Abstract

Изобретение относится к области электромашиностроения, а именно к газовому охлаждению электрических машин с самонапорным ротором. Технический результат - снижение механических потерь, обеспечение равномерного распределения охлаждающего газа по каналам ротора и эффективное охлаждение обмотки ротора. Электрическая машина содержит статор (1), ротор (4), установленный в статоре с зазором (3). В обмотке ротора имеются вентиляционные радиальные каналы (5), которые соединяются с подпазовыми каналами (6) и зазором (3). Вращающийся направляющий аппарат (11) размещен в осевом канале (7), который отделен от системы охлаждения статора цилиндрическим элементом (9). Осевой канал сообщается с подпазовыми каналами и подводящим каналом (12), который образован радиальными стенками (13) и (14). В подводящем канале установлен неподвижный направляющий аппарат (15), который обеспечивает предварительное закручивание потока охлаждающего газа в направлении вращения ротора.The invention relates to the field of electrical engineering, namely to gas cooling of electrical machines with self-pressure rotor. EFFECT: reduction of mechanical losses, ensuring uniform distribution of cooling gas through the rotor channels and effective cooling of the rotor winding. The electric machine contains a stator (1), a rotor (4) installed in the stator with a gap (3). In the rotor winding there are ventilation radial channels (5), which are connected to the sub-channel channels (6) and the gap (3). Rotating guide apparatus (11) is placed in the axial channel (7), which is separated from the stator cooling system by a cylindrical element (9). The axial channel communicates with the podpazovy channels and the inlet channel (12), which is formed by radial walls (13) and (14). A stationary guide vane (15) is installed in the supply channel, which ensures the precursor of the cooling gas flow in the direction of rotation of the rotor.
