Description

Technical Field

[0001] The utility model belongs to the technical field of sectional insulators, and relates to a fixing structure for a current-carrying plate of a sectional insulator. Background Art

[0002] In recent years, rail transit in China has developed rapidly. The normal operation of rail transit such as high-speed railways and light rails depends on the catenary that provides power. The catenary includes a sectional insulator and a contact wire, and the sectional insulator includes a current-carrying plate.

[0003] For the existing fixing structure of the current-carrying plate, for example, a Chinese patent document discloses a rigid sectional insulator [Patent No.: 201120244587.2; Application Publication No.: CN202152015U]. This rigid sectional insulator includes a first connecting member and a second connecting member for connecting a contact busbar. A main insulating rod is connected between the first connecting member and the second connecting member. Each side of the first connecting member is provided with a current-carrying slideway. One end of each current-carrying slideway contacts the first connecting member, and the other end extends to the side of the second connecting member and is spaced from the second connecting member by a certain distance. The current-carrying slideway is fixed to the first connecting member and the second connecting member through an adjusting mechanism capable of adjusting the relative position of the current-carrying slideway and the main insulating rod.

[0004] The sectional insulator of this structure includes two current-carrying slideways. One ends of the two current-carrying slideways are indented inward to be fixedly connected to the contact wire, and the other ends open outward. The middle of the two current-carrying slideways is connected by a straight rod-shaped connecting rod, and the middle of the connecting rod is connected to an inner positioning plate to improve the stability of the two current-carrying slideways. However, for the sectional insulator of this structure, the three points where the connecting rod is connected to the two current-carrying slideways and the inner positioning plate are on the same straight line. During actual use, there is a problem that the two current-carrying slideways and the connecting rod shake simultaneously, resulting in the stability of the two current-carrying slideways still not being high enough. Summary of the Invention

[0005] The purpose of the utility model is to address the above problems existing in the prior art, and propose a fixing structure for a current-carrying plate of a sectional insulator, and the technical problem to be solved is how to improve the stability of the current-carrying plate.

[0006] The purpose of the utility model can be achieved by the following technical solutions: A fixing structure for a current-carrying plate of a sectional insulator. The sectional insulator includes a joint located between the two current-carrying plates and used for connecting an insulator. One ends of the two current-carrying plates are fixedly connected to the contact wire, and the joint is connected to the contact wire. The fixing structure is characterized in that the fixing structure includes a fixing plate and two connecting plates fixedly connected to the fixing plate and spreading outwards in a wing shape. The fixing plate is fixedly connected to the joint, and the outer ends of the two connecting plates are respectively connected to the middle parts of the two current-carrying plates.

[0007] The fixed plate and the two connecting plates are in the shape of a wing, similar to a V shape. The fixed plate is connected to the joint, and the outer ends of the two connecting plates are connected to the middle of the flow deflector. That is, the three connection points are arranged in a triangle, having the strongest rigidity and improving the stability of the flow deflector. The joint is connected to the insulator, and the joints are relatively positioned. The two flow deflectors are connected to the joint through the fixed plate and the two connecting plates, improving the stability.

[0008] In the above-mentioned fixed structure of the flow deflector of a sectional insulator, the fixed structure further includes two connecting members and two fastening members. The two connecting members are respectively connected to the middle parts of the two flow deflectors, and the outer ends of the connecting plates are fixedly connected to the connecting members through the fastening members. The setting of the connecting members makes the middle part of the flow deflector have a connection position, so that the structure of the flow deflector does not need to be changed; the connecting member and the flow deflector can be fixedly connected or have a certain buffer margin.

[0009] In the above-mentioned fixed structure of the flow deflector of a sectional insulator, the inner ends of the two connecting plates are respectively connected to the side edges on both sides of the fixed plate, and the two connecting plates are symmetrically arranged. The fixed plate and the two connecting plates are of an integral structure. The integral structure and the symmetrical arrangement make the stability of the flow deflector good.

[0010] In the above-mentioned fixed structure of the flow deflector of a sectional insulator, the fixed plate is fixedly connected to the top of the joint, and the fixed plate and the two connecting plates are both located above the flow deflector. In this structure, there is a height difference between the fixed plate and the two connecting plates and the flow deflector, and they are staggeredly arranged, having a better buffering effect, thereby improving the stability of the flow deflector.

[0011] In the above-mentioned fixed structure of the flow deflector of a sectional insulator, the top surface of the connecting plate is inclined downward along the direction from its inner end to its outer end. In this structure, it is not easy for snow and ice to accumulate on the connecting plate.

[0012] In the above-mentioned fixed structure of the flow deflector of a sectional insulator, the outer end of the connecting plate has an extension portion arranged outward, and a lifting ring is fixedly connected to the extension portion. The connecting plate and the fixed plate have sufficient strength. The setting of the lifting ring can directly lift the entire sectional insulator through a sling, making the fixed structure have a dual function.

[0013] Compared with the prior art, the fixed structure of the flow deflector of a sectional insulator provided by the present utility model has the following advantages:

[0014] 1. The fixed plate and the two connecting plates of this fixed structure are in the shape of a wing. The fixed plate is connected to the joint, and the outer ends of the two connecting plates are connected to the middle of the flow deflector. That is, the three connection points are arranged in a triangle, having the strongest rigidity and improving the stability of the flow deflector.

[0015] 2. A lifting ring is provided at the outer end of the connecting plate of the fixing structure, and the entire sectional insulator can be directly lifted by a sling, enabling the fixing structure to have a dual function. Description of the Drawings
