Description

Technical Field

[0001] The utility model relates to the technical field of supports, and more particularly to a support structure for preventing eddy currents from being generated. Background Art

[0002] The main function of the support structure on the circuit breaker structure is to support and fix the components. The support structure provides the necessary support and fixation for the various components of the circuit breaker, ensuring the stability and reliability of the circuit breaker's overall structure. This helps the circuit breaker maintain a stable operating state under normal operating conditions and prevents failures caused by loose or displaced components.

[0003] Among the existing published literature, Chinese Patent Publication No. CN116130265A discloses a capacitor support and connection structure and circuit breaker. This circuit breaker support structure uses a fixed connection at one end of the capacitor during operation to prevent the capacitor from sliding within the two support bases and causing the ends to be constantly impacted. A sliding conductive connection at one end allows the capacitor at this end to slide relative to the support base, preventing excessive force on both ends of the capacitor during vibration. This solves the problem in the prior art where circuit breaker vibration can be transmitted to the capacitor, causing damage to the capacitor. However, this support structure still has the following drawbacks during use.

[0004] When the supporting structure on the circuit breaker is in use, when a large current passes through the conductor in the supporting part, eddy currents are generated in the supporting structure due to electromagnetic induction. At the same time, resistance will exist, generating a large amount of heat, which will affect the temperature rise control and structural strength of the electrical cabinet. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a support structure for preventing the generation of eddy currents.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a support structure for preventing the generation of eddy currents, comprising a support plate, a conductive plate and a large docking hole, wherein the conductive plate is fixedly located on the upper surface of the support plate, and the large docking hole is opened on the inner wall of the conductive plate, and a spacing anti-eddy current mechanism is provided on one side of the large docking hole; the spacing anti-eddy current mechanism comprises two small docking holes arranged on one side of the large docking hole, and two eddy current spacer blocks are fixedly connected to one side of the support plate, and an inner wall of each eddy current spacer block is provided with a mounting hole; a spacing groove is provided between the two eddy current spacer blocks, a conductive strip is fixedly connected to the bottom end of the conductive plate and at a position between the two eddy current spacer blocks, and a connecting strip is fixedly connected to the bottom end of the conductive strip.

[0007] Preferably, the diameter of the large docking hole is larger than the diameter of the small docking hole, and the cross-sectional shapes of the large docking hole and the small docking hole are both circular. Two positioning holes are opened on one side of the conductive strip, and the two positioning holes are arranged in sequence from top to bottom. The other side of the connecting strip is fixedly connected to a docking support bar, and one side of the docking support bar is chamfered. The outer wall of the support plate is fixedly connected to the side adjacent to the eddy current spacer block with an arc bar, and the bottom end of each arc bar is fixedly connected to a support bar; the two support bars are symmetrically arranged about the support plate.

[0008] According to the above technical solution, when in use, the conductive plate drives the large docking hole to be positioned on the circuit breaker, while the support plate drives the arc-shaped bar to move, and the support bar docks with the circuit breaker bracket. The eddy current spacer drives the mounting hole to dock with the circuit breaker mounting position, and the eddy current spacer is fixed to the end circuit breaker mounting position. Through the power-on position of the circuit breaker, it is inserted into the two positioning holes, the connecting bar is connected to the bottom end of the conductive bar, and then connected to the conductive plate through the conductive bar. The conductive plate supports the conduction, so that the two eddy current spacers can achieve spacing support, which not only avoids the electromagnetic induction effect on the support structure to generate eddy currents, but also makes the spacing between the spacing slots larger, so that the heat is reduced.

[0009] Preferably, a positioning support assembly is installed on the other side of the support plate; the positioning support assembly includes a mounting bar fixedly mounted on the other side of the support plate, and a positioning slot block is fixedly connected to the top of the mounting bar, a positioning slot body is provided on the upper surface of the positioning slot block, and two positioning branch holes are provided on one side of the positioning slot block, the two positioning branch holes are symmetrically arranged about the positioning slot body, and the inner wall of the positioning slot body is a smooth surface.

[0010] According to the above technical solution, when in use, the support plate moves, which drives the mounting bar to move. The positioning groove body on the positioning groove block can be positioned on the clamping part on the circuit breaker, so that the two positioning branch holes can also be synchronously docked with the clamping part on the circuit breaker, and the positioning groove block can be accurately positioned.

[0011] The technical effects and advantages of this utility model are:

[0012] 1. The utility model adopts an interval anti-eddy current mechanism. The conductive plate drives the large docking hole to be positioned on the circuit breaker, and the two small docking holes are inserted into the mounting shaft of the circuit breaker. The eddy current spacer moves, and the eddy current spacer drives the mounting hole to dock at the mounting position of the circuit breaker. It is inserted into the two positioning holes through the power-on position of the circuit breaker. The circuit breaker supplies power to the conductive strip, and the connecting strip is connected to the bottom end of the conductive strip. The spacing groove between the two eddy current spacers can generate a gap, which can make the spacing space between the spacing grooves larger. It not only avoids the electromagnetic induction effect on the support structure to generate induced current eddy current, but also reduces heat, thereby avoiding high temperature of the electrical cabinet and avoiding affecting the temperature rise control and structural strength of the electrical cabinet.

