Isifinyezo
Imikhiqizo yethu emisha, i-NVS1-12 series vacuum vacuum breaker yasendlini isetshenziselwa ama-switchgears ohlelweni lwamandla angu-12kV, njengeyunithi yokulawula nokuvikela impahla kagesi emabhizinisini ezimboni nezimayini, izitshalo zikagesi neziteshi ezincane. Ngenxa yezinzuzo ezikhethekile ze-vacuum circuit breaker, ifaneleka ngokukhethekile ukusebenza okuvamisile okudinga isilinganiso samanje sokusebenza, noma izindawo lapho i-short-circuit current iphulwa izikhathi eziningi. I-circuit breaker yamukela umklamo ohlanganisiwe wendlela yokusebenza kanye nomzimba we-circuit breaker. Zombili ziyisakhiwo sangaphambili nangemuva, esinomsebenzi othembekile wokuxhumanisa. I-circuit breaker ingasetshenziswa njengeyunithi yokufaka engaguquki. Ingase futhi ifakwe iloli lika-chassis ibe iyunithi yenqola yesandla.
Izindinganiso zomkhiqizo
I-GB/T1984-2014 I-voltage ephezulu ye-AC Circuit Breaker
I-JB/T3855-2008 3.6-40.5kV yasendlini i-AC High voltage vacuum circuit breaker
