Abstract

The invention relates to the technical field of switch cabinets, discloses a high-safety intelligent pressure relief device for a switch cabinet, and solves the problems that an existing pressure relief device for the switch cabinet is poor in pressure relief effect and low in pressure relief speed, potential safety hazards exist in the pressure relief process, and ventilation and heat dissipation cannot be effectively conducted on the interior of the switch cabinet in the pressure relief process. The high-safety intelligent pressure relief device comprises a cabinet body, a lifting top cover and a control system, wherein the lifting top cover is installed at the top part of the cabinet body, a protective sealing assembly is installed between the lifting top cover and the cabinet body, the top parts of the two sides in the cabinet body are each provided with two pressure detection ends, and a lifting power mechanism is mounted between the top part in the cabinet body and the bottom part of the lifting top cover. The high-safety intelligent pressure relief device for the switch cabinet is provided with the effective pressure measurement and control mechanisms, the effectiveness and safety of pressure relief can be ensured through a control system, ventilation and heat dissipation can be effectively carried out in the pressure relief process, and high-temperature and high-pressure gas in the switch cabinet can be effectively dissipated.

Description

technical field [0001] The invention belongs to the technical field of switch cabinets, in particular to a high-safety intelligent pressure relief device for switch cabinets. Background technique [0002] Switchgear is a kind of switchgear suitable for power consumption occasions. Its main function is to switch, control and protect the power system during the process of power generation, transmission, distribution and power conversion. It is mainly used in power plants and substations. , petrochemical industry, metallurgical steel rolling, light industry textiles, factories and mines, residential quarters, high-rise buildings and other occasions; during the use of switchgear, internal arc faults are circuit short circuits caused by various reasons, which is the most serious problem of switchgear. Fault, the arc produces heat effect and pressure effect. If the high temperature and high pressure gas cannot be effectively released in a very short time in the narrow cabinet, it ...
