Description

Technical Field

[0001] This utility model relates to the field of substation construction, and more specifically, to a busbar connection and fastening structure for substations. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of the electrical energy generated by generators and feed it into the high-voltage power grid. Busbars refer to the connections between different voltage distribution devices in a substation, as well as the connections between transformers and other electrical equipment and their corresponding distribution devices. They mostly use bare conductors or stranded wires with rectangular or circular cross-sections. The function of busbars is to collect, distribute, and transmit electrical energy. Substation busbars are generally tubular busbars. During installation, a support frame must first be erected, then the fastening devices must be installed on the support frame, and finally the tubular busbars must be installed on the fastening devices.

[0003] Existing fastening devices are usually fixed and cannot be freely adjusted. Therefore, when installing tubular busbars, if the required spacing is different, it is necessary to replace the fastening device with one that matches the current one. This limits the applicability of the device. Utility Model Content

[0004] This utility model provides a busbar connection and fastening structure for substations, which allows for free adjustment of the spacing according to actual usage conditions and has strong applicability.

[0005] The technical solution adopted in this utility model is as follows:

[0006] The system includes a guide rail body, with a first guide rail on its top. At least one first slider is slidably connected within the first guide rail. A fastening assembly is sequentially mounted on the top of the first slider via a moving plate and a base. A through groove is formed on one side wall of the guide rail body, communicating with the cavity of the first guide rail. An extension plate is slidably installed within the through groove, with its inner end fixed to the first slider and its outer end connected to an auxiliary plate. A clamping plate is provided below the extension plate, with its outer end adapted to and slidably connected to a second guide rail on the auxiliary plate via a second slider. A rubber fixing plug is installed on the inner end face of the clamping plate, with its top tightly contacting a groove on the bottom surface of the guide rail body. The upper end of a threaded rod is rotatably connected to the bottom surface of the extension plate, and its lower end is threadedly connected to the clamping plate.

[0007] The fastening assembly includes a lower clamp and an upper clamp. The lower clamp is fixed to the top of the base, and the upper clamp is disposed on the top of the lower clamp. The lower clamp and the upper clamp are connected as one unit by integrally formed connecting lugs on both sides of their respective sides.

[0008] The bottom of the guide rail body is equipped with a lifting component.

[0009] The lifting assembly includes a sliding column and a sleeve column. The sliding column is slidably connected inside the sleeve column. The top of the sliding column is fixedly connected to the bottom surface of the guide rail body, while the bottom of the sleeve column is fixedly connected to the mounting support. The sliding column has evenly spaced threaded holes, and the sleeve column is threadedly connected to a locking screw. The threaded holes and the locking screw are compatible.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. By setting a push-moving plate, the moving plate drives the first slider to slide along the first guide rail. At the same time, the moving plate drives the base, and the base drives the fastening component at the top to move it to the required position. Then, the threaded rod is rotated, which drives the clamping plate. The clamping plate drives the rubber fixing plug, so that the clamping plate clamps the guide rail body. At this time, the rubber fixing plug deforms and then inserts into the slot, thus completing the fixation. This realizes that the busbar connection fastening structure of this substation can freely adjust the spacing according to the actual use. In this way, when installing tubular busbars, even if the required spacing is different, it can be freely adjusted to the required spacing. It has strong applicability and solves the problem that the fastening device in the existing technology is usually fixed and cannot be freely adjusted. Therefore, when installing tubular busbars, when the required spacing is different, it is necessary to replace the matching fastening device, which has a small range of application and certain limitations.

[0012] 2. By setting a push-mounting support, the mounting support drives the sleeve column, causing the sleeve column to slide on the outer wall of the sliding column. After adjusting to the required height, the sleeve column and the sliding column are fixed with a locking screw, thus realizing the height adjustment of this fastening device.
