Thaum koj tuav txoj hlua khi rau hauv koj txhais tes, nws yuav zoo li yooj yim - Tsuas yog ib daig ntawm xaim npog hauv rwb thaiv tsev. Tab sis koj puas paub tiag tiag yog tias nws nqaHloov pauv tam sim no (AC)lossisncaj qha tam sim no (DC)?
Siv cov cable tsis ncaj ncees tuaj yeem ua rau cov khoom tsis ua haujlwm, kev nyab xeeb kev nyab xeeb, kev poob siab, thiab txawm tias kim heev.
Koj puas tau xav tias:
Puas yog cov vaj huam sib luag hnub ci no xa ac lossis dc?
Kuv tuaj yeem hloov cov ntaub ntawv hluav taws xob DC no nrog cov neeg siv hluav taws xob hauv tsev?
Kuv tuaj yeem kuaj sai npaum li cas thiab paub meej tias hom cable?
Hauv phau ntawv qhia no, peb yuav taug kev koj ntawm txhua yam koj xav paub txog yuav ua li casQhia seb yuav hais rau cable yog ib lossis DC, qhia txog qhov sib txawv ntawm ob, qhia cov lus qhia ua yuam kev, thiab muab cov tswv yim ua yuam kev ntawm kev xaiv cable txoj cai.
Thaum kawg, peb mam li ua li casDongguan Ntau Ntau Hlau & Cable Co., Ltd.thiab pebAC90 SeriesCov khoom tuaj yeem pab koj kom muaj kev nyab xeeb dua, ua tau zoo dua, thiab kev siv hluav taws xob zoo.
Dab tsi yog AC cable thiab DC cable?
Ua ntej paub lawv, cia peb txhais tau tias txhua yam txhais tau li cas.
Ac Cable (hloov cov cable tam sim no)
IbAc Cableyog tsim los hloovHloov pauv tam sim no{{0- Cov Hluav Taws Xob Hluav Taws Xob uas tau rov qab los thiab sib txawv ntawm cov kab ke (feem ntau 50 HZ lossis 60 HZ).
- Cov Kev Siv Raug:Cov Khoom Siv Hluav Taws Xob Hwj Chim, Machinery, HVAC tshuab, teeb pom kev zoo, thiab sab nraud.
AC cabes feem ntau xav tau cov kev tsim tshwj xeeb xws li rwb thaiv tsev lub zog, tiv thaiv, hauv av, thiab kev ua tau zoo.
DC Cable (Ncaj Nraim Cable Cable)
Ib DC Cable nqancaj qha tam sim no, qhov twg cov hluav taws kub ntws tawm ruaj khov nyob rau hauv ib qho kev taw qhia thiab tswj txoj kev ntsuas theem tas li.
- Cov Kev Siv Raug:Kev sib txuas roj teeb, Hnub ci photovoltaic (PV) cov tshuab, hluav taws xob tsheb, cov khoom siv hluav taws xob, thiab khoom siv hluav taws xob.
Cias muab:
Ac CABLE AD ADCRATING tam sim no; DC cables Xa tas mus li tam sim no.
Txawm li cas los xij, hauv kev xyaum, nws tsis pom tseeb los ntawm cov tsos ntawm cov tsos - Qhov no yog vim li cas peb xav tau ib qho kev sib txawv ntawm lawv cov kev sib txawv thiab cov qauv qhia.
Qhov sib txawv ntawm AC thiab DC cables
Nkag siab txog cov kev sib txawv pab koj ua kom cov kev txiav txim siab raug tseeb thiab zam kev siv tsis siv.
| Yam | Ac Cable | DC Cable |
|---|---|---|
| Tus Kws Ciav Hlau & Tus Qauv | Feem ntau - tus tub ntxhais (peb {1} {{-}}}}} | Feem ntau yog ob {{{- cov tub ntxhais (zoo & tsis zoo) lossis ib qho- tus ncej |
| Cov yam ntxwv hluav taws xob | Raug rau daim tawv nqaij cov nyhuv thiab txoj kev xav txog ntawm zaus, ua rau muaj kev cuam tshuam ntau dua | Nqa tsuas yog khov kho tam sim no, tsawg kawg nkaus, tsis muaj zaus |
| Kev thaiv tsev yuav tsum tau ua | Yuav tsum tiv taus hloov pauv cov hluav taws xob polarity thiab peaks; Kev pheej hmoo ntawm ib nrab tawm thiab corona | Kev ntxhov siab tas li; Yooj yim rwb thaiv tsev yuav tsum |
| Raug Cai Raug Cai | Ntau txoj kev nyuaj ua txhaum rau ntau - txheej rwb thaiv tsev, tiv thaiv, thiab grounding | Yooj yim, feem ntau yog tus nqi qis |
| Kev Sib Kis Sib Kis | Haum rau high - voltage ntev - deb hluav taws xob | Zoo heev rau qhov tshwj xeeb ntev - deb lossis qis {- voltage dc tshuab (piv txwv li ntawm HVDC, PVS) |
| Kev Siv Cov Ntaub Ntawv | Fais fab ci, lub cev muaj zog, vaj tse, kev lag luam | Hnub ci Panels, Roj Teeb, Tsheb, Telecom, Electronics |
Piv txwv li:
Lub DC Cable feem ntau muaj ntau dua kev ua haujlwm ntau dua li kev ncua luv, thaum ib qho kev hloov pauv ntawm kev hloov kho yooj yim.
