Abstract:
An electrode assembly for a vacuum interrupter includes a contact plate, an electrode coil, an inner support, a lower support, and at least one support member. The electrode coil includes a base for attachment to a terminal post of the vacuum interrupter. The electrode coil also includes at least one arcuate arm between the base and the contact plate extending along a curved path in a plane substantially perpendicular to a direction of travel of the electrode assembly. Each arcuate arm includes an aperture that is positioned to align with a corresponding aperture of an adjacent arcuate arm or the base of the electrode coil. Each support member is partially positioned within aligned apertures to maintain a gap between the arcuate arms and the base. The support members and the lower support may be slotted to decrease the current flowing through the supports.
