Imiterere, ihame nibiranga vacuum yamashanyarazi

Imiterere ya vacuum yamashanyarazi
Imiterere ya vacuum yamashanyarazi igizwe ahanini nibice bitatu: vacuum arc kuzimya icyumba, uburyo bwo gukora, inkunga nibindi bice.

1. Guhagarika icyuho
Vacuum interrupter, izwi kandi nka vacuum switch tube, nigice cyibanze cyumuzunguruko.Igikorwa cyacyo nyamukuru ni ugushoboza umuzunguruko uciriritse kandi mwinshi kugirango uzimye vuba arc no guhagarika amashanyarazi nyuma yo guhagarika amashanyarazi binyuze mumikorere myiza yo gukingira icyuho mumiyoboro, kugirango wirinde impanuka nimpanuka.Vacuum interrupters igabanijwemo ibirahuri vacuum interrupters na ceramic vacuum interrupters ukurikije ibishishwa byabo.

Icyumba kizimya Vacuum arc kigizwe ahanini nigikonoshwa cyumuyaga gikonje cyane, umuzenguruko uyobora, sisitemu yo gukingira, guhuza, inzogera nibindi bice.

1) Sisitemu yo gukumira ikirere
Sisitemu yo guhumeka ikirere igizwe nigikonoshwa cyo mu kirere gikozwe mu kirahure cyangwa mu bukerarugendo, isahani yimuka yimuka, isahani ihamye, hamwe n’ibyuma bidafite ingese.Kugirango hamenyekane neza umwuka mwiza hagati yikirahure, ububumbyi nicyuma, usibye uburyo bukomeye bwo gukora mugihe cyo gufunga, ubwikorezi bwibikoresho ubwabwo burasabwa kuba buto bushoboka kandi irekurwa ryimbere ryimbere rigarukira byibuze.Ibyuma bitagira umuyonga ntibishobora gutandukanya gusa icyuho kiri imbere mu cyumba kizimya icyuma cya vacuum arc kiva mu kirere cyo hanze y’ikirere, ariko kandi gishobora gutuma imikoranire yimuka hamwe ninkoni yimuka igenda mu ntera yagenwe kugirango irangize ibikorwa byo guhuza no guhagarika imikorere ya vacuum.

2) Sisitemu yo kuyobora
Sisitemu yo kuyobora icyumba kizimya arc igizwe ninkoni ihamye yo kuyobora, hejuru yimikorere ya arc igaragara, guhuza bihamye, guhuza kwimuka, kugenda hejuru yimigozi yimbere hamwe ninkoni ikora.Muri byo, inkoni ihamye yo kuyobora, igendagenda hejuru ya arc hejuru hamwe nu guhuza bihamye hamwe hamwe bita electrode ihamye;Kwimura guhuza, kwimuka arc hejuru hamwe no kugenda inkoni iyobora hamwe hamwe nka electrode igenda.Iyo icyuma cyumuzunguruko cya vacuum, icyuma cyumuvuduko wa vacuum hamwe numuyoboro wa vacuum uteranijwe nicyumba kizimya vacuum arc gifunze, uburyo bwo gukora bufunga imikoranire yombi binyuze mukugenda kwinkoni yimuka, bikarangiza guhuza umuzunguruko.Kugirango ukomeze guhuza imikoranire hagati yimibonano yombi ntoya ishoboka kandi itajegajega, kandi ifite imbaraga zumukanishi mugihe icyumba kizimya arc gifite imbaraga zihamye zumuvuduko, icyuma cya vacuum gifite icyuma kiyobora kuruhande rumwe rwimikorere ya dinamike. inkoni, hamwe nuruhererekane rwo guhonyora amasoko akoreshwa kugirango agumane umuvuduko uringaniye hagati yabahuza bombi.Iyo icyuho cya vacuum kimennye ikigezweho, imikoranire ibiri yicyumba kizimya arc itandukanya kandi ikabyara arc hagati yabo kugeza igihe arc izasohokera mugihe isanzwe isanzwe irenga zeru, kandi kumeneka kwinzira birangiye.

