A switching system for switching an electrical device, comprising: a vacuum interrupter including a fixed electrode, and a mobile electrode, the mobile electrode configured to move between a closed position and an open position. The switching system further comprising an elastic return means configured to apply a driving force to the mobile electrode, and a retaining member for retaining the elastic return means, the retaining member configured to move from a retention configuration, in which the elastic return means is immobilized, into a movement configuration, in which the elastic return means is released. The switching system is configured so that the mobile electrode moves from the closed position to the open position under the action of the elastic return means when the retaining member leaves its retention configuration.

Switching system of an electrical device

An electrical breaking contact, in particular a radial-magnetic-field electrical breaking contact, is provided for a medium-voltage vacuum interrupter, the contact including: a rod extending along a longitudinal axis, said rod being configured to be passed through by an electrical current, a contact body extending transversely to the longitudinal axis and including a first fastening surface, the contact body and the rod being coaxial, wherein the rod includes: a second fastening surface securely fastened to the first fastening surface, an abutment surface radially exterior to the first fastening surface (), the abutment surface being distant from the contact body along the longitudinal axis and turned toward the contact body.

Electrical breaking contact

A system for actuating a vacuum bottle of an electrical device, the vacuum bottle being connected in a circuit shunting a main circuit of a phase of the electrical device and comprising a movable electrode and a fixed electrode. The actuating system comprises a shunt contact which is connected to a movable contact of the main circuit during a movement of opening the electrical device, and an electromagnet whose coil is connected between the movable electrode and the shunt contact, and whose core is mechanically linked with the movable electrode, such that the core drives the movable electrode to the open position only when the value of the current which passes through the coil reaches a predetermined threshold.
