Abstract

The invention relates to a switch cabinet and a pressure-relief ventilation device thereof. The pressure-relief ventilation device comprises a pressure-relief cover arranged on a cabinet body, wherein a ventilation opening corresponding to a fan is formed in the pressure-relief cover, the fan is arranged on the outer side of the ventilation opening and is covered by a protective cover for preventing foreign matter from entering the cabinet body, and the protective cover is provided with vent holes. In the scheme, the pressure-relief cover can simultaneously serve as the constituent part for an air channel and a pressure-relief channel, the utilization rate is improved, the fan is arranged on the outer side of the ventilation opening, the effective usage space of the pressure-relief channel is not occupied, and the utilization rate of the pressure-relief channel is improved. In addition, the fan is covered with the protective cover, the protective cover can prevent foreign matter from entering the cabinet body, the different protection grade requirements of the switch cabinet can be met by changing the protective cover, meanwhile blades can be prevented from falling, and convenience is brought to maintenance. The problem that the fan in the ventilation device of the switch cabinet in the prior art occupies the pressure-relief channel is solved.

Description

technical field [0001] The invention relates to a switch cabinet and a pressure relief ventilation device thereof. Background technique [0002] Among the products of the power system, the medium and high voltage switchgear is one of the important equipment. With the rapid development of my country's electric power and switchgear manufacturing industry, people have put forward higher and more comprehensive requirements for the safety of the switchgear. The existing switchgear adopts a closed structure, which has great potential safety hazards. The switchgear includes multiple independent compartments, such as the handcart room, the main bus room, the circuit breaker room and the cable room. When a fault occurs in the compartment When an arc is generated, the internal temperature of the switchgear rises, resulting in an increase in the internal air pressure, and the gas is ejected from the front of the switchgear, causing accidents to operators, surrounding personnel, and equ...
