Description

Technical Field

[0001] This invention relates to the field of outdoor vacuum circuit breaker technology, and more specifically, to a high-safety-performance outdoor vacuum circuit breaker and its usage method. Background Technology

[0002] Outdoor vacuum circuit breakers play an important role in power transmission and distribution lines. They typically consist of two main parts: the circuit breaker and the disconnecting switch. The core of the circuit breaker is the vacuum interrupter, which contains stationary and moving contacts that control the opening and closing of the circuit. The opening and closing of the circuit breaker (which is essentially the vacuum interrupter) is controlled by the circuit breaker operating mechanism. The disconnecting switch is used to establish a reliable insulation gap, separating the line with a clear disconnection point to ensure the safety of operators and equipment. The opening and closing of the disconnecting switch is controlled by the disconnecting operating mechanism.

[0003] Currently, existing outdoor vacuum circuit breakers have the following drawbacks when reused:

[0004] (1) In the prior art, outdoor vacuum circuit breakers are generally installed at a height. When closing the circuit, operators need to climb to a high place to store energy, which makes opening and closing inconvenient and the safety is poor. At the same time, the use of springs for energy storage is easy to be damaged, the service life is short, and the opening and closing effect is poor.

[0005] (2) In the prior art, secondary power disconnection is achieved by isolating knife switch, but after long-term use, gaps are likely to appear between the knife seat and the switch plate, resulting in poor contact.

[0006] Therefore, we have made improvements to this and proposed a high-safety outdoor vacuum circuit breaker and its usage method. Summary of the Invention

[0018] As a preferred technical solution of the present invention, a controller and a wireless signal transmission module are fixedly connected inside the box, and the controller and the wireless signal transmission module are electrically connected.

[0019] As a preferred technical solution of the present invention, a limiting plate is fixedly connected to the transmission tube, and a limiting post that cooperates with the limiting plate is fixedly connected to the side wall of the housing near the transmission tube. Openings that cooperate with the spline shaft are opened in the first mounting tube, the second mounting tube and the transmission tube.

[0020] This invention also provides a method for using a high-safety outdoor vacuum circuit breaker, comprising the following steps:

[0021] S1: Energy storage. The first motor drives the drive gear to rotate, which in turn drives the driven gear and the transmission tube to rotate, so that the spring is wound up and stores energy. At the same time, the rotation of the transmission tube will drive the ratchet and the limit plate to rotate synchronously. When the limit plate rotates and abuts against the limit post, energy storage stops. At this time, the pawl limits the ratchet.

[0022] S2: When the circuit breaker is closed, the second motor drives the first connecting shaft to rotate. The rotation of the first connecting shaft drives the toggle block to rotate, which in turn drives the toggle pin to move. The movement of the toggle pin causes the moving seat to slide along the guide rod. The sliding of the moving seat causes the disc to move, which in turn causes the spline shaft to move synchronously. The spline shaft moves and inserts into the transmission tube. At this time, the spline shaft is positioned in the first mounting tube, the second mounting tube, and the transmission tube. Simultaneously, the rotation of the first connecting shaft drives the first bevel gear to rotate synchronously. The rotation of the first bevel gear drives the second bevel gear to rotate, which in turn drives the transmission shaft to rotate. The rotation of the transmission shaft drives the third bevel gear to rotate, and the rotation of the third bevel gear drives the fourth bevel gear to rotate. The rotation of the fourth bevel gear drives the second connecting shaft to rotate, which in turn drives the rotating plate to rotate. The rotation of the rotating plate drives the connecting plate to move, which in turn drives the pulling block to move downward. The downward movement of the pulling block drives the connecting column to move downward, which in turn causes the pawl to rotate, thereby releasing the limiting effect on the ratchet. Then, the electric telescopic rod shortens, pushes the block to retract, and releases the limiting effect on the assembly frame. The spring releases energy, driving the transmission tube to rotate. The rotation of the transmission tube drives the spline shaft to rotate, which in turn drives the second mounting tube and the first mounting tube to rotate, which in turn drives the rotating seat to rotate. The rotation of the rotating seat drives the connecting seat to rotate, which in turn drives the moving column to move. The moving column drives the moving contact to move upward and contact the stationary contact, thus achieving the opening of the circuit breaker.

