Itandukaniro riri hagati yaicyuma gifata zinc oxydenaagakoresho ko gufata inkokora
1. (1) Ihame ry'imikorere y'icyuma gifata ubwoko bwa valve:
Iyo sisitemu isanzwe, icyuho cy'ingufu gitandukanya uburinzi bwa plaque ya valve na bisi ikora, kugira ngo idatwika uburinzi bwa plaque ya valve bitewe n'umuvuduko w'amashanyarazi uterwa no uburinzi bwa plaque ya valve n'imbaraga z'amashanyarazi.
Iyo voltage iri kuri bisi ikora irenze agaciro kayo ka volteji yo kwangirika, icyuho cy'urumuri kizacikamo ibice maze bigatuma umuriro w'inkuba winjira mu butaka unyuze mu budahangarwa bwa valve plate. Muri iki gihe, agaciro k'ubudahangarwa bwa valve plate buzagabanuka mu buryo bwikora kugira ngo budahangarwa bugabanuke ku mpera zayo zombi. Umuvuduko usigaye waravutse.
Nyuma y’uko umuriro w’inkuba ubuze, voltage ikora ku bushyuhe bwa valve plate ni voltage ya frequency y’ingufu. Muri iki gihe, agaciro k’ubushyuhe bwa valve plate kaziyongera mu buryo bwikora, bigabanye frequency y’ingufu kugira ngo arc izime vuba kandi neza.
(2) Igikoresho cyo gufata valve kigizwe n'icyuho kinini cy'ingufu n'ibirwanya plaque za valve bikurikiranye.
Intera iri hagati y'icyuho cy'urumuri ni nto, ingufu z'amashanyarazi zisa n'iz'amashanyarazi zisanzwe, imiterere ya volt-second ni ndende, kandi guhuza ingufu z'amashanyarazi biroroshye kubibona. Byongeye kandi, icyuho kinini gituma ingufu z'amashanyarazi zigabanywamo ibice iyo ingufu zikomeje gutemba. Ugereranyije n'inkingi ndende, icyuho kigufi cyoroshye kugikata, kandi ubushobozi bwo kugarura imbaraga z'amashanyarazi z'icyuho burushaho kwiyongera.
Kuba hariho uburyo bwo kwirinda kwa valve plate birinda imiraba igabanya ubushyuhe idashobora gukurura insulation. Kudahuza kwayo bituma igaragaza ubushobozi bwo kwirinda bwa hato iyo inyura ku murasire w'amashanyarazi kugira ngo igabanye ingufu zisigaye za arrester kandi irusheho kunoza imikorere yo kurinda; iyo inyura ku murasire w'amashanyarazi, igaragaza ubushobozi bwo kwirinda bwa hato na hato kandi ingufu za hato na hato zihoraho kugira ngo igabanye imbaraga za hato na hato kandi irusheho kunoza imikorere yo kuzimya arc.
2. (1) Ihame ry'imikorere y'icyuma gifata zinc oxide:
Mu gihe cy'imikorere y'amashanyarazi, umuriro unyura muri valve ya ZnO uba uri munsi cyane ya 1mA (igice cy'ingenzi ni umuriro ukoresha ingufu), uhwanye n'icyuma gikingira kandi ntuzatwika valve, bityo voltage ikora ishobora gukurwaho nta cyuho kirimo.
Iyo voltage ikoreshejwe kuri valve ya ZnO irenze agaciro runaka (voltage y'imikorere ya mbere U1mA), "on" irabaho. Nyuma ya "on", resistance ya valve ya ZnO iba nto cyane, kandi voltage isigaye ifitanye isano n'umuyoboro w'amashanyarazi unyuramo. Mu by'ukuri ntaho bihuriye.
Iyo voltage ikoreshejwe igabanutse munsi y'voltage ikora, "on" ya plate ya valve ya ZnO irahagarara, bingana n'icyuma gikingira, bityo nta frequency y'amashanyarazi ibaho.
Iyi niyo mpamvu MOA ishobora kugera ku muvuduko udatemba nta guhindagurika kw'amashanyarazi. (Umuriro w'amashanyarazi wabaye insulator mu bihe byashize, bityo umuriro w'amashanyarazi ni wo wonyine unyura muri plaque ya valve ya ZnO)
Ugereranyije na valve za silicon carbide SiC, valve za ZnO zifite imiterere myiza ya volt-ampere idashingiye ku murongo.
(2) Ugereranyije n'icyuma gisanzwe gifata ibintu kigizwe na disiki ya valve ya SiC n'uruhererekane rw'icyuho, icyuma gifata ibintu kidafite icyuho cya zinc oxide gifite ibyiza bikurikira:
①Imiterere yoroshye, ikwiriye gukorwa mu buryo bunini, ni nto, ifite uburemere bworoheje kandi ihendutse.
② Uburinzi buhanitse cyane. Kubera ko valve ya ZnO ifite imiterere myiza ya volt-ampere, voltage isigaye iba iri hasi; ishobora kurekura ingufu mu gihe cyose cy’ingufu nyinshi, kandi nta kirabyo, bityo nta gutinda gusohora, kandi ifite imiterere myiza yo gusubiza umuraba mwinshi, cyane cyane ikwiriye kurinda GIS substations zirinda gazi na sisitemu za DC.
③Ubushobozi bukomeye bwo kwihanganira ibikorwa bisubirwamo, ifata gusa ingufu zirenze urugero, nta mpamvu yo gufata ingufu zikoresha imbaraga zidasanzwe.
④Ubushobozi bunini bwo gutemba. Ubushobozi bwo gutemba kuri buri gice cy'agace ka valve ya ZnO ni inshuro 4 kugeza kuri 5 z'agace ka valve ya SiC. Ishobora gukoreshwa nk'uburinzi bw'inyongera ku bushyuhe bw'imbere.
⑤Kurwanya ibara neza. Kubera ko nta cyuho kiri mu mfuruka, ikibazo cy'ingufu zidahindagurika zo gusohora icyuho cy'imfuruka bitewe n'umwanda utaringaniye ku buso bw'icyuma cya porcelain gishobora kwirindwa, kandi biroroshye gukora ibikoresho bigabanya umwanda no gusukura neza. (Nta ngaruka zatewe n'umwanda uri ku buso)
