▎ 摘　　要

NOVELTY - Arc contact for switch comprises a fixed conductive segment, wear-resistant contact section and arc strike section, fixed conductive section is used to fix arc contacts for switches. The wear-resistant contact section is located between the fixed conductive section and the arc striking section. Wear-resistant contact segments is used for electrically conductive contact with matching arc contacts. The conductivity of the fixed conductive segment is greater than that of the wear-resistant contact segment. The wear-resistant contact section and arc striking section are made of copper-tungsten alloy material. The content of tungsten in the wear-resistant contact section is less than the mass percentage of tungsten in the arc striking section. The wear-resistant contact segment further includes 0.01-0.02 wt.% graphene. USE - Used as arc contact for switch. ADVANTAGE - The arc contact: improves ablation resistance of the arc striking section and the conductive performance of the wear-resistant contact, wear-resisting property of wear-resistant contact; meets the requirement of arc contact resistance ablation and wear resistance and conductivity; prolongs service life; and improves stability of the safety breaker operation by using the self-lubricating property of the graphite. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a breaker. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the arc contact for switch.
