Lub khw muag khoom siv vuam muaj ntau yam ntawm transformer, rectifier thiab invert khoom. Vuam inverters yog cov siv dav tshaj plaws - lawv yog cov compact, mobile, yooj yim rau siv, pheej yig, yooj yim rau kev txuas thiab siv tau los ntawm ob tus kws paub txog thiab novice tshwj xeeb. Cov cuab yeej xav tau ib qho tshwj xeeb cable los ua haujlwm. Txog cov hlau uas xav tau rau vuam inverter thiab yuav xaiv nws li cas, saib hauv qab no.
Cov qauv ntawm vuam cable
Ib txwm ua haujlwm ntawm vuam inverter tsuas yog ua tau thaum siv tooj liab, vim tooj liab yog qhov zoo tshaj plaws tus neeg xyuas pib ntawm hluav taws xob. Txoj haujlwm ua haujlwm tau yooj yim heev thaum siv cov kab hloov pauv tau yooj yim.
Vuam inverter xaim muaj:
- Ib tus tub ntxhais tooj liab ua los ntawm cov xov hlau nyias nyias nrog ntu ntu ntawm tsis pub tshaj 0.2 hli.
- Cable cover, uasua los ntawm roj hmab los yog butadiene los yog roj hmab ntuj.
- Adhesion ntawm strands thiab txheej yog tiv thaiv los ntawm ib txheej sib cais ua los ntawm pob tshab zaj duab xis.
Cable specifications
Cov xaim rau vuam inverter yuav tsum muaj qhov yooj yim txaus thiab ua tau raws li qee yam ntxwv:
- Resistant to mechanical stress, tearing and shock.
- Resistant rau qhov kub thiab txias, ua rau lub inverter ua haujlwm ntawm qhov kub thiab txias.
- Resistant rau noo noo thiab ncaj qha tshav ntuj.
- tiv thaiv kab mob, pwm.
- yam tsawg kawg ntawm kev khoov.
Nyob ntawm cov xaim
Tshwj xeeb rau kev vuam, qee lub npe cable tau tsim, tab sis tsuas yog ob - KG thiab KOG - ua tau raws li qhov xav tau saum toj no.
Masters, thaum teb cov lus nug ntawm cov hlau twg rau lub vuam inverter yog qhov zoo tshaj plaws, hu rau lub tshuab hloov pauv (KG). Nws yog siv los txuas cov khoom siv ntawm tes mus rau tes hauj lwm nrog zaus ntawm 400 Hz, qhov siab tshaj plaws hloov hluav taws xob ntawm 660 V thiab qhov hluav taws xob tas li ntawm 1000 V.
Ib qho piv txwv ntawm KG yog ib qho tshwj xeeb hloov tau yooj yim cable - KOG, siv thaum ua haujlwm hauv qhov chaw nyuaj mus txog thiab muab kev ywj pheej ntawm kev txiav txim rau cov vuam thiab txav ntawm lub inverter. Nrog nws cov kev pab, semi-automatic thiab tsis siv neeg kev teeb tsa tau txuas nrog cov tes hauj lwm nrog zaus ntawm 50 Hz, qhov siab tshaj plaws tam sim no ntawm 700 V thiab alternating tam sim no ntawm 220 V.
subtypes ntawm cables
Cov npe npe tau muab faib ua ob peb hom:
- KOG-CL/KG-CL. Txias-resistant xov hlau rau vuam inverter uas tuaj yeem ua haujlwm ntawm qhov kub txog -60 degrees.
- KOG-T/KG-T. tropical cables tiv taus mildew, kub siab txog +55 degrees.
- KGN yog nruab nrog cov rwb thaiv tsev tsis muaj hluav taws xob thiab siv thaum ua haujlwm hauv hluav taws kub hnyav.
- KOG-U. Yuav siv tau nyob rau hauv qhov kub ntawm -45 txog +40 degrees.
Yuav ua li cas cov hlau loj rau vuam inverter kuv yuav tsum xaiv?
Thaum xaiv cov cables rau cov khoom siv vuam, lawv cov ntu ntu yog ib qho ntawm cov kev ntsuas tseem ceeb ntawm cov khoom siv hluav taws xob, thiab vim li ntawd, qhov zoo ntawm cov vuam raug tsim thiab kev ua haujlwm ceev.
Rau cov vuam inverter me me, cables nrog ntu hla mus txog 7 hli yog qhov kev xaiv zoo tshaj plaws2.
Cables nrog ntu ntu ntawm 10, 16 thiab 26 hli yog tsim rau kev ua haujlwm nrog cov khoom siv inverter2.
Siv cov xaim tsis raug rau cov vuam inverters tuaj yeem ua rau kub dhau, luv luv lossis hluav taws kub, uas tuaj yeem ua rau lub cuab yeej puas.
Txuas cables rau vuam inverter
Kev sib txuas ntawm cov khoom siv yog ua raws li ntau txoj cai:
- Cables txuas nrog lub inverter siv cov lug tshwj xeeb, txhua qhov kev sib txuas yuav tsum tau insulated.