[0013] 2. The utility model utilizes a positioning support assembly. When the support plate moves, the mounting bar moves, and the mounting bar drives the positioning slot block to move. The two positioning support holes on the positioning slot block can also be synchronously docked with the clamping parts on the circuit breaker. The positioning slot block supports the mounting bar, and the positioning stability is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As attached Figure 1-5 A support structure for preventing the generation of eddy currents is shown, and an interval anti-eddy current mechanism is provided on the support structure for preventing the generation of eddy currents. The setting of the interval anti-eddy current mechanism not only prevents the electromagnetic induction from generating induced current eddy currents in the support structure, but also generates less heat, thereby avoiding high temperature of the electrical cabinet and avoiding affecting the temperature rise control and structural strength of the electrical cabinet. The specific structural setting of the interval anti-eddy current mechanism is as follows.

[0022] In this technical solution, as shown in the attached Figure 1-4 As shown, the conductive plate 2 is fixed on the upper surface of the support plate 1, and the large docking hole 3 is opened on the inner wall of the conductive plate 2, and a spacing anti-eddy current mechanism is provided on one side of the large docking hole 3; the spacing anti-eddy current mechanism includes two small docking holes 4 arranged on one side of the large docking hole 3, and two eddy current spacer blocks 5 are fixedly connected to one side of the support plate 1, and the inner wall of each eddy current spacer block 5 is provided with a mounting hole 6; a spacing groove 7 is provided between the two eddy current spacer blocks 5, and a conductive bar 8 is fixedly connected to the bottom end of the conductive plate 2 and located between the two eddy current spacer blocks 5, and a connecting bar 9 is fixedly connected to the bottom end of the conductive bar 8, the diameter of the large docking hole 3 is larger than the diameter of the small docking hole 4, and the cross-sectional shapes of the large docking hole 3 and the small docking hole 4 are both circular.

[0023] In this technical solution, as shown in the attached Figure 1-4 As shown, one side of the conductive bar 8 is provided with two positioning holes 10, which are arranged in sequence from top to bottom so that the circuit breaker can be inserted into the two positioning holes 10 at the power-on position to achieve positioning installation. The other side of the connecting bar 9 is fixedly connected to a docking support bar 11, and one side of the docking support bar 11 is rounded to facilitate the docking support bar 11 to be conductively connected to the conductive bar 8, and connected to the conductive plate 2 through the conductive bar 8, so that the conductive plate 2 can be conductively operated through the conductive bar 8. The outer wall of the support plate 1 and the side adjacent to the eddy current spacer block 5 are fixedly connected to an arc bar 12, and the bottom end of each arc bar 12 is fixedly connected to a support bar 13; the two support bars 13 are symmetrically arranged about the support plate 1 so that the support plate 1 drives the arc bar 12 to move, and the arc bar 12 drives the support bar 13 to move, and the support bar 13 is docked with the circuit breaker bracket to achieve precise positioning and docking of the side of the support plate 1, greatly improving the docking efficiency.

[0024] When using the support structure for preventing eddy currents in this technical solution, support plate 1 is first moved downward, which drives conductive plate 2 downward. Conductive plate 2 drives large docking hole 3 to be positioned on the circuit breaker, and two small docking holes 4 are inserted into the circuit breaker's mounting axis. Simultaneously, support plate 1 drives curved bar 12 to move, which in turn drives support bar 13 to dock with the circuit breaker bracket. Simultaneously, eddy current spacer 5 moves, driving mounting hole 6 to dock with the circuit breaker mounting position. Bolts are then inserted into mounting hole 6 to secure eddy current spacer 5 to the circuit breaker mounting position.

[0025] The circuit breaker is inserted into the two positioning holes 10 through the power-on position, and the circuit breaker supplies power to the conductive bar 8, and the connecting bar 9 is connected to the bottom end of the conductive bar 8, and the docking branch bar 11 is conductively connected to the conductive bar 8, and is connected to the conductive plate 2 through the conductive bar 8. The conductive support is achieved by the conductive plate 2, so that the two eddy current spacer blocks 5 can achieve spacing support. At the same time, the spacing groove 7 between the two eddy current spacer blocks 5 can generate a spacing, which not only avoids the electromagnetic induction effect to generate induced current eddy current in the support structure, but also makes the spacing space of the spacing groove 7 larger, so that the heat is smaller, thereby avoiding the high temperature of the electrical cabinet, and can improve the strength of the eddy current spacer block 5, avoiding excessive heat causing the eddy current spacer block 5 to be easily damaged by high heat.

[0026] In this technical solution, as shown in the attached Figure 5 As shown, a positioning support assembly is mounted on the other side of the support plate 1. The positioning support assembly includes a mounting bar 14 fixedly mounted on the other side of the support plate 1. A positioning slot block 15 is fixedly connected to the top of the mounting bar 14. The upper surface of the positioning slot block 15 defines a positioning slot body 16. One side of the positioning slot block 15 defines two positioning support holes 17. The two positioning support holes 17 are symmetrically arranged about the positioning slot body 16. The inner wall of the positioning slot body 16 is a smooth surface.

[0027] When the present technical solution is in use, the movement of the support plate 1 drives the mounting bar 14 to move, and the mounting bar 14 drives the positioning slot block 15 to move. The positioning slot body 16 on the positioning slot block 15 can be positioned on the clamping part on the circuit breaker. At the same time, the two positioning branch holes 17 on the positioning slot block 15 can also be synchronously docked with the clamping part on the circuit breaker. In this way, the positioning slot block 15 can be accurately positioned. The positioning slot block 15 supports the mounting bar 14, and the mounting bar 14 provides supporting force for the support plate 1.
