Qhov no yog ib txoj haujlwm tsim hluav taws xob rau tsoomfwv lub tsev ua haujlwm. Txij li thaum tus neeg yuav khoom lub zog-Txuag kev ntsuas ntsuas ntsuas nruj thiab tus qauv tsim kuj yuav tsum xav txog kev ua haujlwm thiab kev saib xyuas cov nqi ntawm lub tsev tom qab ua tiav lub tsev, dealim tau ua ib qho kev ntsuam xyuas ntawm lub zog load ntawm nws cov substation qis-voltage system thiab dhau qhov kev siv hluav taws xob siv hluav taws xob zoo (TOC method) piv rau cov qauv siv.Peb Theem Epoxy-resin Qhuav- hom TransformerthiabS(B)H15-M Series Sealed Amorphous Alloy Transformereconomic ntsuas ntsuas raws li lub hauv paus rau kev xaiv tom ntej ntawm transformers.

 

Kev Siv Hluav Taws Xob thiab Tsawg -voltage Main Wiring

Qhov project no muaj 22/0.4kV ywj siab substation. Cov neeg tsim kho yog lub luag haujlwm los qhia ob qho kev ywj pheej 22kV nruab nrab voltage sab nraud kab faus rau hauv nruab nrab voltage faib chav.

 

Ob qhov qhuav- hom transformers tau nruab rau hauv lub chaw nres tsheb kom ua haujlwm hauv series, txhua qhov muaj 50% load thaum lub sijhawm ua haujlwm ib txwm, thiab thaum ib qho khoom siv fais fab tsis ua haujlwm, lwm qhov nrog tag nrho cov load.

 

Raws li kev ruaj ntseg ntawm lub zog hluav taws xob hauv zos thiab cov kev xav tau ntawm cov tog neeg txawv teb chaws, ob lub tshuab hluav taws xob diesel uas muaj lub zog sib xws ntawm 1 000kVA raug teeb tsa ua ke los ua lub zog thaub qab los muab kev tiv thaiv tag nrho lub zog tiv thaiv rau qhov project thaum muaj lub hauv paus tsis ua haujlwm.

 

Txhua qhov hluav taws kub- cov khoom siv sib ntaus sib tua, tshaj tawm xov xwm thiab lub rooj sib tham, khoom siv kev ruaj ntseg, teeb pom kev kub ceev, hluav taws xob hauv chaw ua haujlwm, elevators, tsis muaj zog tam sim no hauv computer chav, relay fais fab mov, lub twj tso kua mis lub neej, thiab cov kav dej phwj tuaj yog qhov tseem ceeb ntawm qhov project no. Ntawm lawv, lub auditorium thiab chaw txais tos teeb pom kev zoo, hluav taws xob siv hluav taws xob rau lub suab, yees duab thiab tshuab computer yog qhov tseem ceeb tshwj xeeb ntawm cov thawj - theem loads; kev siv hluav taws xob rau huab cua- cua txias yog qhov thib ob - theem load; thiab cov dej ntws thiab cov teeb pom kev zoo toj roob hauv pes yog qhov thib peb - theem loads. Daim duab schematic ntawm qhov qis -voltage main wiring scheme of this project is displayed in Figure 1.

Active economic load tus nqi piv

Raws li kev txheeb xyuas ntawm Daelim's transformer technical parameters, active economic load npaum li cas thiab tseem ceeb load npaum li cas ntawm peb theem Epoxy-resin qhuav-hom Transformer thiab S(B)H15-M Series Sealed Amorphous Alloy Transformer muaj nyob rau hauv Table 4 thiab Table 5.

