Ib lub capacitor yog ib qho ntawm cov khoom siv ntau tshaj plaws hauv txhua qhov hluav taws xob hluav taws xob. Analogues rau cov ntsiab lus tseem tsis tau tsim. Lawv zoo kawg nkaus khaws cov nqi thiab tuaj yeem muab nws tam sim ntawd. Yog tias qhov tso tawm tam sim ntawm 50 feem pua lossis ntau dua tuaj yeem ua mob rau lub roj teeb, ces qhov no yog hom kev ua haujlwm ib txwm muaj rau lub capacitor. Lub tsev txhab nyiaj capacitor muaj zog yog siv nyob rau hauv substations raws li kev them nyiaj rau lub zog reactive. Lawv nce cos φ ntawm kev lag luam kev lag luam thiab tuaj yeem hloov tau zoo, piv txwv li, lub tshuab hluav taws xob muaj zog uas raug tshem tawm ntawm kev ua haujlwm. Yog li, cov tsev txhab nyiaj muaj zog capacitor tau koom nrog hauv cov txheej txheem tsim khoom nws tus kheej. Lawv txhim kho cov khoom siv hluav taws xob zoo.
Cov khoom lag luam no muaj qhov chaw tsim nyog hauv hluav taws xob thiab. Nrog lawv cov kev pab, yuav luag tag nrho cov txheej txheem niaj hnub no tau ua tiav. Tab sis, hmoov tsis, cov qauv kuj muaj qee qhov tsis zoo. Peb tau accustomed los xav txog ib tug zoo tagnrho capacitor, uas yog devoid ntawm flaws thiab ua raws li tej yamkev cai lij choj hauv lawv txoj haujlwm, uas yooj yim piav qhia siv cov qauv lej. Hauv kev xyaum, txhua yam tshwm sim txawv. Qhov tshwm sim tam sim no tshwm sim - qhov teeb meem tseem ceeb rau ntau hom khoom siv no.
Nrog rau kev txhim kho thev naus laus zis rau kev tsim cov khoom no, tantalum capacitors tshwm sim. Lawv xyaum tsis muaj tag nrho cov teeb meem tseem ceeb uas muaj nyob rau hauv cov pa sib piv. Nyob rau hauv cov nqe lus ntawm lawv cov parameters, lawv yog ze li sai tau mus rau lub zoo tagnrho capacitor.
- Lawv muaj qhov xau qis heev, uas tso cai rau lawv siv rau hauv kev tsim cov khoom siv hluav taws xob muaj tseeb thiab tseem ceeb hauv cov khoom siv hluav taws xob.
- Tantalum capacitors tuaj yeem ua haujlwm zoo kawg nkaus hauv qhov kub thiab txias (ntawm -80 txog +125 ° C) thiab ntau zaus. Txawm li cas los xij, lawv qhov ntsuas tsis hloov.
- Muaj qhov ua haujlwm me me thiab inductance.
- Qhov cuam tshuam qis qis thiab cov cuab yeej impedance ntxiv rau tag nrho cov duab zoo.
Txawm li cas los xij, zoo li txhua yam khoom siv thiab cov khoom siv, tantalum capacitors muaj qee qhov tsis zoo. Nws yog ib qho tseem ceeb kom paub txog lawv thaum tsim hluav taws xob hluav taws xob.
-
smd tantalum capacitor Tantalum capacitor yog rhiab rau ntau tshaj qhov tseem ceeb hauv kev ua haujlwm. Tshwj xeeb, nws tsis pom zoo kom dhau (txawm luv luv) qhov ntsuas hluav taws xob uas lub cuab yeej no tau tsim.
- Cov thev naus laus zis ntawm lawv cov khoom siv yog qhov nyuaj heev thiab muaj ntau theem. Txawm tias me ntsis sib txawv los ntawm nws los yog siv cov khoom tsis zoocov ntaub ntawv raw ua rau muaj kev hloov pauv ntawm cov khoom siv.
- Tus nqi siab txaus ntawm lub capacitor yog txoj hauv kev ncaj qha kom nce tus nqi ntawm tag nrho cov hluav taws xob hluav taws xob (qhov no yuav cuam tshuam rau qhov kwv yees).
Nws tseem yuav tsum tau coj mus rau hauv tus account tias qhov cim ntawm tantalum capacitors muaj nws tus yam ntxwv. Nws xyaum tsis txawv ntawm lwm yam khoom siv. Tab sis qhov no tsuas yog siv rau cov capacitor tsis ntev los no. "Kub" capacitors yog xim-coded, qhov kev txiav txim siab uas yooj yim mus nrhiav hauv Web. Tsis tas li ntawd, nws yuav tsum nco ntsoov tias smd tantalum capacitors tau cim nrog cov lej cim. Yog tias koj tsis yog tus kws tshaj lij hauv cov cuab yeej no - nrog tus muag khoom thaum yuav. Cov ntaub ntawv yooj yim saum toj no yuav tso cai rau koj nug cov lus nug tseem ceeb.
