Abstract
Description
Technical Field
[0001] This utility model relates to the field of reactor technology, and more specifically, to a multi-winding reactor structure. Background Technology
[0002] A reactor is an electrical device mainly composed of windings and an iron core. It plays an important role in power systems and electronic circuits. When a short-circuit fault occurs in a power system, the reactor can exhibit a large reactance, thereby limiting the magnitude of the short-circuit current, preventing excessive short-circuit current from damaging electrical equipment, and ensuring the stability and reliability of the power system. For example, in substations, series reactors can limit short-circuit current and protect equipment such as transformers and switches.
[0003] A search revealed that Chinese patent CN213459365U discloses a winding structure and a reactor. This utility model reduces the winding size and overall size of the reactor by connecting the ends of the first winding and the second winding through a shorting bar, thereby reducing the amount of raw materials used, lowering raw material costs, saving assembly time, reducing labor costs, and improving the accuracy of wiring at the shorting point.
[0004] When the above-mentioned reactor is in use, the first winding is wound on the first iron core column. However, the overall electromagnetic interference is poor. When the reactor is working, it will generate an electromagnetic field. If the electromagnetic interference suppression is poor, the electromagnetic waves generated may interfere with the surrounding electronic equipment, communication equipment, etc., affecting the normal operation of these devices. At the same time, the electromagnetic coupling between the windings and between the windings and the iron core is not optimized, resulting in increased losses and reduced efficiency of the reactor itself. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-winding reactor structure, which aims to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-winding reactor structure, comprising a mounting shell, multiple iron cores, and multiple windings. The bottom ends of the multiple iron cores and multiple windings extend into the interior of the mounting shell, and the multiple windings are movably sleeved on the multiple iron cores. A protective frame is movably provided on the top of the mounting shell. An anti-interference component is provided between the protective frame and the mounting shell. The anti-interference component includes a shielding plate, two second upright plates, a locking bolt, and two insert rods. The top and bottom ends of the two second upright plates are fixedly connected to the two insert rods and the shielding plate, respectively. A moving component is provided on the top of the anti-interference component. The moving component includes a lead screw, multiple sliders, multiple first upright plates, and two sliding rods. Both ends of the lead screw are movably connected to the protective frame through bearings, and the outer side of the lead screw is threadedly connected to the multiple sliders. The top ends of the multiple first upright plates are fixedly connected to the multiple sliders, respectively.
[0007] Furthermore, the two first upright plates are fixed to the two second upright plates by locking bolts, and the top ends of the two inserts extend into the interior of one of the sliders.
[0008] Furthermore, one end of each of the two slide rods passes through multiple sliders, and the two slide rods are fixedly installed inside the protective frame.
[0009] As can be seen, in the above technical solution, two sliding rods restrict the rotation of multiple sliders.
[0010] Furthermore, a handle is movably provided on one side of the protective frame, and one end of the handle is fixedly connected to the lead screw.
[0011] It can be seen that the above technical solution is designed to facilitate the rotation of the lead screw.
[0012] Furthermore, the protective frame is fixedly connected to side plates on both the front and rear sides, and each of the two side plates is provided with a second fixing bolt. The two side plates are fixed to the mounting shell by two second fixing bolts respectively.
[0013] It can be seen that the above technical solution facilitates the release of the fixing between the protective frame and the mounting shell.
[0014] Furthermore, the bottom of the protective frame is movably provided with two pressure plates, and the bottom of the two pressure plates is in contact with multiple windings. Each of the two pressure plates is provided with two first fixing bolts, and the two pressure plates are fixed to the mounting shell by the two first fixing bolts respectively.
[0015] Furthermore, one of the pressure plates has two copper busbars on its top, and the bottom ends of the two copper busbars are in contact with the winding.
[0016] As can be seen, the above technical solution can reliably connect the various parts of the reactor, allowing the current to flow smoothly through the reactor.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] 1. This utility model places the shielding plate at the bottom of the slider and fixes the shielding plate and the slider together with the locking bolt. Similarly, other shielding plates are installed. Multiple shielding plates can shield the high-frequency electromagnetic field at the top of the mounting shell. Turning the handle will drive multiple shielding plates to move horizontally. The position of the shielding plates can be adjusted as needed, thereby reducing magnetic coupling between windings, reducing mutual inductance interference, and making the operation simple and effectively improving the electromagnetic interference resistance of the reactor.
