Description

Technical Field

[0002] With the continuous advancement of smart grid construction, pole-mounted circuit breakers, as important equipment in the distribution network, directly affect the safe and stable operation of the power grid in terms of their reliability and intelligence level. In recent years, capacitor-powered deep-integrated pole-mounted circuit breakers have been widely used due to their advantages such as no need for external power supply, convenient installation, and high level of intelligence.

[0003] Existing equipment mostly adopts a fixed installation structure, and the spacing between the two mounting blocks and the height between the mounting blocks and the equipment cannot be adjusted. This makes it difficult to adapt to different specifications of poles and installation environments, causing inconvenience to on-site installation and even affecting the stable operation of the equipment. Pole-mounted circuit breakers are exposed to the outdoors for a long time and are inevitably affected by external factors such as wind vibration and mechanical vibration. Long-term vibration can easily lead to loosening of internal components and fatigue fracture of connectors, thereby affecting the service life and reliability of the equipment. Therefore, a capacitor-powered deep-integrated pole-mounted circuit breaker is designed to change the above-mentioned technical defects. Utility Model Content

[0026] This specific embodiment is a capacitor-powered, deeply integrated pole-mounted circuit breaker, and its structural schematic diagram is shown below. Figures 1-6 As shown, the pole-mounted circuit breaker includes a circuit breaker housing 1, with side mounting boxes 2 at both ends of the circuit breaker housing 1. A rectangular sliding box 3 is slidably connected inside the side mounting box 2. Two L-shaped mounting plates 4 are arranged between the two rectangular sliding boxes 3. A moving mechanism for moving the two L-shaped mounting plates 4 is arranged between the two rectangular sliding boxes 3.

[0027] The side mounting box 2 is equipped with a lifting mechanism for raising and lowering the rectangular sliding box 3;

[0028] The moving mechanism includes a first transverse threaded rod 6, a second transverse threaded rod 7 is provided at one end of the first transverse threaded rod 6, the threads of the first transverse threaded rod 6 and the second transverse threaded rod 7 are opposite in direction, a crossbar is provided at the end of the first transverse threaded rod 6 away from the second transverse threaded rod 7, a handwheel 5 is fixed at the end of the crossbar away from the first transverse threaded rod 6, and the first transverse threaded rod 6 and the second transverse threaded rod 7 are respectively threadedly connected to two L-shaped mounting plates 4;

[0029] A transverse light rod 8 is fixed on both sides between the two rectangular sliding boxes 3. The transverse light rod 8 passes through the interior of the L-shaped mounting plate 4 and is slidably connected to the L-shaped mounting plate 4, so that the L-shaped mounting plate 4 can move laterally on the outside of the transverse light rod 8, thereby allowing the spacing between the two L-shaped mounting plates 4 to be adjusted to adapt to different installation requirements.

[0030] The crossbar passes through the interior of the rectangular sliding box 3 and is rotatably connected to the rectangular sliding box 3 via a bearing. The bearing allows the crossbar to rotate inside the rectangular sliding box 3. The rotation of the handwheel 5 allows the crossbar to rotate inside the rectangular sliding box 3. The rotation of the crossbar allows the first transverse threaded rod 6 and the second transverse threaded rod 7 to rotate.

[0031] Here, when it is necessary to adjust the distance between the two L-shaped mounting plates 4, the rotation of the handwheel 5 allows the crossbar to rotate inside the rectangular sliding box 3, thereby allowing the first transverse threaded rod 6 and the second transverse threaded rod 7 to rotate. The rotation of the first transverse threaded rod 6 and the second transverse threaded rod 7 allows the two L-shaped mounting plates 4 to slide laterally outside the transverse smooth rod 8, thereby allowing the distance between the two L-shaped mounting plates 4 to be adjusted.

[0032] The lifting mechanism includes a longitudinal dovetail slider 14. The top of the longitudinal dovetail slider 14 is fixed inside the side mounting box 2. Both ends of the longitudinal dovetail slider 14 are slidably connected to longitudinal sliding seats 13. The bottom of the longitudinal sliding seat 13 is rotatably connected to a first circular mounting seat 9 through a pin. A second circular mounting seat 10 is provided at the bottom of the first circular mounting seat 9. An oblique rotating column 15 is fixed at the bottom of the second circular mounting seat 10. A transverse rotating shaft 16 is rotatably connected to the intersection of the two oblique rotating columns 15 through a bearing. The transverse rotating shaft 16 is located inside the rectangular sliding box 3 and is fixedly connected to the rectangular sliding box 3. A hydraulic cylinder 11 is provided between the first circular mounting seat 9 and the second circular mounting seat 10. An oblique rigid spring 12 is provided between the first circular mounting seat 9 and the second circular mounting seat 10 and outside the hydraulic cylinder 11.

