20kV 5000kVA compact transformer substation tseem hu ua sab nraum zoov ua tiav substation, box-type substation, box-type transformer, tseem hu ua substation ua ke, vim nws hloov tau yooj yim ua ke, yooj yim kev thauj mus los, tsiv teb tsaws, yooj yim installation, siv sij hawm luv luv, nqi khiav lag luam, thiab cov hneev taw me me, tsis muaj paug, tsis muaj kev saib xyuas thiab lwm yam zoo, tau txais txiaj ntsig zoo.Vim tias nws yooj yim mus tob rau hauv qhov chaw thauj khoom, lub zog hluav taws xob tuaj yeem txo lub vojvoog ntawm lub zog ntawm lub zog, txhim kho cov khoom siv hluav taws xob zoo, txo cov hluav taws xob poob, thiab txhim kho kev ntseeg siab ntawm cov khoom siv hluav taws xob.Nws yog tshwj xeeb tshaj yog haum rau lub hwj chim daim phiaj transformation.Rockwell lub thawv substation chaw tsim tshuaj paus, lub thawv substation ua tau raws li cov qauv ntawm GB17467-1998 "High thiab Low Voltage Prefabricated Substation" thiab IEC1330.
Nta:
1. Muaj kev nyab xeeb & ntseeg tau
Plhaub feem ntau txais yuav aluminium zinc steel phaj, thav duab nrog cov txheej txheem ntim khoom thiab cov txheej txheem tsim khoom uas muaj kev tiv thaiv corrosion zoo rau 20 xyoo lav.Sab hauv sealing phaj yog ua los ntawm aluminium alloy buckle phaj, thiab cov qhaub cij yog ua los ntawm cov khoom siv hluav taws xob thiab thermal rwb thaiv tsev.Lub tshuab cua txias thiab dehumidification yog ntsia rau hauv lub thawv.Kev ua haujlwm ntawm cov cuab yeej tsis cuam tshuam los ntawm kev nyab xeeb ib puag ncig thiab cov pa phem sab nraud, thiab kev ua haujlwm ib txwm tuaj yeem lav tau nyob rau hauv qhov hnyav ntawm -40 ℃ ~ + 40 ℃.Cov khoom siv tseem ceeb hauv lub thawv yog kaw tag nrho, cov khoom tsis muaj qhov tshwm sim, uas tuaj yeem ua tiav xoom hluav taws xob poob siab, tag nrho cov chaw nres tsheb tuaj yeem paub txog kev ua haujlwm tsis muaj roj, kev ruaj ntseg siab, kev siv thib ob ntawm microcomputer integrated automation system, uas tuaj yeem paub tsis muaj neeg saib xyuas.
2. High degree ntawm automation
Tag nrho cov chaw nres tsheb ntse tsim, kev tiv thaiv system txais microcomputer integrated substation automation khoom, installation, uas muaj peev xwm paub telemetry, tej thaj chaw deb kev sib txuas lus, tej thaj chaw deb tswj, tej thaj chaw deb tswj.Txhua chav tsev muaj kev ua haujlwm ywj pheej.Lub relay tiv thaiv muaj nuj nqi ua tiav, uas tuaj yeem teeb tsa cov kev khiav hauj lwm tsis nyob deb, tswj cov av noo thiab kub hauv lub thawv lub cev thiab ceeb toom cov pa luam yeeb nyob deb, kom ua tau raws li qhov yuav tsum tau ua ntawm tsis muaj leej twg ntawm lub luag haujlwm.Nws tseem tuaj yeem paub. tej thaj chaw deb saib xyuas cov duab raws li qhov xav tau.
3. Hoobkas prefabrication
Thaum tsim, ntev npaum li tus neeg tsim qauv raws li qhov xav tau tiag tiag ntawm lub chaw nres tsheb, muab daim duab kab hluav taws xob loj thiab tsim cov khoom siv sab nraum lub thawv, cov tuam ntxhab tuaj yeem nqa tawm kev teeb tsa thiab kev debugging ntawm tag nrho cov khoom siv, tiag tiag paub txog lub chaw tsim khoom siv hluav taws xob, shorten lub voj voog tsim thiab tsim khoom.On-site installation tsuas yog xav tau lub thawv qhov chaw, cable kev twb kev txuas ntawm lub thawv, tawm cable kev twb kev txuas, tiv thaiv calibration, kis tau tus mob xeem thiab lwm yam commissioning ua hauj lwm.Tag nrho substation los ntawm kev teeb tsa mus rau commissioning tsuas yog xav tau txog 5 ~ 8 hnub, ua rau lub sijhawm siv sijhawm luv.
4. Yooj yim ua ke hom
Lub thawv hom substation qauv yog compact, txhua lub thawv tsim ib qho kev ywj pheej, uas ua rau kev sib xyaw ua ke ntawm kev hloov pauv, ntawm ib sab, peb txhua tus tuaj yeem siv lub thawv, kom cov khoom siv 35kV thiab 10kV tag nrho nruab rau hauv lub thawv, muaj pes tsawg leeg ntawm tag nrho. box hom substation;35kV cov cuab yeej tseem tuaj yeem ntsia sab nraum zoov, thiab 10kV cov cuab yeej thiab kev tswj thiab kev tiv thaiv tuaj yeem ntsia tau rau hauv lub thawv.Qhov kev sib xyaw ua ke no tshwj xeeb tshaj yog tsim nyog rau kev hloov pauv ntawm cov chaw nres tsheb hluav taws xob nyob deb nroog qub.Hauv luv luv, tsis muaj kev sib xyaw ua ke ntawm kev sib txuas ntawm lub substation, thiab tus neeg siv tuaj yeem ua ke qee hom kev ywj pheej raws li qhov xwm txheej tiag tiag kom tau raws li qhov xav tau ntawm kev ua haujlwm nyab xeeb.
European hom substation, yog ua tiav cov khoom siv hluav taws xob hloov hluav taws xob tshiab tsim los ntawm peb lub tuam txhab raws li kev hloov pauv ntawm lub teb chaws hauv nroog network ua kom pom kev sib xyaw ua ke rau cov roj-immersed kaw fais fab transformer thiab siab thiab qis hluav taws xob cov khoom siv hluav taws xob.Los ntawm cov qauv optimization, lub switchgear yuav tsum tau miniaturized mus rau qhov kawg uas zoo heev txo qhov chaw nyob ntawm cov transformer ua ke uas nws ntim tsuas yog sib npaug rau 1/3-1/5 ntawm European box-hom transformers nrog xws li zoo li me me ntim, tsawg. suab nrov, txhim khu kev qha fais fab mov, tsim nyog qauv, blexible rau installation, yooj yim rau kev khiav hauj lwm thiab muaj peev xwm mus tob rau hauv lub load center mus rau qhov siab tshaj plaws, thiab lwm yam. Nws yog dav siv nyob rau hauv lub tsev nyob rau hauv lub quarters coj mus muag chaw chaw nres tsheb industrial thiab mining enterprises tshav dav hlau railroads tsev kho mob tsev kho mob, cov tsev siab thiab qhov chaw.
