Yuav Ua Li Cas Xam Lub Hwj Chim Hluav Taws Xob
Yuav kom ntsuas thiab xam lub zog hluav taws xob, peb yuav tsum nkag siab txog ntau yam kev ntsuas yooj yim, uas yog voltage (V), current (I), thiab power factor (cos φ).
1. Xam Lub Zog Tiag: P = VI cos φ
Hauv kev xam suav, nws yog ib qho tseem ceeb heev uas yuav tsum xav txog qhov fais fab uas cuam tshuam txog qhov cuam tshuam ntawm theem tam sim no ntawm qhov hluav taws xob hauv AC (alternating current) system.
2. Xam Lub Hwj Chim Reactive: Q = VI sin φ
Qhov no feem ntau tsis quav ntsej hauv kev suav yooj yim, tab sis nws tseem ceeb heev uas yuav tsum xav txog hauv cov tshuab hluav taws xob nrog cov khoom siv inductive lossis capacitive.
3. Xam Lub Zog Pom Tseeb: S = VI
Nws muab ib daim duab dav dav ntawm qhov xav tau hluav taws xob ntawm lub cuab yeej hluav taws xob tsis hais seb lub zog puas yog tiag lossis reactive.
