Yuav ua li cas yog ib tug capacitor, thiab dab tsi yog nws rau

Piav qhia hais tias xws li ib tug capacitor, peb yuav tsum to taub meej lub cev hauv paus ntawm kev ua hauj lwm thiab cov qauv ntawm cov yam tseem ceeb ntawm txhua txhua ntau dua los yog tsawg loj heev ntawm cov hluav taws xob ntaus ntawv.

Condenser - yog ib lub caij uas ib tug hluav taws xob Circuit Court, muaj ob conductive daim hlau, txhua tus uas muaj opposite kos npe rau hluav taws xob xwb. Daim Hlau sib cais los ntawm ib tug insulator, uas yuav pab lawv kom muaj tus nqi.

Muaj ob peb hom ntawm rwb thaiv tsev ntaub ntawv siv nyob rau hauv capacitors, xws li ceramics, mica, tantalum thiab polystyrene. Lug siv nyob rau hauv qhov siv thiab ua capacitors thiab xws li insulators li huab cua, daim ntawv thiab yas. Txhua yam ntawm cov ntaub ntawv zoo tsis pub cov capacitor daim hlau los ntawm kev sib cuag nrog txhua lwm yam.

Yuav ua li cas yog ib tug capacitor?

Lub sij hawm "capacitor" characterizes nws muaj peev xwm cia hluav taws xob xwb. Lub tsev ntawm capacitance yog Farad.

Yog hais tias lub khw muag khoom noj capacitor them 1 pendant ntawm ib tug tej zaum txawv nruab nrab ntawm nws daim hlau 1 volt, ces nws muaj lub peev xwm nqi ntawm ib tug farad. Nyob rau hauv qhov tseeb, qhov no unit yog loj heev rau feem ntau cov tswv yim daim ntawv sau npe. Raug capacitance qhov tseem ceeb siv capacitors poob nyob rau hauv lub hom twg milifarad (10.3 F) microfarads (10-6 F) thiab picofarads (10-12 F).

Yuav ua li cas yog cov capacitors?

Yuav kom to taub li cas ib tug capacitor, nws yog tsim nyog los xav txog lub theem pib hom ntawm no tivthaiv, nyob ntawm seb lub hom phiaj, tej yam kev mob ntawm daim ntawv thov thiab tej hom kev dielectric.

Electrolytic capacitors yog siv nyob rau hauv circuits qhov twg muaj peev xwm yog yuav tsum tau. Feem ntau ntawm cov ntsiab yog polar. Pa cov ntaub ntawv rau lawv - los yog tantalum txhuas. Aluminium Electrolytic capacitors yog npaum li cas pheej yig dua thiab ntau lug siv. Txawm li cas los, tantalum muaj ib tug tshuam ntau dua volumetric efficiency thiab muaj zoo heev hluav taws xob yam ntxwv.

Tantalum capacitors muaj raws li ib tug dielectric ntawm tantalum oxide. High cia siab rau, zoo zaus yam ntxwv, ib tug ntau ntawm cov kev khiav hauj lwm kub. Lawv yog lug siv nyob rau hauv hluav taws xob cov khoom uas ib theem siab ntawm muaj peev xwm ntawm me me qhov ntev. Vim hais tias ntawm nws cov zoo yog ua nyob rau hauv loj qhov ntau rau cov kev xav tau ntawm cov electronics kev lag luam.

Qhov tsis zoo ntawm tantalum capacitors yuav tsum tau ntaus nqi rau qhov rhiab heev ntawm tus mem tes-tam sim no thiab dhau-voltage, thiab cov txheeb ze nqi ntawm cov khoom no.

Fais fab capacitors yog feem ntau siv nyob rau hauv high voltage tshuab. Lawv yog lug siv pab kom txawm peem rau losses nyob rau hauv hwj chim kav, thiab los txhim kho lub hwj chim tshaj nyob rau hauv industrial sib. Ua los ntawm high-metallized polypropylene zaj duab xis nrog rau kev siv tshwj xeeb uas tsis yog-tshuaj lom impregnation nrog insulating roj.

