Abstract

The utility model relates to a novel line arrester for an electric power line. The novel line arrester comprises an arcing ring and a support body. The arcing ring is electrically connected with a lighting-induction arc extinguishing band. The arcing ring and the lighting-induction arc extinguishing band are fixed on the support body. The one or multiple lighting-induction arc extinguishing bands are all connected with amour clamps at two ends of the support insulating pipe, for the purpose of rapid electric arc extinguishing or shunt arc extinguishing. The arcing ring is located at the high-voltage side, and an appropriate air gap is maintained between the arcing ring and a power line wire, so as to induce the lightning into the lighting-induction arc extinguishing band. The great energy of the lightning is consumed within gaps between segmented electrodes by means of the lighting-induction arc extinguishing band, and segmented arc extinguishing in a one-by-one manner is adopted, thereby achieving the aim of lightning protection.
