The invention relates to a sectioning device for separating or connecting two parts of a three-phase electric circuit, intended to be positioned in an enclosure of a GIS substation. It comprises: three pairs of electrical contacts each having a moving contact and a stationary contact, the two contacts being able to assume an open position or a closed position of the electric circuit by relative translation of the contacts along a movement axis; for each pair of contacts, a telescoping device for guiding the moving contact along the movement axis, the guide device having a stationary part secured to the stationary contact and a moving part sliding relative to the stationary part and bearing the moving contact, the electrical contacts of the pair being electrically connected to each other via the guide device; a control device for controlling the moving part of each guide device to bring the guide device in extension into an open position and a closed position; for each guide device, movement transmission means connecting the control device and the moving part of each guide device. The control device is rotatably mounted relative to an axis of rotation, so that a rotation of the control device around the axis of rotation causes a translation of the moving contact of each pair of contacts along the movement axis via the movement transmission means. |
