Cov neeg feem coob tshuab fuse los ntawm qhov ua yuam kev thaum lawv siv hluav taws xob ntau dhau los ntawm cov khoom siv lossis hluav taws xob hauv tsev. Txawm li cas los xij, koj tuaj yeem ua qhov no ntawm koj tus kheej siv cov khoom siv yooj yim. Qhov no tuaj yeem yog txoj hauv kev zoo los qhia seb yuav ua haujlwm li cas, qhov hluav taws xob, thiab amps ua haujlwm li cas. Ua nrog ceev faj, vim qee qhov fuses tuaj yeem tawg thaum lawv tshuab. Cov hnab looj tes tiv thaiv thiab tsom iav tuaj yeem tiv thaiv kev raug mob thaum ua qhov kev sim no.
Cov kauj ruam
Txoj Kev 1 ntawm 2: Ntu Kuv: Sib Sau Koj Cov Khoom
Kauj Ruam 1. Tau txais lub fuse
Muaj ob hom tseem ceeb ntawm fuses: cylindrical thiab plug fuses. Cylindrical fuses suav nrog ib txoj hlua ntawm fusible hlau uas tau muab ntim rau hauv cov raj lossis cov thooj voos kheej kheej. Hom fuse no feem ntau yog siv hauv cov khoom siv. Cov fuse ntsaws feem ntau yog siv los tiv thaiv hluav taws xob hauv tsev thiab suav nrog cov hlau hlau los ntawm qhov uas tam sim no yuav tsum ntws. Cov no tau muab tso rau hauv hluav taws xob hluav taws xob kom tam sim no ntws los ntawm cov hlau hlau txhawm rau ua kom tiav cov Circuit Court. Cov no feem ntau muaj lub qhov rai hauv lub ntsaws kom koj tuaj yeem pom qhov xwm txheej ntawm cov hlau hlau.
- Yog tias tam sim no dhau los ntawm lub fuse, cov hlau hlau yuav sov rau nws cov ntsiab lus melting thiab tawg. Qhov no yog dab tsi tshuab lub fuse.
- Ampere, lossis nws lub npe "amp", yog chav tsev uas siv los ntsuas ntsuas hluav taws xob. Tam sim no tuaj yeem txhais tau tias yog suav ntawm cov naj npawb ntawm cov hluav taws xob uas khiav hla lub voj voog. Ib qho amp yog tus nqi tam sim no uas ua los ntawm ib volt.
- Kev ntsuas ampere ntawm fuse yog ua raws tus naj npawb ntawm amps (piv txwv li cov nqi hluav taws xob tam sim no) lub fuse tuaj yeem tswj hwm ua ntej nws yuav tshuab.
Kauj Ruam 2. Tau txais lub hwj chim thiab cov xov hlau
Koj yuav tsum muaj lub zog siv hluav taws xob nrog kev ntsuas ampere ntau dua li koj lub fuse ampere-rating. Thiab zaum kawg ob lub xov hlau uas yuav txuas lub hwj chim thiab lub fuse. Ampere-ntsuas ntawm cov xov hlau yuav tsum ntau dua lossis sib npaug rau lub zog-muab ampere-ntsuas.
- Txhawm rau tshuab lub fuse, tus naj npawb ntawm amps tsim los ntawm lub hwj chim thiab cov xov hlau yuav tsum ntau dua li lub fuse. Thaum koj xav tshuab lub fuse koj yuav tsum paub tseeb tias koj tau tso ntau lub amps los ntawm lub fuse ntau dua li nws tuaj yeem ua tau.
- Lub hwj huam tuaj yeem yog roj teeb. Cov xov tooj tooj liab yog cov khoom siv hluav taws xob zoo. Cov no, thiab feem ntau fuses, tuaj yeem yuav los ntawm cov khw muag khoom kho vajtse feem ntau. Sab laj ntim rau amperage kev ntaus nqi.
Kauj Ruam 3. Txais thiab hnav cov iav tiv thaiv
Qee qhov fuses tuaj yeem tawg, yog li koj yuav tsum tiv thaiv koj tus kheej los ntawm kev phom sij nrog tiv thaiv iav.
