Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of busbar installation, and particularly relates to a bracket for monitoring the displacement of a busbar. Background Art
[0002] With the booming development of the power equipment industry, the forms of support for GIS equipment have become diverse, and among them, the rolling bracket is the most commonly used bracket form. Especially in GIS equipment, the rolling bracket is widely used for busbar support. The busbar can freely displace along the axial direction on the bracket through the rollers of the rolling bracket, fully releasing the internal force generated by thermal expansion and contraction, and protecting the safety of the equipment. At the same time, the rollers on the rolling bracket are marked with scales, and the specific value of the displacement of the busbar due to thermal expansion and contraction can also be monitored, which has reference value for the operation and maintenance of the whole station. However, after the rollers of the rolling bracket have been operating for a period of time, the rollers may not roll due to factors such as aging of the internal parts of the rollers caused by wind, sun, and rain. As a result, the scale readings on the rollers are inaccurate, and the displacement monitoring function is lost. At the same time, because GIS equipment is usually located at a high place, it is inconvenient to read the data, and the readings are considered inaccurate. Summary of the Invention

[0023] The following further describes the implementation of the present utility model with reference to the drawings.
[0024] As Figures 1-3As shown in the figure, an embodiment of the present utility model provides a bracket for busbar displacement monitoring, including: a bracket body, two sets of pipe clamps, two annular screws 1, and a scale 5.
[0025] Installation holes for the annular screws 1 are reserved at both ends of the bracket body. Both ends of each annular screw 1 are respectively connected to both ends of the bracket body to ensure that the distance between the two annular screws 1 is a fixed value. The busbar cylinder is placed between the annular screw and the bracket body, and there is a certain gap between the annular screw 1 and the busbar cylinder.
[0026] Each set of pipe clamps includes a first pipe clamp 3 and a second pipe clamp 4, which are combined and sleeved on one side of each annular screw 1 and fixed; the scale 5 is fixed between the two sets of pipe clamps with bolts. The positions of the two sets of pipe clamps on the annular screw 1 are the same, so that the scale 5 is parallel to the axial direction of the busbar cylinder. The scale 5 is used for busbar displacement monitoring. Initially, a line can be drawn on the busbar corresponding to the scale markings as a mark. When the busbar expands and contracts due to heat, the specific value of the displacement can be obtained by checking the difference between the busbar mark and the corresponding scale on the scale.
[0027] A camera is also fixed on the annular screw 1 so that the camera is aligned with the scale 5 and can capture the scale 5 and the busbar cylinder; this camera is also connected to external devices (such as a computer) to process and save the information captured by the camera, and monitor the busbar displacement in real time.
[0028] The bracket body includes a base 10, a support bracket 2, a roller 6, a roller shaft 11, a bearing bracket I 7-1, a bearing bracket II 7-2, and a split pin 9. Two support brackets 2 are provided on the base 10, and a bearing bracket I 7-1 and a bearing bracket II 7-2 are provided on each support bracket 2. The bearing bracket II 7-2 is triangular, with the bottom surface fixed on the support bracket 2. The lower end of the bearing bracket I 7-1 is perpendicular to the support bracket 2 and fixed thereto, and the upper end of the bearing bracket I 7-1 is parallel to one side of the bearing bracket II 7-2. The roller shaft 11 passes through the upper end of the bearing bracket I 7-1, the roller 6, and the side of the bearing bracket II 7-2 parallel to the upper end of the bearing bracket I 7-1 in sequence. A gasket 8 is also provided between the roller 6 and the bearing brackets I 7-1 and II 7-2, and the gasket 8 can prevent the roller from wearing the bearing bracket during operation. The roller 6 and the bearing bracket II 7-2 are parallel to the bearing bracket I 7-1. One end of the roller shaft 11 has a larger diameter than the through hole, and a split pin 9 is provided at the other end. The surface of the roller 6 is in contact with the surface of the busbar cylinder. Scales are marked on the roller 6 for busbar displacement monitoring.
[0029] All connections are made by bolts and nuts.
[0030] When the utility model is actually used, the busbar cylinder body is placed on the roller 6 of the support body. The roller 6 is provided with scales. Then, the annular screw 1 is sleeved on the busbar cylinder body for limiting, ensuring that there is a certain gap between the annular screw 1 and the busbar cylinder body. The busbar cylinder body slides smoothly on the roller 6 without jamming. The scale 5 is fixed on the two pipe clip groups of the annular screw 1 through bolts, and a line is drawn on the busbar corresponding to the scale of the scale as a mark.
[0031] During subsequent maintenance, the displacement value of the busbar can be read through the roller, or the displacement value can be read through the relative relationship between the scale and the marking line.
[0032] The embodiment of the utility model provides a variety of busbar displacement monitoring means, which can prevent the monitoring from failing due to the passage of time, and is convenient for on-site operation and maintenance in the later stage.
[0033] The above is only the preferred embodiment of the utility model.
