Hauv cov chaw siv hluav taws xob tshiab (xws li photovoltaic fais fab nroj tsuag thiab cua ua liaj ua teb), txawm hais tias qhov siab thiab qis voltage switchgear tsis tsim hluav taws xob, nws yog qhov tseem ceeb rau seb tag nrho cov kab ke tuaj yeem ua haujlwm ruaj khov. Raws li lub peev xwm ntawm lub zog tshiab txuas ntxiv mus ntxiv, cov kev xav tau siab dua tau muab tso rau ntawm kev ntseeg siab, kev hloov pauv, thiab kev txawj ntse ntawm kev txhawb nqa cov khoom siv.
Vim li cas lub zog tshiab fais fab chaw nres tsheb tshwj xeeb xav tau siab -zoo switchgear?
Tsoos thermal fais fab nroj tsuag muab hluav taws xob ruaj khov nrog qhov hloov pauv tsawg kawg nkaus. Tab sis hnub ci thiab cua zog nyob ntawm huab cua, thiab lawv cov zis tuaj yeem hloov tau sai. Qhov kev sib cuam tshuam thiab qhov tsis sib xws no muaj kev cuam tshuam loj rau hauv kab sib chaws, muab cov kev xav tau ntau dua rau kev txhawb nqa cov khoom siv.
Lub sijhawm no, qhov hluav taws xob siab thiab tsis tshua muaj hluav taws xob hloov pauv ua lub luag haujlwm dual hauv kev tswj hwm kev tswj hwm thiab kev ruaj ntseg:
High voltage sab (piv txwv li, 10kV, 35kV): lub luag hauj lwm rau tau txais lub stepped - hluav taws xob lub zog thiab ua hauj lwm tis, tiv thaiv, thiab saib xyuas;
Tsawg voltage sab (feem ntau yog 380V / 660V): siv rau lub zog pabcuam hauv qhov chaw nres tsheb, xws li teeb pom kev zoo, inverter tswj, thiab kev saib xyuas.
Yog tias cov cuab yeej teb qeeb lossis muab kev tiv thaiv tsis raug, qhov poob siab tam sim ntawd tuaj yeem kaw tag nrho lub chaw nres tsheb fais fab, ua rau poob ntawm kaum tawm txhiab yuan.
Thawj kauj ruam: xyuas seb hom qauv puas haum rau daim ntawv thov scenario
Tam sim no, mainstream low-voltage switchgear feem ntau muab faib ua ob hom: tsau thiab tshem tau.
Tsau hom (xws li GGD): cov qauv yooj yim, tus nqi qis, tsim nyog rau cov haujlwm me me nrog cov khoom ruaj khov thiab kev saib xyuas yooj yim.
Hom rho tawm tau (xws li GCS, MNS, GCK): txhua chav ua haujlwm (piv txwv li, lub tshuab hluav taws xob hluav taws xob) tau nruab rau ntawm lub rub -trolley tawm, yog li yog tias muaj teeb meem tshwm sim, nws tuaj yeem raug tshem tawm thiab hloov pauv yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm lwm lub voj voog. Qhov kev tsim no yog tshwj xeeb tshaj yog haum rau loj - nplai, siab automated tshiab zog fais fab chaw nres tsheb. Nws yog tshwj xeeb tshaj yog dav siv nyob rau hauv faib photovoltaic los yog tej thaj chaw deb cua fais fab tej yaam num.
Rau siab -voltage switchgear, hlau-clad tshem tau switchgear xws li KYN28A-12 thiab KYN61-40.5 tau dhau los ua qhov kev xaiv tseem ceeb rau cov chaw nres tsheb fais fab tshiab vim lawv qhov kev ua tau zoo ntawm rwb thaiv tsev, kev cuam tshuam cov tshuab, thiab tsib txoj haujlwm tiv thaiv.
Qee qhov haujlwm tseem xav tau cov cuab yeej siv los txhawb cov kev cuam tshuam digital los pab txhawb kev sib koom ua ke rau hauv cov txheej txheem automation.
Qib thib ob: qhov ntsuas hluav taws xob yuav tsum nruj me ntsis ua raws li cov qauv tsim
Thaum xaiv, cov kev ntsuas hauv qab no yuav tsum tau kuaj xyuas:
Rated ua hauj lwm voltage: qis- cov khoom siv hluav taws xob feem ntau yog 380V, qee qhov xwm txheej kev lag luam lossis cov haujlwm xa tawm tuaj yeem siv 660V; High- cov khoom siv hluav taws xob feem ntau yog 12kV lossis 40.5kV.
Rated tam sim no: Tam sim no ntawm qhov qis -voltage lub tsheb npav loj tuaj yeem ncav cuag 4000A, uas yuav tsum tau txiav txim siab raws li qhov muaj peev xwm thiab thauj khoom ntawm lub transformer.
