Electric power cabinet emergency protection device with fireproof and flame-retardant functions

Abstract

The invention relates to the field of power cabinet protection, in particular to a power cabinet emergency protection device with fireproof and flame-retardant functions. The technical problem is that when an electric power module of an electric power cabinet burns, flames of the electric power module can jump out from heat dissipation holes in the side of the electric power cabinet in the direction to ignite objects around the electric power cabinet, so that fire spreading is caused, and great potential safety hazards exist. According to the technical scheme, the power cabinet emergency protection device with the fireproof and flame-retardant functions comprises a box body, a closing assembly and the like; a closing assembly is installed on the lower portion of the box body. During use, heat dissipation holes of the box body are automatically blocked, so that an oxygen source needed by combustion is cut off, the fire extinguishing effect is achieved, meanwhile, carbon dioxide gas is automatically injected into the box body, the fire extinguishing effect is further improved, and meanwhile, dry powder is automatically, sufficiently and uniformly covered on the surface of an ignited object on the side edge of a ventilation opening of the box body; and the phenomenon of fire spreading is prevented, the phenomenon of dry powder blockage is prevented, and the phenomenon that fire extinguishing cannot be conducted on the ignition object due to dry powder blockage is avoided.

Description

technical field

[0001] The invention relates to the field of protection of power cabinets, in particular to an emergency protection device for power cabinets with fire-retardant and flame-retardant functions. Background technique

[0002] In the prior art, when the power cabinet is used in a high-temperature environment, the power module inside the power cabinet will overheat and short-circuit, resulting in spontaneous combustion of the power cabinet. During the use of the power cabinet, the door of the cabinet is closed, ready for fire extinguishing operation. When the fire is damaged, the staff needs to open the box door and then use a fire extinguisher to put out the power module inside. However, the box door of the power cabinet is in a high temperature state during the combustion. Manual direct contact with the box door is prone to burns, and the power module of the power cabinet burns. When the power module is installed, the flame will escape from the heat dissipation ...
