[0012] Preferably, a sealing strip is fixedly installed at the bottom of the movable plate, and the sealing strip corresponds to the heat dissipation hole. The sealing strip can seal between the movable plate and the heat dissipation hole.

[0013] The present invention provides a low-voltage power distribution cabinet with an internal protection device. Compared with the prior art, it has the following beneficial effects: Through the mutual cooperation of the movable plate, the binding strap and the partition board, the wires of the electrical equipment in the cabinet body are extended out of the cabinet body through the wiring holes, and then the wiring holes are sealed with sealant clay. When a fire breaks out in the electrical equipment in the cabinet body, the partition board absorbs the heat of the fire and then conducts the heat flow, so that the heat heats and melts the binding strap, causing the movable plate to flip downward, which can seal the heat dissipation holes, facilitating the isolation of the outside air, thereby realizing the sealed fire extinguishing inside the cabinet body, facilitating the internal protection operation of the cabinet body. The partition board can isolate the electrical equipment in the cabinet body to prevent damage to other electrical equipment when a fire breaks out in the electrical equipment.
