Distribution Transformer: Cov Khoom Txhais, Cov Txheej Txheem Xaiv & Cov Txheej Txheem Txhim Kho Cov Txheej Txheem
1. Cov Lus Txhais & Cov Ntawv Thov Kev Siv Yooj Yim
Distribution transformers yog cov cuab yeej tseem ceeb hauv cov khoom siv hluav taws xob thiab kev faib hluav taws xob ntawm kev lag luam thiab kev lag luam mining, pej xeem vaj tse thiab hauv nroog fais fab. Feem ntau, lawv nqis los ntawm cov kab hluav taws xob siab ntawm 10kV, 6kV lossis 35kV rau tus qauv 230/400V qis-voltage bus voltage rau kawg- neeg siv hluav taws xob noj.
Qhov no series ntawm transformers muaj feem xyuam rau AC 50Hz / 60Hzpeb -theem fais fab faibn cov xwm txheej, nrog rau qhov siab tshaj peb -theem ntsuas qhov muaj peev xwm ntawm 2500kVA thiab qhov siab tshaj plaws ib zaug -theem ntsuas qhov muaj peev xwm ntawm 833kVA. Hauv cov phiaj xwm kev faib hluav taws xob zoo ib yam, ib zaug -theem transformers tsis pom zoo rau cov ntawv thov tseem ceeb vim tias tsis muaj kev txwv kev ua haujlwm tsis sib npaug.
2. Transformer Quantity & Tshwj Xeeb Scenario Txoj Cai Xaiv
Txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob txuas ntxiv thiab kev ua haujlwm ruaj khov rau cov khoom tseem ceeb, transformer kom muaj nuj nqis thiab kev teeb tsa chav tsev yuav tsum ua raws li cov qauv tsim qauv rau cov yam ntxwv sib txawv:
Ntau Transformers rau thawj thiab theem nrab Loads
Rau tej yaam num uas loj -scale thawj thiab theem nrab fais fab loads, nws raug nquahu kom teeb tsa ob los yog ntau dua transformers. Nyob rau hauv qhov kev tshwm sim ntawm ib qho kev hloov pauv ib zaug lossis kev saib xyuas, qhov seem ua haujlwm hloov pauv yuav tsum muaj peev xwm txaus los ua kom tag nrho cov kev xav tau ntawm lub hauv paus thiab theem nrab load zog. Lub caij no, thawj thiab theem nrab loads yuav tsum tau teem lub hauv paus kom ntau li ntau tau kom tsis txhob overly dispersed hwj chim noj, uas yuav ua rau unbalanced load lag luam thiab txo hwj chim mov efficiency.
Dedicated Transformers rau lub caij Loads
Kev ywj pheej tshwj xeeb transformers raug pom zoo rau cov xwm txheej uas muaj lub caij nyoog hloov pauv lub caij nyoog. Cov ntawv thov muaj xws li hauv nruab nrab huab cua- cua txias loads tub yees thiab hluav taws xob cua sov loads nyob rau hauv loj coj mus muag thiab pej xeem vaj tse, zam lub caij nyoog load peaks cuam tshuam rau kev ruaj ntseg ntawm cov pa hluav taws xob faib systems.
Dedicated Transformers rau Concentrated Heavy Loads
Rau cov xwm txheej ntau lawm nrog cov kev cuam tshuam loj loj, kev hloov pauv tshwj xeeb yuav tsum tau teeb tsa kom haum rau kev ua haujlwm tshwj xeeb. Cov cuab yeej siv sib txuam nrog qhov yuav tsum tau muaj xws li siab- cov cuab yeej siv hluav taws xob cua sov, muaj X- cov tshuab hluav taws xob, hluav taws xob arc rauv thiab lwm yam hnyav- thauj khoom muaj chaw, ua kom muaj kev cuam tshuam cov loads thiab tiv thaiv cov kab hluav taws xob loj.
Independent Transformers rau teeb pom kev zoo Loads
Nyob rau hauv feem ntau cov xwm txheej, lub zog thiab teeb pom kev zoo tuaj yeem sib koom ua ke hloov pauv hloov pauv. Txawm li cas los xij, rau cov haujlwm uas muaj ultra- teeb pom kev loj loj lossis cov xwm txheej uas ua haujlwm sib xyaw ua rau lub teeb pom kev zoo tsis zoo thiab ua rau lub neej luv luv, kev ywj pheej teeb pom kev zoo hloov pauv tau txais los ua kom ruaj khov hluav taws xob zoo thiab txhim kho lub zog siv hluav taws xob.
3. Kev xaiv Transformer Raws li kev ua haujlwm ib puag ncig
Qhov sib txawv ntawm - thaj chaw ib puag ncig txiav txim siab hom, qib kev tiv thaiv thiab kev teeb tsa ntawm cov khoom siv hluav taws xob faib hluav taws xob, ua raws li cov qauv tsim hluav taws xob hauv teb chaws thiab thoob ntiaj teb:
Ib puag ncig zoo li qub
Rau cov qauv ib puag ncig xws li cov chaw tsim khoom thiab mining, kev ua liaj ua teb kev txhawb nqa substations thiab lub zej zog ywj pheej faib chaw, ob qho tib si roj -immersed thiab qhuav- hom transformers yog xaiv tau. Cov qauv tseem ceeb tau pom zoo suav nrog S8, S9, S10 roj-immersed transformers thiab SC(B)9, SC(B)10 qhuav-hom transformers, uas muaj kev ua haujlwm ruaj khov thiab tus nqi-kev ua tau zoo rau cov kev xav tau ntawm cov khoom siv hluav taws xob.
