Qee qhov zoo ntawm cov motors high-voltage yuav tsum tau lees paub thiab nyiam los ntawm kev ua lag luam.

Qhov kev thov rau10kV lub cev muaj zogyog loj dua li ntawd rau6kV lub cev muaj zog, thiab thaum xav txog zoo zoo, nws yeej tsis yog tsis muaj laj thawj. Nyob rau hauv xyoo tas los no, nrog rau kev siv cov cai txuag hluav taws xob thiab kev txhim kho ntawm cov hluav taws xob hauv tsev kom txo cov kab poob, cov lag luam kev lag luam thiab cov chaw ua haujlwm tsuas tau xaiv cov cav ntoo 10kV nruab nrab los hloov cov cav ntoo 6kV kom txo tau kev nqis peev faib khoom, ua rau muaj kev nce ntxiv ntawm qhov kev thov rau cov cav ntoo 10kV nruab nrab. Ib qho ntawm cov teeb meem kev siv tshuab ntawm cov cav ntoo no yog qhov rwb thaiv tsev ntawm qhovcov kauj statorVim yog cov hlau uas feem ntau nyias nyias, nws nyuaj rau siv cov ntaub nplaum mica uas qhwv tes lossis tshuab. Siv cov rwb thaiv tsev ntawm cov xov hlau uas qhwv zaj duab xis ua cov rwb thaiv tsev inter-turn ua rau tsis muaj zog tiv thaiv corona. Hauv kev ua tsis tiav ntawm lub cev muaj zog siab, qhov yuam kev inter-turn suav nrog ntau qhov loj, thiab kev ntseeg tau ntawm cov rwb thaiv tsev inter-turn tau nyiam ntau dua. Qee tus neeg siv txawm hais tias cov cav hluav taws xob siab yuav tsum siv mica raukev rwb thaiv tsev interturn.

Cov kev ntsuas uas tau ua nyob txawv teb chaws hauv qhov no yog kev siv mica ntau heevcov xov hlau qhwvHauv Suav teb, kev tshawb fawb txog kev rwb thaiv tsev inter-turn nrog cov ntaub nplaum mica hmoov tau ua tiav nyob rau hauv xyoo tas los no. Nrog kev pab los ntawmcov khoom siv rwb thaiv tsevcov chaw tsim khoom thiab cov chaw tsim khoom siv cav, qee qhovhluav taws xobCov chaw tsim khoom siv hlau tau ua tiav ntau hom xov hlau qhwv mica nrog cov qauv sib txawv. Tam sim no, ntau lub Hoobkas tsim khoom siv lub cev muaj zog tab tom thov thiab txhawb nqa lawv.

Feem ntau ntawm cov qhov tsis zoo thiab kev puas tsuaj ntawm cov cav uas tig yog los ntawm kev puas tsuaj ntawm cov rwb thaiv tsev winding. Ntawm lawv, cov rwb thaiv tsev inter-winding suav txog li 50%. Thiab thaum puas tsuaj lawm, qhov tshwm sim yuav loj heev. Kev luv luv ntawm cov rwb thaiv tsev inter-winding yog qhov tshwm sim los ntawm tus nqi hluav taws xob ntawm lub cev muaj zog inter-winding ntau dua qhov hluav taws xob ua haujlwm ntawm cov rwb thaiv tsev ntawm qee cov windings nyob rau hauv ntau yam xwm txheej overvoltage. Qee qhov yog los ntawm kev puas tsuaj ntawm cov coils thiab windings thaum lub sijhawm tsim khoom, thiab lwm qhov yog los ntawm kev tso tawm hauv zos sab hauv cov windings siab-voltage motor thiab corona corrosion ntawm cov windings siab-voltage. Cov kev puas tsuaj los ntawm cov yam no yog txhua yam ncaj qha lossis tsis ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov xov hlau winding siv hauv cov cav. Nrog rau kev hloov kho dua tshiab thiab hloov pauv ntawm cov cav tig thiab qhov xav tau ntau yam cav tshwj xeeb thiab cov cav uas tiv taus kub siab, kev tsim cov xov hlau winding tshiab yog qhov tseem ceeb.