Peb Theem Epoxy-resin Qhuav-hom Transformer technical parameters thiab economic load npaum li cas

S(B)H15-M Series Sealed Amorphous Alloy Transformer technical parameters thiab economic load npaum li cas

Los ntawm cov txiaj ntsig ntawm kev suav saum toj no, nws tuaj yeem pom tau tias SCB10 epoxy resin cam khwb cia peb -theem qhuav- hom transformer nrog lub peev xwm ntawm 1 600kVA muaj qhov ua haujlwm siab tshaj plaws thaum lub zog ntawm kev lag luam load yog 46%, thiab qhov tseem ceeb load tus nqi yog 21% thaum nws nyob rau hauv qis qis ntawm thaj tsam kev lag luam.

 

SCBH15 qis- poob amorphous alloy transformer nrog lub peev xwm ntawm 1 600kVA muaj qhov ua haujlwm siab tshaj plaws thaum lub zog ntawm kev lag luam load yog 25%, thiab nws qhov tseem ceeb load tus nqi yog 6% thaum nws nyob rau hauv qis qis ntawm thaj tsam kev lag luam.

 

Nyob rau hauv xyoo tas los no, ntau yam ntawm qis- poob lub zog hloov pauv tau siv dav, thiab cov txiaj ntsig kev lag luam tseem ceeb tau ua tiav raws li kev txuag hluav taws xob thiab cov nqi khiav lag luam.

 

Tam sim no, qhov ntsuas kev ua haujlwm ntawm lub transformer nws tus kheej yog twb siab heev. Feem ntau, qhov ntsuas qhov ua tau zoo ntawm cov khoom me me thiab nruab nrab - loj transformers yog siab dua 96%.

 

Txawm li cas los xij, nyob rau hauv ntau zaus, qhov kev ua haujlwm tiag tiag ntawm lub tshuab hloov pauv tsis siab vim yog qhov tsis tsim nyog thiab kev ua haujlwm ntawm lub transformer.

 

Thaum lub load yam ntawm lub transformer tsawg dhau los yog siab dhau lawm, qhov kev faib ua feem ntawm tag nrho cov kev siv ntawm lub transformer nws tus kheej nyob rau hauv tag nrho cov input zog ntawm lub transformer nce, uas ua rau ib tug txo nyob rau hauv qhov tseeb kev khiav hauj lwm efficiency.

 

Kev cuam tshuam los ntawm kev coj cwj pwm yav dhau los, ntau tus neeg tsim qauv thiab kos duab tshuaj xyuas tseem muaj qee qhov kev nkag siab tsis zoo hauv kev xaiv thiab kev ua haujlwm ntawm transformers, uas ua rau muaj ntau lub zog pov tseg hauv kev siv cov tswv yim ntawm transformers.

 

Piv txwv li, qhov ua tau zoo tshaj plaws ntawm lub tshuab hloov pauv tau tshwm sim ntawm kwv yees li 75% tus nqi thauj khoom, thiab tus nqi hloov pauv yog tsawg dua 30%. Tsis muaj lub hauv paus rau kev suav. Nws tuaj yeem pom los ntawm cov saum toj no hais tias cov kev lag luam muaj zog load tus nqi thiab kev thuam ntawm transformers ntawm txawv series thiab txawv tsis Qhov load factor qhov tseem ceeb kuj txawv.

 

Yog li ntawd, rau ob 1 600kVA transformers ntsia hauv qhov project no, tus nqi thauj khoom yog 43% rau 46% thaum lub sijhawm ua haujlwm ib txwm, thiab tus nqi thauj khoom yog 94% thaum lub sijhawm ua haujlwm txhaum. 6%, kev xaiv yog tsim nyog.

 

Kev sib piv ntawm kev siv hluav taws xob zoo siv hluav taws xob

Raws li cov txheej txheem kev siv hluav taws xob siv hluav taws xob zoo (TOC txoj kev) tau qhia saum toj no, Daelim siv lub neej ua haujlwm hloov pauv mus rau 10 xyoo thiab 20 xyoo los xam cov nqi hluav taws xob poob uas lub transformer yuav them thaum lub sijhawm siv nyiaj txiag, thiab xav txog nws cov peev txheej pib. Los ntawm kev xav txog kev lag luam, nkag siab thiab ntsuas lub zog-txuag cov txiaj ntsig ntawm transformers ntau yam kev tshawb fawb.

