Kuj tsis paub meej ceev txoj cai kho
Lub nrawm ntawm lub cev muaj zog yog hloov los ntawm kev hloov qhov kev sib txuas ntawm cov qauv windings, uas yog hais, qhov kev sib hloov ceev ntawm lub cev muaj zog yog hloov los ntawm kev hloov logarithm ntawm lub sib nqus ntawm cov sib nqus ntawm tig lub sib nqus ntawm lub cev muaj zog.
Ob-lub cev muaj zog (kiv cua), feem ntau yog qhov nrawm qis, qee zaum tus kiv cua ntawm kev kub ceev, feem ntau dhau los ntawm kev tswj cov kab sab nraud hauv qab no tom qab kom hloov qhov kev sib hloov winding ntawm lub cev muaj zog kom ua tiav.
1. Muaj ob qho kev sib tw ua ke nrog cov sib txawv ntawm cov logarithms sib txawv ntawm cov kab hluav taws xob, thiab cov cav logarithms tuaj yeem hloov tau los ntawm kev hloov cov qauv sib txuas ntawm lub cev muaj zog stator windings los ntawm kev hloov ntawm cov kev tswj sab nraud;
2. Ob txoj hlua hlau tsis sib haum nrog logarithms sib txawv ntawm cov ncej yog ntim rau hauv cov stator slot;
3. Muaj ob txoj hlua cua tsis sib luag nrog cov logarithms sib txawv ntawm cov ncej txuas rau hauv cov stator slot, thiab txhua qhov cua ntsaws tuaj yeem muaj qhov sib txuas sib txawv.

Qhov ob-lub cev muaj zog yog los ntawm lub asynchronous lub cev muaj zog ncej-hloov cov kev cai ceev, uas yog hloov cov ncej ntau ntawm stator tig magnetic teb los ntawm kev hloov txoj hauv kev txuas ntawm stator windings, thiaj li hloov qhov ceev ntawm lub cev muaj zog.
Raws li cov qauv; N = 60f / p qhia tau hais tias synchronous ceev ntawm lub zog tsav asynchronous yog qhov sib npaug tsis sib luag rau cov logarithm ntawm cov hlau nplaum sib nqus. Yog tias qhov logarithm ntawm cov hlau nplaum sib nqus yog ob npaug, ceev ceev synchronous n txo mus rau ib nrab ntawm qhov kev nrawm thawj, thiab tus ceev ntsuas n ntawm lub cev tseem yuav txo los ntawm kwv yees li ib nrab. Yog li no, hloov txoj kev logarithm ntawm cov sib nqus sib nqus tuaj yeem ua tiav lub hom phiaj ntawm kev hloov ceev ntawm lub cev muaj zog. Cov txheej txheem kev nrawm no yog ua kom tiav, tsis yog kev nrawm nrawm txoj cai, thiab tsuas yog tsim rau cov vais-tawb lub cev muaj zog.
Daim duab no qhia txog cov kev sib tw ib qho tib si ib qho kev sib nqus ntawm lub cev muaj zog, qhov nrawm sib npaug yog sib npaug ntawm cov sib nqus sib nqus ntau qhov sib piv, xws li 2 tus ncej / 4 tus ncej, 4 theem / 8 ncej, los ntawm stator winding raws kev sib txuas rau YY kev txuas. txoj kev, tus naj npawb ntawm cov hlau nplaum sib tsoo los ntawm 2p = 2 txog 2p = 1.

Tus pabcuam ntu sijhawm qhib kev sib cuag ntawm KM2 raug txiav tawm kom tiv thaiv KM1 kev ua tsis tiav.
4. FR1 thiab FR2 yog tshaj kev tiv thaiv cov ntsiab lus rau lub cev ntaj ntsug ua haujlwm thiab YY lag luam feem.
5, tswj kev sib txuas ntawm SB2 ib txwm qhib kev sib cuag thiab KM1 coil hauv series, ib txwm kaw kev sib cuag nrog KM2 SB2 kauj hauv series, tib lub khawm SB3 ib txwm kaw kev sib cuag ntawm thiab KM1 coil series, SB3 nquag qhib rau KM2 kauj hauv series, qhov kev tswj hwm no yog khawm ntawm txoj kev sib tshuam, kom ntseeg tau tias qhov qeeb thiab YY ob txoj kev sib txuas yuav tsis tshwm sim nyob rau tib lub sijhawm, tib lub sijhawm KM2 ntu pab cuam ib txwm kaw kev nkag mus rau KM1 coil Circuit, ntu kev sib txuas ib txwm kaw KM1 nkag KM2 coil Circuit Court, kuj tsim lub interlock tswj.
Cov xwm txheej kev lag luam
Ob lub tshuab roj nrawm siv feem ntau hauv cov thee thee, roj av thiab cov nkev, kev lag luam roj av thiab tshuaj lom neeg. Tsis tas li ntawd, nws yog dav siv hauv textile, metallurgy, nroog roj av, tsheb thauj mus los, nplej thiab roj ua, ntawv ua, tshuaj thiab lwm yam. Raws li cov cuab yeej hluav taws xob loj, lub tshuab muaj ob-lub tshuab hluav taws xob feem ntau yog siv los tsav cov twj, kiv cua, compressors thiab lwm yam kev xa cov tshuab.
Nrog txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tsim khoom, cov chaw uas muaj kev pheej hmoo ntawm kev tawg yog nce ntxiv. Piv txwv, kev tsim cov roj siv tau los siv cov txheej txheem tso tawm tsoos, tom qab xyoo 1970, Tuam Tshoj pib qhia cov txheej txheem txawv teb chaws tam sim no, tab sis cov txheej txheem no siv cov kuab tshuaj uas muaj cov tshuaj ethane, ethane yog cov khoom tawg thiab tawg; Raws li qhov tshwm sim, chav ua yeeb yam dhau los ua qhov chaw muaj kev phom sij, xav tau siv ob lub cav nrawm thiab lwm yam khoom siv hluav taws xob tawg. Piv txwv li, nyob rau xyoo tas los no, Tuam Tshoj txoj kev loj hlob ntawm txoj kev loj yog muaj ntau nrawm, muaj ntau cov roj tsheb roj tshwm sim, kuj muab kev ua lag luam tshiab rau cov tsav ob-lub cav.