- Wires rau vuam inverterua ke los ntawm crimping.
- Yam yuav tsum tau ua - ua raws li polarity thaum txuas rau cov tuav hluav taws xob thiab cov khoom sib txuas.
- Lub zog ntawm cov cables yuav tsum phim lub tshuab vuam.
Yuav tsum muaj rau vuam hlau
Cables rau vuam inverters yuav tsum coj tam sim no mus rau qhov chaw ntawm lub arc nrog tsawg tsawg, thiab yog li ntawd lawv yog ua los ntawm tooj liab, uas muaj lub siab tshaj plaws conductivity ntawm tag nrho cov hlau. Ntu loj tiv thaiv cov hlau los ntawm overheating.
Thaum lub sijhawm ua haujlwm, tus welder yuav tsum ua kom muaj zog txav nrog cov electrode lossis tuav nws ntawm qhov sib txawv. Raws li, cov hlau yuav tsum tsis txhob cuam tshuam. Feem ntau, vuam yog ua nyob rau hauv ib qho nyuaj-rau-mus txog qhov chaw ntawm complex industrial thiab siv, thiab yog li ntawd lub cable yuav tsum tau hloov tau, thiab cov ntaub ntawv insulating yuav tsum resilient thiab elastic.
Vuam ua haujlwm yog ua los ntawm cov qauv hlau, uas yog cov neeg ua haujlwm zoo tshaj plaws ntawm tam sim no, uas yuav tsum tau ua haujlwm ntev ntawm cov txheej txheej insulating, tiv taus kub thiab hluav taws xob. Tsis tas li ntawd, cov rwb thaiv tsev zoo li no yuav tsum tiv taus qhov hnyav, qhov kub thiab txias, torsion, squeezing thiab twisting.
Cov txheej txheem zoo tshaj plaws ntawm cov xaim hlau rau vuam inverter yog ntau cov tub ntxhais tooj liab cable ntawm cov hlaws loj nrog cov txheej txheej insulating ua los ntawm cov roj thiab roj resistant roj hmab. Nws ua tau raws li txhua qhov yuav tsum tau ua rau cov xov hlau zoo li no.
Vuam kab kos
Tus lej cim npe ntawm cov xov hlau rau vuam inverter pib nrog cov ntawv luv uas qhia txog qeb. Piv txwv li, KS qhia txog lub vuam cable, thaum tsab ntawv K qhia txog lub ntsiab lus tooj liab.
KG hom muaj cov yam ntxwv zoo ib yam thiab siv rau vuam hauv tsev.
Cov txheej txheem tiv thaiv polymeric qhia los ntawm tsab ntawv "P". Frost-resistant xov hlau yog cim nrog cov ntawv "ХЛ" thiab tuaj yeem siv rau qhov kub txog -60 degrees vim muaj cov txheej txheem polymer ntxiv uas tiv thaiv kom tsis txhob tawg thaum txias.
Cov kab hluav taws xob kub muaj cim nrog tsab ntawv "T". Cov rwb thaiv tsev ntawm cov xov hlau zoo li no yog ua los ntawm cov ntaub ntawv muaj peev xwm ua haujlwm ntawm qhov kub txog +85 degrees thiab muaj cov tshuaj tua kab mob thiab tshuaj tua kab mob. Lub rwb thaiv tsev tsis poob nws cov txiaj ntsig ntawm qhov kub thiab txias.
KOG yog cov ntawv luv rau cables nrog qib siab ntawm kev hloov pauv. Ua tsaug rau cov leeg no, nws tuaj yeem ua haujlwm vuam hauv qhov chaw nyuaj-mus txog yam tsis muaj kev cuam tshuam rau kev txav ntawm lub cuab yeej thiab kev nplij siab rau cov welder ua cov seams nyuaj.
Cov cores yoog rau cov zaus tam sim no tau cim nrog HF cov ntawv thiab siv rau ob qho tib si kev thiab tsev neeg vuam inverters.
Kev tiv thaiv dej nce ntxiv yog qhia los ntawm KG cim. Cables ntawm nohom tso cai rau underwater ua hauj lwm nrog yuav tsum tau tag nrho waterproofing ntawm tag nrho cov connectors.
Cov kab hluav taws-resistant thiab tsis-combustible cables yog cim nrog cov ntawv GN. Cov xov hlau zoo li no tau siv hauv "kub" ua haujlwm ntawm cov chaw lag luam, thaum tshav kub-kho qhov chaw thiab qhov khoob yog welded.
Tus naj npawb ntawm cov cores yog qhia los ntawm cov lej sib raug. Tus ntoo khaub lig ntawm tus neeg xyuas pib qhia hauv square millimeters.
Kev kos npe ntawm cov xaim xaim xaim rau vuam inverters yog ua raws li lwm cov txheej txheem sau tseg. Cov ntawv xov xwm ntawm qhov tsis sib txawv ntawm cov xov hlau txawv teb chaws tuaj yeem pom thaum yuav nyob.
