Qhov sib txawv ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob hloov hluav taws xob feem ntau yog tshwm sim hauv lawv cov ntawv thov scenarios thiab qhov chaw ua haujlwm. Distribution transformers belongs rau ib pawg tshwj xeeb nyob rau hauv cov chav kawm dav ntawm lub hwj chim transformers, nplooj siab rau qhov kawg ntawm kev faib khoom.

Qhov ntauncej-mounted transformerslos yog lub thawv- hom substations pom nyob rau hauv ib puag ncig cov neeg nyob ib puag ncig feem ntau poob rau hauv kev faib khoom transformers. Lawv lub luag haujlwm tseem ceeb yog lub davhlau ya nyob twg voltage hloov pauv ntawm 10kV rau 400V. Xws li transformers feem ntau muaj peev xwm ntawm 30kVA txog 2500kVA. Raws li kev tsim qauv, lawv feem ntau muaj qhov ua tiav tag nrho -cov roj kaw- raus tsim nrog cov fins cua txias ncaj qha rau huab cua.

 

Fais fab hloov hluav taws xob feem ntau yog siv rau loj- lub zog xa hluav taws xob thiab kev hloov pauv thoob plaws thaj chaw dav xws li kev lag luam loj, nroog, thiab thaj chaw nyob deb nroog. Distribution transformers, piv txwv li, feem ntau yog ua haujlwm rau hluav taws xob thiab kev faib tawm hauv nroog me me lossis nyob deb nroog, xws li thaj chaw nyob, factories, mines, cov tsev lag luam, thiab kev cob qhia kev lag luam.

 

Lub tswv yim ntawm lub hwj chim transformers yog dav, encompassing voltage conversion khoom siv nyob rau hauv tag nrho cov theem ntawm lub hwj chim tiam, kis tau tus mob, thiab tis. Ntawm qhov hluav taws xob ntawm cov chaw tsim hluav taws xob loj, ib tus tuaj yeem pom cov hloov pauv loj heev uas muaj peev xwm tshaj 100 MVA. Cov koog no yog lub luag haujlwm rau nce lub tshuab hluav taws xob tso zis hluav taws xob ntawm 10-20kV rau ultra-high voltages ntawm 500kV thiab siab dua. Transformers nyob rau hauv UHV converter chaw nres tsheb tej zaum yuav txawm siv cais- hom qauv, qhov twg ib tug bushing yuav hnyav txog li 8 tons, yuav tsum tau tshwj xeeb tsim los tiv thaiv kev co platforms.

 

Los ntawm ib tug technical parameter foundations:

• Distribution transformers yuav tsum ua raws li GB20052 tus qauv rau tsis muaj -load poob, uas ua rau qhov poob txhua hnub ntawm kwv yees li 0.5-2.5 kW. Piv txwv li, ib qho tshwj xeeb 1000kVA tis transformer qauv muaj nws luv luv -circuit impedance tswj ntawm 4%-6% hloov mus rau luv luv-circuit tam sim no yam ntxwv ntawm kev faib network.
• Fais fab transformers sib txawv heev raws li daim ntawv thov scenarios. Lub 750kV lub ntsiab transformer yuav muaj luv luv -circuit impedance mus txog 14%, nrog windings txais ib tug interleaved disc qauv los tiv thaiv high voltage kev nyuaj siab.

 

Hais txog kev ua haujlwm ib puag ncig:

• Distribution transformers yuav tsum tau tiv taus cov xwm txheej hnyav. Piv txwv li, cov khoom siv hluav taws xob xa tawm hauv lub nplhaib tseem ceeb hauv lub nroog ntug dej hiav txwv yuav tshwj xeeb siv Dyn11 vector pawg thiab tau nruab nrog cov dej noo- pov thawj breathers los tawm tsam ntsev tsuag corrosion.
• Fais fab transformer kev khiav hauj lwm ib puag ncig yog tus tswj ntau dua tab sis yuav tsum tau xav txog tshwj xeeb. Piv txwv li, 220kV lub ntsiab hloov pauv uas txhawb nqa cua ua liaj ua teb hauv Northwest Tuam Tshoj yuav raug teeb tsa nrog cov xuab zeb- plua plav pom tshuab thiab seismic dampers.

 

Txoj kev tu kom muaj qhov sib txawv tseem ceeb. Distribution transformers feem ntau txais kev saib xyuas -dawb tsim, tsuas yog yuav tsum tau ntsuas kub txhua hnub nrog cov ntsuas kub infrared. Piv txwv li, ib qho qhuav- hom faib transformer nyob rau hauv ib qho chaw ua lag luam ua haujlwm tsis tu ncua rau 7 xyoo yam tsis muaj kev tshuaj xyuas tseem ceeb. Fais fab transformer tu yuav tsum nruj; Lub ntsiab transformers ntawm 500kV substations yuav tsum tau soj ntsuam cov roj chromatography txhua 6 xyoo thiab teem caij tu ncua txhua 12 xyoo, koom nrog ntau tshaj kaum kev tshuaj xyuas tshwj xeeb nrog rau bushing dielectric poob xeem thiab winding deformation nrhiav kom tau.

 

Hais txog tus nqi, zoo ib yam li - cov khoom ntsuas ntsuas tuaj yeem sib txawv ntawm tus nqi los ntawm kaum tawm zaus. Ib qho 1000kVA roj-raug faib transformer muaj tus nqi lag luam kwv yees li 120,000 ¥, thaum lub 220kV fais fab transformer ntawm qhov sib npaug muaj peev xwm tshaj ¥ 3,000,000 hauv tus nqi yuav khoom. Qhov kev tsis sib xws no tshwm sim los ntawm cov khoom siv rwb thaiv tsev sib txawv: cov khoom siv hluav taws xob faib hluav taws xob siv 0.3mm tus qauv tooj liab xaim rau siab -voltage windings, whereas ultra- siab-voltage transformers ntiav transposed conductors qhwv nrog 4mm rwb thaiv tsev ntawv.

 

Hla- cov xwm txheej ua haujlwm muaj nyob hauv cov ntawv thov siv tau. Lub 24-pulse rectifier transformer ntawm Shenzhen metro chaw nres tsheb belongs rau pawg fais fab transformer thaum ib txhij ua 1500V DC faib ua haujlwm. Xws li cov transformers tshwj xeeb siv cov qauv peb-winding, ua kom muaj kev sib haum xeeb los ntawm kev hloov kho theem, thiab suav nrog cov yam ntxwv ntawm ob hom transformer.

 

Kev xaiv cov cuab yeej yuav tsum tau txiav txim siab thawj zaug ntawm daim ntawv thov scenarios. Kev faib hluav taws xob nyob hauv qhov tseem ceeb S13 lub zog- cov khoom siv hluav taws xob tau zoo, uas tsis muaj -load poob yog 30% qis dua cov qauv qub. Rau photovoltaic cog daim phiaj-kev sib txuas scenarios, ob npaug -split winding fais fab transformers yuav tsum tau xaiv, ua rau ob qho tib si 35kV kauj ruam- nce thiab kev sib cais ntawm cov khoom sib txawv. Lub tuam txhab biopharmaceutical ntiav ua haujlwm ntawm -load kais- hloov pauv hloov pauv nrog ± 5% qhov hloov pauv voltage kom paub meej lub zog muab khoom zoo rau cov cuab yeej precision.