Luv-circuit breaking peev: Qhov tsawg-voltage Circuit Court breaker yuav tsum muaj peev xwm cuam tshuam qhov xav tau luv luv-circuit tam sim no, uas feem ntau yuav tsum tsis pub tsawg tshaj 50kA; Lub siab -voltage switchgear yuav tsum tau ua kom tau raws li qhov luv luv - qhov yuav tsum tau muaj peev xwm ntawm lub kaw lus thiab dhau qhov kev txheeb xyuas qhov tseeb thermal stability.
Kev tiv thaiv qib: Nws raug pom zoo tias qib kev tiv thaiv ntawm lub txee tsis qis dua IP42 nyob rau sab nraum zoov lossis xuab zeb thiab plua plav ib puag ncig (xws li photovoltaic bases hauv Northwest China) los tiv thaiv cov khoom txawv teb chaws los ntawm kev nkag mus thiab cuam tshuam rau kev ua haujlwm rwb thaiv tsev.
Ib puag ncig tej yam kev mob: nrog rau qhov siab, qhov kub thiab txias, av noo, thiab lwm yam, kev kho cua rwb thaiv tsev yuav tsum tau txiav txim siab nyob rau hauv qhov chaw siab.
Txhua qhov kev ntsuas yuav tsum yog raws li qhov project hluav taws xob thawj qhov system daim duab, tsis txhob empiricism lossis tsuas yog siv cov txheej txheem qub.
Qib peb: kev txawj ntse tau dhau los ua tus qauv kev teeb tsa hauv kev lag luam
Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ntawm daim phiaj ntse thiab kev lag luam digital thiab kev saib xyuas, kev siv hluav taws xob siab thiab qis hluav taws xob feem ntau tau muab cov ntaub ntawv tau txais thiab kev sib txuas lus. Cov kev teeb tsa ib txwm muaj xws li lub zos touchscreen HMI, lub zog saib xyuas zoo, software tsom xam lub zog, thiab cov chaw taws teeb sib txuas lus.
Qhov no txhais tau tias koj tsis tas yuav mus rau qhov chaw kom paub los ntawm koj lub xov tooj ntawm tes lossis khoos phis tawj seb lub zog tsim hluav taws xob zoo li qub, seb qhov ntsuas kub ntawm lub Circuit Court puas txawv txav, thiab siv hluav taws xob ntau npaum li cas rau lub hlis no piv rau lub hli dhau los.
Tshwj xeeb tshaj yog rau kev faib cov photovoltaic lossis tej thaj chaw deb cua ua liaj ua teb, kev saib xyuas tej thaj chaw deb tuaj yeem txo cov nqi O&M. Qee lub tshuab ntse tseem tuaj yeem tshaj tawm cov lus ceeb toom ntxov 72 teev ua ntej kev ua tsis tiav, tiv thaiv cov teeb meem tiag tiag ua ntej lawv tshwm sim.
Qib plaub: daim ntawv pov thawj thiab cov ntawv xeem yuav tsum tau them rau
Lub xeev tau teev tseg tias txhua qhov siab thiab qis voltage ua tiav cov txheej txheem hloov pauv yuav tsum dhau tag nrho cov kev sim hauv lub teb chaws lees paub lub chaw soj nstuam ua ntej tawm hauv lub Hoobkas, suav nrog qhov kub thiab txias, luv Circuit Court, lub neej txhua yam thiab kaum ob ntawm lwm yam khoom.
Tsis tas li ntawd, qhov tseem ceeb yog muab rau cov khoom lag luam uas tau dhau ISO 9001 kev tswj hwm kev ua haujlwm zoo thiab ISO 14001 ib puag ncig kev tswj hwm daim ntawv pov thawj. Yog tias qhov project cuam tshuam nrog kab sib txuas, nws tseem yuav tsum tau lees paub tias cov cuab yeej puas suav nrog hauv cov npe ntawm cov khoom tsim nyog ntawm State Grid lossis cov tuam txhab hluav taws xob hauv zos. export tej yaam num yuav tsum tau xyuam xim rau cov ntawv pov thawj thoob ntiaj teb xws li CE thiab UL.
Kev xaiv cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob yog ib txoj haujlwm ua haujlwm, uas yuav tsum tau ua tib zoo xav txog qhov project nplai, kev ua haujlwm ib puag ncig, qib automation thiab ntev - lub sijhawm ua haujlwm thiab kev saib xyuas.
Ib txheej ntawm high-voltage switchgear feem ntau yuav tsum tau nyob rau hauv kev pab cuam rau ntau tshaj 15 xyoo, thiab ib zaug ntsia, nws yuav luag tag rau lub hwj chim chaw nres tsheb rau lub neej. Yog li ntawd, es tsis txhob tawm tsam nrog ob peb puas duas las pheej yig dua, siv sij hawm me ntsis ntxiv los saib qhov kev ntseeg siab, scalability, thiab kev pab txhawb nqa ntawm cov khoom.
Kev xaiv tsim nyog tuaj yeem tsis tsuas yog txhim kho kev lag luam kev ntseeg siab ntawm lub chaw nres tsheb fais fab, tab sis kuj txo tus nqi ntawm tag nrho lub neej voj voog, thiab muab kev txhawb zog rau lub sijhawm ntev - cov nyiaj tau los ruaj khov ntawm qhov project.
