Tam sim no, winding ntawm transformer yog tsuas yog ua los ntawm tooj liab hlau thiab tooj liab ntawv ci, tab sis kuj ua los ntawm txhuas hlau thiab txhuas ntawv ci. Txawm li cas los xij, muaj kev tsis sib haum xeeb txog qhov tsis xws ntawm tooj liab winding transformer thiab aluminium winding transformer. Tam sim no, aluminium winding transformer yog dav siv nyob rau hauv tis transformer, tshwj xeeb tshaj yog nyob rau hauv cov teb chaws Europe, North America, Latin America thiab lwm cheeb tsam.
Kev sib piv ntawm cov tooj liab thiab txhuas: Xav txog tus nqi- kev ua tau zoo thiab muaj, kev lag luam feem ntau siv tooj liab thiab txhuas rau transformer conductors, nrog rau lawv qhov sib txawv tseem ceeb:
1. resistivity
2. ceev
3. cov nyhuv ntawm daim tawv nqaij
4. kev sib txuas
5. machinability
6. mechanical cwj pwm
1. Resistivity thiab ntom
Aluminium tus hluav taws xob conductivity yog kwv yees li 62% ntawm tooj liab. Txhawm rau ua tiav qhov kev tiv thaiv tib yam, aluminium conductors yuav tsum muaj tus ntoo khaub lig-sectional cheeb tsam 62% loj dua tooj liab. Qhov no yuav tsum muaj tus ntoo khaub lig loj dua- ntu kom tswj tau qhov sib npaug, uas ua rau kom muaj lwm yam khoom siv hauv lub zog hloov hluav taws xob, xws li hlau cores thiab enclosures. Txawm li cas los xij, aluminium qhov ntom ntom yog qis dua tooj liab (2.7 kg / dm³ vs . 8.9 kg / dm³). Rau tib qhov kev tiv thaiv thiab winding ntev (nrog zoo tib yam poob), aluminium qhov loj yog txo los ntawm ib nrab.
2. tensile zog
Aluminium muaj zog tensile qis dua tooj liab. Txawm li cas los xij, thaum muab piv rau cov khoom siv tooj liab ua tau zoo ib yam, qhov sib ntxiv ntawm -sectional thaj tsam ntawm aluminium conductors pab offset nws qis yield zog.
3. Thermal Performance and Short-Circuit Thermal Stability
Kev sib piv ntawm luv luv -circuit thermal stability ntawm tooj liab thiab txhuas winding transformers ntawm tib tus qauv
Rau tib lub transformer qauv, qhov sib piv ntawm luv luv -circuit endurance ntawm tooj liab thiab txhuas transformers yog qhia nyob rau hauv daim duab hauv qab no (raws li GB1094.5-2008, tooj liab withstands 350℃thiab txhuas 200℃).
Copper luv-circuit tam sim no withstand sij hawm/S Aluminium luv-circuit tam sim no withstand sij hawm/S
Kev sib piv hauv daim duab saum toj no qhia tau hais tias rau transformers ntawm tib tus qauv, qhov kub thiab txias ntawm tooj liab thiab txhuas transformers yog qhov tseem ceeb tib yam nyob rau hauv zoo tib yam luv luv -circuit tam sim no thiab lub sij hawm, tab sis tooj liab transformers muaj peev xwm tiv tau lub luv luv - Circuit Court tam sim no rau lub sij hawm ntev tshaj li txhuas transformers.
