Overview

ZW8-12 yekunze yakakwira-voltage vacuum circuit breaker, matatu-phase AC 50Hz yekunze yakakwira-voltage switchgear.Iyo inoumbwa nekushanda, conductive wedunhu, insulation system, chisimbiso uye goko, uye iyo yakazara chimiro ndeye matatu-chikamu chakajairika bhokisi mhando.Inoshandiswa kune 10kV yekumaruwa magetsi gidhi uye emaguta emagetsi gidhi system, sekupatsanurwa, kusanganisa mutoro wazvino, wakawandisa wazvino, pfupi-dunhu razvino uye dzimwe nzvimbo dzakafanana.
Shandisa yakajairwa GB1984-2003 "High Voltage AC Circuit Breaker" GB/T11022-1999 "Common Technical Requirements for High Voltage Switchgear uye Control Equipment Standards" IEC62271-100 "High Voltage AC Circuit Breaker"

Normal Kushandisa Conditions

◆ Ambient tembiricha: -40℃~+40℃;
◆ Altitude: ≤3000m (kana kukwirira kunowedzera, chiyero chekudzivirira chinopisa chichawedzera maererano);
◆ Mhepo yakapoteredza inogona kusvibiswa neguruva, utsi, gasi rinoparadza, steam kana salt spray, uye kusvibiswa kwemazinga iIV;
◆Kumhanya kwemhepo hakupfuuri 34m/s (yakaenzana ne700Pa pane cylindrical surface);
◆Vibration kana kufamba kwepasi kubva kunze kwe switchgear uye midziyo yekudzora inogona kuregererwa;
◆Mamiriro chaiwo ekushandiswa.(Kana iwe uchida kuishandisa pasi pezvakajairwa mamiriro ekushandiswa akasiyana neari pamusoro, ndapota taurirana nesu).