[0023] S3: When the circuit breaker is opened, the drive docking linkage mechanism is reset, the spline shaft is separated from the transmission tube, and then the pawl is reset to limit the ratchet again. Then the electric telescopic rod is extended, causing the push block to move. The movement of the push block drives the extension column to move, and the movement of the extension column drives the assembly frame to move, thereby causing the mating frame to move. This causes the first mounting tube and the second mounting tube to rotate in opposite directions, thereby causing the contact to separate from the stationary contact and realizing the circuit breaker opening operation.

[0024] S4: Isolation and separation. The hook component is used to rotate the handle, which drives the isolation shaft to rotate. The rotation of the isolation shaft in turn drives the base plate to rotate. The rotation of the base plate causes the isolation lever to move. The movement of the isolation lever drives the isolation tool holder to rotate, which in turn causes the tool holder to rotate. The rotation of the isolation shaft drives the assembly piece to rotate synchronously, thereby causing the mounting head and connecting column to move. Combined with the elasticity of the first spring, the isolation tool holder and tool holder open and close.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In the solution of this invention:

[0027] 1. By setting up a first mounting pipe, a second mounting pipe, a transmission pipe, an energy storage mechanism, a limit mechanism, a closing and opening mechanism, and a docking linkage mechanism, it realizes automated energy storage before closing. Energy storage by spring is not easily deformed, which improves service life. It can also automatically open and close, improve the convenience of opening and closing of vacuum circuit breakers, enhance safety, and significantly improve the opening and closing effect. It solves the problems of inconvenience in automatic energy storage and poor opening and closing effect in the existing technology.

[0028] 2. By using the connecting piece, the switch piece, the center plate, the guide post, and the second spring, the second spring ensures that the switch piece and the knife holder are in close contact, guaranteeing good conductivity, improving the safety and reliability of the circuit breaker, avoiding poor contact after long-term use, and solving the problem of poor contact caused by gaps between the knife holder and the switch piece in the prior art.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] like Figures 1-12As shown, this embodiment proposes a high-safety outdoor vacuum circuit breaker, including a housing 1. Three insulating cylinders 2 are uniformly fixedly connected to the upper surface of the housing 1. Two first mounting plates 3 are symmetrically and fixedly connected inside the housing 1, and a first mounting tube 4 is rotatably connected between the two first mounting plates 3. Two second mounting plates 5 are also fixedly connected inside the housing 1, and a second mounting tube 6 is rotatably connected between the two second mounting plates 5. Rotary seats 7 corresponding to the insulating cylinders 2 are fixedly connected to the first mounting tube 4 and the second mounting tube 6, respectively. A connecting seat 8 is rotatably connected to the top of each rotary seat 7. An arc-extinguishing chamber 9 is fixedly connected to each of the three insulating cylinders 2. A movable column 10 is slidably connected to the bottom of each arc-extinguishing chamber 9. The bottom of the movable column 10 penetrates the upper surface of the housing 1 and is rotatably connected to the connecting seat 8. A moving contact 11 is fixed to the top of the movable column 10. A terminal post 12 is fixed to the top of each insulating cylinder 2. The bottom of the terminal post 12 penetrates the top of the arc-extinguishing chamber 9 and is fixed with a... The stationary contact 13 and the bottom of the moving column 10 are equipped with a telescopic sleeve 14. A transmission pipe 15 is rotatably connected to the side wall of the housing 1 near the second mounting pipe 6. The transmission pipe 15 is equipped with an energy storage mechanism 16 and a limit mechanism 17. The first mounting pipe 4 is equipped with a circuit breaking and closing mechanism 18. The housing 1 is equipped with a docking linkage mechanism 19. The docking linkage mechanism 19 enables the transmission pipe 15 to dock with the second mounting pipe 6 and the first mounting pipe 4. The rotation of the transmission pipe 15 drives the second mounting pipe 6 and the first mounting pipe 4 to rotate. The rotation of the first mounting pipe 4 and the second mounting pipe 6 drives the rotating seat 7 to rotate. The rotation of the rotating seat 7 drives the connecting seat 8 to rotate. The rotation of the connecting seat 8 drives the moving column 10 to move. The moving column 10 drives the moving contact 11 to move upward and contact the stationary contact 13 to achieve circuit conduction. When the circuit is opened, the moving contact 11 separates from the stationary contact 13 and generates an electric arc. The arc extinguishing chamber 9 can quickly extinguish the electric arc to prevent the electric arc from damaging the equipment.

