Kodi capacitor, ndipo kodi ndi chifukwa

Pofotokoza zimenezi capacitor, tiyenera kumvetsa bwino lomwe chifukwa thupi ntchito ndi kapangidwe ka zinthu singasiyanitsidwe iliyonse yaikulu kwambiri kapena zochepa chipangizo zamagetsi.

Condenser - ndi mchitidwe wa dera magetsi, wopangidwa mwa mbale awiri conductive, omwe limapangidwa zosiyana chizindikiro magetsi mlandu. Mbale ankasiyana insulator, chimene chimawathandiza kukhalabe mlandu.

Pali mitundu ingapo ya zipangizo kutchinjiriza ntchito capacitors, kuphatikizapo ziwiya zadothi, Mica, tantalum ndi polystyrene. Chimagwiritsidwa ntchito kupanga capacitors ndi insulators monga mpweya, pepala ndi pulasitiki. Aliyense wa zinthuzi bwino kumathandiza capacitor mbale asanakumane ndi mzake.

Kodi capacitor?

Mawu akuti "capacitor" amadziwika umatha kusunga mlandu magetsi. Unit wa capacitance ndi Farad.

Ngati masitolo capacitor mlandu 1 m'khosi pa kusiyana ulipo pakati pa mbale wake 1 Volt, ndiye ali ndi phindu mphamvu farad wina. Ndipotu, gulu ili ndi chachikulu ntchito othandiza kwambiri. Chitsanzo capacitance makhalidwe ntchito capacitors kugwa mu ranges milifarad (10.3 F) microfarads (10-6 F) ndi picofarads (10-12 F).

ndi capacitors chiyani?

Kuti kumvetsa zomwe capacitor, m'pofunika kuganizira Mitundu ya chigawo ichi, malingana ndi cholinga, zikhalidwe za ntchito ndi mtundu wa dielectric.

capacitors Electrolytic ntchito m'madera kumene mphamvu mkulu chofunika. Ambiri a zinthu izi ndi kumalo ozizira. zipangizo ochiritsira kwa iwo - kapena tantalum zotayidwa. Zotayidwa Electrolytic capacitors ndi mtengo kwambiri ndi zambiri ankagwiritsa ntchito. Komabe, tantalum ndi zayamba wamkulu volumetric Mwachangu ndi ndi makhalidwe kwambiri magetsi.

Tantalum capacitors ndi monga dielectric wa okusayidi tantalum. Mkulu kudalirika makhalidwe abwino pafupipafupi, osiyanasiyana kutentha ntchito. Iwo ankagwiritsa ntchito zipangizo zamagetsi kumene mkulu mlingo wa mphamvu pa miyeso yaing'ono. Chifukwa cha ubwino wake amapangidwa lalikulu zedi zosowa za makampani zamagetsi.

The kuipa capacitors tantalum akhoza zimachitika tilinazo wa zimachitika-panopa ndi pa-voteji, ndi wachibale kukwera mtengo kwa mankhwala amenewa.

Mphamvu capacitors amagwiritsidwa ntchito mu kachitidwe mkulu voteji. Iwo ankagwiritsa ntchito kukwaniritsa zomvetsa mu mizere mphamvu, ndi kusintha mphamvu imayambitsa makhazikitsidwe mafakitale. Zopangidwa mkulu-metallized polypropylene filimu ndi ntchito yapadera sanali poizoni impregnation ndi chimateteza mafuta.

Mwina ndi kudziononga wokha Mbali kuvulala mkati, zomwe zimawachititsa chitetezo zina ndi kuonjezera moyo utumiki.

capacitors Ceramic mfundo dielectric monga ceramic. Iwo yodziwika ndi magwiridwe mkulu wa voteji opaleshoni, kudalilika, imfa otsika mtengo wotsika.

Osiyanasiyana makhalidwe awo kuyambira ndi picofarads zochepa za 0,1 microfarads. Iye panopa ndi imodzi mwa ambiri ankagwiritsa ntchito mitundu ya capacitors ntchito zipangizo zamagetsi.

Silver Mica capacitors m'malo ambiri m'mbuyomu zinthu Mica. Ndi kukhazikika mkulu, ndi nyumba hermetic ndi mphamvu yaikulu pa wagawo buku.

Ponseponse ntchito capacitors siliva Mica zimawalepheretsa ndi mtengo.

Mu pepala ndi metallized capacitor elekitirodi unapangidwa woonda aluminum zojambulazo, komanso dielectric, pepala lapadera impregnated olimba (osungunula) kapena dielectric madzi. Iwo ntchito mu madera wailesi otsika-pafupipafupi pa mafunde mkulu. Iwo ali ndi wotchipa.

Chifukwa kufunika capacitor ndi

Pali zitsanzo za ntchito capacitors zosiyanasiyana za cholinga chake. Makamaka, iwo ankagwiritsa ntchito kusungiramo wa chizindikiro analogi ndi digito ndi deta. capacitors variable ntchito kutumiza mauthenga kwa kusintha pafupipafupi ndi khwekhwe zida telefoni.

Chitsanzo chabwino cha ntchito zawo ndi ntchito magwero mphamvu. Kumeneko, zinthu izi kuchita ntchito ya kuwongola (zosefera) wa voteji kudzatha pa linanena bungwe la zipangizozi. Angagwiritsidwenso ntchito kuchulukitsa voteji kwa kupoletsa mkulu voteji, kupyoza kangapo athandizira voteji. Condensers ankagwiritsa ntchito mitundu yosiyanasiyana ya converters voteji, uninterruptible magetsi zipangizo makompyuta, etc.

Pofotokoza kuti capacitor zimenezi, sitingathe kunena kuti chinthu ichi angathe kutumikira monga zapamwamba kwambiri za ma elekitironi. Komabe, kwenikweni nchito imeneyi ali ndi zofooka zina chifukwa makhalidwe sanali abwino a ntchito chimateteza dielectric. Komabe, capacitor ali chuma motalika kokwanira kusunga mphamvu ngati zamagetsi pamene sakukhudzidwa ndi dera cholusa, choncho angagwiritsidwe ntchito kwa kanthawi mphamvu zoyendetsera.

Chifukwa katundu wake wapadera thupi la zinthu izi zinali choncho chimagwiritsidwa ntchito mu makampani a pakompyuta ndi magetsi, zomwe lero kawirikawiri china chilichonse magetsi sakhala ndi chimodzi ngati chigawo cha cholinga chilichonse.

Polongosola mwachidule, tikhoza kunena kuti capacitor - ndi gawo lofunika kwambiri kwa yaikulu zosiyanasiyana zamakono ndi magetsi, popanda zomwe pakadakhala Sindingachite patsogolo kwa sayansi.

Ndizimene capacitor!
