Ukuphawula capacitors - ukujongana njani?

Qho ngonyaka ngakumbi nangakumbi kwiimarike zasekhaya capacitors ingafumaneka kuphela eRashiya, kodwa amazwe. Kwaye abaninzi babanobunzima ezama iilebhile. ndifiumana njani oko? Enyanisweni, kwimeko yemposiso, kwaye kwidivayisi angazuza.

Okokuqala, siphawula ukuba ukumakishwa capacitors olwenziweyo kule ukuze:

1. Ubungakanani ukuthi angasebenzisa coded uphawu eyenziwa dijithi (rhoqo emithathu ukuya kwemine), kunye neeleta, apho incwadi ibonisa indawo enedesimali, uze notation (uF, nF, PF).
2. Ukuphambuka ovumelekileyo ukususela umthamo wesiqhelo (esetyenzisiweyo kwaye igqalwa ezinqabileyo, kuxhomekeka kwiimpawu kunye isixhobo khona).
3. Kuvumelekile ombane ulinganisele (kungenjalo ibizwa kuvumelekile ombane yokusebenza) - yinto parameter kubalulekile, ingakumbi xa esetyenziswa kwiisekethe eziphakamileyo-ombane).

Ukumakishwa kwe capacitors yodongwe e Ubungakanani

capacitors yodongwe okanye esisigxina ziphakathi kakhulu zithandwa. Ngokuqhelekileyo, capacitance uphawulo ingafunyanwa kwi umzimba, ungekho into ethile.

1. Ukukhetha capacitors of the amanani amathathu, swi zokuqala ezimbini apho mantissa kunye nobungakanani yokugqibela yi ixabiso kwisiseko 10 ukuya ukufumana ihlelo picofarads, ngamanye ibonisa inani amaqanda ukuba capacitor in pikafararadah. Umzekelo: 472 kuya kuthetha 4700 PF (endaweni 472 PF).

2. Ukuphawula capacitors lemivo ezine - inkqubo ngokufanayo edlulileyo, kodwa ke kule meko ezintathu zokuqala kubonisa mantissa, kwaye lokugqibela ixabiso isiseko 10 ukuya ukufumana ixabiso ubuso picofarads. Umzekelo: 2344 = 234 * 10 ² PF = 23400 PF = 23.4 nF;

3. enyama Ukuxuba okanye ngokuphawula amanani kunye neeleta. Kule leta meko ibonisa ukuba umba (uF, nF, PF), kwakunye ufumane indawo enedesimali, kunye namanani - ixabiso capacitance esetyenzisiweyo. Umzekelo: 28P = 28 PF 3n3 = 3.3 nF. Kukho amaxesha xa indawo enedesimali zibonakaliswe yileta R.

Ukumakishwa kwe parameter ombane yokusebenza kuvumelekile isoloko isetyenziswa kwindibano elektroniki, ezenziwe ngezandla zakhe. Oko kukuthi, ukuba kutywinwe iintanda of izibane ezibengezelayo akusayi kuba ngaphandle Ukukhethwa ombane efanelekileyo capacitors akuphumelelanga. Kwimeko enjalo, esi parameter ziya kuboniswa emva kuka kunye nesikhundla besiqhelo.

Ezi engundoqo parameters kusetyenziswa xa kumakishwa wenziwa capacitors. Kufuneka wazi xa ukhetha icebo efanelekileyo. Kophawu capacitors amazwe babe iiyantlukwano zabo, kodwa ngaphezulu ngokuhambelana echazwe bethu kweli nqaku.

Kakuhle capacitor ekhethiweyo kuya kukunceda ekudaleni izixhobo zakho, kwakunye negalelo ukulungisa zikhona. Eyona nto ibalulekileyo ukuze ukhumbule ukuba imveliso esemgangathweni kunokuba kuphela ukusuka kubenzi ezingqineke ukubaluleka kwabo kwimarike zombane. Kwaye olu hlobo umgangatho imveliso - ngaphezu kwayo yonke enye into. Ngapha koko, ngenxa yokuba kukho ukungasebenzi le capacitor lowanyathela kumacandelo izixhobo okanye isixhobo olubiza kakhulu. Kwakhona, ukuba baxhomekeke kukhuseleko lwakho.
