Impamvu n'ibiranga umuvuduko mwinshi wo guturika kwikirahure

1 mechanism Uburyo bwo guturika bwikirahure

Ikirahure cyikirahure ni ikirahure kirangwa, kirangwa no guhagarika umutima hejuru no guhangayika imbere, nkuko bigaragara ku gishushanyo.

Shimangira ibyiciro byikirahure

Guhangayikishwa nikirahuri biterwa nihinduka ryubushyuhe mugutunganya ibirahure.Iyo ikirahuri cyashyutswe kugirango ubushyuhe bworoshe (760 ~ 780 ℃) bukonje vuba, imbaraga zo kuzimya urwego rwo hejuru ziragabanuka, ariko ubushyuhe bwimbere buracyari hejuru kandi buri muburyo bwo kwaguka, bikaviramo guhagarika kugabanuka. cy'ubuso bw'ubuso hamwe no guhagarika umutima muburyo bwo hejuru;Noneho ubushyuhe bwimbere buragabanuka kandi butangira kugabanuka, ariko muriki gihe, urwego rwo hejuru rwarushijeho gukomera, bivamo kugabanuka imbere imbere no guhagarika umutima.Ubu bwoko bubiri bwimyitwarire bukwirakwizwa kimwe mubirahure kugeza bikonje rwose kandi ubushyuhe bwikigereranyo burashira, ibyo bikaba ari impagarara zihoraho.

Iyo uburinganire buri hagati yumuvuduko ukabije wumuvuduko ukabije hamwe nigihagararo cyikirahure cyikirahure cyikirahure kirangiritse, ibice bizahita byihuta bitewe nigikorwa cyo guhangayika, bizatera kumenagura ibirahuri, ni ukuvuga guturika.

2 uses Impamvu n'ibiranga guturika wenyine

Impamvu zitera ibirahuri byizana birashobora kugabanywamo ibyiciro bibiri: ubuziranenge bwibicuruzwa nibidukikije bikora.Mubihe bifatika, akenshi hariho impamvu ebyiri icyarimwe.

a.Impamvu zubwiza bwibicuruzwa

Impamvu nyamukuru nuko hariho ibice byanduye imbere yikirahure, kandi ibisanzwe ni nis ibice.Icyiciro cyinzibacyuho ya NIS murwego rwo gushonga ibirahuri hamwe na annealing ntabwo byuzuye.Iyo insulator imaze gushyirwa mubikorwa, bifatwa ko icyiciro cyo guhinduka no kwaguka bibaho gahoro gahoro, bikavamo gucika mubirahure.Iyo diameter yimyanda irenze agaciro runaka, ntishobora gukurwaho nubukonje nubushyuhe bukabije, bikavamo umuvuduko mwinshi wo guturika kwi insulirateri ukora Hongping].Iyo ibice byanduye biri mubice byimbere byikirahure cyikirahure, birashoboka ko umuntu yaturika wenyine.Kuberako ikirahuri ubwacyo ari ibintu byoroshye, birwanya umuvuduko ariko ntibikaze, ibyinshi kumeneka kwikirahuri biterwa no guhangayika.

ibiranga:

Kwiyiturika kwonyine guterwa nuduce twanduye twimbere ni hejuru yimyaka itatu mbere yo gukora, kandi bizagenda bigabanuka nyuma yaho, iryo rikaba ari itegeko ryingenzi ryo gucira urubanza icyateye.

B) ibisasu byonyine bishobora guturika kumwanya utandukanye wumugozi wa insulator ni kimwe;

b.Impamvu zituruka hanze

Ahanini umwanda nubushyuhe butandukanye.Mubikorwa icyarimwe cyo kwegeranya umwanda, ubushuhe hamwe numurima wamashanyarazi, imiyoboro yamenetse hejuru ya insulator ni nini cyane, bikavamo igice cyumukandara wumye.Iyo ihungabana ryumwuka ribaye kumukandara wumye, arc yabyaye izangirika ijipo yikirahure, kandi iyo ubujyakuzimu bwimbitse bwimbitse, bizatera guturika.Niba insulator ikubiswe numurabyo mugihe cyavuzwe haruguru, amahirwe yo guturika kwizana ryikirahure cyangiritse na arc biziyongera cyane.Gukora nabi cyane ni urufunguzo, rushobora guterwa nubucucike bwumunyu mwinshi cyangwa uduce twinshi twifu yifu mubyuma.

