Ugereranije nizindi zimena imizunguruko, ihame ryakazi rya vacuum circuit breaker iratandukanye niyizimya arc.Nta buryo bwo kuyobora bukoreshwa muri vacuum, butuma arc kuzimya vuba.Kubwibyo, intera iri hagati yingirakamaro na static ihuza imiyoboro yamashanyarazi ni nto cyane.
Ibiranga insulasiyo
Vacuum ifite ibimenyetso bikomeye byo gukumira.Muri vacuum yamashanyarazi, gaze iroroshye cyane, ingendo yubusa ya molekile ya gaze ni nini cyane, kandi amahirwe yo kugongana ni nto cyane.Kubwibyo, kugongana gutandukana ntabwo arimpamvu nyamukuru yo gutandukana kwimyanya yumwanya nyawo, ariko ibice byicyuma bigwa na electrode munsi yumuriro wumuriro w'amashanyarazi ufite imbaraga nyinshi nibyo bintu nyamukuru byangiza kwangirika.
Imbaraga zo gukumira mu cyuho ntizijyanye gusa nubunini bwikinyuranyo hamwe nuburinganire bwumuriro wamashanyarazi, ariko kandi bigira ingaruka cyane kumiterere yibikoresho bya electrode hamwe nubuso bwubuso.Ukurikije intera ntoya (2-3 mm), icyuho cya vacuum gifite ibimenyetso biranga izirinda umuyaga mwinshi hamwe na gaze ya SF6, niyo mpanvu ituma intera yo gufungura imiyoboro yameneka ya vacuum muri rusange ari nto.
Ingaruka yibikoresho bya electrode kumashanyarazi yamenetse bigaragarira cyane cyane mumashanyarazi (imbaraga za tensile) yibikoresho hamwe no gushonga kwibikoresho byicyuma.Iyo imbaraga zingana ningingo zishonga, niko imbaraga zokwirinda za electrode munsi ya vacuum.
ihame ry'akazi
Iyo umuyaga mwinshi wa vacuum unyuze muri zeru, plasma iratandukana vuba kandi ikazimya arc kugirango irangize intego yo guca umuyaga.
