Description

Technical Field

[0001] This utility model relates to the technical field of transposition conductors for reactors, and specifically to transposition conductors for reactors. Background Technology

[0002] A reactor is an electrical device used in circuits for various functions, including limiting current variations and reactive power compensation. Reactors are connected in series in a circuit, using their inductive reactance to limit the peak value of short-circuit current, thereby protecting electrical equipment (such as generators, transformers, and circuit breakers) from the impact of large short-circuit currents. For example, installing reactors between the busbar and feeder in a substation can effectively reduce the short-circuit current level, enabling circuit breakers and other equipment to safely interrupt fault currents within their rated breaking current range. However, the connection position of its conductors (live wire or neutral wire) is unique and fixed, which cannot meet more wiring requirements.

[0003] Existing reactors have fixed conductor connection positions, which cannot provide wiring space for multiple sizes and orientations. For example, the transposed winding conductor for an environmentally friendly reactor disclosed in CN201838360U has at least five intertwined enameled wires within an aromatic polyester amide overall wrapping layer. Each enameled wire has an extruded aluminum core, a heat-resistant polyester primer is applied to the extruded aluminum core, and a polyamide-imide topcoat is applied to the heat-resistant polyester primer. This utility model solves the problems of poor conductor forming density, difficulty in treating the interface between the insulation layer and the conductor, and unsatisfactory insulation effect in existing technologies. It is low-cost, high-performance, and environmentally friendly, and the product can be widely used in industrial and civil fields such as rail transit, nuclear power plants, and power plants. However, the connection position of the conductor in this solution is unique and singular, which cannot meet the wiring requirements of multiple sizes, resulting in poor practicality.

[0004] Therefore, it is necessary to invent a reactor using transposed conductors to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a transposition conductor for reactors, thereby solving the problems in the technology of fixed position of the connecting conductor of reactors, which cannot provide multiple use surfaces and multiple use positions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A transposition conductor for a reactor includes a reactor mounting base, a coil, a first mounting bracket, a fixing bolt, and a second mounting bracket. The coil is mounted on the reactor mounting base. The end of the coil wire is fixed by the first and second mounting brackets. The first mounting bracket is connected to the outside via the fixing bolt. The second mounting bracket has a through hole, and a through groove is formed on the inner wall of the through hole. A first sliding rod is slidably connected in the groove. A transposition mechanism is connected to the first sliding rod, and multiple conductor connectors are connected to the transposition mechanism. The conductor connectors are connected to a limiting protrusion through an inner groove. The limiting protrusion is fixedly connected to the conductor connector end, allowing the end of the coil wire to extend into the conductor connector end.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] This utility model features a transposition mechanism within a through hole in the fixed bracket 2. This transposition mechanism can move laterally within a groove to meet the wiring requirements of live wires of different lengths. The transposition mechanism also features various sizes of wire terminals to accommodate different connection needs. Furthermore, the wire terminals are fixed using a plug-in / pull-out limiting mechanism based on threaded rotation, enhancing the connection's robustness. The transposition mechanism provides more usable surfaces by having wire connection terminals on multiple faces, improving practicality. A knob allows for direction adjustment, enabling the unused face to be rotated to the top for easy use and convenient rotation and positioning, making operation convenient.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model provides, for example Figures 1-3 The reactor transposition conductor shown includes a reactor mounting base 1, a coil 2, a first mounting bracket 3, a fixing bolt 4, and a second mounting bracket 5. The coil 2 is mounted on the reactor mounting base 1. The wire extension of the coil 2 is fixed by the first mounting bracket 3 and the second mounting bracket 5. The first mounting bracket 3 is connected to the outside via the fixing bolt 4. The second mounting bracket 5 has a through hole 501, and a through groove 502 is formed on the inner wall of the through hole 501. A first sliding rod 503 is slidably connected within the groove 502. A transposition mechanism 504 is connected to the first sliding rod 503, and multiple wire connection seats 505 are connected to the transposition mechanism 504. The wire connector 505 is connected to the limiting protrusion 507 through the inner groove 506. The limiting protrusion 507 is fixedly connected to the wire connector 508. The wire winding end of the coil 2 can extend into the wire connector 508. The switching mechanism 504 is rectangular, and wire connectors 505 of different sizes are provided on its four sides. The inner groove 506 in the wire connector 505 is spiral, and the starting end and the initial end of the spiral are vertical. Its vertical size is adapted to the size of the limiting protrusion 507. The limiting protrusion 507 is provided on two opposite sides of the wire connector 508 and has the same size.

[0020] The multiple wire connection terminals 508 of different sizes on the transposition mechanism 504 can be connected to live wire terminals of different sizes, which has a wide range of applications. The threaded limiting mechanism between the wire connection terminal 508 and the limiting protrusion 507 can be easily inserted, removed and rotated, which is more secure than traditional threaded connections.

[0021] The shifting mechanism 504 is also connected to a sliding rod 509. The sliding rod 509 extends out of the end of the fixed bracket 5 and is connected to a telescopic rod 510. A knob 511 is connected to the telescopic rod 510. A plug rod 512 is fixedly connected to the knob 511. The plug rod 512 can be inserted into any of the plug holes 513. The plug holes 513 are evenly arranged on the side of the fixed bracket 5.

[0022] The entire transposition mechanism 504 can slide laterally within the slide groove 502 to adjust its position, and can also adjust its direction longitudinally by rotating the knob 511. The application range of the entire transposition mechanism 504 is increased, and it provides more wiring terminals, thus enhancing its practicality.

[0023] The knob 511 is equipped with multiple pointers, which can be used to visually distinguish the rotation angle. The longest extension length of the telescopic rod 510 is one-quarter of the length of the insertion rod 512. The position of the insertion rod 512 is consistent with the orientation of one of the pointers. Multiple insertion holes 513 are evenly distributed on the upper and lower sides of the slide groove 502 on the side of the fixed bracket 2 5.

[0024] The direction of the shifting mechanism 504 can be rotated using the knob 511, and the direction after rotation can be fixed by the plug 512 on the knob 511.

[0025] Working principle of this utility model:

[0026] Refer to the instruction manual appendix Figures 1-3 When using this utility model, the wound coil 2 is first arranged side by side, and its bottom is installed into the reactor fixing seat 1. The top is clamped between the fixing bracket 1 3 and the fixing bracket 2 5 and then fixed. The reactor is then fixed to the external position (installed in the position where it is needed) using the fixing bolt 4.

[0027] Next, extend the live wire terminal of the entire reactor through the transposition mechanism 504 and connect it to any wire connector 505. To use the wire connector 508 of a certain size, rotate the wire connector 508 on the top side.

[0028] Refer to the instruction manual appendix Figures 3-6 When using this utility model, the connection between the wire connection end 508 and the wire connection seat 505 can also make it easier to replace the live wire terminal in the wire connection end 508 (after inserting the limiting protrusion 507 into the end of the inner groove 506 and rotating it, the two can be fixed, which is more convenient and secure than the traditional threaded fixing).

[0029] When a wire connection terminal 508 of another size needs to be rotated, the originally fixed plug 512 and plug 513 can be pulled out, the telescopic rod 510 is extended, and the idle surface of the switching mechanism 504 is rotated upward by rotating the knob 511. A suitable or idle wire connection terminal 508 can be used. At the same time, the entire switching mechanism 504 can be moved in the slide groove 502, which makes it easy to provide sufficient space according to the length requirements of the external live wire. The entire switching mechanism 504 is highly practical.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
