Abstract

The invention relates to a stator for a turbogenerator provided with the affective gas cooling of the coil and teeth thereof. A core (2) with a winding (3) is arranged in the stator body (1). The core consists of the packages of steel plates (5) and ventilating channels (7). Said ventilating channels are formed by ventilating spreaders (8) and are closed on the side of the bore of the stator core. A high-pressure chamber (9) located in the space between the body and the core is provided with air ducts (10) which are disposed on the external surface of the core along the total length thereof in each second intertooth interval. Said air ducts are connected to the ventilating channels on one side and to a low-pressure chamber, which is situated in the space of the face parts of the stator winding, on the other side. The ventilating spreaders are placed in the tooth area in such a way that the cooling gas flow is shifted in an axial direction towards the adjacent ventilating channel via through holes (6). Said ventilating spreaders are arranged in a heelpiece area in such a way that the cooling gas flow in the even ventilating channels passes from the high-pressure chamber to the tooth area and in the uneven ventilating channels said flow passes from the tooth area to the air ducts.
