Hluav taws xob, qhov yuav tsum tau rau qhov tsawg kawg nkaus qhov kev ncua deb yog hais txog qhov voltage ntawm ob qhov hluav taws xob, qhov to ntawm qhov ntsuas qhov ntsuas ntawm cov khoom siv insulating, thiab cov pa phem ntawm ib puag ncig uas cov khoom siv hluav taws xob nyob.
Qhov tsawg kawg nkaus creepage nrug yog txwv los tiv thaiv creepage ntawm ob conductors los ntawm cov kab mob uas yuav tshwm sim nyob rau saum npoo ntawm cov khoom insulating.
Rau kev siv cov creepage nrug, qhov luv tshaj rwb thaiv tsev nyob nruab nrab ntawm ob lub conductors nyob yuav tsum tau ntau tshaj qhov tsawg kawg nkaus tso cai creepage nrug.
Thaum txiav txim siab hluav taws xob clearances thiab creepage nrug, ntau yam kev siv thiab ib puag ncig yam xws li ntsuas qhov hluav taws xob, cov pa phem, cov ntaub ntawv rwb thaiv tsev, cov duab saum npoo, qhov chaw thiab cov kev taw qhia, thiab lub sijhawm ntev ntawm kev tiv thaiv hluav taws xob yuav tsum raug txiav txim siab. Cov cuab yeej siv siab heev thiab cov qauv khoom muaj xws li cov nqi teev tseg no.
Tshwj xeeb, nyob rau hauv kev siv sib txawv, vim yog hluav taws xob polarization ntawm cov khoom siv insulating nyob ib ncig ntawm tus neeg xyuas pib, cov khoom siv insulating yuav raug them. Lub vojvoog ntawm qhov chaw them nyiaj no (thaum tus neeg xyuas pib yog ncig, thaj chaw them nyiaj yog annular) yog qhov kev ncua deb. Qhov luaj li cas ntawm qhov creepage deb yog ncaj qha ntsig txog kev ua haujlwm voltage, rwb thaiv tsev cov ntaub ntawv, thiab lwm yam. Nyob rau tib lub sijhawm, thov nco ntsoov tias qhov sib txawv ntawm qhov kev siv ib puag ncig kuj yuav muaj kev cuam tshuam, xws li huab cua siab, muaj kuab paug, thiab lwm yam.
Qhov deb ntawm qhov nkag thiab hluav taws xob tshem tawm yog ob lub ntsiab lus sib txawv.
Qhov luaj li cas ntawm qhov hluav taws xob sib txawv nyob ntawm tus nqi siab tshaj ntawm qhov kev khiav hauj lwm voltage, thiab theem overvoltage ntawm daim phiaj hluav taws xob muaj kev cuam tshuam ntau dua rau nws. Qhov kev ncua deb yog nyob ntawm qhov muaj txiaj ntsig zoo ntawm kev ua haujlwm voltage, thiab CTI tus nqi ntawm cov khoom siv insulating muaj kev cuam tshuam ntau dua rau nws. Ob qho xwm txheej yuav tsum tau ua tiav tib lub sijhawm, yog li los ntawm kev txhais, qhov kev ncua deb tsis tuaj yeem tsawg dua qhov hluav taws xob tshem tawm txhua lub sijhawm. Tau kawg, rau ob qho khoom them, feem ntau nws tsis yooj yim sua kom tsim qhov creepage nrug kom me dua qhov sib txawv hluav taws xob.
