Aluminium vs Copper Coils rau Distribution Transformers

Aluminium vs Copper Coils rau Distribution Transformers

Sim txiav txim siab ntawm tooj liab thiab txhuas coils rau koj qhov project transformer? Peb rhuav tshem lub zog kev ua tau zoo, tag nrho cov nuj nqis, chav tsev loj, txhua yam robustness thiab kev pab cuam ntev los pab koj xaiv cov khoom siv winding zoo rau koj cov kev xav tau ua haujlwm.

Xa lus nug tam sim no

Tau ntau xyoo lawm, tooj liab tau suav tias yog qhov kev xaiv zoo rau kev hloov pauv windings. Tab sis rau peb caug xyoo dhau los tam sim no, txhuas tau dhau los ua qhov kev xaiv tseem ceeb. Qhov no tsis yog los ntawm kev huam yuaj. Niaj hnub nimno aluminium-mob tis transformers tau ua pov thawj tias tsuas yog txhim khu kev qha, ua haujlwm tau zoo, thiab ruaj khov raws li lawv cov khoom siv tooj liab hauv qhov tiag - kev pabcuam hauv ntiaj teb.

Qhov ntawd tsis txhais hais tias tooj liab yog qhov kev xaiv tsis raug. Qhov tseeb, hauv qee qhov kev siv, tooj liab ua rau kev nkag siab ntau dua. Rau cov chav kawm fais fab substation transformers, tooj liab yog mus - rau kev xaiv. Tab sis rau feem ntau kev lag luam thiab kev lag luampad mounted transformers, qhuav - hom transformers, thiabsubstation transformers, aluminium tsis yog kev sib haum xeeb. Nws yog feem ntau siv tau.

Kev ua tau zoo ntawm lub zog yog ib qho tseem ceeb tshaj plaws los ntsuas thaum xaiv cov khoom siv raw rau transformer windings.

Txhua lub tshuab hluav taws xob tam sim no, txawm tias haum nrog tooj liab lossis txhuas coils, yog tsim los ua raws li cov cai DOE zoo tib yam. Raws li ib qho piv txwv, cov cai hauv zos tswj hwm tag nrho 500 kVA peb-theem ua kua-immersed ncoo-mounted transformers ua tau zoo ntawm 99.35%, tsis muaj qhov sib txawv raws li cov hlau winding.

Aluminium tsuas yog nyob ib ncig ntawm 60 feem pua ​​​​ntawm tooj liab cov hluav taws xob conductivity. Txhawm rau tiv thaiv qhov kev tsis txaus no, cov neeg tsim khoom nthuav dav tus ntoo khaub lig- ntu ntawm aluminium conductors, ntsuas lub zog poob qib kom phim cov tooj liab windings.

Copper tej zaum yuav raug xaiv nyob rau hauv tej yaam num xav tau kev ua tau zoo tshaj DOE efficiency thresholds los yog ultra- nruj tsis txwv. Txawm li cas los xij, qhov uas twb muaj lawm DOE 2016 specifications teem unified efficiency benchmarks rau tag nrho cov transformers nyob rau hauv qab no 2,500 kVA. Yog li ntawd, transformers ua nrog cov khoom siv winding xa ze li qhov sib npaug ntawm lub zog ua haujlwm.

Coil Dimensions

Thaum ua ib qho kev hloov pauv hloov pauv rau cov qauv kev laus, nws tib yam - hloov peev xwm yuav ua rau muaj qhov loj dua tag nrho. Qhov kev hloov pauv no feem ntau yog los ntawm xyoo 2010- tso tawm DOE lub zog ua haujlwm tau zoo. Rau retrofit tej yaam num txwv los ntawm kev txwv qhov chaw installation, tooj liab windings nthuav tawm cov kev daws teeb meem ua tsaug rau lawv cov geometry ntau compact. Cov tooj liab me me tuaj yeem txiav me ntsis qhov ntev ntawm lub tank transformer, txawm hais tias qhov kev daws teeb meem no poob rau hauv kev cai - engineering designs. Txawm tias muaj cov nuj nqis ntxiv rau lub tshuab hloov pauv hloov pauv, tus nqi tuaj yeem raug cuam tshuam los ntawm kev zam tag nrho cov txheej txheem ntawm koj qhov kev teeb tsa uas twb muaj lawm.

