Overview

ZW32ABG-12 yekunze yakakwira-voltage inogara magineti vacuum circuit breaker (inozonzi inogara magineti switch) ndeyekunze yakakwira-voltage switchgear ine matatu-phase AC 50Hz uye yakayerwa voltage ye12kV.Iyo yekusingaperi magineti switch inonyanya kushandiswa se 10kV inobuda chinja mune substation uye 10kV matatu-chikamu AC simba system semutsetse yekudzivirira switch yekutsemura uye kubatanidza mutoro wazvino, kutyora kuwandisa kwazvino uye pfupi-yedunhu ikozvino.
Iyo yedunhu inotyora inoenderana nehunyanzvi zviyero zvakaita seGB1984-2003 "High Voltage AC Circuit Breaker", DL/T402-2007 "High Voltage AC Circuit Breaker Ordering Technical Conditions" uye DL/T403-2000 "12kV-40.5 Vacuit High Voltage Voltage". Breaker Ordering Technical Conditions”.

Normal Kushandisa Conditions

◆ Ambient tembiricha: -40℃~+40℃;Altitude: 2000m uye pasi;
◆ Mhepo yakapoteredza inogona kusvibiswa neguruva, utsi, gasi rinoparadza, mhute kana mhute yemunyu, uye chiyero chekusvibiswa ndicho chinhanho chinotarirwa;
◆Kumhanya kwemhepo hakupfuuri 34m/s (yakaenzana ne700Pa pane cylindrical surface);
◆ Mamiriro chaiwo ekushandiswa: Muchengeti wedunhu anogona kushandiswa pasi pemamiriro ezvinhu akasiyana neaya ataurwa pamusoro apa.Ndapota taurirana nesu kune zvakakosha zvinodiwa.
