Description

Technical Field

[0001] This utility model relates to the field of busbar fixing technology, specifically to the structure of a high-current busbar insulator-to-busbar clamp, which is suitable for the transition of high-current busbars using insulator supports and clamps. Background Technology

[0002] When existing semi-insulated or fully insulated busbars require support from post insulators outdoors, the selection of clamps should be based on the conductor selection of the busbar. For high-current busbars (>6300A), the conductor diameter completely exceeds the upper limit of standard clamp specifications (≤170mm), making it impossible to effectively connect the clamp and the insulator. This necessitates an adapter structure to transfer and fix the clamp to the insulator. Without an adapter structure, the clamp requires a completely new mold design, resulting in extremely high design costs. Utility Model Content

[0003] In view of the above-mentioned technical problem that the clamp cannot be connected to the post insulator when the high current busbar exceeds the standard clamp specifications, the purpose of this utility model is to provide a structure for a high current busbar insulator transfer clamp. This structure can effectively connect the clamp and the insulator when using a high current busbar; and solve the problem of fixing the high current busbar to the insulator, so that it can be fixed in an insulated manner.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a structure for a high-current busbar insulator to busbar transfer clamp, comprising: a busbar clamp, a busbar clamped in the busbar clamp, a post insulator, and a transfer transition plate; the busbar is clamped in the busbar clamp and connected to the transfer transition plate through the fixing parts of the busbar clamp; the post insulator is located below the transfer transition plate, the top of the post insulator is fixedly connected to the transfer transition plate, and the bottom of the post insulator is fixed to the horizontal plane by bolts;

[0005] Based on the above solution of this application, the busbar is a high-current busbar with a diameter specification greater than 170mm;

[0006] Furthermore, the busbar clamp is a split-type clamp structure, including an upper half and a lower half. The inner walls of the upper half and the lower half are designed as arc-shaped structures that fit the outer diameter of the busbar. Fixing connection parts are respectively provided at the docking positions on the outer sides of the upper half and the lower half. The upper half and the lower half are connected together by the fixing parts passing through the fixing parts. The lower end of the fixing part extends to the transition plate and is connected to the transition plate by a nut.

[0007] Furthermore, the fixed connection part has a platform extending outward synchronously from the joint of the upper and lower halves on the same side, and bolt holes are provided on the upper and lower platforms respectively; the fastener uses long bolts, and when in use, the long bolts pass through the bolt holes of the upper and lower halves in sequence to achieve clamping and fixing of the busbar;

[0008] Furthermore, the transition plate is a rectangular plate structure, with through holes for long bolts to pass through on the upper end face at both ends along the length of the transition plate. In use, after the lower end of the long bolt of the busbar clamp passes through the through hole of the transition plate, it is fastened to the transition plate by nuts, thereby realizing the connection between the busbar clamp and the transition plate.

[0009] Furthermore, the two through holes on the transition plate are designed as elongated oval shapes, which facilitates adaptive adjustments for different busbar clamp specifications on the transition plate;

[0010] Furthermore, the post insulator and the transition plate are connected by bolts; the post insulator has multiple threaded holes evenly distributed at the center of its top, and the transition plate has countersunk holes that correspond one-to-one with the threaded holes on the top of the post insulator. The connection between the transition plate and the post insulator is achieved by passing bolts through the countersunk holes of the transition plate and the threaded holes of the post insulator.

[0011] Furthermore, the number of countersunk holes on the transition plate is equal to the number of threaded holes on the top of the post insulator.

[0012] The beneficial effects of adopting this solution are:

[0013] This solution uses a transition plate as a transition structure, which serves as a transitional connection between the clamps of the high-current busbar and the post insulator, thus solving the problem of fixing the high-current busbar to the post insulator; the structure is simple in design and easy to use.

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] In this embodiment, the busbar 2 is a high-current busbar with a conductor diameter of 170*10 and an outer sheath diameter of 185mm.

[0022] Furthermore, the busbar clamp 1 is a split-type clamp structure, including an upper half 1.1 and a lower half 1.2. The inner walls of the upper half 1.1 and the lower half 1.2 are designed as arc-shaped structures that fit the outer diameter of the busbar 2. Fixing connection parts 1.3 are respectively provided at the docking positions on the outer sides of the upper half 1.1 and the lower half 1.2. The upper half 1.1 and the lower half 1.2 are connected together by the fixing parts passing through the fixing connection parts 1.3. The lower end of the fixing part extends to the transition plate 4 and is connected to the transition plate 4 by a nut 5.

[0023] Furthermore, the fixed connection part 1.3 has a platform extending outward synchronously from the joint of the upper half 1.1 and the lower half 1.2 on the same side, and bolt holes are provided on the upper and lower platforms respectively; the fastener adopts a long bolt 6, which passes through the bolt holes of the upper half 1.1 and the lower half 1.2 in sequence to clamp and fix the busbar 2.

[0024] Furthermore, the transition plate 4 is a rectangular plate structure. The upper end face of both ends of the transition plate 4 in the length direction is provided with through holes 7 for long bolts 6 to pass through. In use, after the lower end of the long bolts 6 of the busbar clamp 1 passes through the through holes 7 of the transition plate 4, they are fastened to the transition plate 4 by nuts 5, so as to realize the connection between the busbar clamp 1 and the transition plate 4.

[0025] Furthermore, the two through holes 7 on the transition plate 4 are designed as elongated oval shapes, which facilitates adaptive adjustment of different busbar clamp specifications on the transition plate 4.

[0026] Furthermore, the post insulator 3 and the transition plate 4 are connected by bolts; the post insulator 3 has multiple threaded holes evenly distributed at the center of its top, and the transition plate 4 is provided with countersunk holes 8 that correspond one-to-one with the threaded holes on the top of the post insulator 3. The connection between the transition plate 4 and the post insulator 3 is achieved by passing bolts through the countersunk holes 8 of the transition plate 4 and the threaded holes of the post insulator 3.

[0027] Furthermore, the number of countersunk holes 8 on the transition plate 4 is equal to the number of threaded holes on the top of the post insulator 3; preferably, the number of countersunk holes 8 on the transition plate 4 is four and they are evenly distributed in the central area of ​​the transition plate 4.

[0028] Furthermore, an anchor bolt is installed at each of the four corners of the base of the post insulator 3 to fix it to the horizontal plane and ensure stable fixation.

[0029] The key design feature of this invention lies in the effective connection and fixation between the clamp and the insulator for high-current busbars, thus solving the problem of effectively securing high-current busbars to the insulator. It should be noted that if the conductor diameter is below 170mm, the clamp can be directly used with the insulator without the need for a transition plate.
