Dab tsi yog cov khoom tseem ceeb ntawm shielded cables?
1. Los ntawm qhov teeb meem yooj yim ntawm tag nrho cov khoom, thaum siv cov cables tiav, nws yog ib qho tsim nyog los tiv thaiv lub zog zaus AC voltage ntsuas lub zog ntawm cov tub ntxhais hlau txhawm rau ua lub luag haujlwm zoo dua. Kev xaiv ntawm kev hloov pauv hloov pauv kuj yuav tsum tau saib seb lawv puas nyob hauv thaj tsam ntawm cov txheej thaiv thaiv lossis lwm yam zoo. Niaj hnub no, thaum xaiv cov cables shielded, cov yam ntxwv ntawm cov txheej txheem no yuav tsum tau txiav txim siab kom paub qhov tseeb qhov zoo.
2. Nyob rau hauv qhov kev ntsuam xyuas combustion, nws tseem yuav tsum tau ua ib txoj hauj lwm zoo, saib seb puas tuaj yeem ua kom zoo dua combustion, thiab seb tag nrho cov kev tso tawm ib nrab puas zoo thaum siv? Tom qab nkag siab txog cov no, peb tseem tuaj yeem paub qhov zoo thiab qhov tseem ceeb ntawm qhov uas tau coj los thaum xaiv los nkag siab lawv, uas yuav ua rau peb muaj kev ntseeg siab dua thaum siv lawv. Yeej, cov khoom muag muag zoo hauv khw.
3. Thaum txiav txim siab tshwj xeeb rau kev siv, nws yog ib qho tsim nyog yuav tsum tau ua cov kev sim raws li cov tangent ntawm tag nrho cov dielectric poob lub kaum sab xis. Tsis tas li ntawd, thaum lub sij hawm tus txheej txheem ntawm impulse voltage, yog hais tias cov no muaj peev xwm ua kom pom lawv qhov zoo, peb kuj tuaj yeem paub seb cov cables shielded puas zoo lossis muaj lwm yam txiaj ntsig zoo thaum siv lawv. Txoj kev no, tsis yog peb tuaj yeem yooj yim thaum siv lawv, tab sis peb kuj tuaj yeem paub qee lub ntsiab lus zoo dua.
