Ua ntej, cov khoom siv rwb thaiv tsev ua rau muaj qhov sib txawv, cov cav hluav taws xob qis, cov kauj feem ntau siv cov hlau enamelled lossis lwm yam rwb thaiv tsev yooj yim, xws li daim ntawv sib xyaw, cov cav hluav taws xob siab feem ntau siv cov qauv rwb thaiv tsev ntau txheej, xws li daim kab xev mica hmoov, cov qauv nyuaj dua, qib siab dua ntawm kev tiv thaiv siab.
Qhov thib ob, qhov sib txawv ntawm cov qauv txias, cov cav qis-voltage feem ntau siv cov kiv cua coaxial txias ncaj qha, cov cav siab-voltage feem ntau nrog lub radiator ywj pheej, feem ntau yog ob hom kiv cua, ib txheej ntawm cov kiv cua ncig sab hauv, ib txheej ntawm cov kiv cua ncig sab nraud, ob txheej ntawm cov kiv cua khiav tib lub sijhawm, hauv lub radiator cua sov pauv yuav raug tso tawm sab nraud lub cev muaj zog cua sov.
Qhov thib peb, cov qauv ntawm cov kabmob sib txawv, cov cav hluav taws xob qis feem ntau muaj cov kabmob ntawm pem hauv ntej thiab nram qab, thaum cov cav hluav taws xob siab, vim yog lub nra hnyav, feem ntau muaj ob pawg ntawm cov kabmob ntawm qhov kawg axial, thiab tus lej ntawm cov kabmob ntawm qhov kawg tsis yog axial yog txiav txim siab raws li qhov xwm txheej thauj khoom, thiab tshwj xeeb tshaj yog cov cav loj yuav raug siv rau hauv cov kabmob swb.
(1) Lub cev muaj zog siab muaj peev xwm ua tau muaj zog heev, txog li ntau txhiab lossis txawm tias kaum txhiab kilowatts. Qhov no yog vim tias, hauv tib lub zog tso zis, lub cev muaj zog siab tam sim no tuaj yeem me dua li lub cev muaj zog qis (feem ntau yog inversely proportional rau lub zog), piv txwv li, 500kW, 4-ncej lub cev muaj zog ntsuas tam sim no, qhov ntsuas voltage ntawm 380V rau 900A lossis li ntawd, thaum qhov ntsuas voltage ntawm 10kV thaum tsuas yog li 30A. Yog li lub cev muaj zog siab winding tuaj yeem siv rau cov xov hlau me dua. Yog li ntawd, qhov poob tooj liab stator ntawm lub cev muaj zog siab kuj yuav tsawg dua li ntawm lub cev muaj zog qis. Rau cov cev muaj zog loj dua, kev siv hluav taws xob qis, tab sis vim yog qhov xav tau cov xov hlau tuab dua thiab xav tau thaj chaw loj ntawm stator groove, yog li ntawd lub stator core txoj kab uas hla los ua ntau lub cev muaj zog ntim kuj yuav loj heev.
(2) Rau cov cav loj dua, cov cav high-voltage siv rau hauv kev muab hluav taws xob thiab cov khoom siv faib hluav taws xob tsawg dua li kev nqis peev tag nrho hauv cov cav qis-voltage, thiab kev poob kab me me, tuaj yeem txuag tau qee qhov kev siv hluav taws xob. Tshwj xeeb tshaj yog 10kV high-voltage motors, tuaj yeem siv ncaj qha rau ntawm lub network fais fab mov (Tuam Tshoj lub zog hluav taws xob siab rau tus neeg siv feem ntau yog 10kV), yog li kev nqis peev hauv cov khoom siv fais fab (feem ntau yog transformers) yuav tsawg dua, kev siv yooj yim dua, qhov ua tsis tiav yuav tsawg dua.
