Inyungu nini ya capacitori ya firime ya organometallic nuko yikiza, bigatuma izo capacator ziba imwe mumashanyarazi yihuta cyane muri iki gihe.

Hariho uburyo bubiri butandukanye bwo kwikiza ibyuma bifata ibyuma: kimwe ni ugusohora kwikiza;ikindi ni amashanyarazi yo kwikiza.Iyambere iboneka kuri voltage ndende, bityo nayo ivugwa nka voltage-yo-kwikiza;kuberako ibyanyuma nabyo bibaho kuri voltage nkeya cyane, bikunze kwitwa voltage nkeya yo kwikiza.

Gusezerera Kwikiza

Kugirango ugaragaze uburyo bwo gusohora kwikiza, fata ko hari inenge muri firime ngenga hagati ya electrode ebyiri zicuzwe hamwe na résistance ya R. Ukurikije imiterere yinenge, irashobora kuba inenge yicyuma, icyuma gikoresha igice cyangwa se nabi inenge.Ikigaragara ni uko iyo inenge ari imwe mubyambere, capacitor izaba yasohotse kuri voltage nto.Mu bihe byanyuma niho ibyo bita voltage yamashanyarazi ikiza ubwayo.

Inzira yo gusohora kwikiza ni uko ako kanya nyuma yo gukoresha voltage V kuri capacitori ya firime, icyuma cya ohmic I = V / R kinyura mu nenge.Kubwibyo, ubucucike buriho J = V / Rπr2 butembera muri electrode ya metallize, ni ukuvuga, uko agace kegereye inenge (r ntoya r) kandi nubucucike bwacyo buri muri electrode.Bitewe n'ubushyuhe bwa Joule buterwa no gukoresha ingufu za W = (V2 / R) r, kurwanya R ya semiconductor cyangwa inenge ikingira bigabanuka cyane.Kubwibyo, ikoreshwa rya I hamwe nimbaraga zikoreshwa W ziyongera byihuse, nkigisubizo, ubucucike buriho J1 = J = V / πr12 buzamuka cyane mukarere aho electrode ya metallize yegeranye cyane nubusembwa, kandi ubushyuhe bwayo bwa Joule burashobora gushonga ibyuma. layer mu karere, itera arc hagati ya electrode iguruka hano.Arc ihita yuka kandi ikajugunya icyuma gishongeshejwe, igakora akarere kegeranye kitagira icyuma.Arc yazimye kandi kwikiza kugerwaho.

Bitewe n'ubushyuhe bwa Joule na arc byabyaye mugusohora kwikiza, dielectric ikikije inenge hamwe n’ahantu hitaruye h’ubutaka bwa dielectric byanze bikunze byangizwa n’ubushyuhe bw’amashanyarazi n’amashanyarazi, bityo kubora imiti, gaze na karuboni, ndetse ndetse ibyangiritse birabaho.

Duhereye ku bimaze kuvugwa haruguru, kugira ngo tugere ku buryo bwuzuye bwo kwikiza, birakenewe ko hajyaho ibidukikije bikwiye bikikije inenge, bityo igishushanyo mbonera cy’ibikoresho bya firime ngengabihe bigomba kunozwa kugira ngo bigere ku buryo bwumvikana hafi ya inenge, ubunini bukwiye bwicyuma, ibidukikije bya hermetic, hamwe na voltage nubushobozi bukwiye.Ibyo bita gusohora kwuzuye kwikiza ni: igihe cyo kwikiza ni gito cyane, imbaraga zo kwikiza ni nto, kwigunga neza kwinenge, nta byangiza dielectric ikikije.Kugirango ugere ku kwikiza kwiza, molekile ya firime ngenga igomba kuba irimo igipimo gito cya karubone na atome ya hydrogène hamwe na ogisijeni igereranije, ku buryo iyo kubora kwa molekile ya firime bibaye mugusohora kwikiza, oya karubone ikorwa kandi nta karuboni ibaho kugirango hirindwe inzira nshya ziyobora, ahubwo ni CO2, CO, CH4, C2H2 nizindi myuka ikorwa kugirango izimye arc hamwe no kuzamuka kwinshi kwa gaze.
Kugirango harebwe niba itangazamakuru rikikije inenge ritangirika mugihe cyo kwikiza, imbaraga zo kwikiza ntizigomba kuba nini cyane, ariko kandi ntizibe nto cyane, kugirango ukureho metallisation ikikije inenge, gushiraho insulation. (resistance high) zone, inenge izigunga, kugirango igere ku kwikiza.Ikigaragara ni uko imbaraga zisabwa zo kwikiza zifitanye isano rya bugufi nicyuma cyurwego rwa metallisation, ubunini, nibidukikije.Kubwibyo, kugirango ugabanye imbaraga zo kwikiza no kugera ku kwikiza kwiza, metallisation ya firime organic hamwe nicyuma gike cyo gushonga irakorwa. Byongeye kandi, igipimo cya metallisation ntigomba kuba umubyimba uringaniye kandi unanutse, cyane cyane kugirango wirinde gushushanya, naho ubundi , agace ko kwigunga kazahinduka amashami kandi bikananirwa kugera ku kwikiza kwiza.Imashini za CRE zose zikoresha firime zisanzwe, kandi mugihe kimwe, gucunga neza ibikoresho byinjira byinjira, guhagarika firime zifite inenge kumuryango, kugirango ubwiza bwa firime za capacitor zuzuzwe neza.

Usibye gusohora kwikiza, hariho undi, ariwo mashanyarazi yo kwikiza.Reka tuganire kuri ubu buryo mu ngingo ikurikira.
