Ubushinwa VD4 bukurikirana vacuum circuit-breakers ni ibikoresho byo kwishyiriraho ibikoresho byo mu nzu.Nyamuneka saba ROCKWILL kubisabwa bidasanzwe byo kwishyiriraho.VD4-R ikurikirana ya voltage iciriritse yamashanyarazi yamashanyarazi hamwe nuburyo bukoreshwa muburyo bwo kwishyiriraho imbere biranga tekinike yo kubaka inkingi.Buri nkingi ibamo icyuho cyahagaritswe muri resin iyo silinderi ibumbwe bitewe nuburyo budasanzwe bwo gukora.Ubu buryo bwubwubatsi burinda icyuho cya vacuum guhungabana, umwanda hamwe na kondegene.
VCB VS1 12kV 630A Imbere mu nzu Umuvuduko mwinshi wa Vacuum Umuzunguruko:
Intera intera: 210mm
Ubwoko bw'intoki
Uburyo bubiri bwo gukora amasoko
Ahantu hashobora gukoreshwa: (cyane cyane ahantu hakenewe ibikorwa kenshi)
1.ibikoresho byamashanyarazi kugenzura no kurinda inganda.
2.ubucukuzi bw'amabuye y'agaciro.
3.ibimera.
4.ububiko.
Irashobora gukosorwa muri kabine ya switch cyangwa igashyirwa kumaboko.
Imikorere ihamye no kwishyiriraho byoroshye.
Ibyuka byumuzunguruko
1. Imiterere yoroshye.
2.Koresha ultra nkeya yo kurwanya ubwoko bwa vacuum interrupter.
3.Koresha uburyo bwiza kandi bukoreshwa muburyo bwimikorere.
4.Bikwiriye ibihe hamwe nibikorwa kenshi.
5.Kubungabunga neza nubuzima bwa serivisi ndende.
6.Imikorere yizewe.
Ibidukikije
Ubushyuhe bw’ibidukikije: - 40 ° C ~ + 40 ° C (munsi ya 35 ° C mu masaha 24)
Ubushuhe bugereranije: ≤95% (impuzandengo ya buri munsi) cyangwa ≤ 90% (impuzandengo ya buri kwezi)
Uburebure: m 1000m
