Description

Technical Field

[0001] The present invention relates to the technical field of isolating switches, and in particular to an operating mechanism for isolating switches. Background Art

[0002] The operating mechanism of the disconnector is located on the disconnector, driving the disconnector's opening and closing operations. Existing disconnectors rely entirely on bevel gear transmission, synchronizing opening and closing operations with the operating mechanism's movement. This results in the opening and closing speed being dependent on the operating mechanism's movement speed, potentially leading to prolonged arcing and the risk of burnout. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide an operating mechanism for an isolating switch. The operating mechanism consists of an active module and a driven module. The active module and the driven module each have an energy storage process and a limit. During the movement, the handle directly acts on the active module. The active module can push the execution module to move, but the driven module does not drive the active module. The two sets of modules are not completely locked during the opening and closing movement, so that the operating speed of the personnel is unrelated to the movement speed of the module, thereby realizing rapid opening and closing of the contacts, shortening the existence time of the arc, and greatly improving the safety of the switch; the rotation angle of the operating mechanism reaches 90°, so that the contacts have a larger opening and closing angle, further reducing the impact of the arc on the switch during opening and closing; the operating mechanism can be operated from the top and side, making the operation method more diversified and suitable for different installation scenarios.

[0014] Here's how it works: In the present invention, the operating mechanism includes an active module and a passive module.

[0015] The first bracket, the first spring, the first gear, the second gear, the first shaft and the second shaft constitute the active module; the third shaft, the splint, the retaining ring, the bushing, the amplifying rod, the slider, the slide bar, the rocker bar, the gasket, the second spring, the fourth shaft, the sixth shaft, the fifth shaft, the crank, the synchronization rod and the seventh shaft constitute the driven module.

[0016] When the switch is closed, the first gear rotates clockwise, and the first side plate also begins to move clockwise. When the first side plate rotates to a certain angle around the second hole, one end of the tenth slot on the first side plate contacts the slide bar, pushing the slide bar around the third axis. The slide bar then drives the clamping plate clockwise around the third axis. Simultaneously, the slide bar moves downward along the sixteenth slot, driving the rocker arm counterclockwise around the seventh axis. During this process, the slide bar and clamping plate push the washer downward, compressing the second spring.

[0017] Furthermore, the slide rod moves in the nineteenth slot, driving the amplifying rod to move clockwise around the sixth axis. The amplifying rod, the crank, and the synchronizing rod form a connecting rod mechanism. The amplifying rod's rotational center is lower than the plate's, thereby amplifying the plate's rotational angle: the plate's rotational angle is 90°, while the amplifying rod's rotational angle is 180°. The fourth axis slides in the fourteenth slot of the slide rod.

[0018] Before the slave module passes dead center, the slider does not move because the fourth shaft moves in the fourteenth slot. When the two-link module, consisting of a clamping plate and a rocker arm, passes dead center (the clamping plate and the rocker arm are aligned), the second spring releases, the slide bar disengages from the first side plate, and the second spring drives the slave module. The fourth shaft contacts the slider, and the movement of the amplifying rod is transmitted 1:1 to the slider, causing the slider to rotate clockwise. When the twenty-first boss contacts the fifth boss, the slave module reaches the closed position, and movement stops. The master module, driven by the first spring, reaches the closed position when the eleventh slot contacts the seventh boss, and movement stops.

[0019] When the switch opens, the first gear rotates counterclockwise, and the first side plate also begins to move counterclockwise. When the first side plate rotates to a certain angle around the second hole, one end of the tenth slot on the first side plate contacts the slide bar, pushing the slide bar around the third axis. The slide bar then drives the clamping plate counterclockwise around the third axis. Simultaneously, the slide bar moves downward along the sixteenth slot, driving the rocker arm clockwise around the seventh axis. During this process, the slide bar and clamping plate push the gasket downward, compressing the second spring.

[0020] Furthermore, the slide rod moves within the nineteenth slot, driving the amplifying rod to move counterclockwise around the sixth axis. When the two-link module, consisting of the clamp and rocker, passes through its dead center (the clamp and rocker are aligned), the second spring releases, the slide rod disengages from the first side plate, and the second spring drives the follower module to move. The fourth axis contacts the slider, and the movement of the amplifying rod is transmitted to the slider, driving it to rotate counterclockwise. When the twenty-first boss contacts the fifth boss, the follower module reaches the closed position, and movement ceases. The active module, driven by the first spring, reaches the closed position when it rotates to the eleventh slot and contacts the seventh boss, and movement ceases.

[0021] The second bracket is held together by the sixth boss, the outer wall of the first slot, and the inner walls of the first and second housings. A screw can be inserted through the contact module and engage the seventeenth hole to mount the contact module. Both the twentieth and eighteenth slots can accommodate handles, allowing for opening and closing operations from both the top and side of the operating module.

[0022] Compared with the prior art, the present invention has the following advantages: (1) The operating mechanism consists of an active module and a passive module. The active module and the passive module each have an energy storage process and a limit. During the movement, the handle directly acts on the active module. The active module can push the execution module to move, but the passive module does not drive the active module. The two sets of modules are not completely locked during the opening and closing movement, so that the operating speed of the personnel is independent of the movement speed of the modules, achieving rapid opening and closing of the contacts, shortening the arc existence time, and greatly improving the safety of the switch.

