Description

Technical Field

[0001] This utility model relates to the field of high-voltage power equipment technology, specifically to an integrated wiring structure inside a horizontal phase-splitting spring mechanism box. Background Technology

[0002] Spring operating mechanisms are a crucial component of high-voltage circuit breakers, and their reliability and stability are essential for their normal operation. With technological advancements, the design and manufacturing levels of spring operating mechanisms are continuously improving to meet higher performance and safety requirements. Horizontal phase-splitting spring mechanisms, as one type, offer advantages such as compact structure and reliable operation, and are widely used in high-voltage circuit breakers.

[0003] For traditional vertical spring mechanisms, in order to facilitate wiring, the wiring inside the mechanism box is usually distributed between the three phases, and the three terminal blocks are usually close to their respective mechanisms, making the terminal blocks relatively dispersed. However, for horizontal spring mechanisms, the mechanism is placed horizontally, and the overall depth and height of the mechanism box are greater than before. If the traditional wiring method is used, the terminal block wiring inside the mechanism box will not be possible. Moreover, due to the increased depth of the mechanism box, it is not convenient for personnel to perform related wiring and testing operations using the traditional wiring method. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an integrated wiring structure within a horizontal phase-splitting spring mechanism box, which facilitates wiring, provides sufficient operating space, and makes subsequent disassembly and replacement convenient.

[0005] This utility model is achieved through the following technical solution: an integrated wiring structure inside a horizontal phase-splitting spring mechanism box. The mechanism box contains three-phase spring mechanisms arranged from left to right. The integrated wiring structure is located at one end of the arrangement direction of the three-phase spring mechanisms. The integrated wiring structure includes three vertical support rods fixed inside the mechanism box. The three vertical support rods are arranged in a front-to-back direction, and a wiring area is formed between adjacent vertical support rods. Multiple horizontal mounting rods are distributed from top to bottom within the wiring area. The two ends of the horizontal mounting rods are fixed to adjacent vertical support rods. Four conduits and three terminal blocks are installed on the horizontal mounting rods in one wiring area. The four conduits and three terminal blocks extend vertically and are spaced apart along the length of the horizontal mounting rod. Two conduits and one vertical mounting rod are installed on the horizontal mounting rods in another wiring area. The two conduits and one vertical mounting rod extend vertically and are spaced apart along the length of the horizontal mounting rod. The vertical mounting rods are used to install components inside the box.

[0006] As an optimization, the upper and lower ends of the vertical support rod are bolted to the inner wall of the mechanism box.

[0007] As an optimization, the end of the horizontal mounting rod is connected and fixed to the vertical support rod via an insulator.

[0008] As an optimization, the vertical support rod has multiple magic holes along its length, and the insulator is bolted to the magic holes.

[0009] As an optimization, the first conduit, terminal block, second conduit, and vertical mounting rod are all bolted onto the horizontal mounting rod.

[0010] As an optimization, the horizontal mounting rod has multiple bolt holes along its length.

[0011] As an optimization, the bolt hole is a rectangular hole.

[0012] As an optimization, four horizontal mounting rods are distributed from top to bottom in the wiring area. The first conduit, terminal block, second conduit, and vertical mounting rod are connected to the three horizontal mounting rods above. The lowest horizontal mounting rod is used to tie and fix the control cable in the mechanism box.

[0013] As an optimization, the mechanism box is provided with two side doors on the side wall near the integrated wiring structure, and the two side doors correspond to the two wiring areas respectively.

[0014] The beneficial effects of this utility model are as follows: By fixing the horizontal mounting rod with a vertical support rod, and integrating the three terminal blocks into one wiring area, the terminal blocks are centrally distributed. When the three-phase spring mechanism is wired to the three terminal blocks respectively, the wiring is more convenient, reducing space occupation and making it more suitable for the wiring arrangement inside the horizontal spring mechanism box. Furthermore, the vertical mounting rod used to install the components inside the box is integrated into another wiring area, allowing for zoned arrangement and making wiring more convenient.

[0015] By installing two side doors on the mechanism box opposite the wiring area, wiring and connection are made more convenient for personnel, and later inspection and management are also facilitated. Furthermore, all structures are connected by bolts, making disassembly and maintenance easy.

[0016] This integrated cabling structure centrally arranges the three-phase terminal blocks and components, achieving a high degree of integration. It is installed on the side door of the control box, making observation and wiring convenient, and resulting in a neater and more aesthetically pleasing finished product. The side door provides ample operating space, facilitating future disassembly and replacement, greatly simplifying maintenance. Attached Figure Description

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] like Figures 1 to 3 As shown, a horizontal phase-separated spring mechanism box with integrated wiring structure is provided. The mechanism box 1 has three phase spring mechanisms 8, namely phase A, phase B and phase C, distributed from left to right. The front side wall of the mechanism box 1 is provided with three front box doors 10, which correspond one-to-one with the three phase spring mechanisms 8, so as to facilitate the operation of the spring mechanisms 8 by personnel. This is the prior art.