Tej zaum yuav muaj ib tug self-destruct feature nrog kev raug mob, uas muab lawv ntxiv kev ruaj ntseg thiab tsub kom cov kev pab cuam lub neej.

Ceramic capacitors muaj dielectric khoom raws li tej hub. Lawv tsiag ntawv los ntawm high functionality ntawm cov kev khiav hauj lwm voltage, kev cia siab, tsis muaj poob thiab tus nqi qis.

Cov kab kev los ntawm lawv daim ntawv Tuition Waiver xws li los ntawm ib tug ob peb picofarads mus txog 0.1 microfarads. Nws yog tam sim no ib tug ntawm cov feem ntau lug siv hom capacitors siv nyob rau hauv hluav taws xob cov khoom.

Nyiaj mica capacitors hloov ntau yav dhau los mica ntsiab. Muaj lub siab stability, ib tug hermetic vaj tse nyob thiab ib tug loj muaj peev xwm ib chav tsev ntim.

Thoob plaws siv cov nyiaj mica capacitors tiv thaiv lawv kuj kim heev.

Nyob rau hauv daim ntawv thiab metallized capacitor electrode ua los ntawm ib tug nyias txhuas ntawv ci, raws li zoo raws li ib tug dielectric, ib tug tshwj xeeb daim ntawv impregnated khoom (molten) los yog kua dielectric. Lawv yog siv nyob rau hauv tsawg zaus xov tooj cua circuits nyob rau high school currents. Lawv yog cov kuj pheej yig.

Yog vim li cas qhov yuav tsum tau rau ib tug capacitor

Muaj ib tug xov tooj ntawm cov piv txwv ntawm kev siv ntawm capacitors nyob rau hauv ib tug ntau yam ntawm lub hom phiaj. Nyob rau hauv kev, lawv yog lug siv rau lub cia ntawm analog Pib ntsais koj teeb thiab cov thiab cov ntaub ntawv. Kuj tsis paub meej capacitors yog siv nyob rau hauv telecommunications rau zaus hloov thiab teeb ntawm telecommunication khoom.

Ib tug raug piv txwv ntawm lawv daim ntaub ntawv yog kev siv ntawm lub hwj chim qhov chaw. Muaj, cov ntsiab ua cov kev ua ntawm smoothing (filtering) ntawm lub rectified voltage ntawm cov qhov tso zis ntawm cov pab kiag li lawm. Tej zaum lawv kuj yuav siv tau nyob rau hauv lub voltage multipliers rau generating high voltage, tshaj ob peb lub sij hawm lub tswv yim voltage. Condensers yog lug siv nyob rau hauv ntau hom ntawm voltage converters, uninterruptible mov fais fab pab kiag li lawm rau computers, thiab lwm yam

Piav qhia hais tias xws li ib tug capacitor, peb tsis tau hais tias qhov no caij yuav tau pab raws li ib qho zoo heev repository ntawm electrons. Txawm li cas los, nyob rau hauv kev muaj tiag no muaj nuj nqi muaj tej yam kev txwv vim tsis yog-zoo tagnrho cov yam ntxwv ntawm cov ua hauj lwm insulating dielectric. Txawm li cas los, cov capacitor muaj cov cuab yeej ntev txaus rau cia hluav taws xob lub zog thaum kaw ntawm lub teeb uas them Circuit Court, li ntawd, nws yuav siv tau raws li ib tug ib ntus hwj chim qhov twg los.

Vim nws cov cim lub cev thaj chaw ntawm cov ntsiab tau li lug siv nyob rau hauv lub tshuab hluav taws xob thiab hluav taws xob kev lag luam, uas niaj hnub no tsis tshua muaj tej hluav taws xob khoom tsis muaj tsawg kawg yog ib tug xws li kev tivthaiv rau tej hom phiaj.

Summing li, peb yuav hais tias cov capacitor - yog ib invaluable ib feem ntawm lub loj loj ntau yam hluav taws xob thiab hluav taws xob pab kiag li lawm, tsis muaj uas nws yuav tau unthinkable ntxiv kev kawm nyob rau hauv science thiab technology.

Hais tias yog dab tsi ib tug capacitor!
