Ib lub capacitor yog ib feem tseem ceeb ntawm txhua yam khoom siv hluav taws xob, tab sis qee zaum nws tshwm sim tias qhov tsis ua tiav nrog qhov tseem ceeb tshaj plaws ntawm lub cev. Hauv kab lus no peb yuav tham txog vim li cas cov capacitors ntawm lub motherboard yog o.
Lub capacitor zoo li lub roj teeb, qee zaum me ntsis flattened vertically. Sab hauv yog ib lub yob me me ntawm txhuas ntawv ci hauv cov tshuaj electrolyte (anode thiab cathode). Aluminium ntawv ci yog insulated los ntawm electrolyte nrog nyias oxidized zaj duab xis dielectric.
Lub hom phiaj tseem ceeb ntawm cov khoom siv hluav taws xob yog hloov pauv tam sim no los ntawm qhov hluav taws xob mus rau qhov hluav taws xob ncaj qha, tsim nyog rau nws cov zaus Circuit Court, nrog rau kev sib hloov ntawm qhov sib kis ntawm qhov hluav taws xob.
Cov kev hloov pauv no tseem hu ua ripple rau lwm txoj hauv kev. Lawv ua rau lub condenser cua sov, thiab qhov lawv muaj zog, qhov kub yuav nce siab.
Cas of blown capacitors
Lub capacitor o yog ib qho ntawm feem ntau ua rau cov khoom siv hluav taws xob tsis ua hauj lwm, thiab hauv cov ntsiab lus, tsis ua hauj lwm ntawm hluav taws xob Circuit Court. Kev nqhis dej feem ntau tshwm sim hauv lub zog hluav taws xob, nrog rau hauv cov khoom siv hluav taws xob lawv tus kheej.
Muaj ntau yam laj thawj vim li cas capacitors swell - los ntawm cov khoom siv tsis zoo thiab kev puas tsuaj rau microcircuit, hnav thiab tsim kua muag thiab hluav taws xob tawm.
Los ntawm qhov pom tseeb tshaj plaws thiab feem ntau ua rau, ib ntu ntawm cov xwm txheej tuaj yeem paub qhov txawv: cov cua kub ntau dhau (siv cua sov) thiab tom qab evaporation ntawm cov kua electrolytic los ntawm lub tank capacitor.
Nyob zoo
Qhov tshwm sim txaus ntshai tshaj plaws ntawm cov laj thawj yog vim li cas capacitors swell yog qhov zoo ntawm qhov hluav taws xob nkag rau hauv Circuit Court. Yog hais tias nws tsis yog Ameslikas muab rau lub capacitor nyob rau hauv cov ntaub ntawv no tshwj xeeb, nws yuav tsum tau ua hauj lwm nyob rau hauv ib tug nce hom.
Yog li ntawd, lub luag haujlwm tseem ceeb ntawm cov tuam txhab ntawm microcircuits, xws li cov motherboards rau cov khoos phis tawj, yog los laij cov qauv yooj yim thiab muaj peev xwm thauj khoom hauv lub network thiab nruab capacitors nrog lub zog reactive txaus (analogous rau bandwidth) uas tuaj yeem tiv taus qhov hluav taws xob surges lossis tua lawv tus kheej.
Thiab lawv ua tiav, txwv tsis pub cov capacitors ntawm lub motherboard yuav swell hauv ib teev.
Nws tsis tuaj yeem tshem tawm qhov tsis xws luag, uas, raws li, muaj lub neej ua haujlwm luv dua thiab qis qis ntawm kev sib txawv ntawm hom kev ua haujlwm yooj yim - lawv ua kom sov sai dua thiab muaj zog dua.
Nco ntsoov, yog tias koj pub cov khoom siv hluav taws xob tsis zoo nrog qhov zootam sim no, nws yuav ua hauj lwm rau tag nrho lub sij hawm tshaj tawm thiab yuav tsis pom cov cim ntawm ib tug malfunction, tab sis kiag li tsis muaj dab tsi tshwm sim, thiab lub hwj chim surges tsis txawv.
Yog li ntawd, cov khoom siv hluav taws xob tas li ua haujlwm nyob rau hauv ib puag ncig hnyav. Xws li kev ua haujlwm yuav tsum ua rau cua sov, uas yuav maj mam evaporate cov kua electrolytic los ntawm lub tank capacitor, uas nyob rau yav tom ntej yuav ua rau o.
Evaporation ntawm electrolyte
Ib yam kua uas muaj cua sov txaus pib boil. Dej hloov mus rau hauv chav thiab evaporates, thiab cov kua electrolytic tsis muaj qhov zam.
Feem ntau, capacitors swell precisely vim tsis muaj electrolyte, thiab yog vim li cas rau qhov no tej zaum yuav yog lawv cov reactive hwj chim tsis txaus, tsis zoo ntawm cov ntaub ntawv, raws li zoo raws li banal lub cev hnav ntawm lub capacitor nws tus kheej, ua rau nws. ua kom kub ntau ntxiv.
Tsis tshua muaj, cov cua sov sab nraud tuaj yeem ua rau, nrog rau qhov tsis raug polarity.
Hloov o capacitors
Txhua tus neeg siv khoom uas nkag siab txog kev sau npe ntawm cov khoom siv hluav taws xob lossis tuaj yeem nrhiav cov ntaub ntawv ntawm lub cuab yeej uas nws tau nruab yuav hloov nws li ob peb feeb. Cov txheej txheem suav nrog desoldering Conder qub thiab soldering hauv qhov tshiab.
Kev tiv thaiv kev ua haujlwm ntawm lub capacitor
Nws tuaj yeem tiv thaiv qhov o ntawm cov capacitors hauv tsev, piv txwv li, ntawm lub computer motherboard, nrog kev pab los ntawm qee yam kev ntsuas. Cov no suav nrog:
- Nruab cua txias ntxiv hauv chav tsev.
- Txhim "Power Cutoff" yam tsawg kawg ntawm lub qhov hluav taws xob uas ua rau lub PC.
- Siv cov xaim zoo, cov qhov (socket), cov lim fais fab.
- Siv lub hwj chim zoo.
- Yuav khoom UPS.
Tseem muaj cov khoom tshwj xeeb silicon capacitors. Lawv swell tsawg dua, tab sis lawv cov nqi yog qhov kev txiav txim siab dua, thiab lawv tsis haum txhua qhov chaw, vim tias lawv muaj qhov sib txawv ntawm cov sinusoid.
