AI Technical Summary
Technical Problem
Under low-temperature conditions, existing wind turbine generator sets are prone to mechanical component jamming in variable pitch and variable wind speed systems, increasing maintenance costs.
Method used
The system employs an electric heating wire heating system within the shroud, and a fan draws heated air into the mounting shroud to ensure that components such as the reducer and blade bearings maintain appropriate temperatures under low-temperature conditions, thereby reducing wear.
Benefits of technology
It effectively avoids wear and tear on mechanical parts under low-temperature conditions, reducing maintenance costs.

Abstract
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.
