Dielectric kuaj yog cov txheej txheem kev ntsuas los ntawm kev siv cov ntsuas hluav taws xob rau ib qho hluav taws xob uas dhau qhov nws tsis ua haujlwm. Lub hom phiaj ntawm qhov ntsuas yog txhawm rau txiav txim siab seb qhov khoom tiv thaiv tiv thaiv puas tsim nyog txaus los tiv thaiv tus neeg siv ntawm lub zog hluav taws xob. Qhov kev ntsuas tus qauv no feem ntau tau ua rau cov khoom siv hluav taws xob, xws li cov rooj sib tham hauv Circuit Court, khoom siv hluav taws xob, cab hluav taws xob, hloov hluav taws xob, thiab lub tshuab hluav taws xob. Cov chaw tsim khoom ntawm hluav taws xob tiv thaiv hluav taws xob feem ntau ua qhov kev xeem thaum kawg ntawm cov txheej txheem ntau lawm, siv cov khoom siv tshwj xeeb hu ua dielectric tester.
Yuav luag txhua qhov hluav taws xob tiv thaiv qee qhov nqi hluav taws xob vim muaj ntau yam sib txawv. Qhov ntau me me ntawm qhov tam sim no tau txiav txim siab nyab xeeb rau cov neeg siv, tab sis nyob rau qee qhov xwm txheej, cov ntaub ntawv insulating lossis cov txheej txheem tuaj yeem tawg thiab tso cai rau cov khoom phom sij tuaj rau hauv kev sib cuag nrog tus neeg siv. Xws li hom rwb thaiv tsev tsis zoo qee zaum tuaj yeem ua rau raug mob lossis tuag taus. Kev ntsuam xyuas Dielectric yog qhov tsim nyog los xyuas kom lub tshuab hluav taws xob insulating ntawm hluav taws xob tiv thaiv hluav taws xob yuav tiv thaiv qhov ntsuas hluav taws xob tsis hloov nyob rau hauv ib txwm muaj kev ua haujlwm.
Kev ntsuas sib txawv feem ntau yog ntsuas dielectric kev sib tw. Nyob rau hauv txoj kev ua no, ib qho hluav taws xob hluav taws xob tam sim no tau thov rau feem. Lub tshuab ntsuas tes dielectric kuaj xyuas cov nyiaj tam sim no thaum lub sij hawm ntsuas los txiav txim seb qhov rwb thaiv tsev tsis tau ua tiav. Lub zog hluav taws xob tam sim no tseem siv tau rau lub cuab yeej kom txog thaum lub rwb thaiv tsev tsis ua tiav lossis lub sijhawm ntawm tus txheej txheem tau dhau los. Yog tias lub tshuab insulating tsis swb, cov khoom lag luam feem ntau yog kev nyab xeeb rau kev siv. Cov khoom siv hluav taws xob uas ua tsis dhau lub sijhawm kuaj dielectric feem ntau raug tsim dua tshiab kom ua tau raws li kev nyab xeeb.
Ntxiv rau kev ntsuam xyuas dielectric rhuav tshem, cov txheej txheem hu ua dielectric withstand test kuj tseem ua los txiav txim seb puas muaj qhov tsis xws luag thaum lub sij hawm tsim khoom lag luam. Cov khoom siv hluav taws xob qee zaum muaj qhov tsis xws me, xws li qhov khoob lossis qhov chaw tuaj yeem tsim hluav taws xob luv thaum lub sijhawm ua haujlwm ntawm ib yam khoom. Cov av noo, av noo, ib puag ncig paug, thiab kev co tuaj yeem sib sau los ua hluav taws xob ua rau muaj kev phom sij yog tias cov khoom lag luam tsis raug tiv thaiv ua ntej cov neeg siv. Nyob rau hauv tus txheej txheem no, hluav taws xob hluav taws xob yog muab rau cov khoom tivthaiv ntawm kev ua haujlwm voltage qub. Tus kws ntsuas hluav taws xob sib txuas nrog rau cov khoom siv los saib xyuas cov nqi ntawm tam sim no tam sim no. Yog tias cov dej xau tuaj yeem nyob hauv qhov ntau uas siv tau, cov khoom siv tau pom zoo rau siv.
