Ugereranije nubundi buryo bwo gutandukanya ibintu, ihame ryumuzunguruko wa vacuum riratandukanye niry'ibintu bya rukuruzi. Nta dielectric iri mu cyuho, ituma arc kuzimya vuba. Rero, imbaraga kandi zihamye zamakuru zamakuru zo guhuza ibintu ntizitandukanijwe cyane. Guhindura akato muri rusange bikoreshwa mubikoresho byingufu zamashanyarazi mugutunganya inganda zifite voltage nkeya ugereranije! Hamwe niterambere ryihuse rya sisitemu yo gutanga amashanyarazi, 10kV yamashanyarazi yamashanyarazi yakozwe cyane kandi ikoreshwa mubushinwa. Kubakozi bashinzwe kubungabunga, bimaze kuba ikibazo cyihutirwa kunoza ubuhanga bwimyuka yamashanyarazi, gushimangira kubungabunga, no gukora neza kandi byizewe. Dufashe ZW27-12 nk'urugero, impapuro zerekana muri make ihame shingiro no gufata neza icyuma cyangiza.
1. Ibikoresho byo kubika ibintu.
Vacuum ifite imiterere ikomeye. Muri vacuum yamashanyarazi, imyuka iroroshye cyane, kandi gahunda yo gutera inkoni uko bishakiye imiterere ya molekile yumwuka ni nini cyane, kandi amahirwe yo kugongana ni nto. Kubwibyo rero, ingaruka zidasanzwe ntabwo arimpamvu nyamukuru yo kwinjira mu cyuho cya vacuum, ariko bitewe ningaruka zikomeye zumuriro wa electrostatike, ibyuma bya electrode byashyizwe mubintu byibyuma nibintu byingenzi byangiza.
Imbaraga zo guhunika dielectric mu cyuho cya vacuum ntabwo zifitanye isano gusa nubunini bwikinyuranyo nuburinganire bwumurima wa electromagnetique, ariko kandi bigira ingaruka cyane kubiranga electrode yicyuma hamwe nuburinganire bwubutaka. Ku ntera ntoya (2-3mm), icyuho cya vacuum gifite imitekerereze ya gaze yumuvuduko ukabije wa gaze na gaze ya SF6, niyo mpamvu aho uhurira hafunguye intera yameneka ya vacuum muri rusange ari nto.
Ingaruka itaziguye ya electrode yicyuma kumashanyarazi yamenetse igaragarira cyane cyane mubukomere (imbaraga zo kwikuramo) yibikoresho fatizo hamwe no gushonga kwibikoresho. Iyo imbaraga zo guhonyora hamwe no gushonga, niko imbaraga za dielectric compressive imbaraga zicyiciro cyamashanyarazi munsi ya vacuum.
Ubushakashatsi bwerekana ko uko agaciro ka vacuum kari hejuru, niko hejuru ya voltage yameneka ya gaze ya gaze, ariko ahanini ntigihinduka hejuru ya 10-4 Torr. Kubwibyo, kugirango ubungabunge neza imbaraga zo kwikuramo imbaraga za vacuum magnetique zihumeka, impamyabumenyi ya vacuum ntigomba kuba munsi ya 10-4 Torr.
2. Gushiraho no kuzimya arc mu cyuho.
Vacuum arc iratandukanye cyane nuburyo bwo kwishyuza no gusohora imyuka arc wize mbere. Imiterere idasanzwe yumuyaga ntabwo aribintu byambere bitera arcing. Vacuum arc kwishyuza no gusohora bibyara mumyuka yibikoresho byibyuma bihindagurika mukora kuri electrode. Mugihe kimwe, ingano yimena yamashanyarazi nibiranga arc nabyo biratandukanye. Mubisanzwe tuyigabanyamo ibice bike-vacuum arc hamwe na vacuum-nini cyane.
1. Umwanya muto wa vacuum arc.
Iyo aho uhurira hafunguwe mu cyuho, bizatera ibara rya electrode itari nziza aho ingufu za kinetic na kinetic ziba zegeranye cyane, kandi imyuka myinshi yibikoresho byumuyaga bizahinduka biturutse kumabara mabi ya electrode. yakongejwe. Muri icyo gihe, ibyuma byumuyaga hamwe nuduce twa mashanyarazi mu nkingi ya arc bikomeje gukwirakwira, kandi icyiciro cyamashanyarazi nacyo gikomeza guhindagurika ibice bishya kugirango byuzure. Iyo ikigezweho kirenze zeru, imbaraga za kinetic ya arc ziragabanuka, ubushyuhe bwa electrode buragabanuka, ingaruka nyazo za volatilisation ziragabanuka, nubucucike bwimbaraga mu nkingi ya arc buragabanuka. Hanyuma, ikibanza cyiza cya electrode kiragabanuka kandi arc irazima.
Rimwe na rimwe, guhindagurika ntibishobora kugumana igipimo cyo gukwirakwiza inkingi ya arc, kandi arc irazima gitunguranye, bikavamo umutego.
