Description

Technical Field

[0001] This utility model belongs to the field of circuit breaker technology, specifically relating to an outdoor high-voltage isolation grounding type vacuum circuit breaker. Background Technology

[0002] Outdoor high-voltage isolated grounding vacuum circuit breakers are important circuit control and operation equipment in current power transmission and distribution lines. The term "vacuum circuit breaker" derives from the fact that both the arc-extinguishing medium and the insulating medium between the contacts after arc extinguishing are in high vacuum, and they are widely used in power distribution networks. However, existing outdoor high-voltage isolated grounding vacuum circuit breakers are installed on mounting structures using fixed brackets. Therefore, the size and dimensions of the brackets need to be customized before installation. However, when installing in different locations or making installation adjustments, the brackets need to be adjusted, and existing fixed brackets are inconvenient to adjust. Furthermore, with existing circuit breakers fixed to their brackets, removing the circuit breaker requires simultaneously disassembling the bracket, which is cumbersome and inconvenient for individual circuit breaker maintenance, disassembly, or replacement. Therefore, this utility model provides an outdoor high-voltage isolated grounding vacuum circuit breaker to solve the above problems. Summary of the Invention

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] like Figure 1-5 This utility model discloses an outdoor high-voltage isolation and grounding type vacuum circuit breaker. The outdoor high-voltage isolation and grounding type vacuum circuit breaker includes a bracket 1, a circuit breaker body 2, a movable connection structure 3, a first fixing structure 4, and a second fixing structure 5. The movable connection structure 3 is installed at the bottom of the bracket 1. The circuit breaker body 2 is installed on the bracket 1 via the first fixing structure 4 and the second fixing structure 5. The first fixing structure 4 includes a fixing plate 6, a threaded post 7, a locking nut 8, a limiting rod 9, and a first magnet 10. Support plates 11 are installed on the top of both the left and right sides of the bracket 1, and the threaded post 7 is installed on the support plate 11. Fixing plates 6 are installed on both the left and right sides of the circuit breaker body 2, and the fixing plates 6 are provided with a design for easy mounting. The locking nut 8 is threaded onto the threaded post 7 and located above the fixing plate 6. Symmetrical side ears 12 are provided on both sides of the locking nut 8. Fixing holes 13 are provided on the side ears 12 and the support plate 11. A first magnet 10 is installed in the fixing hole 13. The limiting rod 9 is T-shaped and inserted into the fixing hole 13. The limiting rod 9 is a magnetic metal rod that can attract the first magnet 10. When installing the circuit breaker, the circuit breaker is installed on the bracket, the fixing plate is fitted onto the threaded post, and then the locking nut is installed on the threaded post. The locking nut is tightened, and the limiting rod is inserted into the fixing hole to attract the first magnet. This reduces the loosening of the locking nut and provides a more stable installation of the circuit breaker. The bracket is installed on the mounting structure via a movable connection structure with adjustable spacing, facilitating adaptation to the mounting structure and convenient bracket installation. Simultaneously, the circuit breaker body is easily disassembled and installed on the bracket via the first and second fixing structures, facilitating circuit breaker fixation and easy disassembly and replacement when needed.

[0018] The movable connection structure 3 includes a connecting plate 14, a bidirectional threaded rod 15, a slider 16, a driving bevel gear 17, a driven bevel gear 18, and a handle 19. The bottom of the support 1 is provided with a sliding groove 20, one end of which has a recess 21. The bidirectional threaded rod 15 is installed in the sliding groove 20, with one end extending into the recess 21 and connected to the driven bevel gear 18. A rotating shaft extending into the recess 21 is installed at the bottom of the support 1. One end of the rotating shaft is fixedly connected to the driving bevel gear 17, which meshes with the driven bevel gear 18. The other end of the rotating shaft is connected to a handle 19. Both ends of the threaded rod 15 are threadedly connected to sliders 16. Connecting plates 14 are installed on the bottom of both sides of the sliders 16. The connecting plates 14 are provided with multiple threaded holes 22. The bidirectional threaded rod is a lead screw including a left-hand threaded section and a right-hand threaded section, and sliders are threadedly connected to both the left-hand threaded section and the right-hand threaded section. When it is necessary to adjust the spacing of the connecting plates, turn the handle to rotate the driving bevel gear through the rotating shaft, which drives the driven bevel gear meshing with the driving bevel gear to rotate, thereby rotating the bidirectional threaded rod and making the connecting plates move closer or further apart to adjust the spacing. The bracket can be installed on the mounting structure using bolts.

[0019] The second fixing structure 5 includes a fixing sleeve 23, a fixing rod 24, a pin 25, and a second magnet 26. Fixing sleeves 23 are installed on the left and right rear ends of the circuit breaker body 2, and base plates 27 are installed on the left and right rear ends of the bracket 1. The fixing rod 24 is installed on the base plate 27, and the fixing sleeve 23 is fitted onto the fixing rod 24. Pin holes 28 are correspondingly provided on the fixing sleeve 23, the fixing rod 24, and the circuit breaker body 2. A second magnet 26 is installed at the bottom of the pin hole 28. The pin 25 is a magnetic metal rod, inserted into the pin hole 28 and attracted to the second magnet 26. When installing the circuit breaker, the fixing sleeve is fitted onto the fixing rod, and the pin holes on the fixing sleeve, the fixing rod, and the circuit breaker body are aligned. The pin is inserted into the pin hole and attracted to the second magnet, enhancing the stability between the bracket and the circuit breaker.

[0020] The bracket 1 has multiple support slots 29 on its top, and the circuit breaker body 2 has multiple support rods 30 installed in the support slots 29 on its bottom; this facilitates the support and installation of the circuit breaker.

[0021] Work process:

[0022] The working principle of this utility model is as follows: When installing bracket 1, adjust the spacing of connecting plates 14, rotate handle 19, and rotate the driving bevel gear 17 through the rotating shaft, which drives the driven bevel gear 18 that meshes with the driving bevel gear 17 to rotate, thereby causing the bidirectional threaded rod 15 to rotate, so that the connecting plates 14 move closer or further apart. Adjust the spacing, and use bolts to install bracket 1 on the mounting structure; When installing circuit breaker, support rod 30 is installed in support groove 29, fixing sleeve 23 is fitted on fixing rod 24, fixing sleeve 23, fixing rod 24 and pin hole 28 on circuit breaker body 1 are aligned, pin rod 25 is inserted into pin hole 28 and attracted to second magnet 26, fixing plate 6 is fitted on threaded post 7, and locking nut 8 is installed on threaded post 7. Tighten locking nut 8, insert limiting rod 9 into fixing hole 13 and attracted to first magnet 10, which can reduce the loosening of locking nut 8 by rotation, and facilitate stable installation of circuit breaker.

[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