[0024] To facilitate wiring of the three-phase spring mechanism and subsequent maintenance, the integrated wiring structure described in this embodiment is located at one end of the three-phase spring mechanism 8 in the arrangement direction.

[0025] The integrated wiring structure includes three vertical support rods 2 fixed inside the mechanism box 1. The three vertical support rods 2 are arranged in a front-to-back direction, and a wiring area 15 is formed between adjacent vertical support rods 2. Specifically, the upper and lower ends of the vertical support rods 2 are bolted to the inner wall of the mechanism box 1 for easy disassembly and maintenance.

[0026] Multiple horizontal mounting rods 3 are distributed from top to bottom within the wiring area 15, and both ends of the horizontal mounting rods 3 are fixedly connected to the adjacent vertical support rods 2. Specifically, the ends of the horizontal mounting rods 3 are connected and fixed to the vertical support rods 2 through insulators 13, which isolate the current and prevent the mechanism box from becoming energized.

[0027] In this embodiment, the vertical support rod 2 has multiple magic holes 21 along its length. The insulator 13 is bolted to the magic holes 21, which facilitates the screwing of the insulator and allows for easy adjustment of the insulator's installation position.

[0028] In one wiring area 15, four conduits 4 and three terminal blocks 5 are installed on a horizontal mounting rod 3. The four conduits 4 and three terminal blocks 5 extend vertically and are spaced apart along the length of the horizontal mounting rod 3. In another wiring area 15, two conduits 6 and one vertical mounting rod 7 are installed on a horizontal mounting rod 3. The two conduits 6 and the vertical mounting rod 7 extend vertically and are spaced apart along the length of the horizontal mounting rod 3. The vertical mounting rod 7 is used to install components 14 inside the enclosure.

[0029] Specifically, the bottom of the mechanism box 1 has three square holes 11 for the entry of external control cables 12. These three square holes 11 are located on the front side of the three-phase spring mechanism 8, which is existing technology. In this embodiment, the three terminal blocks 5 are located in the relatively forward wiring area 15, which is symmetrical to the three square holes 11, making it easier to connect the external control cables 12. The vertical mounting rod 7 is located in the relatively rearward wiring area 15.

[0030] Specifically, four horizontal mounting rods 3 are distributed from top to bottom within the wiring area 15. The first conduit 4, terminal block 5, second conduit 6, and vertical mounting rod 7 are all connected to the three upper horizontal mounting rods 3, while the lowest horizontal mounting rod 3 is used to secure the control cable 12 inside the mechanism box 1. By securing the control cable 12, tangling is avoided, making the internal wiring more aesthetically pleasing.

[0031] Specifically, the conduit 4, terminal block 5, conduit 6, and vertical mounting rod 7 are all bolted onto the horizontal mounting rod 3 for easy disassembly and maintenance.

[0032] In this embodiment, the horizontal mounting rod 3 has multiple bolt holes 31 along its length to facilitate adjustment of different fixing positions. The first conduit, terminal block, second conduit, and vertical mounting rod are connected to the bolt holes by bolts.

[0033] Preferably, the bolt hole 31 is a rectangular hole, and the bolt can be slightly moved in the rectangular hole to finely adjust the fixed position, making the connection more convenient.

[0034] In this embodiment, the conduit 4 and conduit 6 have the same structure, both being cable tray structures. The vertical mounting rod 7 also has multiple rectangular holes along its length, allowing the internal components 14 to be connected to these holes via bolts for easy assembly and disassembly.

[0035] To ensure sufficient operating space for easy inspection and maintenance, the mechanism box 1 has two side doors 9 on the side wall near the integrated cabling structure, each corresponding to one of the two cabling areas 15. In this embodiment, the integrated cabling structure is located at the right end of the three-phase spring mechanism 8, hence the two side doors 9 are installed on the right side wall of the mechanism box 1.

[0036] Working principle: During wiring, the three terminal blocks 5 are connected one-to-one with the three-phase spring mechanism 8. Each terminal block 5 has a conduit 4 on both sides for threading the incoming and outgoing wires respectively. The conduit 4 of the middle terminal block 5 is shared with the terminal blocks on both sides.

[0037] After the external control cable 12 enters the mechanism box 1 through the square hole 11, it must first be secured to the bottom horizontal mounting rod 3 before entering one side of the conduit 4 of the terminal block 5. The control cable 12 exits from the conduit 4 and connects to the corresponding input node of the terminal block 5. The control cable of the output node of the terminal block 5 exits through the other conduit 4 and connects to the spring mechanism 8. Similarly, the internal components 14 are mounted on the vertical mounting rod 7, and a second conduit 6 is distributed on each side of the vertical mounting rod 7 for passing in and out cables.

[0038] Of course, the above description is not limited to the examples above. Technical features not described in this utility model can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model.

Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
