Description

Technical Field

[0001] The utility model relates to the field of protective covers, and more specifically to a protective cover for connecting a tubular busbar bridge. Background Art

[0002] The tubular busbar is a transmission device that efficiently transmits high-voltage current. Compared with the traditional rectangular busbar, the tubular busbar has the characteristics of good skin effect, large current carrying capacity per unit cross-section, good heat dissipation conditions, large allowable stress, large span, high mechanical strength, strong electrical insulation performance, high stability of the main insulation material, and reasonable insulation process. It can effectively ensure the power supply reliability of the transmission and transformation network.

[0037] Embodiment 2:

[0038] In view of the above embodiment 1, for further description, refer to Figure 3-Figure 5The sealing plug 4 is a conical structure made of rubber material. The inner wall diameter of the pipeline sleeve channel 403 is equal to the outer wall diameter of the tubular busbar 3. The outer wall diameter of the cone portion of the sealing plug 4 is smaller than the inner wall diameter of the inlet and outlet hole 101. The outer wall diameter of the root portion of the sealing plug 4 is larger than the inner wall diameter of the inlet and outlet hole 101.
