Cov qhov ntsuas voltage qhia peb tias qhov kev nyab xeeb siab tshaj qhov sib txawv yog dab tsi, qhov rwb thaiv tsev hauv qhov ntawd capacitor tuaj yeem lis ua ntej lub rwb thaiv tsev tawg thiab cov capacitor ua tsis muaj txiaj ntsig. A 250V, 50Hz mov yog siv thoob plaws a capacitor ntawm 1/314 farad.

Tsuas yog li ntawd, kuv puas tuaj yeem siv lub capacitor nrog qhov ntsuas hluav taws xob ntau dua?

Feem ntau hais lus tsis muaj teeb meem siv capacitors ntawm a siab dua voltage ntsuas . Yog koj siv cov capacitors ntsuas rau siab dua voltage , cov no feem ntau loj dua ua tau Qhov ntau thiab tsawg, uas txhais tau tias qis ESR, yog li hauv qee qhov xwm txheej ESR tuaj yeem poob qis dua qee qhov kev nyab xeeb thiab tom qab ntawd tus tswj hwm kab yuav tsis ruaj khov.

Tsis tas li ntawd, dab tsi yog qhov voltage ntawm lub capacitor? Cov hluav taws xob kev ntsuam xyuas ntawm a capacitor yog ib qho kev ntsuas ntawm nws cov rwb thaiv tsev muaj zog npaum li cas. Lub hau 35V tuaj yeem tiv taus yam tsawg 35 hluav taws xob siv hla nws (ntau dua hluav taws xob tej zaum yuav ua rau tej yam phem xws li luv luv los ntawm lub hau thiab burnup).

Tsis tas li ntawd paub, puas qhov voltage tseem ceeb ntawm capacitor?

A capacitor nrog rau qhov ntsuas 50V lossis siab dua yuav raug siv. A capacitor tej zaum yuav muaj qhov ntsuas 50-volt tab sis nws yuav tsis them txog 50 volts tshwj tsis yog tias nws tau pub 50 volts los ntawm DC fais fab mov. Cov hluav taws xob qhov ntsuas tsuas yog qhov siab tshaj plaws xwb hluav taws xob tias a capacitor yuav tsum raug nthuav tawm, tsis yog hluav taws xob tias cov capacitor yuav them mus txog.

Yuav ua li cas yog tias koj siv lub capacitor siab dua?

Nws yuav sai sai no hlawv. Yog hais tias capacitance ntawm capacitor nce ces them ntau lawm ib voltage rau capacitor tseem yuav nce ntxiv uas tig tawm mus rau hauv siab kub hauv kev pib windings uas yuav hlawv tawm qhov pib winding.
