Qhov nruab nrab -voltage switchgear ua haujlwm li cas?

Nruab nrab-voltage switchgear (3.6kV txog 40.5kV) faib thiab tiv thaiv lub zog los ntawm cov khoom tseem ceeb xws li cov hluav taws xob hluav taws xob thiab cov khoom sib txuas. Nqus Circuit Court breakers (xws li ZN63 series) siv lub tshuab nqus tsev arc extinguishing (lub sijhawm ua haujlwm Tsawg dua lossis sib npaug li 50ms), thaum SF₆ circuit breakers (xws li LN2 series) cia siab rau SF₆ roj (arc extinguishing efficiency tshaj 100 npaug ntawm huab cua). Ob qho tib si tuaj yeem cuam tshuam luv luv - tam sim no hauv Circuit Court. Cov cuab yeej tiv thaiv, xws li microcomputer-raws li cov cuab yeej tiv thaiv kev sib koom ua ke, saib xyuas qhov tsis sib xws hauv lub sijhawm tiag tiag thiab ua rau muaj kev cuam tshuam hauv kev teb rau luv luv - Circuit Court lossis overload faults. Tam sim no transformers (CTs) hloov siab tam sim no rau hauv 5A / 1A cov cim rau kev saib xyuas. Lub tshuab hluav taws xob siv cov hlau- nyob rau hauv cov qauv, nrog rau kev xaiv rwb thaiv tsev nrog rau huab cua (kev tshem tawm Ntau dua lossis sib npaug li 125mm rau 12kV), cov khoom siv epoxy resin, lossis SF₆ roj (xws li C-GIS keyboards) kom muaj kev sib cais muaj kev nyab xeeb. Cov ntawv thov raug suav nrog cov khoom tawg hauv lub nplhaib tseem ceeb (XGN15-12) thiab ua tiav kev tiv thaiv kev teeb tsa hauv cov kab tawm (KYN28-12).