[0045] like Figure 2 , Figure 7 and Figure 8As shown, in a preferred embodiment, based on the above method, the energy storage mechanism 16 further includes a fixed base 1601 disposed outside the transmission tube 15, a mounting plate 1602 fixedly connected inside the fixed base 1601, a spring 1603 disposed inside the mounting plate 1602, the inner end of the spring 1603 being fixedly connected to the outer peripheral sidewall of the transmission tube 15, and the other end of the spring 1603 being fixedly connected to a fixed tube 1604, the fixed tube 1604 being rotatably connected to the mounting plate 1602 via a pin, a driven gear 1605 being fixedly connected to the transmission tube 15, and a fixed gear 1605 being fixed inside the housing 1. A support base 1606 is connected, and a first motor 1607 is fixedly connected to the support base 1606. The drive end of the first motor 1607 passes through the side wall of the support base 1606 and is fixedly connected to a drive gear 1608 that meshes with the driven gear 1605. The first motor 1607 drives the drive gear 1608 to rotate, which in turn drives the driven gear 1605 and the transmission tube 15 to rotate, causing the spring 1603 to wind up and store energy. When closing is required, the spring 1603 releases energy, driving the transmission tube 15 to rotate, providing power for the closing operation, and improving the reliability and safety of the circuit breaker.

[0046] like Figure 2 , Figure 7 and Figure 9 As shown, in a preferred embodiment, based on the above method, the limiting mechanism 17 further includes a ratchet 1701 fixed on the transmission tube 15, and a side shaft 1702 rotatably connected to the side wall of the housing 1 near the ratchet 1701. A pawl 1703 is fixedly connected to the outer end of the side shaft 1702. The ratchet 1701 and the pawl 1703 cooperate so that when the transmission tube 15 rotates to a certain position, the pawl 1703 locks the ratchet 1701 to prevent the transmission tube 15 from reversing and to ensure the stability of the closing operation.

[0047] like Figure 2 , Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the opening and closing mechanism 18 further includes a bottom frame 1801 fixed to the bottom wall of the housing 1. An assembly frame 1802 is slidably connected inside the bottom frame 1801. A mating frame 1803 is rotatably connected to the top of the assembly frame 1802. The mating frame 1803 is fixedly connected to the first mounting tube 4. An extension column 1804 is fixedly connected to one end of the assembly frame 1802. A horizontal plate 1805 is fixedly connected to the side wall of the bottom frame 1801 near the extension column 1804. An electric telescopic rod 1806 is fixedly connected to the horizontal plate 1805. A push block 1807 that cooperates with the extension column 1804 is fixedly connected to the driving end of the electric telescopic rod 1806. When... When closing is required, the electric telescopic rod 1806 shortens, the push block 1807 retracts to release the limit on the assembly frame 1802, and then the first mounting tube 4 is rotated through the cooperating frame 1803, thereby realizing the closing operation of the circuit breaker. When opening, the electric telescopic rod 1806 extends, causing the push block 1807 to move. The movement of the push block 1807 drives the extension column 1804 to move, and the movement of the extension column 1804 drives the assembly frame 1802 to move, thereby causing the cooperating frame 1803 to move, which in turn causes the first mounting tube 4 to rotate, thereby causing the contact 11 to separate from the stationary contact 13, realizing the opening operation. The operation is convenient and precise, and the opening and closing actions can be completed quickly, improving the response speed and reliability of the circuit breaker.

[0048] like Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, in a preferred embodiment, based on the above method, the docking linkage mechanism 19 further includes a spline shaft 1901 slidably disposed between the first mounting tube 4 and the second mounting tube 6. A disc 1902 is fixedly connected to the spline shaft 1901. A movable seat 1903 is rotatably connected to the bottom of the disc 1902. Two guide rods 1904 are slidably connected to the bottom of the movable seat 1903. The left and right ends of the two guide rods 1904 are fixedly connected to the first mounting plate 3 and the second mounting plate 5, respectively. A shift post 1905 is fixedly connected to the side wall of the movable seat 1903. A shift block 1906 is provided at the outer end of the shift post 1905. A mounting frame 1907 is fixedly connected inside the housing 1. A first connecting shaft 1908 is rotatably connected to the end of the mounting frame 1907 near the shift block 1906. The end of the first connecting shaft 1908 near the shift block 1906 is fixedly connected to it. A first bevel gear 1909 is fixedly connected to the first connecting shaft 1908. A second motor 1910 is fixedly connected to the outer wall of the frame 1907 near the first connecting shaft 1908. The driving end of the second motor 1910 is fixedly connected to the other end of the first connecting shaft 1908. The second motor 1910 drives the first connecting shaft 1908 to rotate. The rotation of the first connecting shaft 1908 drives the lever 1906 to rotate. The rotation of the lever 1906 drives the lever 1905 to move. The movement of the lever 1905 causes the moving seat 1903 to slide along the guide rod 1904. The sliding of the moving seat 1903 drives the disc 1902 to move. The movement of the disc 1902 drives the spline shaft 1901 to move synchronously. The movement of the spline shaft 1901 inserts into the transmission tube 15. Thus, when the energy is stored and released, the transmission tube 15 can drive the first mounting tube 4 and the second mounting tube 6 to rotate synchronously. The rotation of the first connecting shaft 1908 will drive the first bevel gear 1909 to rotate synchronously.

