LW3-10 Sab Nraum Tshaj Tawm High Voltage SF6 Circuit Breaker
SF6 roj yog qhov zoo insulating thiab arc-extinguishing nruab nrab, thiab nws muaj kev ua tau zoo tshaj plaws. Cov cuab yeej zoo li no yog kev tsim kho thoob plaws ntiaj teb.
LW3-10 I II III hom sab nraum zoov SF6 Circuit Court tej fais fab saws SF6 roj raws li qhov rov tua thiab qhov nruab nrab, uas yog siv rau tus kheej tig arc extinguishing txoj kev xav kev ua haujlwm ua haujlwm tau muab faib ua I hom tes them lub caij nplooj hlav kev ua haujlwm, II hom lub cev muaj zog them rau lub caij nplooj ntoo hlav. kev khiav hauj lwm mechanism thiab III hom DC electromagnetic khiav haujlwm mechanism. Txhua lub tshuab ua haujlwm tuaj yeem koom tes nrog breaker lub cev tau zoo heev.
