12 17.5 24kV Indoor Vacuum Circuit Breakers, GPVN-E Series

Incazelo emfushane:

I-GPVN-12kV/17.5Kv/24kV Model yasendlini ye-AC high voltage vacuum circuit breaker iwuhlobo lwe-switchgear ephezulu futhi evalwe ngokuphelele, inobukhulu obuhlangene kanye nevolumu encane.I-VCB isebenza kusistimu yamandla kagesi olinganiselwe ongu-7.2~24kV, izigaba ezintathu kanye ne-AC 50/60Hz.Kusebenza ezikhathini lapho kusebenza khona njalo, kusebenza ukuze kuvikelwe futhi kulawule intambo kanye nemishini kagesi.Umkhiqizo uhambisana ne-IEC62271-100, GB1984, JB3855 kanye ne-DL1403 futhi uphumelele ukuhlolwa kohlobo.
