摘要

[PROBLEMS] To provide, in view of prevention and utilization of lightning, a lightning attracting device (1) for preventing lightning, a lightning prevention system (9), a wind power generator (301), a wind power generation system, a lightning charging device (201, 201a) utilizing the lightning current having a very large power, and a lightning charging system (210). [MEANS FOR SOLVING PROBLEMS] A lightning attracting device comprises chargeable outer walls (3a, 3b) and corona discharge devices (4a, 4b) for charging the outer walls (3a, 3b). A lightning charging device (201) comprises a lightning attracting device (202) for attracting lightning on itself, a transmission line (205), and charging units (206, 225). A wind power generator (301) comprises a base part (307) disposed in the whole space between the base of a tower (305) and the ground (A) and formed of an insulating material, and an electric cable (318) for supplying electric power to the outside from a generator (314) comprises a tower-side connection contact (323) and an outer-side connection contact (325) serving as change-over switches for switching between a conducting state and a nonconducting state.
