ABSTRACT:
An electrical arrester includes one or more pairs of electrodes disposed within quenching chambers which form current-limiting quenched spark gaps connected in series with an associated blow-out coil for magnetically influencing the arc in the quenching chambers. During the quenching operation, the blow-out coil is short-circuited and two different embodiments are disclosed for effecting this result. In one embodiment, the quenching chamber includes a short-circuiting electrode in the vicinity of that one of the electrodes of a pair which is conductively connected to one end of the blow-out coil and the other end of the latter is conductively connected to the short-circuiting electrode. In the other embodiment, the arrester includes a pair of auxiliary electrodes disposed within an auxiliary chamber and forming a by-pass spark gap connected in parallel with the blow-out coil. A short-circuiting electrode is also disposed in the auxiliary chamber in the vicinity of that one of the auxiliary electrodes that is connected to one end of the blow-out coil and the opposite end of the latter is conductively connected to the short-circuiting electrode.
