The second composite sleeves are connected to the first composite sleeves via flanges. An upper terminal is provided at the top of the first composite sleeve, and a vacuum interrupter is provided inside the first composite sleeve.

[0004] Existing permanent magnet outdoor high-voltage intelligent vacuum circuit breakers require connection to an external control box via cables. These cables are plugged into interfaces on the circuit breaker body. During implementation, the cables can experience traction due to shaking or pulling, which directly affects the stability of the connection between the plug and the interface. Therefore, there is an urgent need to develop a new type of permanent magnet outdoor high-voltage intelligent vacuum circuit breaker to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to propose a novel permanent magnet outdoor high-voltage intelligent vacuum circuit breaker in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel permanent magnet outdoor high-voltage intelligent vacuum circuit breaker includes a circuit breaker body, which includes a housing and an interface. A connecting frame is provided on the outer side of the interface and is fixedly connected to the outer wall of the housing. A triangular groove is provided inside the connecting frame. A retaining frame is detachably connected to the open end of the connecting frame. A fixing component for fixing cables to the connecting frame is provided on the outer wall of the retaining frame.

[0007] Preferably, a fixing plate is fixedly connected to the outer wall of the machine body by a fixing rod, and a connecting rope is fixedly connected between the fixing plate and the frame.

[0008] Preferably, the frame has a U-shaped structure, and the horizontal end of the frame is fixedly connected to the outer wall of the connecting frame by a fastening rod.

[0009] Preferably, the outer wall of the connecting frame is integrally formed with a mounting bracket, and the horizontal end of the mounting bracket is fixedly connected to the outer wall of the machine body by a locking rod.

[0010] Preferably, the fixing component includes a fixing plate and a pushing part for pushing the fixing plate to translate, wherein the outer wall of the fixing plate is slidably connected to the inner wall of the connecting frame through a central groove.

[0011] Preferably, the pushing part includes a pushing rod that is screwed into the inner surface wall of the vertical end of the frame, and the open end of the pushing rod is rotatably connected to the outer surface wall of the fixed plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this application, after the plug and interface are connected, the cable is joined to the connecting frame through the notch. The notch is then sealed by the connecting frame, and the connecting frame and the connecting frame are fixed. At this time, the fixing plate is placed in the middle groove. The push rod is rotated to make it screw into the connecting frame. The push rod pushes the fixing plate to slide along the middle groove until the fixing plate pushes the cable to be stably joined to the corresponding area of ​​the triangular groove. This achieves local positioning of the cable and avoids the traction force generated by the cable from directly acting on the connection between the cable and the interface. This improves the stability of the permanent magnet outdoor high voltage intelligent vacuum circuit breaker. In addition, the triangular groove, together with the horizontally movable fixing plate, can adapt to the positioning of cables of different sizes.

[0013] 2. In this application, the fixed plate and the connecting rope limit the position of the frame after the separation of the connecting frame, so that when it is necessary to keep the gap open, the frame can be suspended at the bottom of the machine body without having to hold it continuously by a person to ensure the position of the frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A novel permanent magnet outdoor high voltage intelligent vacuum circuit breaker includes a circuit breaker body 1. The circuit breaker body 1 includes a body 101 and an interface 102. A connecting frame 2 is provided on the outside of the interface 102 and is fixedly connected to the outer wall of the body 101. A triangular groove 3 is provided inside the connecting frame 2. A retaining frame 9 is detachably connected to the open end of the connecting frame 2. A fixing component for fixing cables to the connecting frame 2 is provided on the outer wall of the retaining frame 9. After plugging the plug into the interface 102, connect the cable to the connecting frame 2 through the notch. Then seal the notch with the mounting frame 9 and fix the mounting frame 9 to the connecting frame 2. At this time, the fixing plate 12 is placed in the middle groove 13. Rotate the push rod 10 to make it screw into the mounting frame 9. The push rod 10 pushes the fixing plate 12 to slide along the middle groove 13 until the fixing plate 12 pushes the cable to be stably connected to the corresponding area of ​​the triangular groove 3. This achieves local positioning of the cable and avoids the traction force generated by the cable from directly acting on the connection between the cable and the interface 102. This improves the stability of the permanent magnet outdoor high voltage intelligent vacuum circuit breaker. In addition, the triangular groove 3, together with the horizontally movable fixing plate 12, can adapt to the positioning of cables of different sizes.

[0018] Specifically, such as Figure 2 and Figure 4 As shown, a fixing plate 6 is fixedly connected to the outer wall of the body 101 via a fixing rod 7. A connecting rope 8 is fixedly connected between the fixing plate 6 and the frame 9. The fixing plate 6 and the connecting rope 8 restrict the position of the frame 9 after the separation of the connecting frame 2 to be stable, so that when it is necessary to keep the gap open, the frame 9 can be suspended at the bottom of the body 101 without having to hold it continuously to ensure the position of the frame 9.

[0019] Specifically, such as Figure 2 and Figure 3As shown, the frame 9 has a U-shaped structure. The horizontal end of the frame 9 is fixedly connected to the outer wall of the connecting frame 2 via a fastening rod 11, ensuring the ease of assembly and disassembly of the frame 9. The outer wall of the connecting frame 2 is integrally formed with a mounting bracket 4. The horizontal end of the mounting bracket 4 is fixedly connected to the outer wall of the machine body 101 via a locking rod 5, ensuring the ease of assembly and disassembly of the connecting frame 2. The fixing component includes a fixing plate 12 and a pushing part for pushing the fixing plate 12 to move horizontally. The outer wall of the fixing plate 12 is slidably connected to the inner wall of the connecting frame 2 via a central groove 13 to limit the axial deflection of the fixing plate 12. The pushing part includes a pushing rod 10 that is screwed into the inner wall of the vertical end of the frame 9. The open end of the pushing rod 10 is rotatably connected to the outer wall of the fixing plate 12. Rotating the pushing rod 10 causes it to screw into the frame 9, and the pushing rod 10 pushes the fixing plate 12 to slide along the central groove 13.

[0020] Working principle: After plugging the plug into the interface 102, the cable is connected to the connecting frame 2 through the notch. The notch is then sealed by the mounting frame 9, and the mounting frame 9 and the connecting frame 2 are fixed. At this time, the fixing plate 12 is placed in the middle groove 13. The push rod 10 is rotated to make it screw into the mounting frame 9. The push rod 10 pushes the fixing plate 12 to slide along the middle groove 13 until the fixing plate 12 pushes the cable to be stably connected to the corresponding area of ​​the triangular groove 3. This achieves local positioning of the cable and avoids the traction force generated by the cable from directly acting on the connection between the cable and the interface 102, which improves the stability of the permanent magnet outdoor high voltage intelligent vacuum circuit breaker. The triangular groove 3, together with the horizontally movable fixing plate 12, can adapt to the positioning of cables of different sizes. The fixing plate 6, together with the connecting rope 8, restricts the position of the mounting frame 9 after separating the connecting frame 2 to be stable. This allows the mounting frame 9 to be suspended at the bottom of the body 101 when it is necessary to keep the notch open, without having to hold it continuously to ensure the position of the mounting frame 9.

[0021] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
