Lub cev muaj zog rwb thaiv tsev cov kev ua haujlwm
2, kev tiv thaiv kev tiv thaiv
Nyob rau hauv qhov kev txiav txim ntawm qhov hluav taws xob, muaj ib qho me me ntws tawm tam sim no ntws los ntawm cov khoom siv insulating. Ib feem ntawm qhov tam sim no ntws los ntawm sab hauv ntawm cov khoom; ib feem faib los ntawm qhov chaw ntawm cov khoom. Vim li no, txoj kev tiv thaiv kev tiv thaiv tuaj yeem raug cais tawm mus rau hauv qhov ntim ntawm qhov tawv nqaij thiab qhov quav tawv. Lub ntim lub cev tiv thaiv ua rau lub qhov hluav taws xob ua ntawm cov khoom hauv ohm-meters; qhov kev tiv thaiv ntawm lub cev tawv nqaij yuav ua rau tus cwj pwm ntawm cov khoom siv hauv ohms. Lub cev ntim ntawm qhov insulating yog feem ntau nyob rau hauv qhov ntau ntawm 107 mus rau 1019 m • m. Qhov hluav taws xob tiv thaiv ntawm cov khoom siv insulating feem ntau muaj feem xyuam nrog cov nram qab no.
● Thaum ntsuas kub nce siab, kev tiv taus txo qis tshaj tawm.
● Dej tuaj yeem txhawb kev sib cais ntawm cov ncov qaumteb qabteb, yog li cov khoom tiv thaiv kom qis qis dua nrog cov av qis, thiab nws yog ntau dua cov khoom ntxeem tau (xws li cov ntawv tho insulating). Cov tshuaj hydrophilic xws li cov ntaub qhwv polar tau yooj yim tsim cov txheej txheem dej nruam ntawm cov nplais kom txo tau cov dej tsis zoo; ib yam khoom uas tsis yog hnav cev xws li ceramics, polytetrafluoroethylene los yog cov zoo li tsis tsim ib txheej dej ntim rau hauv qhov chaw, thiab yog li muaj feem xyuam rau ntawm qhov tawv tiv thaiv ntawm nws.
● Cov khoom xwv txheej hauv cov khoom siv thev naus laus zis feem ntau tsim kev tawm suab, uas tuaj yeem txhawb kev sib cais ntawm cov qauv ncov qaumteb qab zib thiab ua rau kom tsis muaj teeb meem sai.
● Nyob rau hauv qhov kev txiav txim ntawm lub zog hluavtaws xob siab, lub zog ntawm kev tsom kwm ntawm cov tsiv tuaj yeem nce, thiab qhov no ua rau nws txo qis.
3. Dielectric coefficient ntawm insulating khoom
Daim dielectric sib thooj ntawm cov khoom siv insulating qhia tias lub xeev uas tus sab hauv ntawm cov insulating khoom tsiv raws li qhov kev txiav txim ntawm lub teb hluav taws xob, uas yog, cov degree ntawm polarization. Feem ntau, nws txo cov kauj ruam los ntawm kauj ruam raws li cov zaus ntawm qhov hluav taws xob nce; nws nce li cov khoom absorbs ya raws; thiab vim hais tias ntawm tus ntawm kub ntawm polarization, ib tug ncov tshwm sim nyob rau ntawm ib tug tej yam kub.
Yog tias koj xav yuav ib lub tshuab kho mob, thov koj faj seeb rau cov tsav tsheb ncaj qha ncaj qha.
