Lub luag haujlwm thiab kev ua haujlwm ntawm cov khoom siv fais fab tiav
Nov 26, 2024|
Tswj thiab tiv thaiv: Raws li kev ua haujlwm xav tau ntawm daim phiaj hluav taws xob lossis lwm lub zog hluav taws xob, qee qhov ntawm cov khoom siv lossis kab raug muab tso rau hauv lossis tawm haujlwm. Thaum cov kab hluav taws xob lossis cov khoom siv hluav taws xob tsis ua haujlwm, qhov tsis zoo yuav raug txiav tawm sai sai ntawm daim phiaj hluav taws xob kom ntseeg tau tias qhov tsis muaj qhov txhaum ntawm daim phiaj hluav taws xob txuas ntxiv ua haujlwm li qub.
Kev rho tawm thiab hauv av: Tom qab cov kab hluav taws xob thiab cov khoom siv uas tsis ua haujlwm lossis yuav tsum tau kho tau raug txiav tawm ntawm daim phiaj hluav taws xob, lawv yuav tsum tau muab cais tawm ntawm cov khoom siv hluav taws xob kom ntseeg tau tias kev ua haujlwm tsis raug thiab overvoltage. Ua ntej kev saib xyuas, peb theem yuav tsum luv luv-circuited thiab grounded kom muaj kev ruaj ntseg ntawm cov khoom siv thiab cov neeg ua haujlwm tu.
Kev faib tawm thiab cov qauv ntawm cov khoom siv fais fab tiav:
Kev faib tawm los ntawm qib voltage: suav nrog qis voltage, nruab nrab thiab siab voltage thiab lub thawv transformer hom.
Kev faib tawm los ntawm cov qauv hauv txee: Hlau enclosed switchgear tuaj yeem muab faib ua armored thiab compartment hom. Lub hom phiaj tseem ceeb yog txwv lub arc nyob rau hauv lub compartment thaum muaj kev cuam tshuam sab hauv arc tshwm sim los xyuas kom meej kev ruaj ntseg ntawm cov neeg ua haujlwm tu.
