Power control cabinet with self-sealing structure after fire

Abstract

The invention discloses an electric power control cabinet with a post-fire self-sealing structure, and belongs to the field of electric power control cabinets, and the electric power control cabinet with the post-fire self-sealing structure is characterized in that a plurality of ventilation slots are uniformly formed in a side cabinet plate, so that the interior of a cabinet body can be ventilated under daily conditions; the blocking plates are slidably connected into the cavities formed in the side cabinet plates, the conduction grooves corresponding to the ventilation grooves are evenly formed in the blocking plates, and the blocking plates are matched with supporting of the glass columns, so that the ventilation grooves can be automatically blocked in a staggered mode when fire breaks out in the cabinet body, flames in the cabinet body are effectively prevented from escaping outwards, and the service life of the cabinet body is prolonged. And the safety after the device is on fire is improved to a certain extent.

Description

technical field [0001] The invention relates to the field of power control cabinets, and more particularly, to a power control cabinet with a self-sealing structure after a fire. Background technique [0002] The power control cabinet is a power control unit formed by assembling switchgear, measuring instruments, protective appliances and other equipment in a metal cabinet according to electrical wiring requirements. It is widely used in various control circuits and is a common power control equipment. . [0003] Since each component inside the power control cabinet will generate a high temperature during operation, in order to ensure the stable operation of the components inside the power control cabinet, a plurality of cooling ports are usually opened on the side wall of the power control cabinet. Under normal working conditions, the hot air inside the power control cabinet can be exhausted through the heat dissipation port. However, if the interior of the power control c...

Problems solved by technology

[0003] Since the various components inside the power control cabinet will generate high temperature during operation, in order to ensure the stable operation of the components inside the power control cabinet, multiple heat dissipation ports are usually opened on the side wall of the power control cabinet. Under normal working conditions, the hot air inside the power control cabinet can be exhausted through the cooling vents. However, if the inside of the power control cabinet is affected by a fault and causes a fire, the cooling vents that are not blocked in time will easily cause the flames inside the cabinet to radiate outwards. Jumping out, it is easy to ignite the surrounding things and cause more serious accidents and losses