ibiranga:

A) birashoboka ko guturika kwonyine kutagaragara mumyaka mike yambere ikora, ariko bibaho cyane mugihe runaka nyuma yimyaka myinshi ikora (impinduka zikomeye mumasoko y’umwanda zitera umwanda ukabije);

B) ubwisanzure bwo guturika birashoboka ko amaherezo ya voltage arangiye hamwe na voltage ntoya yumurongo wa insulator iruta iyo hagati (umurima wamashanyarazi kumpera yumuriro mwinshi hamwe numuhengeri muke urakomeye, kandi creepage yaho ibaho ubanza kumaguru yicyuma cya insulator mugihe umwanda uremereye);

C) ukuguru kwicyuma cya insulatrice idaturika yonyine muminara imwe yarangiritse (arc yaho iterwa no kwirundanya kwinshi kwangiza kwangiza ikirahure hafi yamaguru yicyuma), kandi hari uduce twiza hejuru yumutaka;

Kwangirika kwikirahure hafi yikirenge

3 analysis Gusesengura inyundo zisigaye

Nyuma yo guturika kwizengurutsa ibirahure byikirahure, ikirahuri cya disikuru yamenetse kandi kiratatana kugirango kibe inyundo isigaye.Imiterere yikirahure ku nyundo isigaye irashobora gutanga ubufasha bwo gusesengura icyateye kwiyahura.Imiterere n'ubwoko bw'ikirahuri gisigaye:

a.Imirasire

Kubiturika ubwabyo biterwa nubusembwa bumwe, aho gutangirira ushobora kuboneka mugushakisha inyuma.Niba ikirahure kimenetse ku nyundo isigaye iri mumiterere ya radio, aho itangirira, ni ukuvuga aho itangirira kwiyahura, iherereye kumutwe wikirahure.Muri iki gihe, guturika kwonyine guterwa nubwiza bwikirahure ubwacyo, nko gukubita, inzira yo gusesa, nibindi.

Inyundo isigaye

b.Amafi

Niba ikirahure kimenetse ku nyundo gisigaye kiri mumiterere yumunzani wamafi, kandi aho gutangirira kwiyahura biri hafi yikigice cyikirahure hafi yumutwe wicyuma, hari impamvu ebyiri zishobora gutera kwiyahura muriki kibazo, ko ni, ikirahure kimenetse kubera guturika kwonyine kwibicuruzwa byangiritse cyangwa imbaraga zo hanze, bishobora kuba impagarara zumukanishi cyangwa guhangayikishwa n amashanyarazi, nko guhora gukubita amashanyarazi, kumenagura ibice byibirahuri biterwa numurongo munini w'amashanyarazi nini kandi idatemba. ikigezweho, n'ibindi.

Igipimo cy'amafi asigaye

c.Bivanze

Niba ikirahure kimenetse ku nyundo gisigaye kibaho haba mubipimo byamafi ndetse no muburyo buteganijwe, aho gutangirira kwiyahura biherereye kumutwe wumutaka wikirahure.Muri iki gihe, guturika kwonyine bishobora guterwa nimpamvu zimbere ninyuma.

Inyundo isigaye ivanze ubwoko

4 、 Kurwanya ingamba

a.Igenzura ryinjira: ubwiza bwibikoresho byogukoresha ibirahuri bigenzurwa hifashishijwe igenzura ryerekana ibyangiritse no gukora ingaruka zikomeye.

b.Imashini ikomatanya ikoreshwa ahantu handuye cyane.Niba hemejwe ko guturika kwonyine guterwa no kwirundanya kwinshi, insulator zikoreshwa zishobora gusimbuza insulator.

c.Shimangira ubugenzuzi bw'irondo, kandi ukore irondo ryihariye kumurongo wogukwirakwiza mugihe cyikirere kibi nko gukubita inkuba.

d.Witondere ubwikorezi.Mugihe cyo kubaka ibikorwa remezo no gusana byihutirwa, insulirasi yikirahure ikingiwe igomba gukingirwa nibintu birinda kugirango birinde kwangirika.

Kugeza ubu, kugenzura ubuziranenge bw’ikirahure mu nganda nini zo mu gihugu ni byiza, kandi ntibikiri ngombwa gukoresha insulator zikirahure zavuzwe kera nyuma yo guhagarara igice cyumwaka.