[0023] (2) The rotation angle of the operating mechanism reaches 90°, which enables the contacts to have a larger opening and closing angle, further reducing the impact of the arc on the switch during opening and closing.

[0024] (3) The operating mechanism can be operated from both the top and the side, making the operation more diversified and suitable for different installation scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Here's how it works: In the present invention, the operating mechanism includes an active module and a passive module.

[0039] The first bracket 3, the first spring 4, the first gear 5, the second gear 6, the first shaft 9 and the second shaft 10 constitute the active module; the third shaft 11, the splint 12, the retaining ring 13, the sleeve 14, the amplifying rod 15, the slider 16, the slide bar 17, the rocker rod 18, the gasket 19, the second spring 20, the fourth shaft 21, the sixth shaft 22, the fifth shaft 23, the crank 24, the synchronization rod 25, and the seventh shaft 26 constitute the driven module.

[0040] like Figure 32 As shown, when the switch is initially closed, the first gear 5 rotates clockwise, and the first side plate 7 also begins to move clockwise. When the first side plate 7 rotates to a certain angle around the second hole 1d, one end of the tenth slot 7a on the first side plate 7 contacts the slide bar 17, pushing the slide bar 17 around the third axis 11. The slide bar 17 then drives the clamping plate 12 clockwise around the third axis 11. Simultaneously, the slide bar 17 moves downward along the sixteenth slot 18c, driving the rocker 18 counterclockwise around the seventh axis 26. During this process, the slide bar 17 and clamping plate 12 push the washer 19 downward, compressing the second spring 20.

[0041] Furthermore, the slide bar 17 moves within the nineteenth slot 15b, driving the amplifying rod 15 to move clockwise about the sixth axis 22. The amplifying rod 15, crank 24, and synchronizing rod 25 form a linkage mechanism. The amplifying rod 15's rotational center is lower than that of the clamping plate 12, thereby amplifying the clamping plate 12's rotational angle. The clamping plate's rotational angle is 90°, while the amplifying rod's rotational angle is 180°. The fourth axis 21 slides within the fourteenth slot 16a of the slide bar 16.

[0042] Before the driven module passes the dead point, the slider 16 does not move because the fourth shaft 21 moves in the fourteenth slot 16a. Figure 31 As shown, when the two-link module consisting of the clamping plate 12 and the rocker 18 passes through its dead point (where the clamping plate 12 and the rocker 18 are aligned), the second spring 20 releases, the slide bar 17 disengages from the first side plate 7, and the second spring 20 drives the follower module to move. The fourth shaft 21 contacts the slider 16, and the movement of the amplifying rod 15 is transmitted 1:1 to the slider 16, thereby driving the slider 16 to rotate clockwise. When the 21st boss 16d contacts the 5th boss 1i, the follower module reaches the closed position and stops moving. The active module, driven by the first spring 4, reaches the closed position and stops moving when the 11th slot 8a contacts the 7th boss 1k.

[0043] like Figure 30As shown, when the brake is initially opened, the first gear 5 rotates counterclockwise, and the first side plate 7 also begins to move counterclockwise. When the first side plate 7 rotates to a certain angle around the second hole 1d, one end of the tenth slot 7a on the first side plate 7 contacts the slide bar 17, pushing the slide bar 17 around the third axis 11. The slide bar 17 then drives the clamping plate 12 counterclockwise around the third axis 11. Simultaneously, the slide bar 17 moves downward along the sixteenth slot 18c, driving the rocker arm 18 clockwise around the seventh axis 26. During this process, the slide bar 17 and clamping plate 12 push the washer 19 downward, compressing the second spring 20.

[0044] In addition, the slide bar 17 moves in the nineteenth slot 15b, driving the amplifying rod 15 to move counterclockwise around the sixth axis 22. When the two-link module consisting of the clamping plate 12 and the rocker 18 passes the dead point (the clamping plate 12 and the rocker 18 are located on the same straight line), the second spring 20 is released, the slide bar 17 disengages from the first side plate 7, the second spring 20 drives the follower module to move, and the fourth axis 21 contacts the slider 16. The movement of the amplifying rod 15 can be transmitted to the slider 16 at a 1:1 ratio, thereby driving the slider 16 to rotate counterclockwise. When the twenty-first boss 16d contacts the fifth boss 1i, the follower module reaches the closed position and movement stops. The active module, driven by the first spring 4, reaches the closed position when it rotates to the eleventh slot 8a and contacts the seventh boss 1k, and the active module reaches the closed position and movement stops.

[0045] The second bracket 27 is held together by the sixth boss 1j, the outer wall of the first slot 1b, and the inner walls of the first and second housings 1 and 2. Screws can be inserted through the contact module and engage with the seventeenth hole 27a to secure the contact module. Both the twentieth slot 5c and the eighteenth slot 6b can accommodate handles, allowing for opening and closing operations from both the top and side of the operating module.
