NOVELTY - The utility model claims a vacuum arc extinguish chamber. the conductive loop is covered on the surface of the vacuum arc extinguish chamber with graphene. The utility model claims a vacuum arc extinguish chamber, the surface of each component of the conductive loop is covered with graphene, the graphene with good thermal conductivity, electrical conductivity and heat dissipation, reduce the cost of the conductive loop resistance, loop to transmit the heat generated by conductive and improves the thermal conductivity and heat dissipation of the conductive loop, effectively reduces the high rated current by the temperature rise in the vacuum arc extinguish chamber, which is suitable for all kinds of current level, reduce the temperature rise reaches 3 to 10 degrees C.
