Abstract:
    The utility model discloses an integrated lighting protection system for power transmission line. The system comprises vertical lighting arrester disposed on top of transmission tower and series-connected with impedor; two insulated support posts disposed on top of the transmission tower and on two sides of the lighting arrester; lighting ground wire disposed on top of the two insulated support posts, erected at a direction consistent with power transmission lines below tower top, and having discharger with upward tip; conductor wire for connecting the lighting ground wire and the lighting arrestor above the impedor; and magnetic induction choke components respectively fitted outside three power transmission lines below tower top for weakening high-frequency pulse current of lighting. The magnetic induction choke is hollow cylinder with magnetic matrix and used for accommodating insulated and sealed power transmission line in its cavity. The inventive lighting protection system can effectively weaken high-frequency pulse current component generated by lighting, and avoid power frequency short circuit of power transmission line.
