Dab tsi yog qhov sib txawv ntawm 220v thiab 380v rau qhov kub kub lub kauj roj cua sov? Puas yog cov teeb meem no uas cov neeg siv khoom feem ntau ntsib thaum siv lawv, puas cuam tshuam rau qhov kub? Puas yog lub zog siv hluav taws xob sib txawv? Qhov twg yog qhov zoo?
1. Raws li kev xa tawm ntawm lub hwj chim tib yam, raws li Ohm txoj cai: P = UI, piv txwv li lub zog (Watt) = voltage (volts) * tam sim no (A). Cov khoom lag luam nws tus kheej tsis hloov, qhov ntsuas rated tsis kam ntawm cua sov lub raj yog tas mus li, nws tuaj yeem pom tseeb tias qhov tam sim no thaum siv 220v thiab 380v yog qhov sib txawv.
2, lub kauj cua sov hluav taws xob tam sim no sib txawv, qhov yuav tsum tau siv cable tuab tsis zoo ib yam, qhov ntsuas hluav taws xob, hloov hluav taws xob, ntsuas qhov ntsuas, thiab lwm qhov txuas hluav taws xob kuj yog cov kev xaiv sib txawv, saum toj no yog qhov sib txawv ntawm cov cua sov raj 220v thiab 380v.
Qhov ntsuas kub, cua sov tus nqi thiab siv hluav taws xob muaj feem xyuam rau lub hwj chim. Cov cua kub ua rau ntawm tib lub zog thiab cov ntsuas hluav taws xob sib txawv yog tib yam. Kev siv hluav taws xob thaum siv tib lub sijhawm ua haujlwm yog tib yam. Rau kev nyab xeeb, kev cuam tshuam voltage yog tib yam. Tsis loj.
Peb yuav tsum paub ntau npaum li cas siv hluav taws xob siv hauv qhov hluav taws xob coil, uas muaj feem xyuam rau cov hwj huam ntsuas thiab lub sijhawm siv.
1 kW lub tshuab hluav taws xob cua sov ua haujlwm ib zaug ib teev,
Piv txwv li, lub tshuab hluav taws xob kub uas siv tau 400 watt siv rau 400/1000 = 0.4 kWh rau ib teev, thiab 1000 kW = 2.5 kWh rau 1 teev.
Nco tseg:
(1) kilowatt yog chav ua haujlwm fais fab, cim: kw
(2) Watt yog lub zog ua haujlwm, cim: w
(3) 1 kW = 1000 watts
(4) 1 kWh = 1 kWh
