Abstract
A first contact 10 has an end portion 16 which engages a second contact 17, 18 in a contacts closed position of the switchgear and which moves transversely across a pole face of a field coil 23 and inwardly of an axis 24 of the latter during movement of the contacts to an open position. The field coil 23 is electrically connected in series with an arcing electrode 22, and to which the second contact 17,18 is also connected. Upon movement of the contacts from their closed position to their open position, an arc is drawn between the end portion 16 of the first contact and a portion 18 of the second contact. Further movement of the contacts towards their open position causes the arc to transfer its root from the second contact portion 18 to the arcing electrode 22 so that an arcing current then flows through the field coil 23 to generate a magnetic field which causes the arc to rotate and become extinguished. Extinction of the arc is assisted by an electrically insulating fluid surrounding the switchgear. A principal arcing zone is defined by rotation of the arc, and the arc is disposed in this zone when it transfers its root from the second contact to the arcing electrode 22 so that it can rotate immediately under the influence of the magnetic field.
