Description

Technical Field

[0001] This utility model relates to electrical component integration equipment, and more particularly to an electrical cabinet. Background Technology

[0002] An electrical cabinet is a device assembly that houses switching equipment, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. It is used for centralized control, distribution, and protection of circuits and electrical equipment, ensuring the safe, stable, and efficient operation of the electrical system. Electrical cabinets play a crucial role in electrical systems, and their functions are mainly reflected in the following aspects: Centralized control: Distributing dispersed electrical equipment centrally within the cabinet allows for unified operation of multiple devices via control switches and buttons, improving operational convenience and efficiency. Circuit distribution: Providing a stable power supply to each branch circuit according to the needs of different electrical devices. Safety protection: When overload, short circuit, or leakage faults occur, the protective devices within the cabinet quickly activate, cutting off the faulty circuit, preventing the fault from escalating, and protecting equipment and personnel safety. Monitoring and indication: Measuring instruments display electrical parameters in real time, and indicator lights visually reflect the equipment's operating status, helping operators to promptly grasp the system's operating conditions and facilitating fault diagnosis and maintenance.

[0003] Chinese Patent Publication No. CN110130810B discloses an electrical cabinet, including an electrical cabinet body, a door handle device fixedly disposed within the electrical cabinet body, a constant temperature sealing device fixedly disposed within the electrical cabinet body, and an electrical cabinet door rotating device fixedly disposed within the electrical cabinet body. The door handle device includes an electrical cabinet storage slot with an opening facing forward fixedly disposed within the electrical cabinet body. A rotatable electrical cabinet door is fixedly disposed within the electrical cabinet storage slot. A first electrical cabinet door handle is fixedly disposed at the left side of the front end of the electrical cabinet door.

[0004] However, existing technical solutions have the following drawbacks: the size and specifications of the cable bundles in electrical cabinets are usually standardized designs. Thick cables may not be able to be threaded through the cable bundle opening because it is too small, while thin cables may not be effectively fixed due to the large internal space, resulting in shaking or even slippage. If the cable bundle tightly binds multiple wires, it may hinder heat dissipation of the wires, leading to local temperature increases, accelerated insulation aging, and even short circuits or fires. Therefore, we propose an electrical cabinet to solve the problems mentioned above. Utility Model Content

[0019] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1-4 An electrical cabinet includes an electrical cabinet body 1. A fire extinguisher bracket 3 is fixedly installed on one side of the electrical cabinet body 1. A fire extinguisher 4 is fixedly installed inside the fire extinguisher bracket 3. Fire extinguishing nozzles 7 are equidistantly installed on one side inside the electrical cabinet body 1. A cable management structure 16 is fixedly installed on the inner rear wall of the electrical cabinet body 1. Cable bundles are equidistantly arranged inside the cable management structure 16. Each cable bundle has four cable bundles 17 equidistantly arranged. One end of the cable management structure 16 extends through and to the outside of the electrical cabinet body 1. A cable management cooling fan 18 is fixedly installed inside one side of the cable management structure 16.

[0021] Please see Figure 2-4 A U-shaped cable management box 20 is provided at the rear end of the cable management structure 16. An air intake filter 19 is fixedly installed on one side of the cable management structure 16 away from the cooling fan 18. Cable inlet grooves are provided at equal intervals at the upper and lower ends of the cable management structure 16. The cable inlet grooves include a first cable inlet groove 21, a second cable inlet groove 22 and a third cable inlet groove 23. The depth of the first cable inlet groove 21 is greater than that of the second cable inlet groove 22, and the depth of the third cable inlet groove 23 is less than that of the second cable inlet groove 22. The distance between the first cable inlet groove 21 and the second cable inlet groove 22, the distance between the second cable inlet groove 22 and the third cable inlet groove 23 and the distance between the first cable inlet groove 21 and the third cable inlet groove 23 are all the same. The width of the upper end of the cable management box 20 is smaller than that of the lower end. Both the upper and lower ends of the cable management box 20 have cover locking slots 25. A cover 24 is slidably installed on the front side of the cable management box 20. The lower end of the cover 24 is adapted to the lower cover locking slot 25. A cover locking block 26 is provided at the upper end of the cover 24, and the cover locking block 26 is adapted to the upper cover locking slot 25.

