Description
РОНЫ каналы 8 соединены трубопроводами 10 с каналами охлаждени 11 хвостовиков 12, 13 вала. По концам вала размещены 5 стройства 14 сбора хладагента, выход щего из каналов 11. Через хвостовик вала 12 проходит трубопровод 15 подачи хладагента к обмотке возбуждени 4, а в хвостовике 13 размещены токовводы 16, соедин ющие обмотку возбуждени 4 с контактными кольцами 17. Оболочка криостата 5 крепитс к боковым фланцам 18 хвостовиков вала . С фланцем 18 через вкладыш 19 скреплены обмотки возбуждени 4. Крепление вкладыща 19 к флапцу 18 осуществлено посредством щтифтов 20, установленных в отверсти х 21, заваренных вакуумплотными щвами.RONES channels 8 are connected by pipelines 10 to cooling channels 11 of shaft shanks 12, 13. At the ends of the shaft, 5 refrigerant collection device 14 exiting channel 11 are placed. Through the shaft shaft 12 passes the refrigerant supply pipe 15 to the excitation winding 4, and in the shank 13 current leads 16 are located connecting the excitation winding 4 with contact rings 17. Cryostat casing 5 is attached to the side flanges 18 of the shaft shanks. The excitation windings 4 are fastened with the flange 18 through the liner 19. The liner 19 is fastened to the flapz 18 by means of latches 20 installed in the openings 21 welded by vacuum tight joints.
Охлаждение ротора электрической мащины осуществл етс хладагентом, поступающим по трубопроводу 15 к расположенной во внутреппей полости криостата сверхпровод щей обмотке возбуждени 4. От обмотки 4 хладагепт поступает через трубопроводы 9 в каналы охлаждени 8 электротермоэкрана 6, а затем через трубопроводы 10 подаетс в каналы охлаждени 11 хвостовиков вала, откуда поступает в устройства 14 сбора хладагента и направл етс в холодильную установку.The rotor of the electric masch is cooled by the refrigerant flowing through the conduit 15 to the superconducting field winding 4 located in the cryostat cavity of the cryostat 4. From the winding 4, the refrigerant flows through the conduits 9 into the cooling channels 8 of the electrothermal screen 6, and then through the pipelines 10 flows 11 into the cooling channels 11 of the tailings the shaft from where it enters the refrigerant collection devices 14 and is sent to the refrigeration unit.
Расположение токоввода 16 в хвостовике вала 13 со стороны противоположной трубонроводу 15 ввода хладагента исключает дополнительный подогрев поступающего хладагента. Така конструкци ротора позвол ет улучшить его охлаждение и может быть применена дл крупных криогенных электрических мащип.The location of the current lead 16 in the shank of the shaft 13 from the side opposite to the pipe line 15 of the refrigerant inlet eliminates additional heating of the incoming refrigerant. Such a rotor design allows for improved cooling and can be used for large cryogenic electrical installations.
