CONTACT FOR HIGH-VOLTAGE VACUUM ARC-QUENCHING CHAMBER Russian patent published in 2016 - IPC H01H33/664 

FIELD: electricity.

SUBSTANCE: contact for high-voltage vacuum arc-quenching chamber comprises a conductive connection element, an outer circular contact and inner contact placed inside a circle of outer contact and not contacting with it, as well as conductive connection element. Inner and outer contacts are coaxial, at that contact surface of inner contact is in the same plane as contact surface of outer contact. The outer contact is fixed to the conductive connection element. The axial magnet field facility is closed from outside with the conductive connection element in order to generate an axial magnet field. The axial magnet field facility is fixed rigidly to the conductive connection element. The inner contact is fixed to the conductive connection element, at that axial magnet field facility is closed from outside by the conductive connection element in order to generate an axial magnet field.

EFFECT: fast quenching of electric arc in high-voltage conditions thus leading to reduced heating of vacuum arc-quenching chamber.
