Technical Field

The utility model relates to an improve horizontal novel lightning protection device of distribution lines lightning protection.

Background

Electric power is an energy source using electric energy as power. In the 70 s of the 19 th century, the invention and application of electric power opened up the second industrialized climax. The lightning protection device is one of three scientific and technological revolution which occur in the world since 18 th century of human history, a power transmission and distribution line is the basis of a power system and plays an important role in normal operation of the power system, the biggest threat of the power transmission and distribution line is lightning, the lightning is a natural discharge phenomenon, the lightning is huge destructive, particularly in summer, the lightning occupies the first place of line fault tripping, the lightning is a natural phenomenon of atmospheric activity and is uncontrollable so far, according to practical data statistics, the amplitude of lightning overvoltage can reach about 400kV, the amplitude of lightning current can reach about 100kA, and the high amplitude far exceeds the lightning resistance level of an overhead insulated line in a power distribution system of 35kV or below, so that the lightning protection device is required.
