Dab tsi yog qhov txawv ntawm DC thiab AC fais fab qhov hluav taws xob?
Mar 30, 2023
Direct tam sim no (DC) fais fab qhov (socket) thiab alternating tam sim no (AC) fais fab sockets ob qho tib si muab lub zog hluav taws xob uas xav tau los siv rau ntau yam khoom siv thiab khoom siv. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm ob qho ntawm lawv txoj haujlwm thiab kev siv.
Lub zog hluav taws xob ncaj qha (DC) yog hom hluav taws xob hluav taws xob uas ntws hauv ib qho kev taw qhia, los ntawm qhov zoo mus rau qhov tsis zoo ntawm lub roj teeb lossis lub zog hluav taws xob. DC fais fab sockets feem ntau yog siv nyob rau hauv tsis tshua muaj hluav taws xob thiab hluav taws xob daim ntawv thov, nrog rau cov mobile pab kiag li lawm xws li smartphones thiab laptops, raws li zoo raws li portable pab kiag li lawm xws li koob yees duab thiab xov tooj cua. Qhov hluav taws xob ntau tshaj plaws rau DC lub qhov hluav taws xob yog 12 volts, tab sis muaj lwm qhov voltage siv rau lub hom phiaj tshwj xeeb.
Alternating tam sim no (AC) fais fab yog hais txog hluav taws xob lub zog uas tas li thim rov qab nws cov kev taw qhia ntawm kev khiav, feem ntau ntawm 50 mus rau 60 cycles ib ob. AC fais fab sockets yog siv rau cov khoom siv hluav taws xob ntau dua thiab cov khoom siv hluav taws xob ntau dua, nrog rau cov khoom siv xws li tub yees, cua txias, thiab tshuab ntxhua khaub ncaws, nrog rau kev siv tshuab thiab teeb pom kev zoo. Tus qauv voltage rau AC fais fab sockets yog 110 mus rau 120 volts nyob rau hauv North America, thiab 220 rau 240 volts nyob rau hauv lwm qhov chaw ntawm lub ntiaj teb no.
Qhov sib txawv loj ntawm DC thiab AC lub zog hluav taws xob yog hom lub zog uas lawv muab. DC lub zog yog yooj yim dua thiab muaj txiaj ntsig zoo hauv nws qhov kev xa tawm ntawm lub zog vim tias nws ntws hauv ib qho kev taw qhia xwb, thaum AC lub zog hloov pauv nws txoj kev khiav. DC lub zog kuj tseem tsawg dua rau ntau hom kev cuam tshuam thiab suab nrov uas tuaj yeem tshwm sim hauv AC lub zog hluav taws xob. Txawm li cas los xij, AC lub zog muaj ntau yam thiab muaj peev xwm siv tau ntau yam khoom siv thiab cov tshuab, los ntawm cov khoom siv hluav taws xob qis rau cov tshuab loj loj.
Lwm qhov sib txawv ntawm DC thiab AC fais fab sockets yog hom plug lossis connector uas yuav tsum tau ua kom muaj kev sib txuas. DC connectors feem ntau me me thiab muaj tsawg tus pins lossis terminals dua li AC connectors. DC plugs thiab sockets yog tsim los kom muaj kev sib haum xeeb thiab siv tau yooj yim dua rau cov khoom siv txawb lossis cov khoom siv txawb. Lawv kuj feem ntau muaj kev nyab xeeb dua, nrog rau kev pheej hmoo ntawm hluav taws xob poob qis lossis luv luv, tshwj xeeb tshaj yog rau cov khoom siv me me uas tau npaj los siv los ntawm cov tsis muaj kev tshaj lij. Meanwhile, AC connectors yog loj thiab complex, nrog ib tug ntau ntawm cov terminals thiab pins. Lawv yog tsim los rau kev siv zog ntau dua thiab ua haujlwm hnyav xws li cov khoom siv loj thiab tshuab.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm DC thiab AC lub qhov hluav taws xob yog nyob ntawm hom hluav taws xob uas lawv muab thiab lawv qhov tsim nyog rau cov ntawv thov tshwj xeeb. DC fais fab mov feem ntau yog siv rau qhov tsis tshua muaj hluav taws xob, cov khoom siv hluav taws xob tsawg uas yog portable lossis mobile thaum AC lub zog muaj ntau yam thiab siv nyob rau hauv cov hluav taws xob ntau dua, cov khoom siv hluav taws xob siab thiab cov tshuab suav nrog cov khoom siv thiab cov tshuab ua haujlwm. DC fais fab txuas feem ntau me dua thiab muaj kev nyab xeeb dua thaum AC connectors loj dua thiab nyuaj dua. Kev nkag siab txog qhov sib txawv ntawm cov qhov (socket) no yog qhov tseem ceeb thaum xaiv lub ntsaws thiab lub qhov (socket) tsim nyog rau cov khoom siv tshwj xeeb lossis cov tshuab.
