DEVICE FOR PROTECTION AGAINST LIGHTNING WITH SURFACE DISCHARGE

摘要

Low-cost protection measures against wire breaks and instantaneous power outages are proposed without using any device containing ZnO to reduce the cost of lightning protection measures for overhead power lines. The housing (14) of the lightning conductor for overhead lines made of insulated wire is formed from a double insulated wire that has the same insulation as the power cable insulation. The side (15) of the conductor that is exposed to, the lightning discharge housing (14) is connected to the insulator ground side (13), and the insulating coating side (16) is located on the side of the discharge electrode (4) provided on the overhead line (1). In the insulating coating of the air line (1) on the side (16) of the insulating coating, advance penetration is called in advance by means of the needle electrode of the discharge electrode (4). Thus, a lightning conductor with a surface discharge is created. If the overhead line is an uninsulated wire, the exposed side of the conductor is connected to the ground side of the insulator and the side of the insulation coating is placed on the overhead line. The international application was published along with an international search report.
