Yuav ua li cas los xam lub tshuab hluav taws xob tam sim no uas qhov loj voltage ceramic capacitor tuaj yeem muab tau?
Ntau tus neeg siv khoom yuav nug peb: lub capacitor no tuaj yeem muab tau ntau npaum li cas tam sim no? Peb puas tuaj yeem them lub roj teeb?
Tseeb, high voltage ceramic capacitor tam sim no tuaj yeem suav tau. Cov mis tsis meej no yog I = 2 PI FCU
I: Tam sim no (A)
PIB: 3.1415926….
F: zaus, feem ntau 50HZ lossis 60HZ
C: muaj peev xwm (F)
U: voltage (V)
Hauv qab no, peb xam lub hwj chim ntawm high voltage condenser hom transformer
Piv txwv li ib yam khoom, qhov siab voltage sab yog 900PF / 10KV. Tsawg voltage sab yog 220V. zaus yog 50HZ, ces cov khoom tam sim no yog:
I=2*3.1415*50*900*10000/1000000000000=0.002827A
Vim li cas thiaj muab faib los ntawm 1000000000000? Qhov no yog vim 1F = 1000000000000PF, kaum ob xoom
Ua li no, thaum peb paub qhov tam sim no, thiab xav paub txog cov roj teeb them, nws yog qhov tseeb, piv txwv li, sab qis voltage yog 220V, ces lub hwj chim yog deb tshaj li 0.622W. ntawm cov neeg siv khoom xav tau ntawm 3W lub zog.
