Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet with a protective structure. Background Art
[0002] Distribution cabinets are a general term for motor control centers. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load and are used in situations where the load is concentrated and there are many circuits. However, existing distribution cabinets generally have heat dissipation ports on the cabinet door or cabinet body. However, due to the high voltage and high heat inside, the heat dissipation effect is poor, resulting in a high temperature inside the distribution cabinet, which is prone to thermal and electrical fires. At the same time, since there are electrical components inside the distribution cabinet, if the fire cannot be effectively and quickly extinguished after a fire occurs, there will be great safety hazards.
[0003] In view of the above problems, the invention with patent announcement number CN111641122B discloses a safety protection distribution cabinet, which includes a cabinet body, a cabinet door and a door lock; the cabinet door is movably arranged on the edge of the front wall of the cabinet body, and the door lock is fixedly arranged on the rear side wall of the cabinet door, and one end of the cabinet door is movably embedded in the cabinet door and is located on the center line. The present invention relates to the technical field of distribution cabinets. Electrical components can be installed through the carrier frame, and the storage space can be increased with the help of the first storage body and the second storage body to collect dry powder for fire extinguishing; the first baffle and the second baffle are controlled to move up and down in conjunction through the electric telescopic rod in the heat dissipation structure to achieve heat dissipation through the flow of inlet and outlet air, and can also be closed to form a seal so that there is no oxygen after a fire, thereby avoiding the increase of the fire; the temperature sensor in the fire extinguishing structure senses that the temperature rises to a certain extent after the fire, and controls the solenoid valve to open to use a dry powder fire extinguisher to extinguish the fire.
[0004] The power distribution cabinet is opened by a solenoid valve to extinguish the fire with the help of a dry powder fire extinguisher. However, the solenoid valve is connected to the dry powder fire extinguisher, and the dry powder fire extinguisher is opened with the help of the solenoid valve. This dry powder fire extinguisher needs to be customized before it can be connected to the solenoid valve. The dry powder fire extinguisher purchased on the market cannot be used, and it needs to be customized and purchased separately, which is more troublesome. In addition, the dry powder fire extinguisher and the solenoid valve are connected by pipes for a long time. Once a leak occurs, it is not easy to close, resulting in the inability to use it for fire extinguishing. Utility Model Content
