[0002] High-voltage switchgear is a core power distribution device in a power system. It has intelligent monitoring and control functions, and can collect parameters such as voltage, current and insulation status in real time. Through automated management, it optimizes power distribution and prevents overload or short circuit risks. Its modular design improves maintenance efficiency and system reliability.

[0003] In high-voltage switchgear, circuit breakers are typically used to shut off the circuit inside the cabinet for easy maintenance. However, there may be a large number of switchgear, which makes circuit distribution and independent disconnection troublesome, and finding the corresponding switch is time-consuming, affecting practicality. Therefore, a high-voltage switchgear device that can quickly cut off power when the cabinet door is opened is needed. Utility Model Content

[0004] The purpose of this invention is to provide a non-contact, fast-break safety high-voltage switchgear to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-contact fast circuit breaking safety high-voltage switchgear, including an electrical cabinet, a lower door and a rotating door rotatably connected to one side of the electrical cabinet, and a stable disconnection mechanism and a touch-to-open mechanism are provided inside the electrical cabinet, wherein the stable disconnection mechanism is located on one side of the touch-to-open mechanism;

[0006] The stable disconnection mechanism includes a sliding box, which is fixedly connected inside the electrical cabinet. A connecting seat is fixedly connected inside the sliding box, and a sliding base is slidably connected inside the sliding box. The side of the sliding base that is close to the connecting seat is electrically connected. Magnets are fixedly connected to the side of the sliding base that is close to the connecting seat, and the magnets are arranged to repel each other. A sliding cylinder is fixedly connected to the side of the sliding base that is away from the connecting seat. A sliding plate is slidably connected inside the sliding cylinder. A spreading spring is fixedly connected between the side of the sliding plate that is close to the connecting seat and the inner wall of the sliding cylinder. A top rod is fixedly connected to the side of the sliding plate that is away from the spreading spring. Magnets are fixedly connected to the side of the sliding cylinder that is close to the revolving door, and the magnets are arranged to attract each other.

[0007] Preferably, the interior of the slide box is configured with a square structure.

[0008] Preferably, after the revolving door is closed, the magnet is in a closed state and the opening spring is in a compressed state.

[0009] Preferably, the end of the top rod is configured as a hemispherical structure.

[0010] Preferably, the touch-sensitive door opening mechanism includes a mounting platform, which is fixedly connected inside the electrical cabinet. A limit frame is fixedly connected to the side of the mounting platform near the revolving door. A fixed platform is fixedly connected to the side of the revolving door near the mounting platform. Multiple rotating seats are fixedly connected to the side of the fixed platform away from the mounting platform. A card is rotatably connected inside the upper part of the fixed platform.

[0013] Compared with the prior art, this utility model provides a non-contact, fast-break safety high-voltage switchgear, which has the following advantages:

[0014] The stable disconnection mechanism is used for autonomous and stable connection of the internal circuit of the cabinet. The mechanism uses the connecting seat and the slide as the circuit connection, and the repulsion of the magnets is used as the force for the two to quickly separate. With the help of the magnets, it can assist in dragging the slide away from the connecting seat when the cabinet is opened, providing double protection. At the same time, the mechanism uses the rotating door, the opening spring and the top rod to ensure that the connecting seat and the slide can fit tightly when the cabinet door is closed, increasing the stability of the circuit and providing a safe maintenance environment for workers.

[0015] The touch-sensitive door opening mechanism is used to quickly open and close the cabinet door, making the disconnection effect of the stable disconnection mechanism faster and reducing the risk of the cabinet door being electrified. The mechanism uses a pusher to drive a card so that the card engages with the limit frame. With the help of the card holder, card block and elastic element, the pusher is supported and limited, so that the cabinet door can be locked quickly. The worker can lightly press the card holder to make the card quickly disengage from the limit frame, ensuring high-efficiency opening and closing of the cabinet door and high-speed disconnection of the circuit.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a non-contact fast circuit breaking safety high voltage switch, including a cabinet 1, a lower door 2 and a rotating door 3 rotatably connected to one side of the cabinet 1, and a stable disconnection mechanism 4 and a touch-opening mechanism 5 are provided inside the cabinet 1, with the stable disconnection mechanism 4 located on one side of the touch-opening mechanism 5.

