Electrical contact arrangement and air insulated medium voltage circuit breaker including the electrical contact arrangement
Abstract:
An electrical contact arrangement for medium to high voltage applications includes a contact arm having a distal end section on which a circular shaped annulus arrangement having several axially and parallel directed contact fingers is arranged. The contact fingers are pressed on the contact arm via respective radially directed connection sections by a spring ring which is peripherally arranged around the contact fingers. The distal end section of the contact arm includes a first ring-shaped surface and an adjacent second ring-shaped surface, so that the connection section of each contact finger is pressed to at least both the first and second ring-shaped surfaces.
