Overview

ZW32-12 (G) yekunze vacuum circuit breaker (inozodaidzwa kuti circuit breaker) mudziyo wekunze wekugovera magetsi une rated voltage ye12kV uye matatu-phase AC 50Hz.
Inonyanya kushandiswa kutyora uye kuvhara mutoro wezvino, kuwedzeredza ikozvino uye pfupi-yedunhu ikozvino musimba remagetsi.Inokodzera kuchengetedzwa uye kutonga mune zviteshi uye masimba ekugovera masisitimu emaindasitiri uye emigodhi mabhizinesi, uye nzvimbo dzinoshanda magridi emagetsi ekumaruwa.
Iyo yedunhu inotyora ine hunhu hwehukuru hudiki, huremu huremu, anti-condensation, kuchengetedza-isina, nezvimwewo, uye inogona kuchinjika kune yakaoma mamiriro ekunze uye nharaunda dzine tsvina.

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.
