Lub tshuab hluav taws xob hydro-generator muaj cov rotor, stator, thav duab, thrust bearing, guide bearing, cooler, nres thiab lwm yam khoom tseem ceeb (saib daim duab). Lub stator feem ntau yog ua los ntawm lub hauv paus, lub plawv hlau, thiab cov windings. Lub plawv stator yog ua los ntawm cov ntawv hlau silicon txias-rolled, uas tuaj yeem ua rau hauv ib qho kev sib xyaw thiab faib ua pawg raws li cov xwm txheej tsim khoom thiab kev thauj mus los. Txoj kev txias ntawm lub tshuab hluav taws xob dej turbine feem ntau siv cov cua txias kaw. Cov chav loj feem ntau siv dej ua cov khoom siv txias kom txias lub stator ncaj qha. Yog tias stator thiab rotor txias tib lub sijhawm, nws yog ob lub tshuab hluav taws xob dej turbine txias sab hauv.
Yuav kom nce lub peev xwm ntawm lub tshuab hluav taws xob hydro-generator thiab tsim kom loj heev, txhawm rau txhim kho nws txoj kev ntseeg siab thiab kev ruaj khov, ntau yam thev naus laus zis tshiab tau raug siv rau hauv cov qauv. Piv txwv li, txhawm rau daws qhov kev nthuav dav thermal ntawm stator, cov qauv stator floating, oblique support, thiab lwm yam tau siv, thiab lub rotor txais cov qauv disc. Txhawm rau daws qhov loosening ntawm stator coils, elastic wedges tau siv los underlay cov strips kom tiv thaiv cov rwb thaiv tsev ntawm cov hlau rods los ntawm kev hnav tawm. Txhim kho cov qauv cua kom txo qhov poob cua thiab xaus eddy tam sim no poob kom txhim kho qhov ua haujlwm ntawm lub tshuab.
Nrog rau kev txhim kho ntawm cov thev naus laus zis tsim cov twj tso kua dej turbine, qhov ceev thiab lub peev xwm ntawm cov cav generator kuj nce ntxiv, txhim kho mus rau qhov muaj peev xwm loj thiab ceev ceev. Hauv ntiaj teb, cov chaw tsim hluav taws xob cia khoom uas muaj cov cav generator muaj peev xwm loj, ceev ceev suav nrog Dinovic Pumped Storage Power Station (330,000 kVA, 500r/min) hauv tebchaws United Kingdom thiab lwm yam.
Siv ob lub tshuab hluav taws xob txias sab hauv uas siv dej txias, lub stator coil, rotor coil thiab stator core raug txias ncaj qha sab hauv nrog dej ionized, uas tuaj yeem ua rau lub tshuab hluav taws xob tsim khoom ntau dua. Lub tshuab hluav taws xob (425,000 kVA, 300r/min) ntawm La Kongshan Pumped Storage Power Station hauv Tebchaws Meskas kuj siv ob lub tshuab dej txias sab hauv.
Kev siv cov hlau nplaum sib nqus. Thaum lub peev xwm ntawm lub tshuab hluav taws xob nce ntxiv, qhov ceev kuj nce ntxiv, qhov hnyav thiab lub zog pib ntawm lub tshuab kuj nce ntxiv. Tom qab siv cov hlau nplaum sib nqus, qhov hnyav ntxiv nrog rau qhov sib nqus rub mus rau sab nraud ntawm lub ntiajteb txawj nqus, yog li txo qhov hnyav ntawm cov hlau nplaum, txo qhov poob ntawm qhov tsis kam ntawm axial, txo qhov kub ntawm cov hlau nplaum thiab txhim kho kev ua haujlwm ntawm lub tshuab, thiab qhov tsis kam pib lub sijhawm kuj txo qis. Lub tshuab hluav taws xob (335,000 kVA, 300r/min) ntawm Sanglangjing Pumped Storage Power Station hauv Kaus Lim Qab Teb siv cov hlau nplaum sib nqus.
