Description

Technical Field

[0001] This utility model relates to the field of spacer bars, and more particularly to a substation spacer bar. Background Technology

[0002] Spacers are devices used to maintain proper spacing between power lines in a power transmission system. They are typically installed on transmission towers or poles to ensure sufficient space between the wires and prevent wire contact and short circuits caused by weather conditions, vibrations, or other factors. The design and material selection of spacers depend on a variety of factors, including voltage levels, environmental conditions, and the physical properties of the wires. They play a crucial role in power systems and help improve the reliability and safety of transmission lines.

[0003] There is currently a Chinese patent document CN202222615699.5, which discloses a four-split conductor spacer for phase-to-ground spacers. The spacer includes a spacer frame. The inner walls of both sides of the spacer frame are fixedly connected to the two ends of a support rod I. The middle of support rod I is fixedly connected to the middle of a support rod II. The two ends of support rod II are fixedly connected to the other two inner walls of the spacer frame. Several rotating columns are rotatably connected to the outer periphery of the spacer frame. A threaded rod is fixedly connected to the end of each rotating column away from the spacer frame. An internal threaded cylinder is fitted onto the threaded rod through a threaded structure. A wire clamp is fixedly connected to the end of the internal threaded cylinder away from the threaded rod. By rotating the threaded rod in conjunction with the internal threaded cylinder, the extension length of the wire clamp can be adjusted, thereby clamping transmission lines with different spacings. This facilitates the installation of the spacer and reduces the need for manual pulling of the transmission lines. Then, by rotating the threaded rod in the opposite direction, the wire clamp is retracted, thereby adjusting the spacing between the transmission lines to a suitable distance. Utility Model Content

[0004] However, the above-mentioned patent has certain defects in use. In outdoor environments, the spacer bar is susceptible to wind and rain erosion due to the adjustment of the clamp length via the threaded rod, which leads to thread wear and affects the service life and stability of the spacer bar.

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a substation bay bar.

[0006] This utility model is achieved using the following technical solution:

[0007] A substation bay bar, including

[0008] A substation spacer bar includes a frame and two side plates, characterized in that: the two side plates are connected in parallel on both sides of the frame, the two side plates are provided with multiple limiting grooves, multiple rotating sleeves are provided on one side of the multiple limiting grooves, and multiple spacer bars are provided between the two side plates;

[0009] Each of the multiple spacer bars has a pin on both sides. The pin is movably installed in the rotating sleeve. The peripheral wall of the pin is threaded and a nut is connected to the thread. The nut is located on one side of the rotating sleeve and a washer is provided between the nut and the rotating sleeve.

[0010] Each of the multiple spacer bars has a pin on both sides, and the pin is located next to the pin shaft, which is movably installed in multiple limiting grooves.

[0011] As a preferred embodiment of this utility model, the end of the spacer bar is provided with a lower wire clamp, one side of the lower wire clamp is provided with a hinge, the other end of the link is connected to an upper wire clamp, and both the upper wire clamp and the lower wire clamp are provided with threaded holes, and fixing screws are movably connected in the threaded holes.

[0012] As a preferred embodiment of this utility model, an insulating frame is provided inside the frame, and the insulating clamp is fixed inside the frame in an X shape.

[0013] As a preferred embodiment of this utility model, the outer peripheral wall of the frame is provided with a plurality of reinforcing ribs, and a limiting block is provided on both sides of the plurality of reinforcing ribs, and the limiting block is located on one side of the spacer rod.

[0014] As a preferred embodiment of this utility model, both the upper and lower wire clamps are provided with insulating rubber rings on their inner walls.

[0015] As a preferred embodiment of this utility model, the two side plates are provided with multiple through holes.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. By providing multiple limiting slots and rotating sleeves on the side plates on both sides of the frame, the spacer bar can be flexibly adjusted by the pin and the plug. In actual use, the pin is installed into the rotating sleeve and the plug is installed into the limiting slot. It is then tightened by nuts and washers to ensure that the pin is located in the rotating sleeve, thus achieving rapid positioning and stabilization of the spacer bar. In outdoor environments, when the line swings due to strong winds, the plug self-adjusts in the limiting slot to ensure that the spacer bar always remains stable.

[0018] 2. The upper clamp is connected to the lower clamp via a hinge. During installation, simply align the cable in the lower clamp, flip the upper clamp to fix it via the hinge, and then tighten it with a fixing screw through the screw hole. This is efficient and convenient. At the same time, the insulating rubber rings on the inner walls of the upper and lower clamps effectively prevent cable wear and extend service life.

[0019] 3. An insulating frame is installed inside the frame, fixed in an X shape, to enhance structural stability, prevent current leakage, and ensure safe operation. Multiple reinforcing ribs are installed on the outer perimeter wall of the frame, which, together with the limiting blocks and spacers, further enhance the overall wind resistance and ensure the reliability of the equipment in severe weather.

[0026] Example:

[0027] Please see Figures 1-4 A substation bay bar, comprising:

[0028] A substation spacer bar includes a frame 1 and two side plates 2, characterized in that: the two side plates 2 are connected in parallel on both sides of the frame 1, the two side plates 2 are provided with a plurality of limiting grooves 4, a plurality of rotating sleeves 5 are provided on one side of the plurality of limiting grooves 4, and a plurality of spacer bars 9 are provided between the two side plates 2.

At the same time, limiting blocks 8 are provided on both sides of the reinforcing ribs 7. The limiting blocks 8 are located on one side of the spacer 9 to ensure that the spacer 9 will not exceed the set range when swinging.

[0038] Specifically, the inner walls of both the upper clamp 16 and the lower clamp 15 are provided with insulating rubber rings 20.

[0039] In this embodiment, the insulating rubber rings 20 on the inner walls of the upper clamp 16 and the lower clamp 15 effectively prevent cable wear.

[0040] Specifically, the two side plates 2 are provided with multiple through holes 6.

[0041] In this embodiment, both side plates 2 are provided with multiple through holes 6. The multiple through holes 6 are used to install auxiliary components and facilitate the adjustment of the position of the spacer 9. The through hole 6 design ensures ventilation and heat dissipation.