Transformer Tank Footprint

Transformer cov chaw muag khoom feem ntau tau txais cov qauv tsim cov tsev nyob hauv lub tank raws li tus qauv tsim. Yog li ntawd, xaiv tooj liab coil configurations yuav tsis cia li yield ib tug ntau compact transformer. Cov neeg tsim khoom feem ntau xa cov khoom sib xws rau cov tooj liab thiab txhuas qhov txhab sib txawv. Yog tias qhov txo qis hauv chav tsev qhov chaw hauv pem teb yog qhov tseem ceeb tshaj plaws, kom meej meej qhia qhov yuav tsum tau ua rau koj tus neeg muag khoom ua ntej, raws li kev cai - qhov loj ntawm lub tank yuav tsim nyog.

Txawm hais tias nrog cov coils ntawm qhov sib npaug, aluminium thiab tooj liab windings tsim cov hloov pauv nrog qhov hnyav sib txawv. Tooj liab khav theeb ntau dua, ua rau tooj liab -tshuaj hloov pauv uas hnyav kwv yees li 20 feem pua ​​​​ntau tshaj lawv cov khoom siv txhuas. Rau cov transformers mounted rau lub ru tsev los yog tsa platforms, qhov no ntxiv loj coj ntxiv cov nuj nqis thiab stricter structural xav tau kev pab.

Ntawm qhov tod tes, tooj liab-mob transformers tseem yog qhov kev xaiv zoo tshaj rau cov haujlwm uas qhov loj me me ua ntej tshaj qhov hnyav tag nrho.

Tooj liab hais kom tus nqi raw khoom ntau dua thiab nthuav tawm ntau dua tus nqi hloov pauv piv rau txhuas. Yog li ntawd, transformers ua nrog tooj liab windings feem ntau nqa tus nqi tag ob mus rau peb npaug ntawm txhuas- qhov sib npaug. Rau cov neeg muas zaub ntau yam transformers nyob rau hauv ntau yam dej num, no loj heev upfront nqi sib txawv accumulates sai heev.

Uas tau hais tias, tooj liab coils xa cov khoom siv hluav taws xob zoo tshaj plaws, uas txhais tau tias txo qis cov nqi ua haujlwm tsis tu ncua ntawm cov cuab yeej siv lub neej. Thaum lub tshuab hloov hluav taws xob tau tsim los ua kom dhau DOE cov txiaj ntsig kev ua tau zoo, qhov kev sib tw ntev - lub sij hawm txuag ntawm cov nqi khiav yuav ua tau ntau heev. Txawm li cas los xij, peb cov kev suav suav qhia tias nws yuav siv sijhawm ntau xyoo los cuam tshuam tus nqi pib qhov sib txawv ntawm ob hom winding. Ob qho luv luv- kev siv sijhawm ntev thiab ntev- kev txuag nyiaj ua haujlwm yuav tsum tau ntsuas kom zoo thaum xaiv cov khoom.

Lub zog tensile yog cov khoom siv tiv thaiv kom raug rub tawm. Yeej, nws nyuaj npaum li cas. Copper lub zog tensile siab ua rau nws zoo tagnrho rau cov transformers loj.

Cov fais fab loj dua tuaj yeem pom cov dej ntws nrawm dua thiab luv luv - lub zog hluav taws xob. Cov zog tam sim no siab no yuav ua rau qee qhov kev txav mus los hauv cov windings. Vim li no, tooj liab yog qhov kev xaiv zoo tshaj plaws rau lub zog loj dua transformers. Cov tooj liab coils ntawm cov chav loj loj no feem ntau raug mob hauv ib lub voj voog disc tsim. Lub disc tsim txhawb cov coils tiv thaiv lub zog luv luv luv. Aluminium yuav tsum tau nqa lub rooj zaum rov qab rau tooj liab ntawm no, txhua zaus.

Tab sis, feem ntau me me padmounts thiab substations tsis siv disc coils. Lawv siv cov qauv duab plaub nrog daim ntawv -mob qhov hluav taws xob qis qis. Tsis tas li ntawd, high voltage windings yog txheej rau saum cov ntawv windings.

Cov qauv duab plaub no pab txo qis - Circuit Court quab yuam ntawm windings. Mechanical stress tau kis mus rau tag nrho cov nto ntawm winding. Nyob rau hauv lem, qhov no minimizes lub luag hauj lwm ntawm tus neeg xyuas pib lub tensile lub zog. Txawm li cas los xij, qhov kev tsim no dhau los ua tsis tau zoo ntawm kev ntsuas qhov loj dua transformer.

Tab sis, nws yog qhov kev xaiv zoo tshaj plaws hauv qhov chaw faib khoom. Feem ntau ntawm kev lag luam thiab kev lag luam peb - cov ntawv thov theem qis dua 5MVA siv cov duab plaub. Nyob rau hauv no arena, tooj liab thiab txhuas yog nyob rau tib lub chaw ua si.