[0026] This mechanism is used to disconnect the internal circuit of the electrical cabinet 1. It solves the problems caused by the traditional method of shutting off power using a switch, and ensures stable disconnection. The stable disconnection mechanism 4 includes a sliding box 401, which is fixedly connected inside the electrical cabinet 1. A connecting seat 402 is fixedly connected inside the sliding box 401, and a sliding base 403 is slidably connected inside the sliding box 401. The side of the sliding base 403 closest to the connecting seat 402 is electrically connected. Both sides of the sliding base 403 and the connecting seat 402 are fixedly connected to... Magnet 404 is arranged to repel each other. A slide cylinder 405 is fixedly connected to the side of the slide block 403 away from the connecting seat 402. A slide plate 406 is slidably connected inside the slide cylinder 405. A spreading spring 407 is fixedly connected between the side of the slide plate 406 close to the connecting seat 402 and the inner wall of the slide cylinder 405. A top rod 408 is fixedly connected to the side of the slide plate 406 away from the spreading spring 407. Magnets 409 are fixedly connected to the sides of the slide cylinder 405 and the revolving door 3, and the magnets 409 are arranged to attract each other.

[0027] Furthermore, the interior of the slide box 401 is designed with a square structure.

[0028] Furthermore, after the revolving door 3 is closed, the magnet 409 is in a closed state, and the spring 407 is in a compressed state.

[0029] Furthermore, the end of the top rod 408 is designed as a hemispherical structure. Example

[0030] This mechanism is used for the rapid opening and closing of the revolving door 3. This mechanism, in conjunction with the stable disconnection mechanism 4, enables the cabinet door to be quickly opened and closed, allowing the stable disconnection mechanism 4 to quickly connect or disconnect. Please refer to [link / reference needed]. Figure 1-5 Furthermore, in conjunction with Embodiment 1, the touch-sensitive door opening mechanism 5 includes a mounting platform 501, which is fixedly connected inside the electrical cabinet 1. A limit frame 502 is fixedly connected to the side of the mounting platform 501 near the revolving door 3. A fixed platform 503 is fixedly connected to the side of the revolving door 3 near the mounting platform 501. Multiple rotating seats 504 are fixedly connected to the side of the fixed platform 503 away from the mounting platform 501. A card 505 is rotatably connected inside the upper end of the fixed platform 503. The card 505 is slidably connected between the mounting platform 501 and the limit frame 502. The rotating seats 504 are rotatably connected inside each of the following components. There is a push plate 506 and a card holder 507. The card holder 507 is located on the lower side of the push plate 506. A lifting rod 508 is fixedly connected to the upper end of the push plate 506. The lifting rod 508 abuts against the inner wall of the card 505. A card block 509 is fixedly connected to the lower end of the push plate 506. An elastic element 510 is fixedly connected between the card holder 507 and the fixed platform 503. A housing 511 is fixedly connected to the side of the revolving door 3 away from the mounting platform 501. The user can set the weight of the card 505 to press the push plate 506 or add a spring between the lower end of the push plate 506 and the fixed platform 503 to facilitate the card 505 to fall flexibly.

[0031] Furthermore, the card holder 507 has a card slot with the same volume as the card block 509 inside.

[0032] Furthermore, slots are provided inside the upper ends of the fixed platform 503 and the card 505, and an installation port for external communication is provided inside the revolving door 3.

[0033] In actual operation, when this device is used, the user pushes the rotating door 3 to bring it close to the electrical cabinet 1. Then, the user presses the push plate 506, causing it to drive the lifting rod 508 to lift the card 505. At this time, the card block 509 engages inside the card holder 507, and the push plate 506 is supported and limited by the elastic element 510 and the card holder 507. Because the card 505 is supported, it is embedded inside the limiting frame 502, providing a limit to the rotating door 3. The user only needs to press the card holder 507 to disengage it from the card block 509. The card 505 will fall under its own weight and disengage from the limiting frame 502. During this period, when the revolving door 3 is in contact with the electrical cabinet 1, the revolving door 3 abuts against the top rod 408, causing the opening spring 407 to be compressed. The opening spring 407 has a compression limit. After the revolving door 3 is in contact with the electric push, the top rod 408 will forcefully push the slide cylinder 405 to connect the slide seat 403 with the connecting seat 402. At the same time, the magnets 409 stick together and attract each other. After the user pulls open the revolving door 3, the rotation of the revolving door 3 causes the slide cylinder 405 to generate a pulling force. At the same time, the magnets 404 repel each other, causing the connecting seat 402 to disconnect from the slide seat 403, thereby quickly cutting off the circuit. At the same time, the opening spring 407 pushes the top rod 408 to reset.
