Feem ntau hais lus: Raws li tus qauv atmospheric tej yam kev mob, qhov tawg voltage ntawm huab cua qhuav yog kwv yees li 3,000 volts / mm² (ie, 30 kV / cm).
"Air breakdown voltage" tsis yog tus nqi ruaj khov; nws txawv heev nyob ntawm tej yam xws li hluav taws xob teeb tsa, cua txias, nrug, thiab lub sijhawm.
Txhawm rau kom nkag siab "air breakdown voltage," Cia peb saib cov hauv qab no engineering qhov tseem ceeb:
1- Kev nyab xeeb nrug thiab voltage:
Tsawg-voltage kev nyab xeeb:Rau 220V / 380V voltages, qhov kev pheej hmoo ntawm kev tawg ntawm huab cua sib txawv nws tus kheej yog qhov tsawg heev(yuav tsum tau millimeter-qib qhov khoob thiab ntse electrodes).
Qhov kev pheej hmoo tseem ceeb yog kev sib cuag nrog cov khoom nyob.
High -Voltage ceeb toom:Ib qho 10kV fais fab faib hluav taws xob tuaj yeem ntsib corona tawm ob peb centimeters ntawm tus ntiv tes;
Yog tias muaj cov khoom txawv teb chaws nyob rau hauv qhov sib txawv, kev tawg yog qhov ntau dua.
2- Tsim qauv rau "cua pa tawg voltage"
Cov qauv hauv tebchaws muaj cov cai tswjfwm txog kev tshem tawm huab cua ntawm theem thiab hauv av ntawm cov khoom siv hluav taws xob.
Piv txwv li, nyob rau hauv 12kV switchgear, tus qauv qhia ib theem - mus rau -theem clearance ntawm ntau tshaj los yog sib npaug rau 125 hli.
Tus nqi no ntau dua li qhov theoretical tus nqi kom muaj kev nyab xeeb txaus los tiv thaiv kev puas tsuaj los ntawm cov hluav taws xob tsis sib xws, muaj kuab paug, overvoltage, thiab lwm yam.
Interestingly, "Pashin Txoj Cai" tshwm sim hais tias nyob rau hauv cov huab cua tsis tshua muaj siab thiab qhov sib txawv me me, cov huab cua tawg voltage muaj feem xyuam rau cov khoom ntawm (cua siab × qhov nrug deb), thiab muaj qhov tsawg kawg nkaus tawg voltage point.
Piv txwv li, nyob rau hauv lub tshuab nqus tsev los yog nyob rau hauv tej huab cua pressures, txawm ib tug me me qhov sib txawv yuav tawg tau los ntawm ib tug kuj tsawg voltage.
Qhov no piav qhia txog qhov nyuaj ntawm qhov siab - cov khoom siv qhov siab thiab lub tshuab nqus tsev vacuum breaker tsim.
