Kev ntsuam xyuas dielectric yog ua los xyuas qhov muaj peev xwm dielectric ntawm GIS kev teeb tsa nyob rau hauv txhua qhov kev ua haujlwm tau pom, suav nrog ib ntus thiab ntu ntu overvoltages, thiab yog li koom nrog kev kuaj xyuas lub zog, kev kuaj xyuas hluav taws xob, kev hloov pauv impulse checks, kev kuaj xyuas ib feem, thiab kev ntsuam xyuas ntawm kev pabcuam thiab kev tswj xyuas. circuits. Hauv Table 1, ib qho kev nthuav dav ntawm ntau yam kev ntsuas dielectric. Kev ntsuas hluav taws xob siab xav tau qhov loj ntawm cov khoom siv ntsuas los tsim qhov ntsuas qhov ntsuas hluav taws xob ntawm qee txhiab lossis ntau lab volts.

Kev Tshawb Fawb Dielectric
Cov ntawv pov thawj dielectric tau ua tiav tom qab kev ntsuas txhua lub sijhawm thiab qhia qhov kev ua haujlwm ntawm dielectric ntawm GIS kev teeb tsa, ua kom muaj kev txhim kho kom raug, ua tiav cov khoom tsim los ntawm qhov dielectric qhov pom thiab tsis muaj cov khoom thiab lwm yam pa phem. Rau kev txheeb xyuas niaj hnub, qhov ntsuas dielectric yog lub zog muaj zog tiv thaiv qhov ntsuas hluav taws xob. Impulse verification, xws li teeb pom kev zoo thiab hloov impulse, tsis yog ib feem ntawm kev sim niaj hnub. Ntawm qhov tsawg kawg nkaus ua haujlwm SF6 siab, cov xwm txheej hauv qab no tau txheeb xyuas: theem-rau-lub ntiaj teb, theem-rau-theem (hauv peb theem hauv ib qho kev kaw lus), thiab hla cov ntsiab lus qhib. Ua tiav qhov kev tiv thaiv ib-feeb tiv thaiv theem yam tsis muaj kev cuam tshuam kev cuam tshuam yog qhov tseem ceeb los cim tias qhov kev xeem tau ua tiav. Txhawm rau nrhiav pom cov khoom muaj peev xwm thiab cov teeb meem kev tsim khoom, kev kuaj tawm ib nrab kuj tseem ua ib feem ntawm kev txheeb xyuas cov txheej txheem dielectric.
