Iintlobo capacitors: amandla kunye nobuthathaka

A capacitor yi kwizixhobo ze-elektroniki leyo ikuvumela ukugcina uze makanikelwe yokumpompoza sombane. Uphawu iphambili element umthamo wayo, nokumisela ukuxhomekeka isigxina ombane.

ngezigaba condensers

izixhobo ezahlukeneyo ukukhulula ubugcisa kuvumela ukuvelisa iintlobo ezahlukeneyo siyawazi. Xa umoya condensers ziquka amanqaku apho Heating na umoya. Izinto eziluncedo ze olu hlobo zixhobo lula ngawo. Ezi nkundla ke zenzelwe ukuba umthamo wolawulo ngoomatshini kwaye ziyilelwe ukuba ifuthe rhoqo ngoomatshini. Bobubi olu hlobo ibandakanya ukungazinzi, ukuthembeka amahlwempu, ukuxhomekeka ukufuma kunye lobushushu eliphakathi, ubukhulu becala, amandla aphantsi kakhulu Heating leyo anqongophele ngenxa yokuwa umoya phakathi utshonisa kunye capacitance ephantsi.

Kukho iindidi paper of capacitors, leyo isebenza njenge-oyile sombane Heating buzane iphepha. Ezi zixhobo kufuneka ube namandla eliphezulu Heating kunye nokuthembeka. Xa a ombane aphezulu , bona babe capacitance eliphezulu nezisezantsi ukuvuza yangoku.

capacitors abaninzi ziveliswa qho iphepha izityalo amandla. Ukuze wenze oku, ulisonge kunye amacwecwe amabini, phakathi apho ephepheni. Le fowuni ke waqengqela ube esongwayo baze bafakwe engqayini, nto leyo izaliswe ioli sombane kunye koko atywinwe. Bobubi ifowuni ziquka bubunzima obuninzi, aphezulu self-inductance kunye ukuxhathisa.

capacitors Electrolytic abe iintlobo Heating, zanikezelwa ngokwendlela i maleko oxide kwakheka kwi kumphezulu metal esebenzayo (ngokuqhelekileyo aluminium). Icebo eziveliswa ngokubeka kwindawo electrolyte eyenziwe i tape metal esebenzayo, komhlaba apho ifilim lithatyathwe oxide ixesha elide, uvumela ukuba ikheswa metal.

Olona phawu iphambili capacitors electrolytic kuba phambi kweentlobo wokwephuka, omnye ixabiso ukuba ukubamba ombane rated, yaye xa utshintsho batshatyalaliswa ngokukhawuleza. Oku kungenxa yokuba inkqubo yemichiza ezenzeka phakathi electrolyte kunye ipleyiti yesinyithi. Oksayidi film ngokuthe neentanda kunye breaks.

Noko ke, ngokuhambelana microcracks wokwephuka oluchanekileyo ngokukhawuleza liqiniswe oxide entsha. Izinto eziluncedo zezi zixhobo ziquka umthamo omkhulu, iintsilelo - wokwephuka, ukulahlekelwa impahla, wear ngokukhawuleza, inductance ephakamileyo yangaphakathi.

Iintlobo capacitors kunye izicelo zabo

Kukho kwakhona izixhobo apho lisebenza mica Heating, ezithi zisetyenziswe kufakelo ezahlukeneyo. Ekubeni kaMika kuphela ekwaziyo ukugcina amandla, ezi ntlobo capacitors babe capacitance eliphezulu namandla Heating. Bobubi ziquka parameters kozinzo, nonlinearity, ixabiso eliphezulu kwaye ukuxhomekeka ye capacitance yangoku.

Ngaphezu kusetyenziswe iintlobo yodongwe ka capacitors, ifilim, teflon, ezinepolypropylene kunye nezinye izixhobo.