[0049] like Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, in a preferred embodiment, based on the above method, two connecting ears 1911 are symmetrically and fixedly connected to the inner sidewall of the mounting frame 1907. A drive shaft 1912 is rotatably connected between the two connecting ears 1911. One end of the drive shaft 1912 is fixedly connected to a second bevel gear 1913 that meshes with the first bevel gear 1909, and the other end of the drive shaft 1912 is fixedly connected to a third bevel gear 1914. A second connecting shaft 1915 is rotatably connected to the other end of the mounting frame 1907. A fourth bevel gear 1916 that meshes with the third bevel gear 1914 is fixedly connected to the second connecting shaft 1915. A rotating plate 1917 is rotatably connected to the outer end of the second connecting shaft 1915. A connecting plate 1918 is rotatably connected to the top end of the rotating plate 1917. A pulling block 1919 is rotatably connected to the top end of the connecting plate 1918. A connecting post 1920 is provided inside the pulling block 1919. The connecting post 1920 and... The pawl 1703 is fixedly connected, and the guide sleeve 1921 is slidably connected to the pull block 1919. The guide sleeve 1921 is fixedly connected to the inner side wall of the housing 1. The rotation of the first bevel gear 1909 will drive the second bevel gear 1913 to rotate. The rotation of the second bevel gear 1913 will drive the transmission shaft 1912 to rotate. The rotation of the transmission shaft 1912 will drive the third bevel gear 1914 to rotate. The rotation of the third bevel gear 1914 will drive the fourth bevel gear 1916 to rotate. The rotation of the fourth bevel gear 1916 will drive the second connecting shaft 1915 to rotate. The rotation of the second connecting shaft 1915 will drive the rotating plate 1917 to rotate. The rotation of the rotating plate 1917 will drive the connecting plate 1918 to move. The connecting plate 1918 will drive the pull block 1919 to move downward. The downward movement of the pull block 1919 will drive the connecting column 1920 to move downward, thereby causing the pawl 1703 to rotate, thus releasing the limiting effect on the ratchet 1701.

[0050] like Figure 1 , Figure 3 and Figure 10As shown, in a preferred embodiment, based on the above method, a side frame 20 is fixedly connected to the outer wall of the housing 1, and current transformers 21 are fixedly installed on the three insulating cylinders 2. An isolating blade holder 22 is rotatably connected to the outer end of the current transformer 21, and an isolating pull rod 23 is rotatably connected inside the isolating blade holder 22. A base plate 24 is rotatably connected to the bottom end of the isolating pull rod 23, and an isolating shaft 25 is fixedly connected between the base plates 24. The isolating shaft 25 is rotatably connected to the side frame 20, and a handle 26 is fixedly connected to the outer end of the isolating shaft 25. Two assembly pieces 27 are symmetrically and fixedly connected to the isolating shaft 25. The end of the assembly piece 27 is rotatably connected to the mounting head 28, and the end of the mounting head 28 is fixedly connected to the connecting post 29. The outer end of the connecting post 29 penetrates the side wall of the side frame 20 and extends to the outside. The outer end of the connecting post 29 is fixedly connected to the connecting piece 30. A first spring 31 is sleeved on the connecting post 29. The two ends of the first spring 31 are fixedly connected to the side frame 20 and the mounting head 28, respectively. Three insulators 32 are fixedly connected to the upper end face of the front end of the side frame 20. A knife holder 33 is installed at the bottom end of the isolation rod 23. A terminal piece 34 is fixedly connected to the top of each insulator 32. Two terminal pieces 34 are symmetrically arranged on the terminal piece 34. A center plate 36 is fixedly connected to the center of the upper end face of the brake plate 35 and the connecting piece 34.

