Txawm hais tias koj siv lub fluorescent, chandelier, lossis lub teeb incandescent, koj yuav tsum tau hloov lossis kho lawv ib ntus. Ib qho tseem ceeb tshaj plaws ntawm txoj haujlwm no yog paub qhov sib txawv ntawm kev xaim. Feem ntau cov teeb pom kev zoo muaj cov xaim kub thiab cov xaim nruab nrab. Qee lub sij hawm koj kuj yuav pom ib qho av xaim. Rau kev xaim kom raug, txheeb xyuas cov xov hlau no yog qhov tseem ceeb. Nrog rau qhov ntawd hauv siab, ntawm no yog qee cov lus qhia yuav ua li cas qhia qhov txawv ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom siv teeb pom kev zoo.
Feem ntau, hauv AC teeb pom kev zoo, cov xaim dawb yog nruab nrab thiab cov hlau dub yog kub. Cov hlau ntsuab yog cov hlau hauv av. Txawm li cas los xij, qee qhov teeb pom kev zoo yuav muaj ob lub xov hlau dub thiab ib lub xaim ntsuab. Cov hlau dub nrog dawb kab txaij los yog fins yog cov hlau nruab nrab.
Cov lus tseeb hais txog luminaire thaiv
Feem ntau fixtures yog wired tib txoj kev. Lawv txuas mus rau ib leeg nyob rau hauv ib tug parallel circuits. Cov khoom siv no muaj peb lub xov hlau; kub hlau, nruab nrab hlau thiab av xaim. Txawm li cas los xij, qee qhov kev sib txuas tsis muaj cov xaim hauv av.
AC powered luminaires
AC powered teeb tuaj nrog peb cov xov hlau sib txawv. Cov hlau kub yog cov hlau nyob, thiab cov hlau nruab nrab plays lub luag haujlwm ntawm txoj kev rov qab los. Cov xaim hauv av tsis nqa tam sim no raws li ib txwm muaj. Nws hla tam sim no tsuas yog thaum lub ntiaj teb faults.
Tswv yim: Grounding yog qhov yuav tsum tau muaj kev ruaj ntseg mechanism rau koj cov teeb pom kev zoo.
DC powered luminaires
Thaum nws los txog rau DC lub teeb siv hluav taws xob, cov xaim hluav taws xob sib txawv me ntsis ntawm AC xaim. Cov kab hluav taws xob no muaj cov xaim zoo thiab cov xaim tsis zoo. Ntawm no cov xaim liab yog qhov zoo thiab cov hlau dub yog qhov tsis zoo.
4 kauj ruam qhia kom disassemble lub fixture thiab txheeb xyuas qhov zoo thiab tsis zoo nyob ntawm tej
Yam Koj Yuav Tsum Tau
- Ntsia thawv
- tes haujlwm
- multimeter
- Hlau stripper (yeem)
Kauj Ruam 1 - Faib lub teeb
Tua lub teeb ua ntej. Nrhiav lub Circuit Court breaker uas fais fab lub teeb thiab tua nws. (1)
Kauj Ruam 2 - Tshem tawm lub hau sab nraud
Tom qab ntawd nrhiav cov ntsia hlau tuav lub cev sab nraud ntawm lub teeb. Nyob ntawm seb hom luminaire, cov txheej txheem no yuav txawv. Yog tias koj siv lub chandelier, tej zaum koj yuav tau tshem peb los yog plaub screws.
Tib yam mus rau cov teeb fluorescent. Lub hom phiaj ntawm cov kauj ruam no yog nrhiav cov xov hlau.
Yog li, tshem tawm tag nrho cov teeb meem uas yuav nkaum cov xov hlau.
Kauj Ruam 3 - Tshem tawm cov xov hlau
Tom qab tshem tawm cov txheej txheem, koj tuaj yeem tshawb xyuas cov xov hlau. Rau kev soj ntsuam zoo dua thiab ua pov thawj, rub lawv tawm.
Kauj Ruam 4 - Txheeb xyuas cov xov hlau kom raug
Tam sim no koj npaj txhij los txheeb xyuas cov xov hlau. Ua raws li cov lus qhia no kom raug.
Kev txheeb xyuas cov xov hlau kub thiab hauv av
Yuav tsum muaj peb cov xov hlau. Cov hlau dub yog cov hlau kub. Cov khoom siv feem ntau muaj cov xov hlau dub. Nco ntsoov tias cov hlau yuav tsum yog dub xwb. Yuav tsis muaj cov cim ntawm cov xov hlau, tsuas yog cov ntaub ntawv hais txog cov xaim (qee zaum yuav tsis muaj).
Cov hlau ntsuab yog cov hlau hauv av. Qee zaum, yuav tsis muaj xim rau hauv av xaim. Piv txwv li, qee cov tuam ntxhab siv tooj liab liab qab rau hauv av. (2)
Txiav txim siab cov kab nruab nrab
Kev txiav txim siab cov kab nruab nrab yog me ntsis nyuaj. Feem ntau, cov hlau nruab nrab yog dawb. Txawm li cas los xij, qee qhov khoom siv tuaj nrog ob lub xov hlau dub. Thaum qhov no tshwm sim, muaj ob txoj hauv kev los txheeb xyuas cov kab nruab nrab.
Txoj Kev 1 - Dawb Stripe los yog Ribbed Ntug
Yog tias koj tuaj yeem pom cov xaim dub nrog cov kab dawb dawb lossis cov tav ntawm qhov chaw, nws yog cov hlau tsis huv. Lwm cov hlau yog cov hlau kub dub.
Txoj Kev 2 - Siv tus ntsuas ntsuas
Siv tus ntsuas yog tias koj nrhiav tsis tau cov kab txaij lossis tav ntawm cov xov hlau dub. Thaum koj tso lub tester rau ntawm cov hlau kub, lub tester yuav tsum teeb. Ntawm qhov tod tes, cov xaim nruab nrab yuav tsis tig rau qhov ntsuas ntsuas. Nco ntsoov qhib lub Circuit Court breaker nyob rau theem no thiab strip cov xov hlau yog tias tsim nyog.
Nco ntsoov: Kev siv tus ntsuas ntsuas yog qhov kev xaiv zoo rau txhua qhov xwm txheej saum toj no. Txawm hais tias koj tuaj yeem txheeb xyuas cov xov hlau kom raug, xyuas lawv nrog tus ntsuas dua kom paub tseeb tias txhua yam nyob hauv kev txiav txim.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Yuav ua li cas paub qhov txawv qhov tsis zoo ntawm ib qho zoo
- Dab tsi yog qhov loj me me rau lub teeb
- Yuav ua li cas rau nruab ib lub nruab nrab hlau