[0022] The upper two cable bundles 17 in the cable bundle assembly face upwards, and the lower two cable bundles 17 face downwards. Each cable bundle 17 includes a fixing plate 27, a partition plate 29, and a limiting plate. The limiting plate specifically includes a first limiting plate 28, a second limiting plate 30, and a third limiting plate 31. One end of the fixing plate 27 is fixedly connected to the cable management box 20. The cable management box 20 is perpendicular to its rear end. Two partition plates 29 are installed above the upper cable bundle 17 and two partition plates 29 are installed below the lower cable bundle 17. The fixing plate 27 is located away from the cable management box. A first limiting plate 28 is fixedly installed on one side of the inner wall of the cable management box 20. A second limiting plate 30 is fixedly installed on the side of the partition 29 away from the inner wall of the cable management box 20. A third limiting plate 31 is fixedly installed on the side of the partition 29 close to the inner wall of the cable management box 20. The distance between the second limiting plate 30 and the fixed plate 27 is smaller than the distance between the third limiting plate 31 and the fixed plate 27. The arrangement of the fixed plate 27, the partition 29, the first limiting plate 28, the second limiting plate 30 and the third limiting plate 31 forms a series of progressively increasing cable management spaces on the cable tie frame 17.

[0023] When organizing cables, since the wires of various electronic devices have different diameters, the wires are placed inside the first limiting plate 28, the second limiting plate 30, or the third limiting plate 31 according to their diameter. The internal space of the three limiting plates increases sequentially, thus enabling the organization of wires of different diameters. When placing the wire inside the third limiting plate 31, the wire is first inserted into the cable management box 20 through the first wire inlet slot 21, and then sequentially inserted into the third limiting plate 31 in the same row. When placing the wire inside the second limiting plate 30, the wire is first inserted into the cable management box 20 through the second wire inlet slot 22, and then sequentially inserted into the second limiting plate 30 in the same row. When placing the wire inside the first limiting plate 28, the wire is first inserted into the cable management box 20 through the third wire inlet slot 23, and then sequentially inserted into the first limiting plate in the same row. In step 28, when bundling the wires, first, the wires are bundled into the wire bundle rack 17 in the middle of the wire management box 20. The wires are separated vertically by the setting of limiting plates of different heights and the wire inlet groove, which improves the neatness of the wire bundle and increases the spacing between the wire bundles. After the wires are bundled, the box cover 24 is placed in front of the wire management box 20, and the lower end of the box cover 24 is inserted into the lower box cover locking slot 25. The box cover locking block 26 is inserted into the upper box cover locking slot 25 to fix the box cover 24. The wire management structure cooling fan 18 draws in air through the air intake filter 19 and blows it into the wire management box 20 by the wire management structure cooling fan 18, thereby cooling the wires in the wire management box 20 and preventing the wires from overheating, which would accelerate the aging of the insulation layer and even cause short circuits or fires.

[0024] Please see Figure 1 A PLC module 8 is fixedly installed at the top inside the electrical cabinet body 1. Five fuses 9 are installed at equal intervals below the PLC module 8. Five capacitor switching contactors 10 are installed at equal intervals below the fuses 9. Five current limiting resistors 11 are installed at equal intervals below the capacitor switching contactors 10. Five capacitors 12 are installed at equal intervals below the current limiting resistors 11.