3) Sisitemu yo gukingira
Sisitemu yo gukingira icyumba kizimya vacuum igizwe ahanini na silinderi ikingira, igipfukisho gikingira nibindi bice.Imikorere nyamukuru ya sisitemu yo gukingira ni:

(3) Gukuramo igice cyingufu za arc nibicuruzwa bya arc.Cyane cyane iyo guhagarika icyuho bihagarika umuyoboro mugari muto, ingufu nyinshi zubushyuhe zitangwa na arc zinjizwa na sisitemu yo gukingira, ifasha kunoza imbaraga zo kugarura dielectric hagati yabahuza.Umubare munini wibicuruzwa bya arc byinjizwa na sisitemu yo gukingira, niko imbaraga ziyikuramo, bigira uruhare runini mu kongera ubushobozi bwo kumeneka kwa vacuum.

4) Sisitemu yo kuvugana
Guhuza nigice aho arc ikorerwa kandi ikazimya, kandi ibisabwa kubikoresho nuburyo biri hejuru.
(1) Ibikoresho
Hano haribisabwa bikurikira kubikoresho byitumanaho:
a.Ubushobozi bwo kumena cyane
Irasaba ko ubwikorezi bwibikoresho ubwabwo ari bunini, coefficente yubushyuhe bwumuriro ni nto, ubushobozi bwumuriro ni bunini, nubushobozi bwo kohereza ibyuka bya elegitoronike ni buke.
b.Umuvuduko mwinshi wo kumeneka
Umuvuduko mwinshi wa voltage uganisha kuri dielectric imbaraga zo kugarura imbaraga, zifasha kuzimya arc.
c.Kurwanya amashanyarazi menshi
Ni ukuvuga, irashobora kwihanganira gukuraho arc amashanyarazi kandi ikagira ibyuma bike.
d.Kurwanya gusudira.
e.Agaciro gake gaciriritse gasabwa kuba munsi ya 2.5A.
f.Ibirimo gaze nkeya
Umwuka muke nicyo gisabwa kubikoresho byose bikoreshwa imbere ya vacuum.Umuringa, byumwihariko, ugomba kuba umuringa wubusa wa ogisijeni uvuwe nuburyo budasanzwe burimo gaze nke.Kandi amavuta ya feza n'umuringa birakenewe kubagurisha.
g.Ibikoresho byo guhuza icyumba cyo kuzimya vacuum arc kumashanyarazi yamashanyarazi ahanini bifata umuringa wa chromium, hamwe numuringa na chromium bingana na 50%.Urupapuro rw'umuringa rwa chromium ruvanze n'ubugari bwa 3mm rusudwa hejuru yubusabane bwo hejuru no hepfo.Ibisigaye byitwa contact base, bishobora gukorwa mumuringa wubusa wa ogisijeni.

(2) Imiterere y'itumanaho
Imiterere yo guhuza ifite uruhare runini kumena ubushobozi bwa arc kuzimya icyumba.Ingaruka yo kuzimya arc yakozwe mugukoresha imibonano nuburyo butandukanye iratandukanye.Hariho ubwoko butatu bwibisanzwe bikoreshwa: guhuza imitambiko yubwoko bwimiterere ihuza, guhuza imiterere yikombe guhuza na chute hamwe nigikombe kimeze nkigikonoshwa hamwe na magnetique ya magnetique, murwego rwikibumbano kimeze nkigikombe gihuza na magnetiki ya magnetique nicyo cyingenzi.

5) Inzogera
Inzogera ya kizimyamwoto ya vacuum arc ishinzwe cyane cyane kugenzura urujya n'uruza rwa electrode igenda murwego runaka no gukomeza icyuho kinini mugihe kirekire, kandi ikoreshwa kugirango icyumba kizimya vacuum arc gifite ubuzima bukomeye bwubukanishi.Inzogera ya vacuum interrupter ni ikintu cyometseho uruzitiro rukozwe mubyuma bidafite ingese hamwe nubunini bwa 0.1 ~ 0.2mm.Mugihe cyo gufungura no gufunga inzira ya vacuum, inzogera zicyumba kizimya arc zishobora kwaguka no kugabanuka, kandi igice cyinzogera kirahangayikishwa nimpinduka zitandukanye, bityo ubuzima bwumurimo bwinzogera bugomba kugenwa ukurikije kwaguka kenshi no kugabanuka hamwe nigitutu cya serivisi.Ubuzima bwa serivisi bwinzogera bujyanye nubushyuhe bwubushyuhe bwakazi.Nyuma yo kuzimya icyumba cya vacuum arc kumenagura umuyoboro mugari muto, ubushyuhe busigaye bwinkoni yayobora bwimurirwa mu nzogera kugirango ubushyuhe bwikariso.Iyo ubushyuhe buzamutse kurwego runaka, bizatera umunaniro w inzogera kandi bigire ingaruka kumurimo wa serivise.
