1 results about "Variable speed wind turbine" patented technology

The utility model relates to the technical field of wind generating sets, in particular to a variable-pitch variable-speed wind generating set. Comprising a flow guide cover, a mounting cover is mounted in the flow guide cover, an inner cavity is formed in the mounting cover, an electric heating wire is mounted in the inner cavity, a heat conduction plate is mounted at the position, close to the electric heating wire, of the mounting cover, a fan is mounted below the mounting cover, the outer side of the fan is connected with an air filter through a pipeline, and an adjusting motor is mounted in the mounting cover; the output end of the adjusting motor is connected with a first speed reducer, and the upper portion of the first speed reducer is connected with a second speed reducer through a transmission shaft. An electric heating wire heats a heat conduction plate and the interior of an inner cavity, air enters the inner cavity through a draught fan, the heated air enters a mounting cover to guarantee the environment temperature when a first speed reducer, a second speed reducer and a paddle bearing work, and in this way, the situation that the device works under the low-temperature condition can be avoided; therefore, abrasion between mechanical parts is reduced, and the maintenance cost of the device is reduced.
