Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to an adjustable installation structure of a pole-mounted vacuum circuit breaker. Background Art

[0002] A pole-mounted vacuum circuit breaker is installed on an electric pole and is an important device for controlling and protecting electrical equipment in a power system, such as generators, transformers, compensators, motors, etc. It is widely used in power systems, especially in places where frequent operation is required, such as rural power grids, substations, and industrial and mining enterprise distribution systems. It can not only be used to disconnect and switch on load current, overload current, and short-circuit current in the power system, but also can isolate or adjust certain electrical equipment separately in the power system, improving the safety and reliability of the power system.

[0003] After retrieval, the adjustable installation structure of the pole-mounted vacuum circuit breaker disclosed in the Chinese patent with the application number CN202321546622.5, in actual use, the support clamp needs to be fixed after connecting the reinforcement plate to the support clamp, resulting in that after the fixed clamp is installed, only the fixed clamp supports the whole, causing the fixed clamp to bear a large force during installation, being prone to looseness, and having low safety. Therefore, it has the advantages that the first clamp, the second clamp, and the side plate can cooperate to support the support plate during installation at the same time, thereby improving the support strength and avoiding the situation that the first clamp supports alone and is prone to deformation. At the same time, it is convenient to connect and fix the reinforcement plate, making the installation more convenient and having a higher support strength.

[0004] The above-mentioned pole-mounted vacuum circuit breaker is convenient for connecting and fixing the reinforcement plate, making the installation more convenient. When the pole-mounted vacuum circuit breaker is installed on an electric pole, the bracket needs to be installed first and then the circuit breaker is installed. When the pole-mounted vacuum circuit breaker is installed and used, it usually has different sizes, and the bracket during installation is not convenient to adjust according to different sizes of the pole-mounted vacuum circuit breaker, reducing the adaptability between the bracket and the pole-mounted vacuum circuit breaker. Therefore, it is necessary to purchase brackets with different widths to adapt to different sizes of vacuum circuit breakers, increasing the installation cost. Summary of the Utility Model

Two fastening sleeves 2 are arranged outside the pole body 1. Installation plates 3 are fixedly connected to both sides of the two fastening sleeves 2. An installation groove 4 and a sliding groove 5 are formed inside the installation plate 3. A screw rod 6 is rotatably connected inside the installation groove 4. A support rod 7 is threadedly connected to the outside of the screw rod 6. A fixed rod 8 is fixedly connected to the lower surface of the support rod 7. A sliding block 9 is fixedly connected to one side of the fixed rod 8. A support rod 10 is fixedly connected to the front side of the fixed rod 8. The other end of the support rod 10 is fixedly connected to the middle of the support rod 7. A plurality of hole grooves 11 are formed on one side of the installation plate 3. The other end of the screw rod 6 is fixedly connected to a knob 12. A bolt 13 is threadedly connected inside the knob 12. A vacuum circuit breaker body 14 is arranged above the two support rods 7. The sliding block 9 slides inside the sliding groove 5, which is convenient for improving the stability according to the connection of the fixed rod 8 when the support rod 7 moves. The support rod 10 improves the support effect. The bolt 13 is screwed into the knob 12 and inserted into the corresponding hole groove 11, which is convenient for enhancing the limiting and fixing effect after the screw rod 6 rotates.

[0033] As shown in the Figure 6 accompanying drawings, two connecting blocks 16 are fixedly connected to the lower surface of the vacuum circuit breaker body 14. Two fixing blocks 15 are fixedly connected to the lower surface of the vacuum circuit breaker body 14. A through groove 17 is formed inside the connecting block 16. The connecting block 16 is used for installation inside the installation box 19. The fixing block 15 is used for installation inside the placement groove 18. The through groove 17 is convenient for engaging with the limiting column 22.

[0034] As shown in the Figure 5 accompanying drawings, a placement groove 18 is formed on the upper surface of the support rod 7. An installation box 19 is fixedly connected to one side of the support rod 7, which is convenient for installing the fixing block 15 and the connecting block 16.

[0035] As shown in the Figure 7As shown, a fixed box 20 is fixedly connected to the rear side of the installation box 19. A limiting plate 21 is slidably connected inside the fixed box 20. A limiting column 22 is fixedly connected to the middle of the limiting plate 21. A spring 23 is fixedly connected to one side of the limiting plate 21. A threaded column 24 is fixedly connected to one end of the limiting column 22. A nut 25 is threadedly connected to the outside of the threaded column 24.

[0036] As shown in the attachment Figure 1 As shown, a side guard plate 27 is fixedly connected to one side of the support rod 7, which is convenient for protecting both sides.

[0037] Working principle: When installing the vacuum circuit breaker on the installation column, first fit and install the two fastening sleeves 2 at the required installation position on the column body 1. When adjusting the width spacing of the brackets installed on the column body 1, turn the bolt 13 on the knob 12 so that the bolt 13 disengages from the corresponding hole groove 11 inside, so that the knob 12 is released from the limit. Then turn the knob 12, which is convenient for the knob 12 to drive the screw rod 6 to rotate inside the installation groove 4. When the screw rod 6 rotates, it drives the position of the support rod 7 to move. When the support rod 7 moves, through the fixed rod 8, it is convenient to drive the slider 9 to slide inside the chute 5, so as to drive the positions of the support rod 7, the fixed rod 8 and the support rod 10 to move. After moving to the appropriate position, stop turning the knob 12, and then turn the bolt 13 on the knob 12 and screw the bolt 13 into the corresponding hole groove 11 inside to enhance the limiting effect of the screw rod 6. When installing the vacuum circuit breaker body 14 on the two support rods 7, first pull the pulling block 26 so that the pulling block 26 drives the limiting column 22 and the threaded column 24 to move into the fixed box 20. Then insert the bottom connecting block 16 of the vacuum circuit breaker body 14 into the installation box 19, and at the same time insert the fixed block 15 into the placement groove 18, which is convenient for placing the vacuum circuit breaker body 14 stably. Then release the pulled pulling block 26, so that under the action of the spring 23 being compressed and then rebounding, the limiting column 22 is pushed into the through groove 17, and the threaded column 24 extends out from one side of the through groove 17. Then screw the nut 25 onto the outside of the threaded column 24, which is convenient for fixing the position of the limiting column 22, so as to facilitate the limiting and fixing of the connecting block 16 installed in the installation box 19, which is beneficial to improving the tightness of the installation. During disassembly, the operation is the opposite, which is convenient for improving the convenience during disassembly and assembly.
