Lub rwb thaiv tsev tsis kam ntawm lub cev muaj zog yog qhov tseem ceeb rau kev ntsuas nws cov kev ua haujlwm rwb thaiv tsev, uas yog ncaj qha ntsig txog kev nyab xeeb ntawm lub cev muaj zog. Vim muaj ntau hom thiab voltage theem ntawm cov motors, cov qauv yam tsawg kawg nkaus rau kev rwb thaiv tsev kuj tseem sib txawv.
Rwb thaiv tsev tsis kam ntawm low-voltage motors
Rau low-voltage motors nrog voltage theem ntawm 400V thiab hauv qab no, yam tsawg kawg nkaus tus qauv rau rwb thaiv tsev tsis kam yog raws li nram no:
Cov kab tshiab tshiab: Cov rwb thaiv tsev tiv thaiv ntawm kab thiab nruab nrab ntawm cov kab thiab hauv av yuav tsum tsis txhob tsawg dua 0.5 megohms.
Cov khoom siv thiab cov kab hauv kev ua haujlwm: Cov rwb thaiv tsev tiv thaiv yuav tsum tsis pub tsawg dua 1 megohm / kilovolt, lossis sib npaug rau 1 kiloohm / volt.
Rwb thaiv tsev tsis kam ntawm me me thiab nruab nrab motors
Rau cov motors me me thiab nruab nrab, qhov tsawg kawg nkaus tus qauv rau rwb thaiv tsev kuj tsis tsawg tshaj li 0.5 megohms. Cov txheej txheem no siv rau cov khoom siv thiab cov kab hauv kev ua haujlwm, thiab cov rwb thaiv tsev yuav tsum tsis txhob tsawg dua 1MΩ / kV.
Rwb thaiv tsev tsis kam ntawmhigh-voltage hluav taws xob lub cev muaj zogs
Lub rwb thaiv tsev tiv thaiv kev xav tau rau high-voltage motors yog nruj dua. Cov qauv tshwj xeeb yog raws li hauv qab no:
Stator rwb thaiv tsev tsis kam: ntawm kev khiav hauj lwm kub, lub rwb thaiv tsev kuj yuav tsum tsis txhob tsawg tshaj li 1 megohm ib kilovolt.
Rotor rwb thaiv tsev tsis kam: Nws cov rwb thaiv tsev yuav tsum tsis pub tsawg tshaj 0.5 megohms ib kilovolt.
Kev ntsuas ntawm lub cev muaj zog rwb thaiv tsev tsis kam
Thaum ntsuas qhov rwb thaiv tsev ntawm lub cev muaj zog, tej zaum yuav muaj qee qhov sib txawv vim qhov kev siv ntawm cov qauv sib txawv thiab kev cuam tshuam ntawm cov yam ntxwv xws li qhov kub thiab txias thiab qhov sib nqus nqus. Tshwj xeeb tshaj yog thaum cov nqi hluav taws xob tiv thaiv kev tiv thaiv thiab kev nqus qhov sib piv yog ze rau qhov tseem ceeb, cov txiaj ntsig ntawm cov neeg ua haujlwm sib txawv yuav txawv. Yog li ntawd, thaum ntsuas, cov kev cai cuam tshuam yuav tsum tau ua raws li nruj me ntsis, cov cuab yeej tsim nyog yuav tsum raug xaiv, thiab cov kev txwv sib txawv rau cov xeev txias thiab kub yuav tsum tau paub qhov txawv.
Hauv cov ntsiab lus, qhov tsawg kawg nkaus kev tiv thaiv kev tiv thaiv ntawm lub cev muaj zog nyob ntawm nws qhov voltage thiab hom. Kev rwb thaiv tsev tsis zoo ntawm cov tshuab hluav taws xob tsawg thiab cov motors me me thiab nruab nrab /nruab nrab voltage induction lub cev muaj zog feem ntau yuav tsum tsis pub tsawg tshaj 0.5 megohms, thaum lub rwb thaiv tsev tiv thaiv ntawm high-voltage motors yuav tsum tsis txhob tsawg tshaj li 1 megohm ib kilovolt. Cov qauv no yog tsim los xyuas kom meej tias lub cev muaj zog yuav tsis ua rau muaj kev nyab xeeb vim tsis muaj rwb thaiv tsev thaum ua haujlwm.
