[0040] figure 1 A schematic longitudinal sectional view of an electrical connection assembly according to a first exemplary embodiment of the present invention is shown.

[0041] Such as figure 1 As shown, in the present invention, the electrical connection assembly mainly includes tubular busbars 10 , 20 , an outer conduit 30 and an inner liner 40 accommodated in the lumen of the outer conduit 30 . In order to be able to conduct electricity, both the outer conduit 30 and the inner liner 40 are made of electrically conductive materials.

[0042] In an exemplary embodiment of the present invention, the hardness of the inner liner 40 is much greater than that of the outer conduit 30 . In this way, the inner liner 40 can provide enough supporting strength for the outer conduit 30 to prevent the outer conduit 30 from excessive deformation or damage under the action of external crimping force (to be described later).

Figure 7 It shows a schematic longitudinal sectional view of the electrical connection assembly and a tubular busbar sleeved together according to the second exemplary embodiment of the present invention.

[0058] Such as Figure 6 As shown, the electrical connection assembly of the second embodiment mainly includes a tubular bus bar 100 , an outer conduit 300 and an inner liner 400 accommodated in the lumen of the outer conduit 300 . In order to be able to conduct electricity, both the outer conduit 300 and the inner liner 400 are made of conductive materials.

[0059] In an exemplary embodiment of the present invention, the hardness of the inner liner 400 is much greater than that of the outer catheter 300 . In this way, the inner liner 400 can provide sufficient supporting strength for the outer cathe...

Abstract

The invention discloses an electric connection assembly electrically connected with a tubular bus. The electric connection assembly comprises an outer guide pipe provided with a lining pipe, wherein at least one end of the outer guide pipe with the lining pipe is inserted into the tubular bus, and the tubular bus and the insertion end of the outer guide pipe are in pressure welding together on the outer peripheral surface of the tubular bus in a multipoint pressure-welding mode. Compared with the prior art, the electric connection assembly has the advantages of simple structure, less parts, easy manufacture, low cost, convenience for site installation and simpleness in operation. In addition, the tubular bus and the electric connection assembly are in pressure welding together in a hydraulic point pressure mode, so that the outer wall of the electric connection assembly is in tight contact with the inner wall of the tubular bus; and the contact surface is large in pressure and the reliability of electric connection is ensured.

Description

technical field [0001] The invention relates to an electrical connection assembly, in particular to a connection device for electrical connection with a tubular busbar, especially suitable for electrical connection with a large cross-section tubular busbar. Background technique [0002] In various high-voltage places such as power plants, distribution substations, and large-scale industrial and mining fields, tubular busbars that transmit power frequency and high currents are required. This high-voltage tubular busbar has a large cross-section. In the prior art, for the connection operation of such a large cross-section high-pressure tubular busbar, the following three traditional connection methods are generally adopted: [0003] 1) Hoop connection method [0004] The hoop connection method hugs the tubular busbar from the outside. The mechanical structure is complex, the size is large, and the shape is irregular. The outer covering shielding layer is not firm, and it is n...
