Abstract

La présente invention concerne, aux fins de prévention et d'utilisation de la foudre, un dispositif d'attraction de la foudre (1) destiné à empêcher la foudre de tomber, un système de prévention contre la foudre (9), un générateur d'énergie éolienne (301), un système de production d'énergie éolienne, un dispositif de chargement (201, 201a) utilisant le courant extrêmement puissant de la foudre, ainsi qu'un système de chargement associé (210). Le dispositif d'attraction de la foudre comprend des parois extérieures chargeables (3a, 3b) et des dispositifs à décharge par effet couronne (4a, 4b) destinés à charger les parois extérieures (3a, 3b). Le dispositif de chargement (201) comprend un dispositif d'attraction de la foudre (202) destiné à attirer la foudre sur lui, une ligne de transmission (205) et des unités de chargement (206, 225). Le générateur d'énergie éolienne (301) comprend une partie base (307) disposée dans l'espace situé entre la base d'un pylône (305) et le sol (A) et constituée d'un matériau isolant, et un câble électrique (318) destiné à acheminer de l'électricité vers l'extérieur à partir d'un générateur (314) comprend un contact de connexion côté pylône (323) et un contact de connexion côté extérieur (325) servant de commutateurs entre un état conducteur et un état non conducteur.