The knife holder 33 cooperates with the brake plate 35 on the connecting piece 34 to achieve circuit isolation. The second spring 38 ensures a tight fit between the brake plate 35 and the knife holder 33. Contact is made to ensure good conductivity and improve the safety and reliability of the circuit breaker. By turning the handle 26, the isolating shaft 25 is rotated. The rotation of the isolating shaft 25 drives the base plate 24 to rotate. The rotation of the base plate 24 causes the isolating pull rod 23 to move. The movement of the isolating pull rod 23 drives the isolating knife holder 22 to rotate, which in turn causes the knife holder 33 to rotate. The rotation of the isolating shaft 25 drives the assembly plate 27 to rotate synchronously, thereby causing the mounting head 28 and the connecting column 29 to move. Combined with the elastic action of the first spring 31, the isolating knife holder 22 and the knife holder 33 open and close.

[0051] like Figure 2 and Figure 11 As shown, in a preferred embodiment, based on the above method, a controller 39 and a wireless signal transmission module 40 are fixedly connected inside the housing 1, and the controller 39 and the wireless signal transmission module 40 are electrically connected; the wireless signal transmission module 40 can realize remote opening and closing operations without requiring operators to climb to heights, thus improving safety.

[0052] like Figure 5and Figure 11 As shown, in a preferred embodiment, based on the above method, a limiting plate 41 is fixedly connected to the transmission tube 15, and a limiting post 42 that cooperates with the limiting plate 41 is fixedly connected to the side wall of the housing 1 near the transmission tube 15. Openings that cooperate with the spline shaft 1901 are opened in the first mounting tube 4, the second mounting tube 6, and the transmission tube 15. The limiting plate 41 and the limiting post 42 can provide a limit for energy storage, and the openings allow the spline shaft 1901 to slide in these tubes, realizing the power transmission and linkage between the components, ensuring the normal operation of the docking linkage mechanism 19, and improving the coordination and accuracy of the circuit breaker operation.

[0053] Specifically, in use, this high-safety outdoor vacuum circuit breaker operates as follows: First, the first motor 1607 drives the drive gear 1608 to rotate, which in turn drives the driven gear 1605 and the transmission tube 15 to rotate, causing the spring 1603 to wind and store energy. Simultaneously, the rotation of the transmission tube 15 drives the ratchet 1701 and the limiting plate 41 to rotate synchronously. When the limiting plate 41 rotates and abuts against the limiting post 42, energy storage stops. At this time, the pawl 1703 limits the ratchet 1701. Then, the second motor 1910 drives the first connecting shaft 1908 to rotate. The rotation of the first connecting shaft 1908 drives the lever 1906 to rotate. The rotation of the lever 1906 drives the shift post 1905 to move. The movement of the shift post 1905 causes the moving seat 1903 to move along the guide rod 190... 4. Sliding: The sliding of the movable seat 1903 drives the disk 1902 to move, and the movement of the disk 1902 drives the spline shaft 1901 to move synchronously. The spline shaft 1901 is inserted into the transmission tube 15. At this time, the spline shaft 1901 is placed in the first mounting tube 4, the second mounting tube 6, and the transmission tube 15. Simultaneously, the rotation of the first connecting shaft 1908 drives the first bevel gear 1909 to rotate synchronously. The rotation of the first bevel gear 1909 drives the second bevel gear 1913 to rotate. The rotation of the second bevel gear 1913 drives the transmission shaft 1912 to rotate. The rotation of the transmission shaft 1912 drives the third bevel gear 1914 to rotate. The rotation of the third bevel gear 1914 drives the fourth bevel gear 1916 to rotate. The rotation of the fourth bevel gear 1916 drives the second connecting shaft 1915 to rotate, which in turn drives the rotating plate 1917 to rotate. The rotation of the rotating plate 1917 drives the connecting plate 1918 to move, which in turn drives the pulling block 1919 to move downward. The downward movement of the pulling block 1919 drives the connecting column 1920 to move downward, thereby causing the pawl 1703 to rotate, thus releasing the limiting effect on the ratchet 1701. Then, the electric telescopic rod 1806 shortens, pushing the block 1807 to retract and release the limiting effect on the assembly frame 1802. The spring 1603 releases energy, driving the transmission tube 15 to rotate. The rotation of the transmission tube 15 drives the spline shaft 1901 to rotate, thereby causing the second mounting tube 6 and the first mounting tube to move downward. Rotation 4 causes the rotating seat 7 to rotate, which in turn causes the connecting seat 8 to rotate. The rotation of the connecting seat 8 causes the moving column 10 to move, which in turn causes the moving contact 11 to move upward and contact the stationary contact 13, thus opening the circuit breaker. This drives the docking linkage mechanism 19 to reset, causing the spline shaft 1901 to separate from the transmission tube 15. Then, the pawl 1703 resets and limits the ratchet 1701 again. Then, the electric telescopic rod 1806 extends, causing the push block 1807 to move. The movement of the push block 1807 causes the extension column 1804 to move, which in turn causes the assembly frame 1802 to move, thereby causing the mating frame 1803 to move. This, in turn, causes the first mounting tube 4 and the second mounting tube 6 to rotate in opposite directions.This causes contact 11 to separate from stationary contact 13, achieving the tripping operation. During secondary separation, the hook component rotates handle 26, which in turn rotates isolating shaft 25. The rotation of isolating shaft 25, in turn, rotates base plate 24. The rotation of base plate 24 causes isolating lever 23 to move, which in turn rotates isolating knife holder 22, which in turn rotates knife holder 33. The rotation of isolating shaft 25 then causes assembly plate 27 to rotate synchronously, thereby moving mounting head 28 and connecting post 29. Combined with the elasticity of the first spring 31, this causes isolating knife holder 22 and knife holder 33 to open and close.

Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.

10. A method of using a high-safety outdoor vacuum circuit breaker according to any one of claims 1-9, characterized in that, Includes the following steps: S1: Energy storage. The first motor drives the drive gear to rotate, which in turn drives the driven gear and the transmission tube to rotate, so that the spring is wound up and stores energy. At the same time, the rotation of the transmission tube will drive the ratchet and the limit plate to rotate synchronously. When the limit plate rotates and abuts against the limit post, energy storage stops. At this time, the pawl limits the ratchet. S2: When the circuit breaker is closed, the second motor drives the first connecting shaft to rotate. The rotation of the first connecting shaft drives the toggle block to rotate, which in turn drives the toggle pin to move. The movement of the toggle pin causes the moving seat to slide along the guide rod. The sliding of the moving seat causes the disc to move, which in turn causes the spline shaft to move synchronously. The spline shaft moves and inserts into the transmission tube. At this time, the spline shaft is positioned in the first mounting tube, the second mounting tube, and the transmission tube. Simultaneously, the rotation of the first connecting shaft drives the first bevel gear to rotate synchronously. The rotation of the first bevel gear drives the second bevel gear to rotate, which in turn drives the transmission shaft to rotate. The rotation of the transmission shaft drives the third bevel gear to rotate, and the rotation of the third bevel gear drives the fourth bevel gear to rotate. The rotation of the fourth bevel gear drives the second connecting shaft to rotate, which in turn drives the rotating plate to rotate. The rotation of the rotating plate drives the connecting plate to move, which in turn drives the pulling block to move downward. The downward movement of the pulling block drives the connecting column to move downward, which in turn causes the pawl to rotate, thereby releasing the limiting effect on the ratchet. Then, the electric telescopic rod shortens, pushes the block to retract, and releases the limiting effect on the assembly frame. The spring releases energy, driving the transmission tube to rotate. The rotation of the transmission tube drives the spline shaft to rotate, which in turn drives the second mounting tube and the first mounting tube to rotate, which in turn drives the rotating seat to rotate. The rotation of the rotating seat drives the connecting seat to rotate, which in turn drives the moving column to move. The moving column drives the moving contact to move upward and contact the stationary contact, thus achieving the opening of the circuit breaker. S3: When the circuit breaker is opened, the drive docking linkage mechanism is reset, the spline shaft is separated from the transmission tube, and then the pawl is reset to limit the ratchet again. Then the electric telescopic rod is extended, causing the push block to move. The movement of the push block drives the extension column to move, and the movement of the extension column drives the assembly frame to move, thereby causing the mating frame to move. This causes the first mounting tube and the second mounting tube to rotate in opposite directions, thereby causing the contact to separate from the stationary contact and realizing the circuit breaker opening operation. S4: Isolation and separation. The hook component is used to rotate the handle, which drives the isolation shaft to rotate. The rotation of the isolation shaft in turn drives the base plate to rotate. The rotation of the base plate causes the isolation lever to move. The movement of the isolation lever drives the isolation tool holder to rotate, which in turn causes the tool holder to rotate. The rotation of the isolation shaft drives the assembly piece to rotate synchronously, thereby causing the mounting head and connecting column to move. Combined with the elasticity of the first spring, the isolation tool holder and tool holder open and close.
