They are mainly used in steam transmission systems in the petrochemical industry and feature creep monitoring and an operating temperature limit of 450℃. In medium-pressure systems, the switching device is crucial in various scenarios such as normal operation scheduling, reactive power compensation, and system protection. It can be used for planned operations and can also automatically activate in case of failure, making it a core device for ensuring the safe, stable, and efficient operation of the system.
[0003] When existing switching devices are in use, there are issues such as untimely response from the issuance of control commands to the start of mechanical mechanisms or long response times during the switching process. This inherent delay results in a significant delay between the actual operation commands and the executed actions, affecting the continuity and stability of the actual workflow that relies on rapid power regulation.
[0004] Based on this, the present invention provides a medium-voltage system rapid switching device with voltage stabilization and regulation to solve the above problems. Utility Model Content

Each of the three mounting brackets is fixedly connected to a fixing rod. Each of the three mounting brackets contains a tension spring. Hooks at one end of each of the three tension springs are respectively hooked onto the three lifting rings, and hooks at the other end of each of the three tension springs are respectively hooked onto the three fixing rods.

Detailed Implementation
[0022] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.
[0023] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.
[0024] This invention relates to a rapid switching device for medium-voltage systems with voltage stabilization and regulation. Existing switching devices suffer from response delays and slow operation, resulting in actual operation lagging significantly behind control commands, which seriously affects the continuity and stability of the rapid power regulation system.
[0025] As an example, such as Figure 1 and Figure 2 This utility model includes a mounting base 1, three mounting brackets 2 fixedly connected to one side of the mounting base 1, pins 3 rotatably connected to each of the three mounting brackets 2, cutting plates 4 fixedly connected to each of the three pins 3, guide plates 5 fixedly connected to one side of each of the three cutting plates 4, lifting rings 6 fixedly connected to one side of each of the three guide plates 5, fixing rods 7 fixedly connected to the top of each of the three mounting brackets 2, tension springs 8 provided inside each of the three mounting brackets 2, hooks at one end of each of the three tension springs 8 respectively hooked onto the three lifting rings 6, hooks at the other end of each of the three tension springs 8 respectively hooked onto the three fixing rods 7, the three pins 3 are connected together by a fixing shaft 10, a stop bar 13 is provided on one side of the fixing shaft 10, the fixing shaft 10 limits the cutting plates 4 by the stop bar 13.
[0026] In this embodiment, during use, the cutting plate 4 is pushed to rotate on the pin 3, causing the cutting plate 4 to rotate to a straight upward direction. During the rotation, the tension spring 8 is pulled by the lifting ring 6, and the other end of the tension spring 8 is limited by the fixing rod 7. During the continuous rotation of the cutting plate 4, the tension spring 8 is pulled by the lifting ring 6 and undergoes elastic deformation, thereby performing energy storage operation. The tension spring 8 is guided and protected by the guide plate 5 to avoid squeezing damage to the tension spring 8, and the fixed shaft 10 is limited by the stop rod 13 on one side, thereby limiting the cutting plate 4. When cutting is required, the stop rod 13 on one side of the fixed shaft 10 is released. At this time, the lifting ring 6 on one side of the cutting plate 4 is pulled by the tension spring 8, thereby pulling the cutting plate 4 on one side to rotate 90 degrees in the opposite direction, thereby completing the cutting operation.
[0027] As an example, such as Figure 1 and Figure 2 A handle 11 is fixedly connected to one end of the fixed shaft 10, and a fixed ring 12 is fixedly connected to the fixed shaft 10. The fixed ring 12 is located between the mounting bracket 2 and the handle 11. One end of the stop bar 13 is fixedly connected to the fixed ring 12, and a synchronizing rod 9 is passed through the three cutting plates 4.
[0028] As an example, such as Figure 4 A mounting bracket 14 is fixedly connected to one side of the mounting base 1. A rotating shaft 15 is fixedly connected inside the mounting bracket 14. A limiting blade 16 is rotatably connected to the rotating shaft 15. The fixed shaft 10 cooperates with the limiting blade 16 through a stop bar 13.
[0029] In this embodiment, after the cutting is completed, the operator can push the fixed shaft 10 to rotate through the handle 11, thereby driving the pin 3 to rotate on the mounting frame 2, and driving the cutting plate 4 to rotate and reset. Through the synchronizing rod 9, the three cutting plates 4 can keep rotating synchronously, thereby ensuring the cutting requirements. The stop bar 13 on one side of the fixed shaft 10 is limited by the limiting blade 16. When cutting is required, the insert plate 19 moves out from the limiting blade 16, and the limiting blade 16 can rotate freely. At this time, the stop bar 13 is no longer limited by the limiting blade 16, thereby allowing the cutting operation.
