AI Technical Summary
The anti-floating bracket structure of the traditional three-phase common box GIL busbar is large and occupies a large corridor space, which is not conducive to the replacement and maintenance of the busbar.
The bracket main body and large screw structure are adopted. The bracket main body is installed in the corridor, and the three-phase common box GIL busbar is supported on the bracket main body. The large screw is parallel to the support main hole and passes through the hole. Both ends are connected to the busbar, allowing the busbar to move in the axial and radial directions, reducing the use of transverse and vertical beams.
While achieving anti-floating effect, it reduces the equipment size, increases the clean space of the corridor, facilitates installation and maintenance, and saves costs.

Abstract
Description
Technical Field
[0001] The utility model relates to GIL technology, in particular to an anti-floating bracket for a three-phase coaxial GIL busbar. Background Art
[0002] The anti-floating bracket of the traditional three-phase coaxial GIL busbar includes a transverse beam and a vertical beam. The three-phase coaxial GIL busbar is blocked from above by the transverse beam to achieve the anti-floating effect, as follows Figure 1 shown. The structure is large, occupying a large corridor space, which is not conducive to the subsequent replacement and maintenance of the busbar. Content of the Utility Model
[0003] To solve the above problems, the utility model provides an anti-floating bracket for a three-phase coaxial GIL busbar, which realizes the anti-floating effect and allows the three-phase coaxial busbar to move in both axial and radial directions. Of course, it can also be used for a three-phase separated GIL busbar.
[0004] The technical solution of the utility model is as follows:
[0005] An anti-floating bracket for a three-phase coaxial GIL busbar, the anti-floating bracket includes a bracket body and a large screw rod. The bracket body is installed in the corridor and located below the three-phase coaxial GIL busbar. The three-phase coaxial GIL busbar is supported on the bracket body. The bracket body is provided with holes. The large screw rod is parallel to the three-phase coaxial GIL busbar, passes through the holes on the bracket body, extends out at both ends and is connected to the three-phase coaxial GIL busbar. A gap is left between the large screw rod and the holes on the bracket body.
[0006] When the corridor is flooded and the busbar floats, the three-phase coaxial GIL busbar is pulled by the bracket body through the large screw rod. When the three-phase coaxial GIL busbar moves axially, the large screw rod moves axially in the holes on the bracket body. When the three-phase coaxial GIL busbar moves radially, the large screw rod moves radially in the holes on the bracket body (utilizing the gap between the large screw rod and the holes on the bracket body).
[0007] There are two large screw rods in total, and the two large screw rods are arranged side by side; the two large screw rods share one hole or different holes; the two large screw rods can bear greater tensile force.
[0008] The holes on the bracket body are rectangular holes.
[0009] A saddle is installed on the three-phase coaxial GIL busbar, and the saddle is placed on the bracket body.
[0010] Fixing blocks are installed at both ends of the large screw rod and are connected to the saddle through the fixing blocks. The fixing blocks are fixed at the bottom of the saddle, and they cooperate with the bracket body to form an axial movement limit for the three-phase coaxial GIL busbar.
[0011] The utility model has the following beneficial effects:
[0012] 1. Miniaturization: Without the horizontal beam and vertical beam, the size of the anti-floating bracket is reduced, thereby reducing the size of the equipment, increasing the net space of the corridor, facilitating installation and maintenance; at the same time, the size of the corridor can also be reduced, saving the civil engineering cost.
[0013] 2. Lightweight: Without the horizontal beam and vertical beam, the cost of the steel bracket is saved, and it is also convenient for installation.
[0014] 3. Diversified functions: The anti-floating function is realized without adding any accessories, and at the same time, the limited axial movement and limited radial movement are realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] As Figure 2-3 shown, an anti-floating bracket for a three-phase coaxial GIL busbar, the anti-floating bracket includes a bracket body 1 and two large screws 2. The bracket body 1 is installed in the corridor and is located below the three-phase coaxial GIL busbar 3. A saddle 4 is installed on the three-phase coaxial GIL busbar (connected to the three-phase coaxial GIL busbar 3 through a hoop 5). The saddle 4 is placed on the bracket body 1. Two rectangular holes 6 are arranged side by side on the bracket body 1. The two large screws 2 are parallel to the three-phase coaxial GIL busbar 3, and respectively pass through the two rectangular holes 6 and extend at both ends. There is a gap between the large screw 2 and the rectangular hole 5 (to realize the radial limit of the three-phase coaxial GIL busbar). Fixed blocks 7 are installed at both ends of the large screw 2 and are connected to the saddle 4 through the fixed blocks 7. The fixed blocks 7 are fixed at the bottom of the saddle 4 and cooperate with the bracket body 1 to form the axial movement limit of the three-phase coaxial GIL busbar 3.