[0019] 2. This utility model protects the iron core and windings with a protective frame. By rotating the two second fixing bolts in sequence and moving them away from the mounting shell, the fixing between the protective frame and the mounting shell is released. The protective frame is then moved upward and away from the mounting shell. Then, the two copper busbars, multiple iron cores and multiple windings inside the mounting shell can be disassembled and replaced. The structure is simple and easy to use.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Refer to the instruction manual appendix Figure 1-3 This embodiment of a multi-winding reactor structure includes a mounting shell 1, multiple iron cores 2, and multiple windings 3. The bottom ends of the multiple iron cores 2 and multiple windings 3 extend into the interior of the mounting shell 1, and the multiple windings 3 are respectively movably sleeved on the multiple iron cores 2. A protective frame 7 is movably provided on the top of the mounting shell 1. An anti-interference component 11 is provided between the protective frame 7 and the mounting shell 1. The anti-interference component 11 includes a shielding plate 111, two second upright plates 112, locking bolts 113, and two insertion rods 114. The top and bottom ends of the upright plate 112 are fixedly connected to two insert rods 114 and shielding plate 111, respectively. The top of the anti-interference component 11 is provided with a moving component 10. The moving component 10 includes a lead screw 101, multiple sliders 102, multiple first upright plates 103 and two sliding rods 104. Both ends of the lead screw 101 are movably connected to the protective frame 7 through bearings, and the outer side of the lead screw 101 is threadedly connected to multiple sliders 102. The top ends of the multiple first upright plates 103 are fixedly connected to multiple sliders 102, respectively.
[0029] Furthermore, the two first upright plates 103 and the two second upright plates 112 are fixed together by locking bolts 113. The top ends of the two insert rods 114 extend into the interior of one of the sliders 102. One end of each of the two slide rods 104 passes through multiple sliders 102. The two slide rods 104 are fixedly installed inside the protective frame 7. A handle 105 is movably provided on one side of the protective frame 7, and one end of the handle 105 is fixedly connected to the lead screw 101.
[0030] Furthermore, side plates 8 are fixedly connected to both the front and rear sides of the protective frame 7. Each side plate 8 is provided with a second fixing bolt 9, and the two side plates 8 are fixed to the mounting shell 1 by two second fixing bolts 9 respectively. Two pressure plates 4 are movably provided at the bottom of the protective frame 7, and the bottom of each pressure plate 4 is in contact with multiple windings 3. Each pressure plate 4 is provided with two first fixing bolts 5, and the two pressure plates 4 are fixed to the mounting shell 1 by two first fixing bolts 5 respectively. Two copper busbars 6 are provided on the top of one of the pressure plates 4, and the bottom ends of the two copper busbars 6 are in contact with the windings 3.
[0031] The reactor uses a protective frame 7 to protect the iron core 2 and winding 3. By rotating the two second fixing bolts 9 and moving them away from the mounting shell 1, the fixing between the protective frame 7 and the mounting shell 1 is released. The protective frame 7 is then moved upwards and away from the mounting shell 1. The two copper busbars 6, multiple iron cores 2, and multiple windings 3 inside the mounting shell 1 are then disassembled and replaced. The windings 3 are limited and fixed by the first fixing bolt 5 and the pressure plate 4. The two copper busbars 6 can reliably connect the various parts of the reactor, allowing the current to flow smoothly through the reactor. The structure is simple and easy to use. The multiple windings 3 are connected in parallel or series, with each winding 3 carrying a portion of the current, thereby reducing the current density of a single winding 3 and reducing heat generation and losses.
[0032] The usage method of this embodiment is as follows:
[0033] In use, the shielding plate 111 is placed at the bottom of the slider 102, and both insert rods 114 are inserted into the slider 102, thereby improving the stability between the shielding plate 111 and the slider 102. The two second upright plates 112 and the two first upright plates 103 are fixed together by the locking bolts 113, thereby fixing the shielding plate 111 and the slider 102. Similarly, other shielding plates 111 are installed. The multiple shielding plates 111 can shield the high-frequency electromagnetic field at the top of the mounting shell 1. Turning the handle 105 drives the lead screw 101 to rotate. Since the multiple sliders 102 are threaded to the lead screw 101, and the two slide rods 104 restrict the rotation of the multiple sliders 102, the lead screw 101 can drive the multiple sliders 102 to move horizontally, thereby driving the multiple shielding plates 111 to move horizontally. The position of the shielding plate 111 can be adjusted as needed to reduce the magnetic coupling between the windings, reduce mutual inductance interference, simplify operation, and effectively improve the reactor's anti-electromagnetic interference capability.
