FIELD: electricity.
SUBSTANCE: arc-quenching system includes contacts and insulation case in the form of hollow tube with slots on internal surface positioned over gaps along the whole case length. Each slot features through orifices opposite to each other. System features longitudinal magnetic blowout device.
EFFECT: enhanced heat transfer from electric arc to environment, increased arc-quenching ability due to arc rotation between case slots and reduced exhaust gas effect on internal case surface.
