Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and in particular to a mechanism system with remote tripping. Background Technology

[0002] Disconnecting switches are mainly used for scenarios involving power isolation, switching operations, and connecting and disconnecting low-current circuits, providing effective protection for lines and electrical equipment. To enhance the intelligence of disconnecting switches, those with remote tripping capabilities have gradually emerged, allowing them to trip and open based on control commands from a remote terminal. However, existing disconnecting switches with remote tripping capabilities have limited opening torque and generally poor arc-extinguishing capabilities. Utility Model Content

[0025] Please see Figures 1 to 6 As shown, the mechanism system with remote release in this embodiment includes an upper cover 1, a middle platform 14 and a base 19. The lower cover 1 is provided with a lower pad 8, a plug 13, a spring base 19 and a lower platform 18 in sequence below it. The upper cover 1, the lower pad 8, the plug 13, the spring base 19 and the lower platform 18 are all provided with circular channels. The circular channels in the upper cover 1, the lower pad 8, the plug 13, the spring base 19 and the lower platform 18 are all provided with a central tube 2. The top of the lower pad 8 is provided with a circular hole, and a truncated cone rod 4 is provided in the circular hole. The outer periphery of the truncated cone rod 4 is provided with an upper pad 6. The side structure of the lower pad 8 and the upper pad 6 is a protrusion. A tension spring 9 is connected between the two protrusions.

[0026] The outer periphery of the central tube 2 is also fitted with an upper spring 11 and a lower spring 15. The upper spring 11 and the lower spring 15 are respectively positioned above the plug-in 13 and the spring base 16. The top of the lower platform 18 is fitted with a spring sleeve post 17. The spring sleeve post 17 passes through the middle platform 14, the lower fitting 7 and the small spring 3. The lower fitting 7 is equipped with an upper fitting 5 for resisting the small spring 3.

[0027] The outer periphery of the plug-in 13 is fitted with a snap-fit ​​component 12. Both the snap-fit ​​component 12 and the lower fitting 7 have round holes on their sides, and a plug rod 10 is installed in both round holes.

[0028] The bottom of the lower platform 18 is fitted with a base 19.

[0029] Accessories are also installed on the side of the spring sleeve post 17.

[0030] Installation steps: Insert the lower spring 15 into the spring base 16 and place it in the corresponding position to pre-stress the lower spring 15. Then place it together into the lower platform 18. Insert the plug 13 into the lower spring 15 and the spring base 16, cover the middle platform 14 and fix it with screws. Place the small spring 3 into the corresponding hole of the lower fitting 7 and then insert it into the corresponding hole of the middle platform 14. Then place the upper spring 11 into the corresponding slot of the plug 13 and the middle platform 14. Insert the plug rod 10 into the hole of the snap-fit ​​12 and place it in the corresponding position of the middle platform 14. Then cover the upper fitting 5 and fix it with screws. Insert the round platform rod 4 into the corresponding hole of the upper washer 6 and then into the corresponding hole of the lower washer 8 and rivet it to the bottom of the lower washer 8. Hang the tension spring 9 at the corresponding positions of the upper washer 6 and the lower washer 8. Then insert the center tube 2 into the lower washer 8 and then insert it into the corresponding hole of the plug 13. Cover the upper cover 1 and fix it with screws. Finally, place the spring sleeve post 17 into the corresponding position of the base 19 and install it on the middle platform 14 and fix it with screws.

[0031] illustrate

[0032] 1. Remote Disengagement Mechanism: Manually rotating the center tube 2 clockwise causes the frustum rod 4, upper washer 6, and lower washer 8 to press the snap-fit ​​part 12 downwards. The snap-fit ​​part 12 then presses the head of the spring sleeve post 17 downwards, causing it to engage. During the rotation of the insert 13, the upper spring 11 and lower spring 15 continuously store energy. After rotating a certain angle, the lower spring 15 releases its kinetic energy, causing the spring base 16 to rotate and close the switch. The upper spring 11, by pressing, moves the lower component 7 upwards, and the small spring 3 continuously stores energy. After rotating a certain angle, the upper spring 11 no longer presses the lower component 7. At this time, the small spring 3 releases its stored energy, causing the lower component 7 to reset. After the lower component 7 resets, it locks the energy stored in the upper spring 11. By giving the spring sleeve post... 17. When the current is turned on, the internal magnet generates a reaction force, which pops up the latch 12. The latch 12 drives the lower assembly 7 to move upward, so that the small spring 3 stores energy. When the energy reaches a certain critical value, the upper spring 11 releases energy, which drives the plug 13, the lower spring 15, and the spring base 16 to rotate counterclockwise, thus opening the circuit breaker. During the opening process, the plug 13 drives the central tube 2 and the lower pad 8, and then the lower pad 8 drives the round rod 4, the upper pad 6, and the tension spring 9 to rotate counterclockwise. During the rotation, the upper pad 6 is held in place by the latch 12. At this time, the upper pad 6 rotates counterclockwise and the tension spring 9 stores energy. When the rotation reaches the critical value, the upper pad 6 is no longer held in place and the tension spring 9 releases its stored energy, causing the upper pad 6 to reset. The small spring 3 releases energy, causing the lower assembly 7 to reset.

[0033] 2. A mechanism with a larger internal rotation angle; such as... Figure 1 The two protruding positions of the lower spring 15 are locked in place by the corresponding positions of the spring base 16. At this time, the insert 13 and the spring base 16 are limited by the central platform 14, allowing them to rotate only clockwise. During the rotation, the lower spring 15 continuously stores energy. After a certain angle, the insert 13 will press the limited portion of the spring base 16 downwards, and the lower spring 15 will release energy, causing the spring base 16 to rotate a certain angle, such as... Figure 2 At this time, the plug-in 13 and the spring base 16 are limited by the middle platform 14, and the bottom can rotate to a larger angle by the angle difference between the plug-in 13 and the spring base 16.

[0034] 3. One-way locking mechanism: When the center tube 2 is rotated clockwise, the truncated cone rod 4, the upper washer 6, and the lower washer 8 will press the snap-fit ​​part 12 downward; when rotated counterclockwise, the upper washer 6 will become a movable part that can rotate counterclockwise when it encounters an obstacle, and the tension spring 9 will reset it.
