Qhov tawg tshwm sim ntawm nruab nrab voltage cables
Raws li cov cuab yeej tseem ceeb rau kev xa hluav taws xob, cov kab hluav taws xob nruab nrab muaj qhov ua haujlwm ntawm kev xa hluav taws xob hluav taws xob. Txawm li cas los xij, thaum lub zog xa hluav taws xob, cables yuav muaj kev puas tsuaj.
nruab nrab voltage fais fab cable tawg yog hais txog qhov tshwm sim uas lub zog hluav taws xob hluav taws xob ntawm lub cable yog siab dhau ntawm qhov kev txiav txim ntawm hluav taws xob, ua rau kev puas tsuaj rau nws cov txheej txheem rwb thaiv tsev. Thaum lub zog hluav taws xob muaj zog tshaj ib qho nqi, cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob yuav raug tshem tawm thiab tsim cov hluav taws xob lub qhov khub. Cov electron qhov khub no yuav tsim cov tshuaj tiv thaiv kab mob thiab ua rau ionization nyob rau hauv txheej rwb thaiv tsev, thaum kawg ua rau cable tawg.
Yog vim li cas rau kev tawg ntawm cable nruab nrab voltage
1. Lub zog hluav taws xob
Lub ntsiab yog vim li cas rau kev tawg ntawm nruab nrab voltage cables yog lub siab hluav taws xob teb lub zog. Lub zog hluav taws xob hauv lub rwb thaiv tsev txheej ntawm lub cable yog txiav txim siab los ntawm qhov hluav taws xob thiab cov duab geometric ntawm lub cable. Thaum lub zog hluav taws xob hauv lub rwb thaiv tsev ntawm cov kab hluav taws xob ntau dua li nws lub zog hluav taws xob puas tsuaj, txheej rwb thaiv tsev yuav tawg.
2. Qhov kawg tiv thaiv hluav taws xob lub zog ntawm dielectrics
Cov ntaub ntawv dielectric muaj qee qhov kev txwv ntawm lub zog hluav taws xob, dhau qhov uas tuaj yeem ua rau cov khoom siv dielectric puas. Yog li ntawd, cov khoom siv dielectric ntawm nruab nrab voltage cables yuav tsum muaj lub zog hluav taws xob txaus los tiv thaiv thiab xyuas kom muaj kev nyab xeeb ntawm cov cables.
3. Cov npuas thiab cov pa phem hauv dielectrics
Cov npuas thiab cov pa phem hauv dielectrics tuaj yeem cuam tshuam rau kev faib hluav taws xob hauv hluav taws xob. Npuas thiab cov pa phem tuaj yeem ua rau muaj qhov sib txawv ntawm cov hluav taws xob hauv hluav taws xob, ua rau lub zog hluav taws xob tsis tshua muaj zog ntawm qee qhov chaw hauv cov txheej txheem rwb thaiv tsev ntawm cov hluav taws xob nruab nrab ntawm cov xaim hluav taws xob, uas ua rau tawg.
Qhov cuam tshuam ntawm mv cable tawg
Kev tawg ntawm nruab nrab voltage fais fab cable tuaj yeem ua rau hluav taws xob tsis zoo, uas tuaj yeem muaj kev cuam tshuam loj rau kev tsim khoom thiab lub neej txhua hnub. Tsis tas li ntawd, tej yam xws li hluav taws kub nyhiab thiab kev puas tsuaj yuav ua rau cov kab hluav taws xob tawg, ua rau muaj xwm txheej.
Nyob rau hauv luv luv, nruab nrab voltage hlau tawg yog ib qho teeb meem loj nyob rau hauv lub hwj chim kis tau tus mob, thiab nws yog tsim nyog los ntxiv dag zog rau cable rwb thaiv tsev tsim thiab txij nkawm kom tsis txhob cable tsis ua hauj lwm los ntawm ntau dhau voltage, dielectric puas, thiab lwm yam yog vim li cas.
