Abstract
An electrode assembly for a vacuum interrupter is disclosed having a coil structure that produces an axial magnetic field during operation of the assembly. The electrode coil includes at least one arcuate arm having a radial cross section which provides more material adjacent to a base of the coil than adjacent to a contact plate of the assembly. In a preferred embodiment, the cross sectional area of the arcuate arm has a trapezoidal shape. The electrode assembly provides improved heat transfer during operation of the vacuum interrupter while maintaining a sufficient axial magnetic field. As a result, the electrode assembly may be operated at higher continuous currents than conventional designs.
