    摘要: A mold for encapsulating an electrical component. The mold includes an encapsulation chamber and an air inlet. The encapsulation chamber is defined by a housing, an open top, and a solid bottom. The housing includes a solid outer wall, a permeable inner wall, and an air chamber between the solid outer wall and the inner wall. The air inlet is configured to introduce a gas into the air chamber. The encapsulation chamber is sized and shaped to receive the electrical component while leaving a gap for the introduction of encapsulant around the electrical component. The encapsulant may be silicone rubber. To remove an encapsulated electrical component, pressurized air may be introduced through the air inlet into the air chamber, passing through the permeable inner wall, separating the outer surface of the encapsulant from the housing, and allowing the combination casting to be removed from the mold.

    摘要: 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.
