PCB yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, txawm li cas los xij, tib neeg feem ntau saib xyuas qhov tseem ceeb ntawm kev nyab xeeb nyob deb thaum ua thiab tswj xyuas PCBs. PCB kev nyab xeeb nrug yog hais txog kev tswj kom muaj kev ncua deb ntawm cov ntsiab lus txaus ntshai thaum ua haujlwm PCBs nrog qhov sib txawv voltages thiab tam sim no kom muaj kev nyab xeeb ntawm tus kheej.
Yog li, tus nqi tsim nyog rau PCB kev nyab xeeb deb yog dab tsi? Ua ntej, peb yuav tsum nkag siab txog cov kev phom sij uas yuav muaj nyob hauv PCBs. Lub siab tam sim no thiab qhov hluav taws xob siab thaum lub sijhawm ua haujlwm PCB yog qhov muaj peev xwm txaus ntshai, yog li ntawd, qhov kev nyab xeeb ntawm PCB yuav tsum xyuas kom meej tias muaj qhov sib nrug txaus ntawm cov neeg ua haujlwm thiab lub voj voog tiv thaiv hluav taws xob, luv luv Circuit Court, lossis lwm yam xwm txheej kev nyab xeeb.
Raws li cov qauv kev nyab xeeb thoob ntiaj teb thiab cov kev tshawb fawb cuam tshuam, qhov kev nyab xeeb ntawm PCB feem ntau yuav tsum muaj ntau dua lossis sib npaug rau qhov kev nyab xeeb yam tsawg kawg nkaus uas yuav tsum muaj los ntawm qib tiv thaiv hluav taws xob. Cov qib tiv thaiv hluav taws xob yog txiav txim siab raws li PCB voltage theem thiab ib puag ncig ib puag ncig, uas nyob ntawm cov yam ntxwv xws li voltage magnitude, fais fab zaus thiab teeb liab zaus, huab cua siab, kub, thiab av noo.
Thaum xaiv qhov tsim nyog PCB kev nyab xeeb deb, nws tseem yuav tsum tau xav txog cov kev cai tshwj xeeb ntawm cov neeg ua haujlwm ib puag ncig thiab kev ua haujlwm. Piv txwv li, thaum PCBs tau siv nyob rau hauv qhov kub thiab txias ib puag ncig, qhov kev nyab xeeb yuav tsum tau nce ntxiv kom tsis txhob muaj kev phom sij.
Kev tsim nyog ntawm PCB kev nyab xeeb nyob deb tuaj yeem pab ua kom muaj kev nyab xeeb ntawm tus kheej ntawm cov neeg ua haujlwm, thaum tseem txhim kho kev ua haujlwm thiab cov khoom zoo. Tsis tas li ntawd xwb, kev tshuaj xyuas thiab saib xyuas cov khoom siv PCB thiab ib puag ncig ua haujlwm kuj tseem ceeb rau kev ua kom muaj kev nyab xeeb, txhawm rau txheeb xyuas thiab tshem tawm cov kev pheej hmoo ntawm kev nyab xeeb.
Hauv peb txoj haujlwm, peb yuav tsum tau ceev faj txog qhov muaj peev xwm txaus ntshai ntawm PCB kev nyab xeeb tsis txaus, teeb tsa kev nyab xeeb kom tsim nyog, thiab ua raws li cov txheej txheem kev nyab xeeb cuam tshuam. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem ua kom muaj kev nyab xeeb tiag tiag thaum lub sijhawm ua haujlwm thiab tsis txhob muaj xwm txheej tshwm sim.
