specific Embodiment approach

[0035] Specific implementation: In the initial state, the limit rod 6 is inserted into the limit hole 27 on the flame-retardant plate 5 through the guide sleeve 7, so that the flame-retardant plate 5 is placed in the heat dissipation hole under the action of the limit rod 6 2 On the upper side, when the PLC controls the electromagnet 9 to be energized, the electromagnet 9 generates magnetism that attracts the permanent magnet 8, and under the action of mutual attraction, the permanent magnet 8 moves toward the electromagnet 9, so that the limit rod 6 is disengaged The limit hole 27 realizes that the limit component loses the restriction on the position of the flame-retardant plate 5. When a fire breaks out in the space formed by the cabinet body 1 and the cabinet door 3, the probe 11 transmits the monitored information to the PLC, and the PLC controls the limit The positioning component moves, so that the limiting component loses its limiting effect on the flame-retardant plate...

Abstract

The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a flame-proof function, which comprises a cabinet body, a base fixed at the bottom of the cabinet body and a cabinet door hinged with the cabinet body, a plurality of heat dissipation holes are uniformly formed in one side surface of the cabinet body, and flame-retardant plates for blocking the heat dissipation holes are arranged on the inner sides of the heat dissipation holes. Vertically-arranged L-shaped guide rails are arranged on the two sides of the flame-retardant plates correspondingly, limiting assemblies used for limiting the positions of the flame-retardant plates are arranged on the upper sides of the L-shaped guide rails, positioning assemblies used for limiting the positions of the flame-retardant plates are installed on the lower portions of the back faces of the two L-shaped guide rails, and a horizontally-arranged supporting plate is fixedly connected to the lower ends of the L-shaped guide rails; an inert gas tank is arranged on the lower side of the supporting plate, and a sealing assembly is installed in the middle of the upper surface of the inert gas tank, and compared with the prior art, the cabinet has the following advantages that the effect of isolating air is achieved, and external air is prevented from continuously entering the space formed by the cabinet body and the cabinet door.

Description

technical field [0001] The invention relates to a power distribution cabinet with a flameproof function, which belongs to the technical field of power distribution cabinets. Background technique [0002] The power distribution cabinet is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. At present, when a fire breaks out inside the power distribution cabinet, because the heat dissipation holes on the power distribution cabinet are in an open state, exter...
