<p>A vacuum-type circuit interrupter is provided having an axial magnetic field provided therein through the use of currents transmitted to the surrounding shield structure, the latter being electrically connected by means of a field coil to one of the separable contacts. In one embodiment, the surrounding condensing shield is connected by an internal coil strap to one of the separable contacts. In another embodiment, the coil, providing the axial magnetic field, is disposed externally of the evacuated envelope, and is connected by a connection extending through the envelope to the condensing shield, which may be electrically isolated internally from the electrodes or contacts. In another embodiment, the axial magnetic field-producing coil is disposed externally of the envelope, but has a connection to an end plate, which, additionally, is electrically connected to the internal condensing shield.</p> |