[0025] Please see Figure 1 The front of the electrical cabinet body 1 is hinged and fitted with a cabinet door 2. The fire extinguisher 4 is a perfluorohexanone fire extinguisher, with a sealed solenoid valve 5 installed at its outlet. An air inlet pipe 6 is sealed above the solenoid valve 5, with one end extending into the interior of the electrical cabinet body 1 and sealingly connected to the fire extinguishing nozzle 7. Temperature sensors 13 are installed at the upper and lower ends inside the electrical cabinet body 1. A smoke sensor 14 is fixedly installed to one side of the upper temperature sensor 13. A carbon dioxide sensor 15 is fixedly installed at the lower end of one side of the inner wall of the electrical cabinet body 1, and a carbon monoxide sensor 32 is fixedly installed at the upper end of one side of the inner wall of the electrical cabinet body 1. The temperature sensor 13, smoke sensor 14, carbon dioxide sensor 15, and carbon monoxide sensor 32 are electrically connected to a PLC module 8, which is electrically connected to the fire extinguisher solenoid valve 5.

[0026] Working principle: During use, temperature sensor 13 monitors the temperature inside the electrical cabinet body 1 in real time and sends it to PLC module 8. Carbon monoxide sensor 32 and carbon dioxide sensor 15 monitor the concentration of carbon monoxide and carbon dioxide inside the electrical cabinet body 1 in real time and send it to PLC module 8. When PLC module 8 determines that the temperature reaches the critical value and the carbon monoxide or carbon dioxide content exceeds the set critical value, PLC module 8 controls the fire extinguisher solenoid valve 5 to open. The liquefied perfluorohexanone in the fire extinguisher 3 vaporizes due to the pressure change and enters the air inlet pipe 6. Guided by the air inlet pipe 6, it enters the fire extinguishing nozzle 7 and is sprayed out through the nozzle 10. After being released by the nozzle, the perfluorohexanone extinguishing agent quickly changes from liquid to gas, absorbs the heat generated by the battery, and rapidly reduces the temperature of the battery cell. Eliminating the temperature of the ignition source in the three elements of fire can play a role in extinguishing the fire.After vaporization, perfluorohexanone expands in volume, covering the entire protected area and thus isolating oxygen, reducing the content of oxidizers in the three elements of fire and bringing them below the combustion concentration to extinguish the fire. Because perfluorohexanone is highly stable, it undergoes chemical decomposition when the temperature in the protected area rises. Some bonds in the extinguishing agent molecules break and combine with active free radicals generated during combustion, blocking the chain reaction of combustion and providing chemical inhibition and extinguishing. This reduces misjudgments that can occur if temperature sensing is relied upon alone. (Note: The last sentence appears to be incomplete and possibly refers to wiring, possibly related to electronic components.) The wires come in various diameters. Depending on the wire's diameter, it is placed inside the first limiting plate 28, the second limiting plate 30, or the third limiting plate 31. The internal space of the three limiting plates increases sequentially, allowing for the organization of wires of different diameters. When placing the wire inside the third limiting plate 31, the wire is first inserted into the cable management box 20 through the first wire inlet groove 21, and then sequentially inserted into the third limiting plate 31 in the same row. When placing the wire inside the second limiting plate 30, the wire is first inserted into the cable management box 20 through the second wire inlet groove 22, and then sequentially inserted into the second limiting plate 30 in the same row. In step 0, when the wires need to be placed within the first limiting plate 28, the wires are first inserted into the cable management box 20 through the third wire inlet slot 23, and then sequentially inserted into the first limiting plates 28 in the same row. When bundling the wires, the wires are first bundled into the cable management rack 17 in the middle of the cable management box 20. The setting of limiting plates and wire inlet slots at different heights allows the wires to be separated vertically, thereby improving the neatness of the cable bundle and increasing the spacing between the cable bundles. After the cable bundle is completed, the box cover 24 is placed in front of the cable management box 20, and the lower end of the box cover 24 is inserted into the box cover locking slot 25 below, and the box cover locking is engaged. Insert the cover 26 into the upper cover locking slot 25 to secure the cover 24. Place the cover 24 into the front of the cable management box 20, inserting the lower end of the cover 24 into the lower cover locking slot 25. Insert the cover locking block 26 into the upper cover locking slot 25 to secure the cover 24. Turn on the cable management structure cooling fan 18. Air is drawn in through the air intake filter 19 and blown into the cable management box 20 by the cooling fan 18, thereby cooling the wires inside the cable management box 20 to prevent overheating and accelerated insulation aging, or even short circuits or fires.
