Title:
BUSBAR UNIT AND PIPELINE BUSBAR
Document Type and Number:
WIPO Patent Application WO/2021/000552
Kind Code:
A1
Abstract:
Disclosed are a busbar unit (10, 20) and a pipeline busbar, relating to the technical field of GIL. The busbar unit (10, 20) comprises a busbar barrel body and a conducting rod (13); one end of the busbar barrel body is fixedly provided with a fixing insulator relative to the busbar barrel body; two axial ends of the fixing insulator are respectively provided with a fixing connection seat and a plug-in connection seat; the fixing connection seat allows the corresponding conducting rod (13) in the busbar unit (10, 20) or adjacent busbar units (10, 20) to be fixed and connected in a conductive manner; and the plug-in connection seat allows the corresponding conducting rod (13) in the busbar unit (10, 20) or adjacent busbar units (10, 20) to achieve plug-in cooperation and conductive connection. The fixing connection seat and the plug-in connection seat arranged on the two sides of the insulator in the busbar unit (10, 20) enable a conducting rod (13) in the prior art to be changed into a form with one end fixed and the other end telescopic, and the telescopic movement of only one end of the conducting rod (13) is limited, such that the whole unit can still adapt to the temperature change by means of self-telescopic deformation, and the problems that the plug-in length of the conducting rod (13) is too short and that the conducting rod may even fall off during heat expansion and cold contraction can be effectively solved.
