Description

Technical Field

[0001] This utility model relates to an electrical component, specifically to a corrosion-resistant and wind-resistant pipe nut. Background Technology

[0002] Tubular busbars achieve efficient power transmission by optimizing electric field distribution, improving current transmission characteristics, and enhancing heat dissipation. Through a hollow metal tube structure, tubular busbars enable high-current efficient transmission. Their cylindrical design ensures uniform electric field distribution and low skin effect loss. Combined with multi-layer insulation and coaxial shielding, they significantly improve current carrying capacity and weather resistance. They are widely used in high-voltage substations, power plants, and new energy power plants, and are especially suitable for situations with limited space, high humidity, salt spray corrosion, or electromagnetic interference resistance. They can still operate stably in extreme environments, effectively solving problems such as electric field distortion and complex installation of traditional rectangular busbars.

[0003] In the prior art, patent number 202320896789.8 discloses an electromagnetically shielded tubular busbar for substations. This utility model discloses an electromagnetically shielded tubular busbar for substations, applicable in the substation field. It includes a tubular busbar body, a buffer mechanism on the outer surface of the body, a moisture-proof layer on the outer surface of the buffer mechanism, an electromagnetic shielding layer on the outer surface of the moisture-proof layer, an insulating layer on the outer surface of the shielding layer, and a support mechanism on the outer surface of the insulating layer. By using a copper shielding layer, the skin depth of copper is minimized, and using copper as the material reduces the thickness of the shielding layer, resulting in higher economy and applicability. Through the buffer mechanism, when the tubular busbar is subjected to external forces, the buffer ring is first affected, causing it to deform and dissipate some of the force. Then, the deformation of the buffer ring causes the buffer cross plate to deform, further dissipating the external force and preventing it from affecting the tubular busbar body.

[0004] Although existing tubular busbars can relieve external forces and prevent them from affecting the busbar body, they also have the problem of not being able to secure the tubular busbars properly. Utility Model Content

[0005] In order to overcome the shortcomings of the existing tubular busbar fixing assembly which is not stable enough, this utility model provides a corrosion-resistant and wind-resistant tubular busbar.

[0006] This utility model is achieved using the following technical solution: a corrosion-resistant and wind-resistant duct jack, comprising a duct jack body, the exterior of which is covered with an external flame-retardant component, the external flame-retardant component being a flame-retardant insulating material coating; a central channel on the duct jack body, the central channel being a hollow channel through which current passes; an assembly component at the bottom of the duct jack body, the assembly component being an assembly base, the assembly base having a locking part; an assembly kit on the assembly base, the assembly kit being divided into a left assembly kit and a right assembly kit; a circular hole on the assembly base; and a bottom support base at the bottom of the assembly kit, the bottom support base and the base being assembled and connected to each other.

[0007] The assembly base is provided with an assembly slot for bottom assembly, and a side plate is provided on the assembly slot, with the side plate located on one side of the assembly slot.

[0008] The assembly slot is provided with an assembly space, and a movable valve block is mounted on the assembly slot. The movable valve block is inserted into the assembly space within the assembly slot.

[0009] The movable valve block is provided with a bottom support rod at its bottom, and the movable valve block is provided with a threaded hole at its bottom for further locking the bottom support rod.

[0010] The bottom support rod has a connecting thread on one side, and the bottom support rod is inserted into the threaded hole. The bottom support rod and the movable valve block are assembled by means of the thread.

[0011] The locking part is a locking pin, which passes through the assembly. The inner wall of the assembly is provided with a sealing and anti-slip rubber pad, and the outer surface of the rubber pad is provided with anti-slip particles.

[0012] Compared to existing technologies, the hollow tube busbar has a flame-retardant and insulating coating, which effectively improves current transmission efficiency and fire safety. The middle channel serves as a current path, reducing resistance loss. Meanwhile, the external coating provides both corrosion protection and flame retardancy. The assembly base adopts a split left and right assembly structure, which, together with locking pins and a seal with anti-slip granular pads, enables quick installation and positioning. The locking pins further prevent loosening or displacement between the assembly and the tube busbar.

[0013] The threaded assembly structure of the movable valve block and the bottom support rod enhances the stability of the components inside the assembly slot. The overall structure can maintain reliable electrical performance and mechanical strength even in extreme environments. Combined with the cooperation of the split assembly and locking pins, the assembly of the bottom support rod and the movable valve block is more convenient, significantly improving the vibration resistance. It is suitable for strong wind and sand and highly corrosive environments such as wind farms and coastal substations. The movable assembly of the movable valve block and the bottom support rod facilitates the disassembly and assembly of the main pipe body and the bottom support rod. Attached Figure Description
