Description

Technical Field

[0001] This invention relates to the field of ring network switch technology, and particularly to an AC metal ring network switchgear. Background Technology

[0002] Metal ring main units are electrical equipment consisting of a set of high-voltage switchgear installed in a steel plate metal cabinet or assembled into a modular ring main power supply unit. Its core components are load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] Patent CN217281846U discloses a fully insulated ring network switchgear, including a cabinet and a cable management mechanism. The cable management mechanism is located in the lower part of the cabinet's internal cavity, and the connecting seats in the cable management mechanism are installed on the lower parts of both sides of the cabinet's internal cavity. The cable management mechanism also includes a first spring, a connecting rod, a limiting tube, a baffle, a mounting seat, a second spring, a movable rod, and a wire pressing plate. This utility model, through the cable management mechanism, enables it to manage cables and store excess wires, while also facilitating the limiting and pressing of wires at connection points. This not only improves the neatness of the internal cables but also prevents wires from coming loose at connection points. The disassembly and assembly mechanism facilitates disassembly and assembly, not only allowing for the disassembly and assembly of the support components for electrical components but also facilitating the installation and removal of electrical components, thereby simplifying subsequent maintenance, repair, and replacement operations.

[0004] There are still some problems when using ring network switchgear.

[0005] Ring mainframe switchgear, as a key power distribution device in power distribution networks, is widely used in power distribution systems of industrial plants, commercial buildings, and residential communities. It integrates various components such as circuit breakers and instrument transformers, requiring the laying of numerous power, control, and signal lines. Traditional wiring methods often rely on cable ties for binding and fixing, lacking dedicated cable management structures. This leads to easy tangling and cross-contamination of wires, resulting in low space utilization within the cabinet, poor heat dissipation, insulation wear, and increased risk of short-circuit faults. Furthermore, the messy wire bundles significantly increase the difficulty of disconnecting and reconnecting wires during later maintenance, prolonging fault handling time. Summary of the Invention

When the card plate needs to be disassembled, the handle is pressed to move the insertion rod. The pressing of the handle causes the collar to compress the first spring. A docking ring is fixedly connected to the other end of the insertion rod, and the locking rod on the surface of the docking ring is locked inside the slot. The movement of the insertion rod causes the locking rod to disengage from the slot, thereby facilitating the disassembly of the entire card plate and making it convenient for wiring.

The same action is repeated to rotate the threaded rod. The rotation of the threaded rod causes the slider to slide on the slide bar, which facilitates the separation between the sliders and thus facilitates the separation of the wires inside the sleeve, avoiding entanglement between the wire harnesses.

The two ends of the second spring 418 are fixedly connected to one side of the sliding sleeve 417 and one side of the retaining ring 416, respectively. A mating plate 419 is fixedly connected to the surface of the sliding sleeve 417. An adjusting plate 420 is fixedly connected to the other end of the mating plate 419. A column 421 is fixedly connected to the bottom end of the adjusting plate 420. The column 421 is locked inside one of the positioning grooves 412. A driven rod 422 is fixedly connected to the top end of the adjusting plate 420.

[0039] Specifically, when inserting wires for different purposes into the corresponding sleeves 405 and then separating the wires, due to the limited space inside the housing 1, the handle 410 is pulled to rotate the threaded rod 408, and then the driven rod 422 is pulled to disengage the column 421 on the adjusting plate 420 from the positioning groove 412. The same action is repeated to rotate the threaded rod 408. The rotation of the threaded rod 408 causes the slider 403 to slide on the slide rod 402, which facilitates the separation of the sliders 403 and thus facilitates the separation of the wires inside the sleeve 405, avoiding tangling between the wire harnesses.

[0040] The working principle of this invention is as follows: Different types of wire harnesses are inserted into the slot plate 2 through the wire through hole 203 for wiring. When it is necessary to remove the card plate 202, the handle 205 is pressed to move the insertion rod 204. The pressing of the handle 205 causes the collar 210 to squeeze the first spring 211. A docking ring 206 is fixedly connected to the other end of the insertion rod 204, and the locking rod 207 on the surface of the docking ring 206 is locked inside the slot 209. The movement of the insertion rod 204 causes the locking rod 207 to disengage from the slot 209, thereby facilitating the removal of the entire card plate 202 for easy wiring.

[0041] Different wire harnesses are placed inside the wire management channel 301, and then the wire harnesses inside the wire management channel 301 are limited by the rotation of the baffle 303 to avoid tangling.

[0042] When inserting wires for different purposes into the corresponding sleeves 405 and then separating the wires, due to the limited space inside the housing 1, the handle 410 is pulled to rotate the threaded rod 408, and then the driven rod 422 is pulled to disengage the column 421 on the adjusting plate 420 from the positioning groove 412. The same action is repeated to rotate the threaded rod 408. The rotation of the threaded rod 408 causes the slider 403 to slide on the slide rod 402, which facilitates the separation of the sliders 403 and thus facilitates the separation of the wires inside the sleeve 405, avoiding tangling between the wire harnesses.
