Dab tsi yog qhov zoo / qhov tsis zoo ntawm kev siv tooj liab vs. aluminium windings hauv transformer?

Aluminium tsis tshua muaj hluav taws xob, yog li yuav muaj kev poob ntau dua hauv lub transformer. Rau tib lub zog tso zis, koj yuav xav tau ib qho loj me me transformer yog tias koj siv aluminium. Ntawm qhov tod tes, aluminium yog sib dua thiab pheej yig dua tooj liab. Zuag qhia tag nrho, tooj liab yeej . - tab sis txhua leej txhua tus yog tiaj tus sim tsim lub zog hloov hluav taws xob tawm ntawm txhua yam, uas yog vim li cas cov khoom siv tam sim no thiaj li teeb, pheej yig, thiab yuav tawg rau hauv cov nplaim taws.

 

Tooj liab muaj cov conductivity zoo dua aluminium, yog li nws cov cua sov poob qis dua. Ua kev sib txuas rau tooj liab winding yog yooj yim dua li ua nws rau aluminium winding. On lem aluminium yog sib dua li tooj liab thiab nws lub peev xwm kub yog li peb npaug ntawm ib qho ntawm tooj liab, yog li tso cai rau aluminiun whistand zoo dua tam sim no overloads. Los ntawm qhov pom ntawm corrosion aluminium yuav ua tau zoo dua tab sis cov xaim ntawm lub zog hloov hluav taws xob raws li zoo enameled tooj liab hlau yuav kav ntau xyoo.

 

Aluminium=Tsawg nqi
Copper=zoo dua rau txhua yam.

 

Nyob sab hauv tsev aluminium transformers hnyav hnyav dua li sab hauv tooj liab transformers, txawm tias tom qab ua rau lawv loj dua kom haum rau cov txhuas kom lawv cov kev ua tau zoo sib xws los yog tshaj qhov sib tw tooj liab transformer efficiency.

 

Qhov no yog qhov tseem ceeb tshaj plaws nyob rau hauv siab - nce chaw ua haujlwm cov tsev uas twb muaj qhov hnyav hnyav rau hauv pem teb (nrog rau cov kev pabcuam elevator) thiab tshwj xeeb tshaj yog rau ib square feet (lawv tsis tuaj yeem tuav cov khoom hnyav psi siab, zoo li cov dav hlau hauv pem teb nrog qee yam ntawm cov poj niam stiletto heels). Kuv tau ua haujlwm rau ib lub tuam txhab rau 13 xyoo uas tau tsim cov tshuab UPS uas muaj zog heev nrog cov hlau nplaum loj heev thiab peb feem ntau yeej kev txiav txim rau cov plag tsev sab saud ntawm siab -nce chaw ua haujlwm yees vim tias tus neeg sib tw tooj liab transformers tau tshaj qhov hnyav ib square feet pub rau lub tsev thiab elevators. Nco ntsoov tias cov no yog cov transformers loj hauv tsev ntawm 200kVA rau 600kVA loj. Cov no yog cov tshuab ua haujlwm uas nyob 3 feet x 6 feet x 6 feet los yog ntau dua. Qee lub tsev yuav tsum muaj zog txog li 8 MWs.
