Problems solved by technology

[0009] Therefore, the connection device in the current state of the art needs to have a large bush, thereby requiring a large amount of material, and its manufacturing cost is also increased accordingly
The large size of the connection also means that the overall size of the individual racks is larger and thus the substation itself is also larger

Embodiment Construction

[0034] figure 1 and figure 2 Shown is an electrical connection device 2 according to the invention, which connects two racks 4 and 4' together.

[0035] The two racks 4 and 4' are substantially identical to each other, only rack 4 being described here.

[0036] Frame 4 includes filled with such as sulfur hexafluoride (SF 6 ) of a dielectric gas and a set of busbars (not shown), which are set to be connected to a set of busbars of adjacent racks 12' to form a single set of busbars. The racks connected together in this way form a medium and high voltage distribution station.

[0037] In the following description, only the connection between two racks is described, but it will be clearly understood that the invention can be used in distribution substations with at least two racks, and in particular with inlet racks where appropriate , The distribution station of the intermediate interconnection rack and the outlet rack.

[0038] The set of busbars includes three busbars for...

Abstract

The invention discloses a connecting device for electrically connecting the adjacent middle-high voltage frames, comprising a lining sleeve (20) composed with the electrically insulating and flexibly deforming materials limiting the vertical axial line (X'); a first and second connecting clamper (24) provided in the lining sleeve (20) along the vertical axial line (X'); the first and second connecting clampers (24) are distributed as the contact component (12) connecting the first frame (4) and the contact component (12') connecting the first frame (4'); and a first and second tubular springs (26) respectively circling the first and second clampers to apply the axial force.

Description

technical field [0001] The present invention relates to an electrical connection for the electrical connection between two bays of medium and high voltage, and to a distribution station for distributing electric power at medium and high voltage, the substation comprising at least one such connection At least two racks where the unit is connected together. Background technique [0002] It is known to construct medium and high voltage substations consisting of a number of modules called metal clad racks and filled with materials such as sulfur hexafluoride (SF 6 ) Dielectric gas. The distribution substation includes an inlet rack, an outlet rack, and an interconnect rack interposed between the inlet rack and the outlet rack. Means for connecting together adjacent racks, in particular busbar sets of each rack, are provided between adjacent racks. [0003] Connection means of the above-mentioned type are disclosed, for example, in documents EP 0 891 013 and EP 520 933 . Thes...
