Yuav ua li cas ntsuas qhov kev tiv thaiv ntawm cov coils ntawm peb-theem lub cev muaj zog siv lub multimeter's resistance range
Cov theem tsis kam ntawm lub cev muaj zog tsis tuaj yeem ntsuas nrog megger vim tias qhov hluav taws xob ntawm lub megger siab dhau lawm, uas tuaj yeem tawg los ntawm kev rwb thaiv tsev ntawm lub kauj. Feem ntau, peb siv multimeter los ntsuas qhov tsis kam ntawm coils ntawm peb-theem lub cev muaj zog. Txawm hais tias nws yog lub hnub qub kev sib txuas lossis kev sib txuas ntawm lub kaum sab xis, qhov kev tiv thaiv ntawm peb theem windings yuav tsum yog me me, thiab cov windings yog qhov qub.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias peb-theem windings tau sib xyaw ua ke. Tsuas yog cov motors nrog lub zog me me uas txuas nrog sab hauv lub hnub qub lossis daim duab peb sab, lub zog hluav taws xob siab xav tau cov ntawv sib txuas rau kev sib txuas lossis siv lub hnub qub delta voltage txo kev tswj cov thaiv. Yog tias cov ntawv sib txuas raug tshem tawm, qhov kev tawm tsam ntawm peb-theem windings yuav tsum siab dua ib megaohm.
Yog li, thaum ntsuas tus nqi tsis kam ntawm peb-theem winding, peb yuav tsum tshem tawm cov khoom sib txuas kom tau txais cov ntaub ntawv raug.
Qhov rwb thaiv tsev ntawm peb-theem winding rau hauv av tuaj yeem ntsuas tau siv lub megohmmeter, uas feem ntau yog qhov tsis muaj qhov kawg thiab yuav tsum muaj tsawg kawg yog ntau dua 0.5 megohms. Qhov loj dua lub cev muaj zog, qhov siab dua qhov kev tiv thaiv kev tiv thaiv. Rau 45 kW lub cev muaj zog, cov rwb thaiv tsev yuav tsum muaj ntau tshaj li ib megohm.
Cov rwb thaiv tsev rau hauv av hais txog ntawm no yog hais txog kev sib txuas ntawm cov winding thiab lub cev lub cev, tsis yog cov rwb thaiv tsev rau hauv av xaim lossis hauv av. Yog li thaum peb ntsuas, peb tsuas yog yuav tsum ntsuas qhov tsis kam ntawm winding thiab lub cev.