- Cov xov tuaj yeem kub thaum lub zog xa khoom hla lawv. Tsis tas li nco ntsoov tias cov xov hlau yog cov siv hluav taws xob. Txhawm rau txhawm rau ua kom muaj kev nyab xeeb no, xyuas kom koj muaj hnab looj tes ua los ntawm 100% roj hmab, vim qhov no tsuas yog txoj hauv kev kom tiv thaiv koj tus kheej los ntawm qhov kub thiab hluav taws xob tam sim no ntawm koj cov xov hlau. Roj hmab yog ib qho insulator los ntawm hluav taws xob tam sim no.
- Nws kuj yog lub tswv yim zoo los hnav tsom iav tiv thaiv koj lub qhov muag los ntawm iav lossis yas pov tseg uas yuav tshwm sim los ntawm qhov fuse tawg.
Txoj Kev 2 ntawm 2: Ntu II: Txuas thiab Tshuab Fuse
Kauj Ruam 1. Txuas lub hwj huam hluav taws xob rau cov xov hlau
Txhawm rau tshuab koj lub fuse, koj yuav tsum tsim kom muaj kev siv hluav taws xob zoo, xov hlau, thiab fuse.
- Txhua qhov khoom siv hluav taws xob, xws li roj teeb, yuav muaj lub davhlau ya nyob twg zoo thiab tsis zoo. Nov yog qhov uas koj yuav tsum txuas koj cov xov hlau mus rau koj lub zog siv.
- Muab ib lub xaim tso rau ntawm qhov tsis zoo ntawm koj lub zog siv.
- Muab lwm tus tso rau ntawm lub davhlau ya nyob twg zoo ntawm koj lub zog siv.
Kauj Ruam 2. Txuas cov xov hlau mus rau qhov kawg ntawm lub fuse
Qhov no yuav ua kom tiav cov hluav taws xob xav tau los khiav hluav taws xob tam sim no los ntawm lub fuse los ntawm cov khoom siv hluav taws xob.
Xyuas kom cov xov hlau tau kov ob qho kawg thiab qhov tsis zoo ntawm lub davhlau ya nyob twg nrog rau ob qho kawg ntawm lub fuse. Yog tias tsis muaj kev sib cuag tiav, lub Circuit Court tsis ua tiav thiab tsis tuaj yeem ua hluav taws xob
Kauj Ruam 3. Txheeb xyuas kev nyab xeeb
Qee qhov fuses tuaj yeem tawg, yog li nws yog theem tseem ceeb kev nyab xeeb kom paub tseeb tias koj lub iav tau hnav zoo ua ntej tig lub hwj chim.
Koj yuav tsum tsis txhob ua haujlwm ze ntawm cov khoom siv hluav taws. Cov hluav taws xob hluav taws xob tuaj yeem tsim hluav taws xob uas tuaj yeem ua rau cov kua ua kom kub hnyiab thiab cov khoom kub hnyiab tau qhuav
Kauj Ruam 4. Qhib lub hwj chim
Tam sim no lub fuse yuav tsum tshuab. Ua nrog ceev faj.
Yog tias koj lub fuse tsis tshuab, txuas lub hwj chim thiab xyuas kom pom tias koj lub xov tooj txuas tau txuas nrog. Txheeb xyuas kom paub tseeb tias cov hlua hlau sab hauv lub fuse zoo li qub. Yog tias nws tsis yog, lub fuse twb tau tawg lawm thiab koj yuav tsum sim lwm lub fuse sib txawv. Yog tias koj siv lub roj teeb ua lub zog siv, sim kom pom tias nws ua haujlwm tau zoo
Lub tswv yim
- Qee qhov fuses tuaj yeem tawg, yog li nws yog qhov zoo tshaj plaws los tiv thaiv iav rau koj lub cev thiab ntsej muag.
- Nco ntsoov tias koj ua raws cov lus qhia tshwj xeeb hais txog kev ntsuas ampere. Koj tuaj yeem rhuav tshem lub hwj chim thiab/lossis cov xov hlau yog tias koj tsis ua raws cov lus qhia no.
Lus ceeb toom
- Cov xov hlau tuaj yeem ua kom sov dua yog li siv cov hnab looj tes tiv thaiv.
- Khaws deb ntawm cov khoom tawg yooj yim thaum ua qhov kev sim no.
- Cov kev sim zoo li no tuaj yeem ua rau muaj txim taws, uas yog qhov phom sij txaus ntshai.
