ABSTRACT:
A device for protection against voltage surges comprises a stationary electrode and a movable electrode arranged facing an arc extinguishing chamber. The movable electrode is driven by a mechanisms, by an electromechanical actuator and/or by an electromagnetic circuit. At rest, the movable electrode is situated at a distance from the stationary electrode. When a voltage surge occurs between the electrodes, an arc arises and extends in the chamber in which it is extinguished. If the arc continues, in particular in the case of a follow current of high energy, the movable electrode is driven to a disconnected position moving away from the stationary electrode, which has the effect of lengthening the arc even more in the chamber to facilitate its extinction and perform disconnection of the circuit. A pair of contacts may be associated in series to the electrodes, one of the contacts being stationary and the other being fixedly secured to the movable electrode. A spark gap can also be associated to the electrodes.
