Dielectric xeem sivqib siab ntawm kev hloov pauv tam sim no (AC) lossis ncaj qha tam sim no (DC) rau qhov thaiv thaiv qhov thaiv thiab ntsuas cov tshuaj tiv thaiv ntawm cov khoom. AC voltage feem ntau yog siv hauv kev sim dielectric. … Qhov theem ntawm qhov hluav taws xob qhov thaiv qhov thaiv tso cai rau tam sim no ntws yog lub zog dielectric ntawm cov khoom.
Lub zog dielectric txhais tau li cas?
Dielectric zog txhais tau tias yog lub zog hluav taws xob ntawm cov khoom thuam. Nyob rau hauv ib tug txaus muaj zog hluav taws xob teb lub insulating zog ntawm ib tug insulator lov cia cia ntws ntawm tus nqi. Dielectric lub zog yog ntsuas raws li qhov siab tshaj plaws voltage yuav tsum tau tsim ib tug dielectric tawg los ntawm ib tug khoom.
Dab tsi yog qhov txawv ntawm qhov ntsuas dielectric thiab ntsuas qhov ntsuas hluav taws xob?
Txawm hais tias, ob qho tib si dielectric xeem thiab kev ntsuas hluav taws xob zoo sib xws hauv qhov uas lawv muaj cov hom phiaj zoo sib xws, qhov ntsuas dielectric feem ntau ntsuas qhov tawg voltage ntawm qhov tsis muaj zog tshwm sim los ntawm cov teebmeem dielectric ntawm txhua yam uas qhov kev ntsuas rwb thaiv tsev ntsuas qhov zoo ntawm rwb thaiv tsev.
HV test yog dab tsi?
Cov kev ntsuas sib txawv thiab ntsuas tau ua thaum lub sijhawm tu thiab / lossis kev ua haujlwm hauv cov tshuab hloov pauv, lub cev muaj zog, lub tshuab hluav taws xob, thiab lwm yam khoom siv hluav taws xob; Kev ntsuas HV (High Voltage) yog feem ntau siv los txiav txim siab qhov ua tau zoo ntawm cov rwb thaiv tsev uas tso cai rau lawv ua haujlwm nrogkev ntseeg siab thiab kev nyab xeeb, thiab …
Hipot test yog dab tsi?
Kev xeem hipot, muab los ntawm lub sij hawm Kev Ntsuas Siab Muaj Peev Xwm, yog ib daim ntawv thov ncaj qha ntawm qhov hluav taws xob siab rau ib chav nyob hauv kev sim. … Kev tawg ntawm cov rwb thaiv tsev yuav ua rau tam sim no ntws hla cov ntsiab lus ntsuas ntawm Hipot tester, qhov dej ntws tam sim no feem ntau hu ua to.
