Description
Насто щее изобретение относитс к системам охлаждени ротора электрической синхронной машины с вно вырал енными полюсами, имеющим дл прохода охлаждающего газа каналы, сделанные в проводниках катушек полюсов поперек витков этих катушек, и зазоры между катушками и сердечниками полюсов.The present invention relates to rotor cooling systems of an electric synchronous machine with explicit poles, having channels for the passage of cooling gas, made in the conductors of the coils across the coils of the coils, and the gaps between the coils and the cores of the poles.
Предлагаема система отличаетс от известных тем, что в сердечниках полюсов также сделаны каналы дл прохода охлаждающего газа совпадающие с каналами, устроенными в остове ротора, и перекрытые на его периферии.The proposed system differs from the known ones in that in the cores of the poles there are also made channels for the passage of cooling gas that coincide with the channels arranged in the core of the rotor and blocked at its periphery.
Такое выполнение системы позвол ет повысить интенсивность охлаждени ротора.Such an embodiment of the system makes it possible to increase the intensity of cooling of the rotor.
На чертеже изображена схема предлагаемой системы.The drawing shows a diagram of the proposed system.
Дл охлаждени ротора синхронной машины в проводниках катушек полюсов предусмотрены каналы 2 дл прохода охлаждающего газа, которые выполн ютс следующим образом. Катушка изготовл етс из двухслойной меди, причем в одном из слоев или в каждом слое делаютс углублени , образующие при сопр жении со вторым слоем каналы, расположенные поперек витка. В сердечнике 3 полюса выполнены каналы 4, совпадающие с каналами в остове ротора. Каналы в сердечнике перекрыты по периферии остова ротора.In order to cool the rotor of the synchronous machine, the conductors of the coils of the poles provide channels 2 for the passage of cooling gas, which are performed as follows. The coil is made of two-layer copper, and in one of the layers or in each layer there are made recesses, which, when mated with the second layer, form channels located across the coil. In the core of the 3 pole channels 4, coinciding with the channels in the core of the rotor. The channels in the core are closed at the periphery of the rotor core.
Между катушкой обмотки полюса и сердечником выполнен зазор 5, по которому воздух, нагнетаемый при вращении ротора, через каналы 4 распростран етс по всей внутренней поверхности катушки и выходит через каналы 2 в витках катушки. Зазор между катушкой и сердечником устанавливаетс с помошью распорок 6. Изол ци 7 сердечника состоит из отдельных элементов в пределах каждого пакета сердечника полюса. Между этими элементами образуютс щели, по которым воздух проходит из каналов 4 в зазор 5.Between the coil of the pole winding and the core there is a gap 5, through which the air forced by the rotation of the rotor, through the channels 4, spreads over the entire inner surface of the coil and exits through the channels 2 in the turns of the coil. The gap between the coil and the core is established by means of the spacers 6. The core insulation 7 consists of separate elements within each pole core package. Between these elements, slots are formed through which air passes from channels 4 to gap 5.
