摘要： A lightning current transfer system for a wind turbine generator is provided, the wind turbine generator comprising a rotor including a hub, a blade bearing, a blade, and a spinner, and a nacelle, the blade being rotatable relative to the hub and the hub being rotatable relative to the nacelle. In order to effectively protect the wind turbine generator from damage caused by lightning, to increase flexibility of use, simplicity, rigidness, operational safety and durability of such a lightning current transfer system, especially for use in a wind turbine generator brought into offshore operation, the lightning current transfer system comprises a first electrical contact arrangement including first and second complementary contact members, the first contact member being supported at the blade and being in electrical connection with a blade conductor arrangement arranged on the blade, the second contact member being supported at the hub, the spinner or the blade bearing, wherein the first and the second contact members are arranged to be electrically connectable to each other, conducting means connected to the first electrical contact arrangement, a second electrical contact arrangement connected to the conducting means and including third and fourth complementary contact members, the third contact member being supported at the hub, the spinner or the blade bearing, the fourth contact member being supported at the nacelle, wherein the third and the fourth contact members are arranged to be electrically connectable to each other, the lightning current transfer system providing a current path for a lightning current from the blade to the nacelle, the current path including the first electric contact arrangement, the conducting means and the second electric contact arrangement, the first contact member being arranged in a predetermined distance from a blade root of the blade, said blade root being mounted to the hub by means of the blade bearing, and wherein the first contact member is formed as a discharge ring being connected to the blade conductor arrangement, the blade conductor arrangement being formed by a metal foil or a metal mesh extending over at least a part of a longitudinal extension of the blade, wherein the lightning current transfer system is disposed inside of the spinner and/or inside of the nacelle, and wherein the conducting means is mounted stationarily at a mounting member, the mounting member being supported at the spinner, the hub or the blade bearing or being formed by the spinner, the hub or the blade bearing. Moreover, a wind turbine generator comprising a lightning current transfer system of the aforementioned kind is provided.
