<p>The present invention relates to a structure for preventing lightning in an electric power transmission tower. The structure for preventing lightning in an electric power transmission tower includes an electric power transmission tower vertically installed on a ground; a ground plate laid underground under the electric power transmission tower; an insulation casing fixed to a top end of the electric power transmission tower and configured by an insulator; an insulation gas tank eccentrically inserted into the insulation casing; an insulation material eccentrically inserted between an inner peripheral surface of the insulation casing and an outer peripheral surface of the insulation gas tank; a lightning guide part disposed in a upward direction of the electric power transmission tower and including a bottom end formed through top ends of the insulation casing and the insulation gas tank inside the insulation gas tank; a ground guide part including a top end formed through bottom ends of the insulation casing and the insulation gas tank inside the insulation gas tank; and a connector to connect a bottom end of the lightning guide part to a top end of the ground guide part inside the insulation gas tank. A connection part between a bottom end of a lightning guide bar and a top end of a ground cable connected by the connector is disposed inside the insulation gas tank which is filled with SF6 having excellent insulation and arc properties. The insulation gas tank is configured to be insulated by the insulation material and the insulation casing so that the lightning guide bar and the ground cable may be clearly insulated from a lightning conductor into which lightning is introduced with respect to the electric power transmission tower. Accordingly, when the lightning is grounded through the lightning conductor, the lightning guide bar, and the ground cable, the light may be clearly prevent from being flown through the electric power transmission tower. As a result, walkers or workers around the electric power transmission tower may be protected from a lightning accident.</p> |
