500kVA Qhuav-Hom Transformers: Copper-Npaj Vs Aluminium-Qhov Mob ?

Rau ib500kVA qhuav- hom transformer, windings yog lub plawv ntawm chav tsev. Lawv ncaj qha cuam tshuam rau hluav taws xob conductivity, thermal tswj, luv luv-circuit withstand peev, thiab ntev -lub sij hawm cia siab rau. Tooj thiab txhuas yog ob qho khoom tseem ceeb, txhua tus muaj qhov zoo sib xws.

• Toojmuaj ntau dua conductivity (58 MS / m vs 35.4 MS / m rau txhuas) thiab superior creep kuj.
• Aluminiumyog sib dua (txog 30% tsawg ntom) thiab feem ntau pheej yig dua. Txawm li cas los xij, qhov kev xaiv "zoo dua" nyob ntawm koj daim ntawv thov tshwj xeeb, thauj khoom profile, thiab pob nyiaj siv. GNEE's engineering team ntsuam xyuas cov xwm txheej no kom pom zoo cov kev daws teeb meem, ua kom ntseeg tau tias kev ua raws li IEC/ANSI thiab muaj teeb meem ntau xyoo- ua haujlwm dawb.

 

Hauv tsab xov xwm no, peb rhuav tshem txhua qhov kev lag luam thiab kev lag luam ntawm500kVA qhuav- hom transformerssiv tooj liab lossis aluminium windings - los ntawm kev poob thiab kub nce mus rau kev teeb tsa hneev taw thiab lub neej - nqi mus ncig. Thaum kawg, koj yuav paub tseeb tias cov khoom siv twg haum rau koj qhov project, thiab vim li cas kev koom tes nrog cov chaw tsim khoom muaj kev paub zoo li GNEE lav qhov zoo thiab tus nqi.

 

 

Ua ntej sib piv kev ua tau zoo, ntawm no yog ib sab - los ntawm - sab kev cov ntaub ntawv rau 500kVA qhuav- hom transformer (11kV/0.4kV, Dyn11, 50/60Hz). Cov nqi yog raws li GNEE cov ntaub ntawv tsim khoom thiab cov qauv thoob ntiaj teb (IEC 60076-11, IEEE C57.12.91).

Tus nqi yog qhov qhia tau; cov ntaub ntawv tiag tiag nyob ntawm chav kawm voltage, qib rwb thaiv tsev, thiab kev tsim kho kom zoo. GNEE muab cov ntawv pov thawj xeem ntawv pov thawj rau txhua chav.

tooj liab windings thiab txhuas windings rau 500kVA qhuav- hom transformers

 

Copper Windings: Higher Conductivity, Me Hneev taw

Ua tsaug rau ntau dua conductivity, tooj liab windings nyob qhov chaw tsawg dua rau tib qhov kev ntsuas tam sim no. Qhov no tso cai rau cov tub ntxhais compact ntau dua -coil los ua ke, txo tag nrho cov transformer qhov ntev los ntawm kwv yees li 10-15% piv rau txhuas tsim. Copper kuj nthuav tawm cov thermal conductivity zoo dua, ua rau txo qhov kub ntawm qhov kub thiab txias dua. Rau tej yaam num uas txwv qhov chaw (xws li, sab hauv tsev substations, cua turbines), ib tug tooj liab-qhov txhab500kVA qhuav- hom transformerfeem ntau nyiam txawm tias tus nqi siab dua.

 

Aluminium Windings: Sib zog thiab nyiaj txiag ntau dua

Aluminium qhov qis qis ua rau cov qauv winding ho sib dua - txog ib nrab ntawm qhov hnyav ntawm tooj liab rau tib lub zog hluav taws xob. Qhov no txo ​​cov nqi shipping thiab yooj yim installation (tsis muaj hnyav nqa iav). Tus nqi qis raw khoom ua rau txhuas-mob transformers 25-35% pheej yig dua pem hauv ntej. Txawm li cas los xij, vim muaj kev tiv thaiv siab dua, ntu ntu yuav tsum loj dua, feem ntau xav tau kev txhawb nqa cov cuab yeej siv zog. Niaj hnub nimno aluminium winding cov txheej txheem (piv txwv li, ntawv ci winding nrog epoxy resin) tau kov yeej kev txhawj xeeb yav dhau los txog kev txiav thiab nkag.

 

 

Thaum ntsuas500kVA qhuav- hom transformers, tiag- ntiaj teb kev ua haujlwm hauv qab yog qhov tseem ceeb. Cia peb txheeb xyuas qhov poob, qhov kub thiab txias, thiab kev ua haujlwm zoo.

Load Losses thiab Efficiency

Copper lub qis resistivity ncaj qha mus rau qis I²R poob. Rau ib chav tsev 500kVA ntawm 80% chaw thau khoom, tooj liab windings tuaj yeem txo qhov poob ntawm 10-15% piv rau qhov sib npaug ntawm cov qauv txhuas. Tshaj li 20-xyoo lub neej, qhov kev ua tau zoo sib txawv no tuaj yeem cuam tshuam qhov kev nqis peev ntau dua, tshwj xeeb tshaj yog rau cov ntawv thov txuas ntxiv (xws li, cov chaw zov me nyuam, cov chaw tsim khoom). Rau kev sib cuam tshuam los yog caij nyoog loads, txhuas tus nqi qis dua yuav zoo dua. GNEE muab cov lej poob raws li koj lub luag haujlwm tshwj xeeb - thov kev tshuaj xyuas tus nqi hluav taws xob dawb los ntawm peb pab neeg.

 

Thermal Management thiab Overload Capacity

Copper's superior thermal conductivity (401 vs 237 W / m·K) tso cai rau cov cua sov sai dua los ntawm cov cua kub kub. Qhov no ua rau muaj qhov sib txawv ntawm qhov kub thiab txias txog li 15% luv dua - lub sijhawm muaj peev xwm dhau. Aluminium-kho hloov pauv feem ntau xav tau cov kav dej txias dua lossis yuam- cua kiv cua kom ua tiav cov thermal ua haujlwm zoo sib xws. Rau qhov chaw hnyav (qhov kub thiab txias, huab cua tsis zoo), tooj liab feem ntau yog qhov kev xaiv zoo dua. GNEE tus tsim software simulates thermal cwj pwm kom ntseeg tau tias Class F lossis H rwb thaiv tsev nyob hauv qhov txwv tsis hais cov khoom siv.

 

 

Raws li ntau txhiab qhov kev teeb tsa, GNEE pom zoo cov lus qhia hauv qab no:
