[0002] High-voltage distribution cabinets refer to electrical products with voltage levels ranging from 3.6kV to 550kV, used for switching, controlling or protecting the power generation, transmission, distribution, energy conversion and consumption of power systems. High-voltage distribution cabinets have functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and busbar connections.

[0003] Chinese invention patent publication number CN106607425A, published on May 3, 2017, discloses a safe treatment system for a power distribution system in a machinery plant. The system comprises a bottom support system, a water storage system, a power distribution system mounted above the bottom support system, and a roof mounted on top of the power distribution system. Above the bottom support system, a left-hand powder waste suction machine and a right-hand powder waste suction machine are mounted on the left and right sides of the power distribution system, respectively. A left-hand powder waste suction system and a right-hand powder waste suction system are mounted above the left and right powder waste suction machines, respectively. A support column mechanism is mounted in the center of the power distribution system. This system can remove powder waste as needed, and also facilitates drying and insulation treatments as needed, improving the operational convenience of the power distribution system in the machinery plant.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the safety handling system of the high-voltage distribution cabinet in the distribution system is not disclosed in detail. In the event of explosion and spontaneous combustion in the safety handling system of the high-voltage distribution cabinet, there are no specific response measures. Emergency handling is still carried out according to conventional measures, but the damage cannot be minimized, resulting in the inability to handle the situation quickly and minimize the losses once a fire occurs.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to solve the above technical problems and provide a high-voltage distribution cabinet safety processing system.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0009] Furthermore, the first aid unit includes a gas cylinder, an electric valve, an air pipe and a dispersion pipe; the gas cylinder is located in a power distribution cabinet; the gas cylinder is connected and fixedly connected to the electric valve; the output end of the electric valve is connected and fixedly connected to the gas pipe; the output end of the gas pipe is connected and fixedly connected to the dispersion pipe; and the dispersion pipe is symmetrically and evenly provided with through holes.

[0012] The present invention provides a high-voltage power distribution cabinet safety processing system, which has the following beneficial effects:

[0013] 1. The present invention uses temperature sensors and flame sensors to detect abnormal temperature and flames within the distribution cabinet. When excessive temperature or flames occur, the central processing unit controls the emergency unit to output carbon dioxide to fill the distribution cabinet and squeeze out oxygen, extinguishing the fire while also reducing the temperature. This cooling and fire extinguishing process is performed at the first sign of electrical component failure, resulting in high efficiency, rapidity, and reduced losses, solving the problems of low efficiency and high losses in existing safety processing systems.

[0026] The lower end of the gas cylinder 7 is fixedly connected to a cart 6; a second magnetic plate 5 is fixedly connected to the cart 6; a first magnetic plate 4 is fixedly connected to the corresponding second magnetic plate 5 in the distribution cabinet 1; during operation, the cart 6 and the gas cylinder 7 are detachably fixed in the distribution cabinet 1 through the magnetic connection between the second magnetic plate 5 and the first magnetic plate 4.
