Vim li cas cov hnub qub txuas feem ntau siv rau cov stators ntawm cov motors high-voltage?

Rau cov cav uas muaj hluav taws xob tsawg, lawv raug faib ua ntu raws li lub zog. Piv txwv li, hauv cov cav yooj yim, muaj ciam teb 3kW; cov uas tsis tshaj 3kW txuas nrog lub hnub qub, thaum cov seem txuas nrogdeltaRau cov cav hloov pauv zaus, ciam teb yog teem rau ntawm 45kW; cov uas tsis tshaj 45kW txuas nrog rau hauvlub hnub qub, thiab tus so txuas nrog hauv delta. Raws li rau kev tsa thiabcov motors metallurgical, kev sib txuas hnub qub yog ntau duafeem ntau, thiab cov motors loj loj kuj tseem yuav siv taukev sib txuas delta.

Cov cav fais fab siabfeem ntau txuas nrog lub hnub qub teeb tsa kom tiv thaiv cov windings ntawm lub cev muaj zog los ntawm kev raug rau cov hluav taws xob siab.Hauv kev sib txuas ntawm lub hnub qub, qhov tam sim no ntawm kab yog sib npaug rau qhov tam sim no ntawm theem, thiab qhov hluav taws xob ntawm kab yog qhov square root ntawm 3 zaug ntawm qhov hluav taws xob ntawm theem (hauv kev sib txuas delta, qhov hluav taws xob ntawm kab yog sib npaug rau qhov hluav taws xob ntawm theem, thaum qhov tam sim no ntawm kab yog qhov square root ntawm 3 zaug ntawm qhov tam sim no ntawm theem). Yog li ntawd, qhov hluav taws xob uas cov windings ntawm lub cev muaj zog dais yog qhov tsawg heev. Hauv cov motors uas muaj hluav taws xob ntau, qhov tam sim no feem ntau me me, thiab qhov yuav tsum tau ua kom sov rau lub cev muaj zog yog siab. Yog li, qhov rwb thaiv tsev ntawm cov motors uas txuas nrog hauv lub hnub qub teeb tsa yooj yim dua rau kev tswj hwm thiab pheej yig dua.
