Lub luag haujlwm ntawm DC Voltage Regulators
DC tswj fais fab mov ua lub luag haujlwm tseem ceeb hauv kev tsim khoom txhua hnub thiab lub neej, piv rau ntau yam khoom siv hluav taws xob hauv lub tshuab hluav taws xob, DC tswj fais fab mov muaj qhov zoo tshaj plaws, cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob tawm tsis ruaj khov, yuav muaj ib qho kev cuam tshuam rau cov khoom siv hluav taws xob, cov cuab yeej hauv qab no ntiaj teb kev sib koom tes ntawm cov kws tshaj lij los qhia rau koj txog lub luag haujlwm tseem ceeb ntawm DC tswj fais fab mov.
Feem ntau ntawm cov khoom siv hluav taws xob txhua qhov kev ua haujlwm ntawm lub davhlau ya nyob twg yog los ntawm unidirectional conductive Cheebtsam yuav hloov mus rau DC, thiab nrog rau cov khoom siv hluav taws xob uas muaj ntau yam kev lim dej los lim tawm cov khoom sib txuas hauv DC, tab sis cov haujlwm no tseem tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm qee cov khoom siv hluav taws xob ntawm DC tswj fais fab, uas yuav muaj kev cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov khoom siv hluav taws xob, thiab nws qhov cuam tshuam muaj cov hauv qab no:
1, qhov cuam tshuam ntawm qhov input voltage ntau, thaum lub input voltage siab dhau lawm, nws yuav ua rau qee yam ntawm cov khoom siv hluav taws xob ntxiv yog siab dhau los yog siv lub zog ntau dhau thiab kev puas tsuaj, thaum lub zog input tsawg dhau, tab sis kuj yuav ua rau qee yam ntawm kev ua haujlwm tsis zoo, thiab txawm tias tsis tuaj yeem ua haujlwm.
2, qhov cuam tshuam ntawm qhov tsis ruaj tsis khov, piv txwv li, oscilloscope fais fab mov yuav tsum ruaj khov los xyuas kom meej tias lub teeb taw tes ntawm deflection rhiab heev, scanning lub sij hawm thiab lwm yam raug; thiab, piv txwv li, cov voltmeter digital yuav tsum muaj qhov tseeb tsis txaus ntseeg sab hauv lub zog ruaj khov kom ntseeg tau tias qhov tseeb ntawm qhov hluav taws xob / digital hloov pauv.
3, qhov cuam tshuam ntawm cov zis ntau dhau, piv txwv li, DC tswj cov khoom siv hluav taws xob tso tawm hluav taws xob dhau qhov ntsuas hluav taws xob ntawm cov hluav taws xob sib txuas ntawm ntau dua 30%, tuaj yeem ua rau muaj kev puas tsuaj loj rau cov kev sib txuas.
4, qhov cuam tshuam ntawm cov hluav taws xob luv luv, piv txwv li, kev sib txuas lus hauv nroog tsis tuaj yeem muaj hluav taws xob tam sim ntawd, txwv tsis pub kev sib txuas lus thoob ntiaj teb cuam tshuam, ua rau muaj xwm txheej loj; thiab, piv txwv li, khoos phis tawj thiab lwm yam AC fais fab mov, AC uninterruptible fais fab mov yuav tsum tau siv.
Qhov no qhia tau hais tias lub luag haujlwm tseem ceeb ntawm DC tswj cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob, tuaj yeem tshem tawm cov teebmeem no, cov txheej txheem ua haujlwm ntawm cov khoom siv hluav taws xob ua lub luag haujlwm tseem ceeb heev.
