Nyob rau hauv lub Hoobkas kuaj txheej txheem ntawm cable manufacturing tuam txhab, muaj ib tug siab - zaus misconception nyob rau hauv xaiv ntawmseries resonance kuaj cov cuab yeej- ntau tus neeg yuav khoom tsuas yog tsom mus rau qhov nominal voltage ntawm cov khoom siv, tab sis tsis quav ntsej qhov ntsuas tam sim no thiab tag nrho lub peev xwm. Tom qab cov cuab yeej raug thauj mus rau qhov chaw, nws tau pom tias qhov hluav taws xob tsis tuaj yeem nce thiab qhov taw tes resonance tsis tuaj yeem pom.
Muaj qhov sib txawv tseem ceeb hauv kev sim cov yam ntxwv ntawm cov cables, transformers, GIS thiab lwm yam khoom siv. Cables yog cov qauv siab capacitance, thiab lawv cov capacitance yog proportional rau lawv qhov ntev - lub cable ntev thiab loj dua, lub capacitance siab dua thiab ntau dua qhov yuav tsum tau tam sim no rau kev sim. Ib qho khoom siv uas muaj qhov hluav taws xob txaus tab sis muaj peev xwm tsis txaus tsis tuaj yeem tso tawm qhov ntsuas tam sim no txaus nyob rau hauv lub xeev resonance thaum ntsib txoj kab ntev - deb. Yog li ntawd, thawj qhov pib rau cable Hoobkas xaiv tsis yog qhov voltage siab npaum li cas, tab sis seb lub peev xwm tuaj yeem sib phim.
Wuhan UHV Power Technology Co., Ltd. tau koom nrog kev ua haujlwm siab -voltage hluav taws xob ntsuas rau ze li 22 xyoo. Nws UHV seriessib txawv zaus series resonance test deviceFeem ntau yog tsim los rau AC tiv thaiv kev ntsuas hluav taws xob ntawm cross- txuas cables, hydroelectric generators, lub ntsiab transformers, busbars, GIS, thiab lwm yam. Cov koob no muaj peev xwm ntsuas txij li 75kVA txog 10000kVA (customizable) thiab ntsuas tam sim no ntawm 3A txog 45A (customizable), uas tuaj yeem ua tau raws li cov kev xav tau ntawm - ntev. siab -voltage cables.
Yuav ua li cas kom raug phim lub peev xwm ntawm cables ntawm qhov sib txawv ntev?
Lub peev xwm yuav tsum tau rau kev kuaj cable nyob ntawm peb qhov sib txawv: qib voltage, cross-section, thiab ntev ntawm cable. Noj 10kV / 300mm ² cable ua piv txwv, Wuhan UHV-75kVA / 75kV scheme yog nruab nrog peb lub reactors (txhua 25kVA / 25kV / 1A / 110H), uas tuaj yeem txuas rau tib lub sijhawm kom ua tiav AC tiv thaiv qhov ntsuas hluav taws xob ntawm 1.5km cable. Qhov ntsuas hluav taws xob yog 22kV thiab lub sijhawm kuaj yog 5 feeb.
Yog hais tias lub cable ntev nce mus rau 3km, lub capacitance doubles thiab qhov yuav tsum tau tam sim no kuj nce raws li. Lub tswv yim UHV-135kVA / 108kV yog nruab nrog 4 reactors (txhua 33.75kVA / 27kV), uas tuaj yeem ua tau raws li qhov ntsuas hluav taws xob tiv thaiv ntawm 3km ntawm 10kV / 300mm ² cable los ntawm kev sib xyaw ntawm cov reactors, nrog rau qhov ntsuas zaus ntawm 30-300Hz. Cov tswv yim no tseem tuaj yeem npog qhov hluav taws xob tiv thaiv kev ntsuas ntawm 1km ntawm 35kV / 300mm ² cable, nrog rau qhov ntsuas hluav taws xob ntawm 52kV thiab lub sijhawm sim ntawm 60min.
Rau kev ncua deb cables, UHV-405kVA / 270kV tswvyim yog nruab nrog 6 reactors (txhua 67.5kVA / 45kV), uas tuaj yeem ua tiav qhov ntsuas hluav taws xob ntawm 4.5km rau 10kV / 300mm ² cables. Nyob rau theem voltage ntawm 110kV, lub tswv yim no tuaj yeem ua tau raws li qhov ntsuas qhov ntsuas hluav taws xob ntawm 0.5km rau 110kV / 300mm ² cables, nrog rau qhov ntsuas hluav taws xob ntawm 128kV thiab lub sijhawm sim ntawm 60 feeb.
