Lus piav qhia luv luv:

Lub HM4 nruab nrab-voltage Circuit Court breaker siv sulfur hexafluoride (SF6) gas li lub arc-extinguishing thiab insulating nruab nrab. SF6 roj muaj cov yam ntxwv ua kom du, thiab thaum tawg tam sim no hauv nws, tsis muaj qhov tshwm sim tam sim no thiab tsis muaj kev ua haujlwm overvoltage yog tsim. Cov yam ntxwv zoo heev no ua kom ntseeg tau tias lub tshuab hluav taws xob muaj hluav taws xob ntev. Ntxiv mus, thaum lub sijhawm ua haujlwm, nws tsis muaj kev cuam tshuam rau cov khoom siv poob siab, qib dielectric, thiab thermal stress. Cov ncej ncej ntawm lub Circuit Court breaker, uas yog, lub arc-extinguishing chamber, yog ib tug txij nkawm-dawb kaw system rau lub neej. Nws lub neej sealing ua raws li IEC 62271-100 thiab CEI17-1 cov qauv.
