinet body; the explosion-proof device used for ventilation and air diffusion is fixedly installed in the cabinet body; and an air inlet fan, a dust exhaust hole and a filter plate are arranged in the cabinet body. A controller, the air inlet fan and an exhaust fan are arranged, external air is extracted by the air inlet fan and is sequentially filtered by a first filter hole and a second filter hole to effectively filter impurities, and the problem that impurities easily enter the switch cabinet to block electrical equipment due to a conventional heat dissipation mode is solved. The device is good in filter effect, prevents impurities from blocking electrical equipment and reduces the heat dissipation effect, prolongs the service life of the electrical equipment, reduces the probability of open fire of the electrical equipment caused by overheating, and prolongs the service life of the device.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a fireproof and explosion-proof high and low voltage switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load reducer, but the existing switchgear still has the following deficiencies: [0003] In the prior art, the interior of the switchgear is composed of multiple chambers. Since the electrical equipment will generate heat during use, the high temperature may cause the electrical equipment to generate open flames or even explode. Due to th...

Problems solved by technology

[0003] In the prior art, the interior of the switchgear is composed of multiple chambers. Since the electrical equipment will generate heat during use, the high temperature may cause the electrical equipment to generate open flames or even explode. Due to the high cost of the switchgear, the conventional switchgear Generally, a fan is installed for heat dissipation, but the conventional heat dissipation method is too simple, and impurities can easily enter the interior of the switch cabinet through the fan to block the electrical equipment, thereby reducing the heat dissipation effect of the electrical equipment and easily burning out, resulting in an explosion of an open flame. The response time of electrical fires is fast and The smoke process is temporarily replaced by an open flame, and the use effect is not ideal
