[0001] The utility model relates to the technical field of tubular busbars, in particular to a tubular busbar which is convenient for connection and installation. Background Art

[0002] The tubular busbar is a commonly used conductive device in power transmission systems. It is usually composed of a metal pipe and is used to transmit electric energy from a power station to various users or between different power stations. The tubular busbar is usually used in medium and high voltage power transmission systems. Its advantages include lower resistance, lower inductance and higher current capacity. This allows the tubular busbar to reduce energy loss during power transmission and can withstand a larger current load. In addition, the tubular busbar also has good mechanical strength and corrosion resistance, which enables it to operate stably under various environmental conditions.

[0023] In this embodiment, when connecting and installing, the different structures at both ends of the first bus tube 1 and the second bus tube 2 are placed relative to each other. For example, the elastic clamp 3 at one end of the first bus tube 1 faces the second sealing disk 5 at one end of the second bus tube 2, and then the elastic clamp 3 set at the outer ring of the first sealing disk 4 is inserted into the groove 6 outside the ring of the second sealing disk 5. When inserted, the elastic clamp 3 is elastically compressed, and elastically expanded after passing through the groove 6, so that it can be clamped on the outer side of the back side of the second sealing disk 5 close to the groove 6, so that the connection and installation speed is faster.

[0024] like Figure 3 and Figure 4 As shown, a nut sleeve 7 is sleeved on one end of the back side of the first busbar tube 1 and the second busbar tube 2 close to the first sealing disk 4, a thread groove 8 is provided on the outer wall of the elastic clamp 3, the nut sleeve 7 is threadedly connected with the thread groove 8, rod sleeves 9 are symmetrically arranged on the outer walls of both sides of the nut sleeve 7, and a retaining ring 10 is fixedly connected to the outer wall of one end of the back side of the first busbar tube 1 and the second busbar tube 2 close to the nut sleeve 7, and the outer diameter of the retaining ring 10 is larger than the inner diameter of the nut sleeve 7;

[0025] In this embodiment, when the elastic clamp 3 passes through the groove 6 and is clamped on the outside of the second sealing disk 5, a tool is used to be sleeved in any one of the rod sleeves 9, and then the tool is rotated. The tool drives the nut sleeve 7 to rotate through the rod sleeve 9 until the nut sleeve 7 is threadedly sleeved with the elastic clamp 3. The nut sleeve 7 is used to connect and fix the elastic clamp 3. After the connection and installation, the first busbar tube 1 and the second busbar tube 2 are not easy to fall off, thereby improving the structural stability after the connection.