[0033] The longitudinal sliding seat 13 has a dovetail groove inside. The longitudinal sliding seat 13 and the longitudinal dovetail slider 14 are slidably connected through the dovetail groove. The dovetail groove allows the longitudinal sliding seat 13 to slide longitudinally on the outside of the longitudinal dovetail slider 14. By adjusting the sliding of the longitudinal sliding seat 13 on the outside of the longitudinal dovetail slider 14, the lifting height of the rectangular sliding box 3 inside the side mounting box 2 can be adjusted.

[0034] Both ends of the side mounting box 2 are slidably connected to longitudinal sliding plates 17. A transverse limiting rod 18 is slidably connected inside the longitudinal sliding plate 17. A circular pull block 19 is fixed to one end of the transverse limiting rod 18. A circular pull block 19 is provided between the circular pull block 19 and the longitudinal sliding plate 17 and outside the transverse limiting rod 18. A circular through hole adapted to the transverse limiting rod 18 is opened inside the longitudinal sliding seat 13. The transverse limiting rod 18 can slide laterally inside the longitudinal sliding seat 13 through the circular through hole.

[0035] The interior of the longitudinal dovetail slider 14 is provided with a plurality of circular limiting holes that are evenly distributed and fit with the transverse limiting rod 18. The circular limiting holes allow the transverse limiting rod 18 to enter the interior of the longitudinal dovetail slider 14, thereby restricting the sliding of the longitudinal sliding seat 13 on the outside of the longitudinal dovetail slider 14.

[0036] Here, the circular pull block 19 is pulled away from the side mounting box 2. The pulling of the circular pull block 19 allows the lateral limit rod 18 to slide inside the longitudinal sliding plate 17. The pulling of the circular pull block 19 causes the lateral rigid spring 20 to deform under force. When the lateral limit rod 18 moves out of the interior of the longitudinal dovetail slider 14, the longitudinal sliding seat 13 can slide longitudinally on the outside of the longitudinal dovetail slider 14. Through the movement of the two longitudinal sliding seats 13, the oblique rotating column 15 and the lateral rotating shaft 16 allow the rectangular sliding box 3 to rise and fall inside the side mounting box 2, thereby adjusting the height position of the L-shaped mounting plate 4.

[0037] When the circuit breaker housing 1 vibrates, the rectangular sliding box 3 can slide inside the side mounting box 2. The hydraulic cylinder 11 and the oblique rigid spring 12 can reduce the vibration of the circuit breaker housing 1, prevent the circuit breaker housing 1 from being damaged due to long-term vibration, and thus improve the service life of the circuit breaker housing 1.

[0038] By setting an L-shaped mounting plate 4 with adjustable spacing, it can adapt to poles of different specifications and installation environments. By setting an L-shaped mounting plate 4 with adjustable height, the distance between the circuit breaker enclosure 1 and the pole can be flexibly adjusted, ensuring the stability and reliability of the circuit breaker enclosure 1 installation. It can effectively absorb and reduce the vibration generated during the operation of the circuit breaker enclosure 1, reduce the damage of vibration to the internal components of the circuit breaker enclosure 1, and extend the service life of the circuit breaker enclosure 1.

[0039] Working principle: When using the pole-mounted circuit breaker of this technical solution, if it is necessary to adjust the distance between the two L-shaped mounting plates 4, the rotation of the handwheel 5 allows the crossbar to rotate inside the rectangular sliding box 3, thereby allowing the first transverse threaded rod 6 and the second transverse threaded rod 7 to rotate. The rotation of the first transverse threaded rod 6 and the second transverse threaded rod 7 allows the two L-shaped mounting plates 4 to slide laterally outside the transverse smooth rod 8, thereby allowing the distance between the two L-shaped mounting plates 4 to be adjusted, which facilitates better installation of the circuit breaker housing 1 with external equipment.

[0040] Pull the circular pull block 19 away from the side mounting box 2. Pulling the circular pull block 19 allows the lateral limit rod 18 to slide inside the longitudinal sliding plate 17. Pulling the circular pull block 19 causes the lateral rigid spring 20 to deform under force. When the lateral limit rod 18 moves out of the interior of the longitudinal dovetail slider 14, the longitudinal sliding seat 13 can slide longitudinally on the outside of the longitudinal dovetail slider 14. Through the movement of the two longitudinal sliding seats 13, the oblique rotating column 15 and the lateral rotating shaft 16 allow the rectangular sliding box 3 to rise and fall inside the side mounting box 2, thereby adjusting the height position of the L-shaped mounting plate 4.

[0041] When the circuit breaker housing 1 vibrates, the rectangular sliding box 3 can slide inside the side mounting box 2. The hydraulic cylinder 11 and the oblique rigid spring 12 can reduce the vibration of the circuit breaker housing 1, prevent the circuit breaker housing 1 from being damaged due to long-term vibration, and thus improve the service life of the circuit breaker housing 1.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
