Abstract

Disconnector for switchgear, having a first contact position, in which a contact is between main and first terminals, and a second contact position, in which a contact is between the main and second terminal. The disconnector includes a connector body moveable in a first direction between the first and second positions and having an end extendable in a direction substantially perpendicular to the first direction for providing a contact force between the end and the first, second or main terminals, a first operating mechanism arranged to move the body between the first and second positions, and a second operating mechanism arranged to extend the end when the disconnector is in either the first or second contact positions, in which the end includes a conical inside surface and the second operating mechanism includes a first shaft having a first conically shaped end positioned inside the conical inside surface.

Dependent claims

Disconnector for switchgear, having a first contact position, in which an electrical contact is provided between a main terminal and a first terminal, and a second contact position, in which an electrical contact is provided between the main terminal and a second terminal, the disconnector comprising:

a connector body having a longitudinal axis, the connector body being moveable in a first direction between the first and second contact positions and provided with an end portion which is extendable radially outwardly with respect to the longitudinal axis in a direction substantially perpendicular to the first direction for providing a contact force between the end portion and the first, second or main terminals,
a first operating mechanism which is arranged to move the connector body between the first and second contact positions, and
a second operating mechanism which is arranged to radially outwardly extend the end portion of the connector body when the disconnector is in either the first or second contact position,
in which the end portion of the connector body is provided with a conical inside surface and the second operating mechanism comprises a first shaft provided with a first conically shaped end body positioned inside the conical inside surface of the end portion of the connector body.