[0030] As an example, such as Figure 4 A groove 17 is provided on one side of the mounting base 1, and a slider 18 is slidably connected in the groove 17. An insert plate 19 is fixedly connected to one side of the slider 18, and the insert plate 19 cooperates with the limiting blade 16.
[0031] As an example, such as Figure 4 Limiting grooves 20 are provided on both sides of the slide groove 17, and limiting blocks 21 are fixedly connected to both sides of the slider 18. The two limiting blocks 21 are slidably connected in the two limiting grooves 20 respectively.
[0032] As an example, such as Figure 4 An electromagnet 22 is fixedly connected to one side of the slide 17. The electromagnet 22 is connected to the power supply and the controller. A cable hole 24 is opened on one side of the slide 17. A magnetic block 23 is fixedly connected to the other side of the slider 18. The electromagnet 22 and the magnetic block 23 cooperate with each other.
[0033] In this embodiment, by supplying power to the electromagnet 22, the side of the electromagnet 22 near the magnetic block 23 is magnetized. According to the principle of like poles repelling each other, the electromagnet 22 generates a repulsive force on the magnetic block 23, pushing the magnetic block 23. This pushes the slider 18 to slide within the groove 17. The slider 18 pushes the insert plate 19 on one side to insert into the limiting blade 16, thus limiting the limiting blade 16. While the slider 18 slides within the groove 17, the limiting blocks 21 on both sides of the slider 18 slide within the two limiting grooves 20, limiting the slider 18. When cutting is required, the electromagnet 22 is de-energized, and the electromagnet 22 no longer generates a repulsive force on the magnetic block 23. At this time, the stop bar 13 on one side of the fixed shaft 10 rotates, pushing the limiting blade 16 to rotate. The rotation of the limiting blade 16 pushes the inserted insert plate 19 back, pushing the slider 18 back into the groove 17, allowing the limiting blade 16 to enter a free rotation state, thereby avoiding affecting the actual cutting operation.
[0034] Working principle of this utility model:
[0035] By rotating the fixed shaft 10 through the handle 11, the pin 3 is driven to rotate on the mounting bracket 2, thereby causing the cutting plate 4 to rotate upward. The tension spring 8 is pulled by the lifting ring 6 on one side of the cutting plate 4, causing the tension spring 8 to undergo elastic deformation and perform energy storage operation. By supplying power to the electromagnet 22, the side of the electromagnet 22 close to the magnetic block 23 is magnetized. The sides of the electromagnet 22 and the magnetic block 23 that are close to each other are of the same polarity. According to the principle of like poles repulsion, the magnetic block 23 is pushed away from the electromagnet 22, thereby causing the slider 18 to move in the slide groove 17. The insertion plate 19 on one side of the slider 18 is inserted into the limiting blade 16 to limit the limiting blade 16 and prevent the limiting blade 16 from rotating.
[0036] By limiting the limit blade 16, the stop bar 13 on the other side is limited, thereby limiting the cutting plate 4 through the fixed shaft 10, preventing the cutting plate 4 from rotating during use. When the cutting operation is required, the electromagnet 22 is de-energized, and the side of the electromagnet 22 near the magnetic block 23 no longer generates magnetism, so that the magnetic block 23 on one side is no longer pushed. At this time, the tension spring 8 will pull the cutting plate 4 and its pin 3 to rotate in opposite directions, driving the fixed shaft 10 to rotate synchronously. The fixed shaft 10 drives the stop bar 13 on one side to rotate synchronously. At this time, the limit blade 16 can rotate freely, allowing the stop bar 13 to rotate freely without being resisted by the limit blade 16, so that the cutting plate 4 can complete the cutting operation. Through the synchronizing rod 9, the three cutting plates 4 can be kept rotating synchronously, and the cutting can be carried out smoothly.
[0037] The present invention has the following technical effects.
[0038] 1. This utility model uses a guide plate 5, a lifting ring 6, a fixing rod 7, and a tension spring 8 to pre-store energy in the non-working state of the cutting plate 4, so that it can respond quickly and complete the cutting operation when cutting is required later. The fixing ring 12, the stop rod 13, and the limiting blade 16 reliably limit the fixed shaft 10, ensuring that the cutting plate 4 remains stable in the non-operation stage until the cutting command is received.
[0039] 2. This utility model achieves controllable limiting of the limiting blade 16 through electromagnet 22, magnetic block 23 and insert plate 19, so that it can flexibly switch the locking and releasing of the stop bar 13 according to the actual signal. Through slider 18, limiting groove 20 and limiting block 21, the moving path of insert plate 19 is precisely guided and limited, ensuring that the entire limiting mechanism moves accurately and responds in a timely manner, further improving the reliability and response efficiency of the overall control.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
