Wind energy installation with a heating device

摘要: The invention relates to a wind energy installation having tower (10), pod which is arranged thereon and comprises rotor (12) generator (14) driven thereby, converter (15) for outputting electrical control device (16), wherein the connected network, temperature sensor heating are provided (16). According invention, an additional preheating module (4) provided, thermal switch (34, 36), monitors of at least one component operated on reaching threshold, monitoring unit (40) output (45), interacts with such that operates (23, 33) until (34) trips, (45) then transmits enable signal (50) in order start up installation. results temperature-critical components being preheated operating before starting up. startup only after phase. use UPS (18) makes it possible ensure all supplied voltage same time. This considerably improves operational reliability very low ambient temperatures, particular Arctic climates.