Siab-Rise & Ntau-Zaj Tsev Ib puag ncig
Rau cov chav faib hluav taws xob hauv ntau- zaj dab neeg lossis siab - nce toj hauv pej xeem vaj tse, kev nyab xeeb hluav taws yog qhov kev txiav txim siab tseem ceeb. Tsuas yog tsis yog -combustible thiab nplaim taws-retardant qhuav- hom transformers raug tso cai. Cov qauv nyiam muaj xws li SC(B)9, SC(B)10, SCZ(B)9 thiab SCZ(B)10 series nplaim taws-retardant qhuav- hom transformers kom tshem tawm cov hluav taws kub nyhiab ntawm cov roj hluav taws xob insulating.
Dusty & Corrosive Ib puag ncig
Nyob rau hauv cov chaw ua lag luam nrog cov plua plav loj heev, cov pa roj corrosive thiab cov pa phem, tag nrho cov ntaub ntawv kaw los yog kaw cov hloov pauv yuav tsum raug xaiv los tiv thaiv kev laus hauv cov rwb thaiv tsev thiab tiv thaiv corrosion. Cov qauv siv tau suav nrog BS9, S9 kaw hom, S10 kaw hom thiab SH12-M tag nrho cov hloov pauv hloov pauv, hloov mus rau qhov hnyav ntawm ib puag ncig kev lag luam.
Integrated Installation nyob rau hauv Distribution Room
Cov kua dej-dawb thiab tsis yog- roj- immersed transformers tuaj yeem ntsia tau rau hauv tib chav nrog cov khoom siv hluav taws xob siab thiab qis. Txhawm rau ua kom tau raws li cov qauv kev nyab xeeb, cov hloov pauv no yuav tsum tau nruab nrog IP2X tus qauv tiv thaiv cov ntaub thaiv kom tsis txhob muaj kev sib cuag thiab ua kom muaj kev nyab xeeb ntawm - chaw ua haujlwm.
4. Transformer Capacity xaiv raws li lub hwj chim Load
Qhov tsim nyog muaj peev xwm sib piv yog lub hauv paus ntawm kev ua haujlwm zoo thiab kev lag luam transformer, ua raws li cov qauv kev xam pom thiab kev lag luam specification:
Qhov ntsuas muaj peev xwm ntawm cov khoom siv hluav taws xob faib hluav taws xob yuav tsum raug txiav txim siab raws li kev suav suav ntawm cov khoom siv hluav taws xob hauv tsev (cov hluav taws kub- feem ntau tsis suav nrog cov khoom siv hluav taws xob). Lub zog pom meej them nyiaj ua haujlwm yog lub hauv paus kawg rau kev lees paub transformer muaj peev xwm thiab ntau. Qhov zoo tshaj plaws kev khiav hauj lwm load tus nqi ntawm cov pa transformers yog tswj nyob ib ncig ntawm 85%, ua tiav ib tug sib npaug lub xeev ntawm kev ua hauj lwm npaum thiab ntev kev pab cuam lub neej, uas yog dav siv nyob rau hauv ceev ceev kev kwv yees nyob rau hauv engineering tej yaam num.
Hauv kev tsim qauv engineering, kev xaiv muaj peev xwm nruj me ntsis ua raws li cov qauv hauv tebchaws suav nrog GB / T 17468-1998 Cov Lus Qhia rau Kev Xaiv Lub Hwj Chim Fais Fab thiab GB / T 17211-1998 Cov Lus Qhia rau Kev Thauj Khoom ntawm Qhuav Hom Fais Fab Transformers. Ob qhov kev qhia tshwj xeeb muab cov kev pabcuam suav ua haujlwm thiab lub sijhawm thauj khoom nkhaus txoj hauv kev kom paub meej, tus qauv thiab kev tshawb fawb txog kev hloov pauv lub peev xwm.
5. Standard On -Tsev Kawm Ntawv Cov Lus Qhia
Distribution transformers yog cov cuab yeej tseem ceeb ntawm cov tshuab hluav taws xob substation, nrog cov qauv tsim thiab kev sib koom ua ke cov kev qhia tshwj xeeb:
Qhib-thav duab qhuav- hom transformers yam tsis muaj qhov thaiv thaiv yuav tsum tau nruab rau ntawm lub hauv paus ruaj khov nrog cov laj kab tiv thaiv uas tau tsim nyob ib puag ncig cov khoom siv rau kev sib cais kev nyab xeeb. Qhuav- hom transformers nrog cov ntaub ntawv tiv thaiv tiav tuaj yeem raug ntsia ncaj qha rau hauv av. Tag nrho ntawm - qhov chaw tsim kho thiab layout yuav tsum nruj me ntsis hais txog lub teb chaws tus qauv tsim qauv kos duab 03D201-4 10/0.4kV Transformer Room Layout thiabSubstation Conventional Equipment Installation Specifications, kom ntseeg tau cov txheej txheem kev teeb tsa, kev nyab xeeb qhov sib txawv thiab ua raws li kev ua haujlwm ntawm tag nrho cov khoom siv hluav taws xob.
