Description

Technical Field

[0001] This utility model relates to the field of phase partition technology, specifically to a phase partition structure for a circuit breaker. Background Technology

[0002] The phase-block spacer of a circuit breaker is a critical insulation barrier. Its main purpose is to ensure reliable electrical isolation between the phases of the circuit breaker, prevent phase-to-phase short circuits, and ensure safe and reliable operation of the circuit breaker when interrupting large currents (generating arcs) and withstanding system voltage. During use, the phase-block spacer is installed by inserting it into the connection slot of the circuit breaker. However, existing circuit breaker phase-block spacers have relatively simple structures, usually simple plate-like structures, which are prone to detachment after insertion, resulting in poor installation stability. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a circuit breaker phase partition structure that can further improve the stability of phase partition installation and greatly reduce safety hazards.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a phase partition structure for a circuit breaker, including a phase partition plate, a connecting plate fixedly connected to one side of the phase partition, and correspondingly arranged limiting strips fixedly connected to both sides of the connecting plate. A movable groove is provided at the end of the connecting plate away from the phase partition plate, and a connecting piece is fixedly connected to the upper end of the movable groove. A supporting swing arm is hinged to the connecting piece, and a spring swing mechanism cooperating with the supporting swing arm is provided on the connecting piece. A fixing block is slidably connected to the movable groove below the supporting swing arm, and a fixing slot cooperating with the supporting swing arm is provided at the upper end of the fixing block. An adjustment slot is provided at the upper end of the connecting plate on one side of the movable groove, and an adjustment hole communicating with the adjustment slot is provided on one side of the movable groove. An adjustment block is fixedly connected to the fixed block and slidably connected to the adjustment hole. An adjustment rod is slidably inserted into the adjustment slot, and the adjustment block is fixedly connected to the side wall of the adjustment rod. A first spring is fixedly connected between the lower end of the adjustment rod and the bottom surface of the adjustment slot.

[0005] As an improvement, the elastic swing mechanism includes a gear rotatably connected to the connecting plate to drive the support swing arm to swing. The connecting plate has a control cavity, and a slider is slidably connected in the control cavity. A second spring is fixedly connected between the upper end of the control cavity and the slider. A rack extending into the control cavity and meshing with the gear is slidably connected to the connecting plate, and the upper end of the rack is fixedly connected to the slider.

[0006] As an improvement, a pressing block is fixedly connected to the upper end of the adjusting rod.

[0007] As an improvement, the pressing block is provided with a through-hole for limiting insertion, and an L-shaped limiting insert is slidably inserted into the limiting hole.

[0008] As an improvement, a limit stop is fixedly connected to the upper end of the connecting plate.

[0009] The advantages of this utility model compared with the prior art are as follows: the supporting swing arm can be initially fixed by the fixing slot on the fixing block. After the phase partition plate is connected to the circuit breaker through the connecting plug, the adjusting plug is pressed to drive the adjusting block to slide down. The adjusting block drives the fixing block to slide down, so that the lower end of the supporting swing arm is disengaged from the fixing slot. Under the restoring elastic force of the elastic swing mechanism, the supporting swing arm is pushed to swing outward and abut against the inner wall of the circuit breaker connection slot, which further improves the stability of the connection.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3As shown, a phase partition structure for a circuit breaker includes a phase partition plate 1. A connecting plate 2 is fixedly connected to one side of the phase partition plate. Limiting strips 18 are fixedly connected to both sides of the connecting plate 2. A limiting baffle 19 is fixedly connected to the upper end of the connecting plate 2. During installation, the connecting plate 2 is inserted into the connecting slot of the circuit breaker. The connecting slot is provided with a limiting slot that cooperates with the limiting strips 18. After being fully inserted, the limiting baffle 19 abuts against the upper end of the connecting slot.

[0016] The connecting plate 2 has a movable groove 3 at one end away from the partition plate 1. A connecting piece 4 is fixedly connected to the upper end of the movable groove 3. A support swing arm 5 is hinged to the connecting piece 4. The connecting piece is provided with a spring swing mechanism that cooperates with the support swing arm 5. The spring swing mechanism includes a gear 6 rotatably connected to the connecting piece to drive the support swing arm 5 to swing. The connecting plate 2 has a control cavity 20. A slider 13 is slidably connected to the control cavity 20. A second spring 15 is fixedly connected between the upper end of the control cavity 20 and the slider 13. A rack 14 extending into the control cavity 20 and meshing with the gear 6 is slidably connected to the connecting piece. The upper end of the rack 14 is fixedly connected to the slider 13.

[0017] A fixing block 7 is slidably connected to the movable groove 3 below the supporting swing arm 5. The upper end of the fixing block 7 is provided with a fixing slot 8 that cooperates with the supporting swing arm 5. The upper end of the connecting plate 2 is provided with an adjustment slot 11 located on one side of the movable groove 3. The side of the movable groove 3 is provided with an adjustment hole communicating with the adjustment slot 11. An adjustment block is fixedly connected to one side of the fixing block 7 and slidably connected to the adjustment hole. An adjustment rod 9 is slidably inserted into the adjustment slot 11. The adjustment block is fixedly connected to the side wall of the adjustment rod 9. A first spring 10 is fixedly connected between the lower end of the adjustment rod 9 and the bottom surface of the adjustment slot 11. A pressing block 12 is fixedly connected to the upper end of the adjustment rod 9. A limiting insertion hole 16 is provided on the pressing block 12. An L-shaped limiting insert 17 is slidably inserted into the limiting insertion hole 16.

[0018] In practical use, pushing the pressing block 12 causes the adjusting rod 9 to slide downwards, compressing the first spring 10. The adjusting rod 9, through the adjusting block, causes the fixing block 7 to slide downwards. The adjusting rod 9 pushes the supporting swing arm 5 to swing into the movable groove 3, so that the supporting swing arm 5 is fully inserted into the inner side of the movable groove 3. The supporting swing arm 5 drives the gear 6 to rotate, and the gear 6 drives the rack 14 to slide into the control cavity 20, pushing the slider 13 to slide upwards, compressing the second spring 15. Releasing the pressing block 12, under the restoring force of the first spring 10, the fixing block 7 slides upwards, so that the lower end of the supporting swing arm 5 is inserted into the fixing slot 8, fixing the supporting swing arm 5. The L-shaped limiting insert 17 is inserted into the limiting insertion hole 16 of the pressing block 12, so that the L-shaped limiting insert 17 abuts against the upper end of the adjusting slot 11. 12 cannot be pressed down and slid. The phase partition plate 1 is installed and connected to the circuit breaker's connection slot through the connecting plug plate 2, so that the limit plugs 18 on both sides are inserted into the limit slots on both sides of the connection slot. At the same time, the limit baffle 19 is pressed against the uppermost end of the connection slot. The L-shaped limit plug 17 is pulled out from the limit plug hole 16. The pressing block 12 is pushed to drive the adjusting push rod to slide down. The adjusting push rod drives the adjusting block to slide down along the adjusting hole. The adjusting block drives the fixing block 7 to slide down, so that the lower end of the support swing arm 5 is disengaged from the fixing slot 8. Under the restoring force of the second spring 15, the slider 13 is driven to slide down. The slider 13 drives the rack 14 to slide down. The rack 14 drives the gear 6 to rotate in the opposite direction, causing the support swing arm 5 to swing outward, so that the end of the support swing arm 5 is pressed against the inner wall of the circuit breaker connection slot, which greatly improves the stability of the connection.
