Cov tsheb hluav taws xob puas tuaj yeem tiv thaiv cov khau zoo li qub thiab khau ua haujlwm?
Ua ntej tshaj plaws, qhov tsis kam ntawm cov ntaub ntawv los tiv thaiv khoom hluav taws xob thiab cov ntaub ntawv insulating yog txawv. Feem ntau hais lus, qhov tsis kam ntawm insulating ntug yog ntau dua 1012Ω, thiab qhov tsis kam ntawm qhov hluav taws xob tiv thaiv hluav taws xob nyob nruab nrab ntawm 106Ω txog 1012Ω. Cov kab hluav taws xob insulating tsis yog kev coj ua, thiab cov khoom siv los tiv thaiv zoo li qub yog conductive, tab sis tus nqi tsis kam yog loj heev. Cov txheej txheem xav tau yog nyob ntawm 10 ^ 6 thiab 10 ^ 9.
Qhov thib ob, qhov ua tau zoo ntawm kev tiv thaiv khau zoo li qub thiab insulating nkawm khau kuj sib txawv. Cov khau tiv thaiv zoo li qub yog tsim los ntawm kev ntxiv cov khoom siv los tiv thaiv zoo li qub rau ib leeg. Cov khau tiv thaiv zoo li qub muaj qhov ua haujlwm tsis muaj zog, uas tuaj yeem ua rau ntau dhau ntawm tib neeg lub cev mus rau hauv av, zam kev tsub zuj zuj ntawm cov nqi thiab ua rau electrostatic tawm, yog li ua si lub luag haujlwm ntawm kev tshem tawm thiab tshem tawm hluav taws xob zoo li qub ntawm tib neeg lub cev. Cov. Tib qho ntawm cov khau insulated yog ua los ntawm cov khoom siv tsis muaj qhov thaiv, nws tuaj yeem cais tawm tib neeg lub cev los ntawm lub ntiaj teb, yog li ntawd txawm tias tib neeg lub cev kov lub cev conductive, nws yuav tsis ua hluav taws xob sib tsoo.
Thaum kawg, khau los tiv thaiv zoo li qub thiab cov khau insulated muaj ntau hom ntawv thov. Kev tiv thaiv khau zoo li qub feem ntau siv hauv cov tuam txhab hluav taws xob xws li precision hluav taws xob thiab cov khoom siv, cov cuab yeej hluav taws xob, cov tuam txhab tshuaj, thiab lwm yam. Insulated nkawm khau yog qhov tseem ceeb Nws yog los tiv thaiv tib neeg lub cev los ntawm kev cuam tshuam ntawm hluav taws xob. Tsis muaj cov kev cai tshwj xeeb hauv av thiab cov ris tsho tiv thaiv. Nws feem ntau hnav los ntawm cov hluav taws xob hluav taws xob tiv thaiv kauj ruam voltage thiab hluav taws xob, thiab tseem tuaj yeem tiv thaiv hluav taws xob cov teeb meem hluav taws xob vim kev sib tsoo hauv av.
