[0002] Distribution cabinet is a general term for motor control center. Distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits; motor control center is used in the occasions where the load is concentrated and there are more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The distribution cabinet is an important component of electrical engineering. The distribution cabinet used in electrical engineering has relatively high requirements for the environment, and the materials used are mostly fire-resistant and fire-proof materials. However, the phenomenon of distribution cabinet burning also occurs from time to time. The distribution cabinet is the final equipment of the distribution system. Once burned, it will cause regional power outages, affecting residents' lives and factory production. At the same time, when the distribution cabinet burns, it will produce open flames, causing safety hazards to surrounding residents and need to be extinguished in time. At the same time, the existing distribution cabinets for electrical engineering cannot provide early warning when a fire occurs, which is not conducive to user use and reduces the practicality of the distribution cabinet. Summary of the invention

[0004] In order to improve the above-mentioned problem that early warning cannot be achieved, which is not conducive to user use and reduces the practicality of the distribution cabinet, the present invention provides a distribution cabinet with early warning function and an early warning system thereof.
