According to the present invention, a lightning protecting apparatus for distributing lighting current comprises: a lightning rod (40) installed in a cable-stayed bridge; a ground body (80) for facilitating an electrical connection between the lightning rod and the earth; a down conductor (50) for connecting the lightning rod and the ground body; a support cable (30) for connecting a tower of the cable-stayed bridge and an upper plate of the bridge; a lightning inducing line (60) for protection on the support cable which is supported on the uppermost support cable among the multiple support cables by one or more insulating supports (90) and is connected in a lower part of the lightning rod (40) and the down conductor (50); and a conductor (70) for distributing current established in the support cable connected to the down conductor (50) and the ground body (80) in both end parts of the support cable, thereby minimizing current that flows in the support cable, especially, in an assembly of a steel wire forming the support cable, so as to secure stability of the cable-stayed bridge. |
