Switch cabinet with high fireproof performance

Abstract

The invention relates to a switch cabinet with high fireproof performance, and belongs to the technical field of electrical equipment. A partition net and a cover plate are arranged on the top of theswitch cabinet body. The two ends of the cover plate are provided with connecting rods through downward vertical extending. The top of the side plate is provided with a second through hole opposite tothe lower part of the partition net. The bottom of the side plate is provided with a first through hole. A first baffle plate is correspondingly arranged at the position of the connecting rods relative to the first through hole. A second baffle plate is arranged at that second position of the connecting rod relative to the second through hole. An air bag is arranged between the partition net andthe cover plate. Sodium carbonate power is arranged in that air bag, When the interior of the switch cabinet is on fire, the fire source burns and explodes the air bag, the sodium carbonate powder inthe air bag extinguishes the fire and the cover plate moves downward accordingly so that the first baffle plate seals the first through hole and the second baffle plate seals the second through hole,the internal and external air is isolated, the fire source is enabled to be extinguished, the internal fire source can be extinguished without opening the cabinet door and the fire prevention performance of the switch cabinet is increased.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a switchgear with high fireproof performance. Background technique [0002] As we all know, multiple switch cabinets need to be installed in the power distribution system. During the operation of the electrical circuit, it is inevitable that there will be an electrical accident that will cause a fire in the switch cabinet. When a fire occurs in the switch cabinet, it is often necessary to open the door of the switch cabinet , and then put out the fire, but after a fire broke out in the switch cabinet, the internal fire situation is not clear, and it is very dangerous to open the cabinet door blindly. Contents of the invention [0003] In view of the problems in the background, the object of the present invention is to provide a switchgear with high fire performance. [0004] In order to achieve the above object, the present invention provides a switchg...
