FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering and may be used in wind-driven power plant. Annular generator of the wind-driven power plant includes stator, peripherical stator ring for placement of stator windings, rotating part which is installed so that it can rotate in relation to stator and lid of the stator connected to stator ring. Lid provides formation of discharge chamber with high or low pressure; it is designed to ensure air flow passing through and/or in stator and/or rotating part in order to cool annular generator. At that in the stator lid there is at least one air blower with opening designed for it. The air blower can be rotated by driving mechanism in order to open the air blower opening for the purpose of maintenance and/or man passage through it.
EFFECT: more effective cooling of annular generator.
