Hom fais fab txuas
Fais fab txuas tuaj yeem muab faib ua ob hom: hloov tam sim no (AC) lossis ncaj qha tam sim no (DC). Thaum xav txog qhov txaus ntshai ntawm cov khoom siv hluav taws xob sib txuas, nws yog ib qho tseem ceeb kom nkag siab txog qhov sib xws thiab qhov sib txawv ntawm ob hom kev sib txuas.
AC- hom fais fab txuas muaj ntau dua, thiab koj pom ntau yam ntawm cov khoom sib txuas hauv koj lub tsev lossis chaw ua haujlwm txhua hnub. AC fais fab plugs thiab receptacles txuas hluav taws xob rau lub tsev hloov tam sim no (AC) thaiv, nrog rau nws tus tswv tsev transformer, uas tswj qhov voltage, thiab muaj peev xwm nqa tam sim no hla ntau kab. Ntawd yog, AC hom connector tuaj yeem ua haujlwm ntawm qhov dav thiab ntau qib.
Raws li lub npe qhia, cov kev taw qhia ntawm cov dej ntws tam sim no hauv chav AC hloov pauv lossis thim rov qab. Txhua qhov kev sib hloov tam sim no suav ua ib lub voj voog, thiab tag nrho cov voj voog yog qhov ntsuas zaus ntawm chav tsev hluav taws xob. Feem ntau cov dej ntws tuaj yeem ua tiav sai thiab ua tiav ntau lub voj voog hauv ib ob. Piv txwv li, tus qauv AC zaus nyob rau hauv North America yog nyob ib ncig ntawm 60 Hz / sec, uas txhais tau hais tias tam sim no khiav ze li ntawm 60 laps nyob rau hauv ib tug thib ob.
DC hom connector, raws li lub npe qhia, tsis muaj lub voj voog, tsis zoo li nws cov kwv tij, AC system. Conversely, DC connector ua hauj lwm nyob rau hauv ib qho kev taw qhia, thiab nws tam sim no ntws los ntawm lub Circuit Court nyob rau hauv ib qho kev taw qhia. Koj yuav pom hom hluav taws xob tam sim no feem ntau pom hauv cov roj teeb thiab cov tshuab hluav taws xob, qhov twg tam sim no feem ntau tsim los ntawm cov roj hluav taws xob sab hauv.
Tej yam uas pheej hmoo:
Txawm hais tias qhov tsos thiab tsim ntawm cov khoom siv niaj hnub no tau txo qis heev ntawm cov tib neeg raug cuam tshuam ncaj qha rau lub neej tam sim no, tau txais hluav taws xob los yog ua rau hluav taws kub vim muaj teeb meem hauv Circuit Court, tseem muaj ntau yam teeb meem cuam tshuam nrog cov khoom siv hluav taws xob.
Extension qaum. Qhov tseeb tau ua pov thawj tias tej yam zoo yog qee zaum tsis yog yam zoo. Cov hlua fais fab uas txuas nrog lub ntsaws thiab tuaj yeem ua kom yooj yim rau koj kom them cov khoom siv hluav taws xob ntau dua, ua rau koj yooj yim dua thiab ua rau muaj kev pheej hmoo ntau dua. Overloading ntawm AC tam sim no nyob rau hauv cov hlua txuas ntxiv tau paub tias yuav ua rau muaj teeb meem xws li overheating ntawm lub system, voltage surges, sab nraud spark sputtering, thiab tej zaum txawm hluav taws. Nco ntsoov xyuas cov hlua txuas ntxiv rau cov kab nrib pleb hauv cov yas rwb thaiv tsev, thiab ua tib zoo saib xyuas kom tsis txhob ntsaws txhua yam rau hauv tib lub voj voog txuas ntxiv thiab tig rau tib lub sijhawm.
dej. Txij li dej yog tus neeg xyuas pib nrog cov khoom siv hluav taws xob zoo heev, lub hwj chim txuas yuav tsum tau ceev kom deb ntawm qhov chaw uas muaj dej. Feem ntau, xws li hauv chav dej, txawm tias qhov me me ntawm cov khoom siv hluav taws xob nrog cov tes ntub dej tuaj yeem ua rau muaj hluav taws xob poob siab. Yog tias cov qauv tsim tau zoo, lub qhov hluav taws xob yuav raug teeb tsa kom deb li deb tau ntawm lub dab dej thiab lub tais da dej. Txhua tus yuav tsum tau ceev faj thaum siv cov khoom siv hluav taws xob nyob ze ntawm qhov dej.
Kev pheej hmoo tsis sib haum. Qee qhov hluav taws xob qub yuav tsis tau hloov kho kom muaj kev nyab xeeb tsim ntawm lawv cov khoom siv niaj hnub no, uas txhais tau hais tias koj tuaj yeem ntsaws qee qhov ntsaws ntsaws rau hauv qhov hluav taws xob tsis raug. Qhov no ua rau muaj kev pheej hmoo ntawm qhov zaus lossis qhov tsis sib xws, uas tuaj yeem ua rau hluav taws kub lossis qhov hluav taws xob tawg. Txawm hais tias qee qhov hluav taws xob tso cai rau qee qhov sib txawv ntawm lub cev hauv cov ntsaws ntsaws, nws yog qhov zoo tshaj plaws los nug tus kws tshaj lij txog koj cov qauv kev nyab xeeb. Yog tias tsis paub meej txog qhov no, siv lub tshuab hloov hluav taws xob hloov hluav taws xob los txo qhov hluav taws xob, txo qhov kev pheej hmoo ntawm kev puas tsuaj mus ntev -.
Uninsulated hlau. Kev tuav tsis raug ntawm cov xaim hluav taws xob thaum lub sij hawm tsim kho lossis hloov kho yuav yog ib qho teeb meem tshwm sim. Qhov no kuj yog ib qho teeb meem txaus ntshai tshaj plaws, yog li muaj ntau yam kev cai lij choj thiab cov kev cai uas twb muaj lawm tau tsim los txo cov kev cuam tshuam ntawm cov kab hluav taws xob. Tsis tas li ntawd, cov kab hluav taws xob hauv qee lub tsev qub yuav raug rwb thaiv tsev ua ntej, tab sis lawv tau muaj hnub nyoog thiab hnav tsis tau ntev, yog li lawv yuav tsum tau xyuas ntau zaus, thiab qee cov khoom siv tsis siv neeg lossis cov tsev uas siv hluav taws xob ntau yog ob npaug insulated. Tsis tshua muaj.
polarization. Polarization yog hais txog qhov tshwm sim nyob rau hauv uas cov kab ntawm lub hwj chim connector yog energized thiab cuam tshuam nrog lawv conductors. Txij li thaum muaj ntau tus neeg xyuas pib nyob rau hauv cov kab hluav taws xob, txhua tus muaj ntau hom receptacle thiab plug insertion ua ke, sab laj nrog ib tus kws tshaj lij hluav taws xob lossis lwm tus kws tshaj lij los txiav txim siab seb qhov polarization puas tseem nyob hauv qhov sib npaug lossis tsis muaj qhov sib npaug. qhov kev xaiv zoo tshaj plaws. Rau feem ntau cov khoom siv hluav taws xob, qhov tsis yog - nyob qhov chaw feem ntau yog sab uas yuav tsum cuam tshuam nrog cov khoom nyob, thiab feem ntau cov qauv tsim, cov polarized (uas yog, cov khoom nyob) sab tsis tuaj yeem cuam tshuam nrog cov tsis yog {{ 1}}polarized qhov chaw. Lub qhov (socket) pauv qhov tam sim no
