摘要： An electrical contact is for a vacuum switching apparatus. The vacuum switching apparatus includes a second electrical contact. The electrical contact includes a body having a center point and a periphery, the body including a plurality of arcing surfaces structured to face in a first direction toward the second electrical contact and structured to move into and out of engagement with the second electrical contact, and a plurality of arc spinning portions each defining a slot extending inwardly from the periphery generally toward the center point, the plurality of arc spinning portions generally separating the plurality of arcing surfaces from one another. At least one arc spinning portion narrows from a corresponding pair of adjacent arcing surfaces of the body to an interior thereof in a second direction opposite the first direction.

摘要： A contact of a vacuum interrupter comprises a contact body portion formed in the shape of a circular plate, having a contact surface in a flat shape on one surface thereof, and provided with a plurality of cut portions formed in a spiral shape from a center of the contact surface toward an outer side in a radial direction, and an inclination area formed between the contact surface and an outer circumferential surface of the contact body portion. The contact of the vacuum interrupter is characterized in that the inclination area is provided with multi-stage inclined portions each forming a multi-stage inclination along the outer side of the contact body portion in the radial direction.

摘要： A contact assembly for a vacuum switching apparatus includes a contact member and a reinforcing member adapted to structurally reinforce the contact member. The contact member includes first and second opposing sides, and a contact thickness. The reinforcing member has a reinforcement thickness, which is less than the contact thickness. The contact member is made from a first material having a first coefficient of thermal expansion, and the reinforcing member is made from a second different material having a second coefficient of thermal expansion. The first coefficient of thermal expansion is substantially the same as the second coefficient of thermal expansion.

摘要： The method involves sealing a vacuum switching chamber close to a contact piece according to a chill casting manufacturing process, while a substance is melted in a crucible and is cast into a die (1). Bars (4) are attached in the die, where the die lies horizontally during casting under a vacuum atmosphere in a kiln and resulting composite material includes a material combination of copper and chromium. The die is separated and is opened for disconnecting the contact piece. An independent claim is also included for a contact piece for a vacuum switching chamber.
