Electrical contact for high-voltage circuit breaker

摘要

A gas-insulated high-voltage circuit breaker (200) is provided for interrupting a current between a first breaker contact (132) and a second breaker contact (134) in an arc interruption current path other than the rated current path. For that purpose an elongated contact rod (20) is provided that comprises at least one lateral protrusion (30) extending in a radial direction away from a switching axis (25) and being arranged in between a first contact portion (55) and a cylindrical portion (22) of the contact rod (20) such that the first contact portion (55) is rigidly and electrically and mechanically rigidly connected to the cylindrical portion (22) via the at least one lateral protrusion (30). The first contact portion (55) engages with a mating contact portion (90) of the first breaker contact (132) such that the elongated contact rod (20) is continuously electrically contacted to the first breaker contact (132).
