High voltage swivel with stacked ring-shaped conductor assemblies

Abstract

A high voltage swivel including an inner and an outer body, each body having at least a first and a second ring-shaped conductor element, the conductor elements including two spaced-apart end faces and a curved contact surface, the elements being mutually interconnected at opposing end faces via insulating members at axially spaced-apart positions, the inner and outer bodies being coaxial around a longitudinal axis, the contact surface of each inner conductor element being adjacent to and in electrical contact with an opposed contact surface of a corresponding outer conductor element, the inner and outer bodies being rotatable relative to one another around the longitudinal axis, each conductor element of the inner and outer body connected to a voltage line extending to an input terminal or an output terminal, the insulator members interconnecting the conductor elements situated at a mutual distance in the circumferential direction of the conductor element, the interconnected conductor elements of the inner and the outer body each being supported by a respective support member to form integral units such that the inner and outer bodies are adapted to be mutually decoupled or attached by relative displacement of the integral units in the direction of the longitudinal axis.
