Yog tias koj xav kho cov khoom siv hluav taws xob hluav taws xob, koj yuav tsum paub cov kev txwv no: qhov hluav taws xob, lub zog, qhov loj, siv ib puag ncig thiab qhov chaw teeb tsa. Voltage ranked thawj ntawm ob peb tsis, uas qhia nws qhov tseem ceeb. Kev txiav txim siab ntawm qhov hluav taws xob ncaj qha cuam tshuam rau lub neej kev pab cuam ntawm hluav taws xob cua sov. Peb cov voltages feem ntau yog 220V thiab 380V, yog li qhov txawv ntawm 220V thiab 380V yog dab tsi?
Dab tsi yog qhov txawv ntawm 220V thiab 380V hluav taws xob rhaub? Lub 220V thiab 380V voltages hais ntawm no xa mus rau qhov ntsuas hluav taws xob, uas yog, qhov hluav taws xob ntawm hluav taws xob cua sov. Qhov hluav taws xob no tsis zoo ib yam li lub zog hluav taws xob siv hluav taws xob siv.
1.txoj kev sib txawv:
Yog tias ib lub tshuab rhaub hluav taws xob yog 220V, nws tsuas yog tuaj yeem txuas nrog 220V, yog tias nws txuas nrog 380V, lub zog yuav loj dua thiab tej zaum nws yuav fused thiab tawg.Yog tias nws yuav tsum tau txuas nrog 380V, lub rhaub cov khoom yuav tsum muaj 3 tubular. cua sov pas nrig thiab siv lub hnub qub txuas.
Yog tias ib lub rhaub hluav taws xob yog 380V, yog li nws tuaj yeem txuas nrog 380V thiab 220V, tab sis thaum nws txuas nrog 220V voltage, lub zog yuav me dua.
2.Resistance yog txawv:
Yog hais tias qhov voltage yog 220V, tus nqi kuj yog 220 * 220 / 2000 =24.2Ω
Yog hais tias qhov voltage yog 380V, tus nqi kuj yog 380 * 380 / 2000=72.2Ω
Tus nqi sib txawv ntawm qhov sib txawv txhais tau hais tias qhov sib txawv ntawm cov kab hluav taws xob thiab cov coil no.