 

Thaum ua tib zoo mloog rau lub zog-txuag cov txiaj ntsig, qhov project no tseem ua tib zoo saib xyuas qhov ua tau thiab yooj yim ntawm kev ua haujlwm ntev - lub sij hawm cog lus rau kev tu txhua hnub thiab kev kho dua tshiab ntawm cov cuab yeej loj.

 

Nws tuaj yeem pom los ntawm Table 6 tias raws li tus nqi thauj khoom ntawm qhov project no thaum lub sijhawm ua haujlwm ib txwm muaj, tus nqi thauj khoom yog 46%. Kev txheeb xyuas kev siv hluav taws xob zoo: S(B)H15-M Series Sealed Amorphous Alloy Transformer muaj tus nqi siv hluav taws xob zoo ntawm 1 159 274 thaum lub sijhawm 10- xyoo kev siv nyiaj txiag. RMB, 14% siab dua qhov feem ntau siv Peb Theem Epoxy-resin Qhuav-hom Transformer.

 

Tus nqi siv hluav taws xob zoo tshaj plaws nyob rau lub sijhawm 20- xyoo kev siv nyiaj txiag yog 1 251 557 RMB, uas yog siab dua li feem ntau siv Peb Phase Epoxy-resin Dry-type Transformer. 2. 4%.

 

S(B)H15-M Series Sealed Amorphous Alloy Transformer muaj qhov poob qis thiab lub zog tseem ceeb- txuag cov nyhuv. Qhov ntsuas tsis muaj-load poob tsuas yog li 30% ntawm Peb Theem Epoxy-resin Qhuav hom Transformer.

 

Kev sib piv cov lus ntawm kev siv hluav taws xob hluav taws xob zoo ntawm transformers

Qhov ntsuas tsis muaj-load poob tsuas yog kwv yees li 30% ntawm Peb Phase Epoxy-resin Qhuav- hom Transformer.

 

Yog tias qhov kev nqis peev thawj zaug tsis quav ntsej, tus nqi khiav lag luam ntawm S(B)H15-M Series Sealed Amorphous Alloy Transformer thaum lub sijhawm 10- xyoo kev lag luam siv yog 7% qis dua qhov feem ntau siv Peb Theem Epoxy- cob Qhuav - hom Transformer, thiab nyob rau hauv lub sij hawm siv nyiaj txiag tsawg dua 20% Phase Epoxy-resin Qhuav hom Transformer.

 

Raws li qhov project nyob rau hauv cov teb chaws Es Xias Qab Teb, cov khoom loj - cov khoom siv hluav taws xob faib hluav taws xob ntawm cov teb chaws tau txais kev lag luam feem ntau yog yuav los ntawm cov teb chaws tsim kho thiab Tuam Tshoj. Kev saib xyuas niaj hnub tuaj yeem ua tau los ntawm lawv tus kheej, tab sis kev kho dua tshiab yuav tsum tau xa cov kws tshaj lij thiab cov kws tshaj lij los ntawm cov saum toj no - hais txog cov chaw tu lub tebchaws.

 

Yog li ntawd, tsis muaj qhov sib txawv ntawm qhov yooj yim ntawm kev saib xyuas thaum xaiv cov cuab yeej loj, thiab tsis muaj qhov cuam tshuam hauv cheeb tsam thaum xaiv S(B)H15-M Series Sealed Amorphous Alloy Transformer.

 

Yog li thaum kawg Daelim pom zoo kom siv S(B)H15-M Series Sealed Amorphous Alloy Transformer rau cov neeg siv khoom.

Thaum koj xav nrhiav ntau dua li cov transformers uas twb muaj lawm, Daelim's Transformer Service Center tuaj yeem pab koj tsim thiab tsim cov transformers uas tau raws li koj cov kev xav tau tshwj xeeb.
