[0002] In modern electrical engineering, the efficiency and stability of power distribution are of vital importance. This requirement has led to the continuous advancement and development of combined power distribution methods to meet the growing demand for electricity, and combined distribution cabinets have also emerged accordingly.

[0003] At present, in the actual use of existing combined distribution cabinets, it is found that the internal wiring of the distribution cabinet is complicated and the connection and installation are difficult. In addition, each connector is prone to generate electric sparks or arcs at the moment of installation, which not only easily burns nearby electrical components and reduces their service life and performance, but also burns the insulation layer of the connecting wires, increasing the risk of leakage and short circuit. In addition, when a fire occurs during its use, the fire-fighting personnel can be informed through the control system in time, but cannot perform remote fire-fighting, thus missing the best rescue time, causing damage to the electrical equipment inside the distribution cabinet, and causing inconvenience to the maintenance and rescue personnel.

A plurality of power distributors 5 are installed on the upper end surface of the mounting plate 4. The power distributors 5 are connected to each other by a combination of mechanical and electrical connections. The power distributors 5 and the power access device 2 are connected by an electric spark shielding component 6.

[0021] The spark shielding assembly 6 includes a wire protection tube 61, and the wire protection tube 61 is symmetrically installed on the upper end surface of the distribution cabinet 1. A busbar is passed through the wire protection tube 61, and a threaded section is opened on the outer wall of the wire protection tube 61. A connecting ring 62 is screwed on the outer side of the threaded section, and an L-shaped connecting rod 63 is symmetrically installed on the outer wall of the connecting ring 62. The lower end of the L-shaped connecting rod 63 is fixedly connected to a sub-wire reel 64, and sub-wire holes are evenly opened on the sub-wire reel 64 along its circumference. Sub-wires are passed through the sub-wire holes, and a sub-wire tightening component 65 is provided at the position corresponding to the sub-wire hole in the sub-wire reel 64. A spark shielding component 66 is provided on the upper end of the distributor 5, and the upper end of the spark shielding component 66 and the lower end of the sub-wire are connected in a detachable manner.

[0022] The sub-line tightening component 65 includes a cylindrical slide groove 651, and a cylindrical slide groove 651 is opened at the position corresponding to the sub-line hole in the sub-line reel 64.

[0024] An isolation gasket 6621 is provided at the mouth of the insulating porcelain bottle 662 , and the isolation gasket 6621 is slidably connected to the upper connector 663 .

[0025] During the specific operation: first, manually install the distributor 5 on the mounting plate 4 as needed, then pass the busbar through the wire protection tube 61, and then remove the rubber sleeve at the lower end of the busbar to expose the sub-wires, toggle the lever 654 to compress the extrusion spring 652, and at the same time move the ball head wire presser 653 away from the sub-wire hole, and pass each sub-wire through the sub-wire hole and connect it to the sub-wire connector 665. During this process, the sub-wire tray 64 can be rotated according to the length of the sub-wire.

[0027] During specific operation: During the use of the combined power distribution system, if a fire occurs, the temperature on the top inner side of the power distribution cabinet 1 will rise sharply, the thermal decomposition cotton rope 77 will break due to thermal decomposition, and the high-pressure steel cylinder 72 will rotate downward and fall under its own gravity and continue to shake, while the sodium bicarbonate solution inside the bottle 73 will quickly mix with the aluminum sulfate solution, thereby producing a large amount of carbon dioxide. At this time, the internal pressure of the high-pressure steel cylinder 72 increases, the pressure valve 721 opens, and carbon dioxide is ejected from the pressure valve 721 and fills the entire power distribution cabinet 1, thereby realizing the function of rapid fire extinguishing.

[0028] In addition, the combined power distribution system includes: Power input module: used to receive external power; Distribution module: used to reasonably distribute power to different loads; Control module: used for intelligent control of the entire power distribution process; Output module: used to output power to various loads.

Then, the upper connector 663 is pressed downward to make the upper connector 663 contact the lower connector 661. The insulating oil in the insulating porcelain bottle 662 can prevent the generation of electric sparks. S3: During the use of the combined power distribution system, if a fire occurs, the temperature of the top inner side of the power distribution cabinet 1 will rise sharply, the thermal decomposition cotton rope 77 will break due to thermal decomposition, and the high-pressure steel cylinder 72 will fall downward under the action of its own gravity. At the same time, a large amount of carbon dioxide will be generated inside it, and the internal pressure of the high-pressure steel cylinder 72 will increase. The pressure valve 721 will open, and carbon dioxide will be ejected from the pressure valve 721, thereby realizing the function of rapid fire extinguishing.
