Abstract
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.

An actuating 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 movable electrode being movable between a closed position in which the two electrodes are in contact with each other and an open position in which the two electrodes are separated, the actuating system comprising:
- 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 a value of a current which passes through the coil reaches a predetermined threshold.