Yuav qhia li cas yog tias cable yog AC lossis DC
Muaj ob peb txoj hauv kev los txiav txim siab hom cable uas koj tau sib tham nrog.
Khij rau Cable daim ntawv lo lossis khij
Feem ntau cov clesles tau luam tawm cov ntaub ntawv ntawm sheath - xws li ntsuas hluav taws xob, qauv, thiab cov ntawv thov tau. Saib cov lus qhia zoo li:
- "AC 220V / 240V / 480V"
- "DC 12V / 24V / 1500V"
- "PV1-f DC" lossis "Hnub Ci DC cable"
- Daim Ntawv Pov Thawj Cov Cim (UL, CE, TUV, PV qauv)
Yog tias daim ntawv lo no suav nrog "PV," "" "" lossis "ncaj qha tam sim no," nws yog rau DC siv.
Yog tias koj pom "AC" lossis voltage ntsuas zoo li "0.6 / 1kv ac," nws yog rau kev hloov tam sim no.
Tswv yim:Qee cov cables yog dual - Nyob (AC / DC). Nco ntsoov xyuas qhov siab tshaj plaws ntsuas hluav taws xob thiab cov zaus.
Txheeb xyuas hom txuas txuas
Lub txuas tau feem ntau qhia txog kev npaj siv:
- AC cables:Phab Ntsa Plugs, Industrial Peb {{{- theem txuas txuas, IEC sockets, NEMA plugs.
- DC cables:Barrel -} Hom DC Cov Khoom Siv DC, USB Cov Qhwv, MC4 Connectors (Hnub Ci), Lub Sijhawm Txuas Ntxiv, Automotive Terminals.
Yog tias lub txuas txuas nrog kev sib txuas nrog lub cim zoo / tsis zoo, nws yuav muaj dc.
Yog tias nws yog lub tiaj tus prong lossis qauv ntsaws, nws yog AC.
Ntsuas nrog multimeter ntau lossis oscilloscope
Cov txheej txheem txhim khu kev qha tshaj plaws:
Nyab xeeb txuas lub cable rau nws lub zog.
Siv amultimeterTxhawm rau tshuaj xyuas voltage hom:
- Ruaj khov, nyeem ntawv tas mus li →Dc
- Hloov pauv lossis sinusoidal voltage →AC
Siv ib qhooscilloscope:
- Sinusoidal lossis ntu nthwv dej →AC
- Ncaj, kab kab →Dc
Nco ntsoov kev nyab xeeb: Disconnnect cov khoom thauj khoom thiab zam dhau - kab ntsuas tsuas yog koj tau kawm.
Saib xyuas daim ntawv thov ib puag ncig
- Lub zog hluav taws xob, cov tsav tsheb, thiab hvac systems →AC
- Hnub ci panels, roj teeb, hluav taws xob, thiab cov tsav tsheb →Dc
- Hauv PV system, hnub ci panels rau inverter =Dc, inverter rau Grid =AC
Sib xyawdaim ntawv lo, txuas, kuaj cov txiaj ntsig, thiab kev siv kev sivyuav muab koj cov kev ntseeg siab, cim tau yog.
Cov kev ua yuam kev thaum siv AC thiab DC cables
Txawm cov kws tshaj lij tej zaum yuav siv cov cable siv tsis siv. Cia peb xyuas cov teeb meem nquag thiab lawv cov kev txaus ntshai.
Kev sivAC CABLEHauv DC Systems (lossis Vice Versa)
Qhov no tuaj yeem ua:
- Kev thaiv kev tsis ua hauj lwmlossisKev Tso Tawm Ib nrab(vim kev ntxhov siab ntau ntxiv)
- Overheatinglossiskev poob siablos ntawm mismatched tus neeg saib xyuas kev tsim qauv
- Suab nrov lossis cuam tshuamlos ntawm kev tiv thaiv tsis zoo
- Kev cai tsis yog - ua raws(Ntau thaj tsam muaj tshwj xeeb DC cable qauv)
Tsis ncaj ncees lawm cable loj
Tus ntoo khaub lig tsis raug - ntu ntu ua rau:
- Ntau dua cov cua sov tsim
- Voltage poob thoob plaws ntev khiav
- Txo lub neej thiab kev ua tau zoo
Mismatched connector
Xoob los yog incomple sib txuas yuav ua rau kev sib cuag siab tsis kam, lossis txawm tias hluav taws xob arcing - nyob rau hauv DC tshuab uas nyob qhov twg polarity uas muaj kev sib deev.
Kev Tsis Txaus Ntseeg
Siv sab hauv -} rated Cable tawm sab nraud tsis muaj UV kev tiv thaiv lossis huab cua kuj tuaj yeem ua rau muaj kev tiv thaiv thaum ntxov, lossis xeb.
Sib xyaw Ac thiab DC kab hauv tib qho conduit
Khiav ob qho tib si ua ke tuaj yeem tsim cov kev cuam tshuam hluav taws xob, txo lub neej rwb thaiv tsev, thiab nce kev nyab xeeb kev phom sij.
Cov lus qhia rau xaiv txoj cai cable
Tam sim no koj nkag siab qhov sib txawv, ntawm no yog yuav ua li cas thiaj li xaiv, kev xaiv kev tshaj lij.