Qhov tseeb engineering rooj plaub ntawm Wuhan UHV tau tshawb xyuas ntxiv txog qhov muaj peev xwm sib piv ntawm cov cuab yeej. Hauv kev ntsuas hluav taws xob tiv thaiv hluav taws xob hauv Chongqing, Wuhan UHV series series series resonant ntaus ntawv tau ua tiav qhov ntsuas hluav taws xob tiv thaiv rau 8km ntawm 10kV / 300mm ² cable thiab 3km ntawm 35kV / 300mm ² cable. Nyob rau hauv Xinjiang, ib tug customized UHV series seriesseries resonant ntaus ntawvmuaj lub zog loj ntawm 45 kilowatts, deb tshaj qhov xav tau lub zog rau 35kV / 400mm ², 6-kilometer cable kuaj.
Modular Design: Ib qho khoom siv ua si tag nrho cov teb
Cov khoom ntawm lub Hoobkas cable npog voltage theem ntawm 10kV, 35kV, 110kV thiab txawm siab dua, nrog ntev li ntawm ob peb puas meters mus rau ob peb kilometers. Ib qho khoom siv ruaj khov tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev sim ntau yam - modularity yog tib txoj kev tawm.
Lub Wuhan UHV series tau txais ntau ntu series cov qauv sib txuas ua ke ntawm cov tshuab hluav taws xob: cov kev sib txuas ntawm cov reactors tuaj yeem ua rau cov zis hluav taws xob nce ntxiv thiab tsim nyog rau kev ntsuas hluav taws xob siab; Kev sib txuas ntawm cov reactors tuaj yeem ua rau cov zis tam sim no thiab tsim nyog rau siab -muaj peev xwm (ntev cable) kuaj. Los ntawm kev sib xyaw ua ke yooj yim, ib txheej ntawm cov khoom siv tuaj yeem hloov mus rau ntau theem voltage thiab cable ntev, tsis tas yuav yuav khoom siv cais rau txhua qhov tshwj xeeb.
Txhawb nqa qhov zoo tshaj qhov muaj peev xwm uas tsis tuaj yeem tsis quav ntsej
Cov txheej txheem zoo ntawm series resonance tshuab nws tus kheej ntxiv txo qhov kev xaiv pib rau cable factories. Cov khoom siv hluav taws xob resonant tsuas yog xav tau los muab lub zog siv hluav taws xob hauv lub cev, thiab lub zog xav tau rau kev xeem tsuas yog 1 / Q ntawm lub peev xwm ntsuas. Qhov no txhais tau hais tias cov chaw tsim khoom siv hluav taws xob tsis tas yuav teeb tsa lub peev xwm loj rau cov khoom siv hluav taws xob loj rau kev kuaj kab loj, thiab cov khoom siv hluav taws xob zoo tib yam 380V tuaj yeem tsav lawv.
Nyob rau tib lub sijhawm, lubseries resonant ntaus ntawvtshem tawm qhov kev xav tau loj heev - lub zog hluav taws xob tswj cov cuab yeej siv hluav taws xob thiab lub zog ntsuas hluav taws xob hloov pauv, thiab lub cev hnyav thiab ntim feem ntau yog 1/10 txog 1/30 ntawm cov khoom siv kuaj pom zoo. Tag nrho UHV series ntaus ntawv yog lub teeb yuag thiab yooj yim rau siv ntawm qhov chaw. Rau cov chaw tsim khoom siv hluav taws xob, cov khoom siv kev thauj mus los ntawm cov chaw sim sib txawv tsis yog lub nra hnyav ntxiv lawm, thiab tuaj yeem ua tiav yam tsis tas yuav muaj cranes thiab ntau tus neeg ua haujlwm.
Wuhan UHV tau tsim ntau yam txheej txheem kev teeb tsa, uas tuaj yeem siv ncaj qha los ua cov ntawv xaiv. Rau cov kev cai tshwj xeeb, lub tuam txhab tuaj yeem hloov kho lub peev xwm ntsuas, ntsuas hluav taws xob, ntsuas tam sim no, thiab lub sijhawm ua haujlwm tas mus li.
Kev xaiv cov kab hluav taws xob tiv thaiv qhov ntsuas hluav taws xob yog qhov tseem ceeb los xam qhov ntev ntawm lub cable, lub capacitance, thiab qhov xav tau tam sim no. Tsuas yog los ntawm kev xaiv lub peev xwm zoo tuaj yeem ua qhov kev sim ua kom zoo; Kev xaiv yuam kev, txawm tias lub cuab yeej zoo li zoo, nws tsuas yog kho kom zoo nkauj xwb.
