Creeping discharge lightning protection device |
摘要 |
A lightening countermeasure for overhead power lines guards against breaking of wire and momentary service interruption without using any ZnO device. A lightening arrester body for an overhead power line includes a double-folded insulated wire which is insulated to a same extent as that of a power cable. A conductor-exposed side of the lightening arrester body is connected to an insulator-earthing side, and an insulating cover side is disposed on a discharge electrode side provided to an overhead power line. A needle electrode of the discharge electrode penetrates the insulating cover of the overhead power line. Where the overhead power line is bare wire, the conductor-exposed side of the arrester body is connected to the insulator-earthing side, and the insulator cover side is connected to the overhead power line.
