Abstract RU 2329579 C1

FIELD: electric engineering.

SUBSTANCE: commutation contact for vacuum arresters with radial or axial magnet field contains contact board and pot-shaped contact holder with coil for creation of magnet field, which is formed by azimuthal slots of pot-shaped contact holder wall. External diameter of pot slotted wall is less than the diameter of contact board installed on it. Between contact board and base of contact holder ring-shaped support body is inserted, which embraces contact holder in at least slotted area.
