Description

Technical Field

[0001] The utility model belongs to the technical field of pipe busbar fittings, and particularly relates to a telescopic self-adaptive flexible current-carrying pipe busbar fitting for a substation. Background Technique

[0002] Pipe busbar fittings are metal accessories widely used in power transmission and transformation lines. They are usually made of iron or aluminum and are collectively called fittings. There are many types of fittings with different uses. For example, various wire clamps for installing conductors, various hanging rings for forming insulator strings, various compression joints and repair pipes for connecting conductors, and various types of spacer dampers on bundled conductors. In addition, there are various types of guy wire fittings for poles and towers. These fittings need to consider the size matching with the conductors when in use.

[0003] Chinese Utility Model Patent CN217469398U discloses a pipe busbar connection fitting, including: a current-carrying body, a pipe busbar gland for inserting a pipe busbar is provided at the first end of the current-carrying body; a wiring board main body, the wiring board main body is connected to the second end of the current-carrying body through a universal joint; and a plurality of current-carrying welding wires, one ends of the plurality of current-carrying welding wires are respectively connected to the pipe busbar gland, and the other ends of the plurality of current-carrying welding wires are respectively connected to the wiring board main body. According to the pipe busbar connection fitting of the utility model, the current-carrying body and the wiring board main body can turn in any direction, effectively avoiding the connection fitting from breaking due to large stress, increasing the use range and prolonging the service life.

[0004] Through the use and installation of the above design of the universal joint, the angle between the current-carrying body and the wiring board main body can be flexibly adjusted and changed. However, in actual use, there are certain problems with the use of this design, specifically reflected in that the universal joint itself does not have an insulating supporting component, which easily causes the current guided inside the pipe busbar to pass through the universal joint and re-enter the wiring board main body. And after a long time, because the current continuously passes through the pipe busbar and the universal joint, the temperatures of both increase continuously, and the resistance values of the pipe busbar and the universal joint themselves increase continuously, resulting in the influence on the conductive effect of the equipment itself.

The present utility model provides the following embodiments.

[0027] As Figure 1 , Figure 2 and Figure 3 shown, a telescopic self-adaptive flexible current-carrying pipe bus fitting for a substation includes a pipe bus main body 1 and a power connection plate 2. The power connection plates 2 are symmetrically arranged on both sides of the pipe bus main body 1. A conductive mechanism 3 is fixedly installed between the power connection plate 2 and the pipe bus main body 1. Support sleeves 4 are symmetrically and fixedly installed at the ends of the pipe bus main body 1. The conductive mechanism 3 includes a connection end 31, a connection pipe 32, a fixing block 33, and an installation component 34. The connection ends 31 are symmetrically and fixedly installed on the side surfaces of the power connection plates 2. The connection pipe 32 is fixedly installed on the side surface of the connection end 31. The installation component 34 is sleeved outside the pipe bus main body 1. The fixing block 33 is fixedly installed on the upper surface of the installation component 34, and the fixing block 33 is fixedly connected to the connection pipe 32.

[0028] In use, by installing the pipe bus fitting between the devices that need circuit connection, through the use of the power connection plates 2 on both sides of the pipe bus main body 1, the pipe bus fitting is stably installed at the target position. Then, through the use of the power connection plates 2 and the conductive mechanism 3, the circuits between the devices are linked to assist in current transmission. During use, first, the two connection ends 31 are welded to the side surfaces of the power connection plates 2, and then through the cooperation of the connection pipe 32 and the fixing block 33, the circuit is ensured to be normal. After the subsequent current enters the interior of the connection pipe 32 through the power connection plate 2, the installation component 34 can guide the current into the interior of the pipe bus main body 1. Then, the current flows out through the conductive mechanism 3 and the power connection plate 2 on the other side to complete the current transmission, ensuring the stability during the operation of the device. And during use, by using the cooperation of the conductive mechanism 3 and the support sleeve 4, the originally integrated component of support and conduction is disassembled. The support sleeve 4 can provide stable support for the device main body to ensure the stability of the pipe bus main body 1 during use, while the conductive mechanism 3 mainly conveys the current received by the power connection plate 2 to complete the function differentiation.

[0029] As shown in the attached Figure 3As shown in the figure, in this embodiment, the mounting assembly 34 further includes an upper collar 341, a lower collar 342, a mounting screw groove 343, a mounting screw 344, and a mounting nut 345. The upper collar 341 is slidably mounted on the upper surface of the busbar main body 1, and the lower collar 342 is slidably mounted on the lower surface of the busbar main body 1. The upper collar 341 and the lower collar 342 are jointly provided with a mounting screw groove 343 inside. The mounting screw 344 is threadedly mounted inside the mounting screw groove 343, and the mounting nut 345 is threadedly mounted at the end of the mounting screw 344. During use, by sleeving the upper collar 341 and the lower collar 342 on the upper and lower sides of the outside of the busbar main body 1, and then through the combination of the upper collar 341 and the lower collar 342, the fixing of the overall frame of the mounting assembly 34 is completed. By using the mounting screw 344 and the mounting nut 345, the positions of the upper collar 341 and the lower collar 342 are reinforced, so that the mounting assembly 34 is stably attached to the outer surface of the busbar main body 1, completing the locking of the positions of the components. Moreover, the overall structure of the support sleeve 4 is the same as that of the conductive mechanism 3. A cover plate is additionally installed on the side of the support sleeve 4, so that when the support sleeve 4 assists in positioning the busbar main body 1, it can provide more stable support.

The fixed screw 531 is threadedly installed inside the insulating sleeve 532. During use, first, the fixed screw 531 is inserted into the insulating sleeve 532, and then the insulating sleeve 532 is respectively passed through the rotating groove 534 and the U-shaped groove 514. By using the limiting nut 533, the position of the insulating sleeve 532 itself is fixed, completing the limitation of the position of the rotating assembly 51 itself. Moreover, the presence of the insulating sleeve 532 can further block the current and strengthen the insulation effect of the device itself.
