Copper Vs Aluminium Transformer Windings: Yam twg zoo dua?
Thaum nws los txog rau transformer windings, ob lub ntsiab khoom koj yuav pom yogtooj liabthiabaluminium. Cov no yog cov conductors uas nqa tam sim no thiab ua rau tag nrho cov electromagnetic induction khoom ua haujlwm.
Copper Windings
tooj liab tseem yog qhov mus- xaiv rau siab- kawg, compact, lossis hnyav- lub luag haujlwm transformers.
Vim li cas tib neeg nyiam nws:
Nws ua hluav taws xob zoo dua li txhuas (kwv yees li 1.6 npaug zoo dua), yog li koj tau txais kev poob qis thiab ua haujlwm ntau dua.
Nws muaj zog dua mechanically, uas txhais tau hais tias nws ua haujlwm luv luv -circuit rog, kev co, thiab kev tuav ntxhib zoo dua.
Vim hais tias nws yog cov conductive ntau dua, koj tuaj yeem siv cov conductors me, uas ua rau tag nrho cov hloov pauv ntau dua.
Nws kuj dissipates cua sov zoo dua.
Qhov downside? Tooj liab yog pom tias kim dua thiab hnyav dua.
Aluminium Windings
Niaj hnub no, txhuas tau dhau los ua ntau yam - tshwj xeeb tshaj yog nyob rau hauv kev faib khoom transformers, qhuav -hom units, thiab ntau tus nqi-sensitive tej yaam num. Muaj ntau manufacturers tau hloov mus rau nws raws li lub neej ntawd.
Qhov zoo:
Nws yog pheej yig dua, uas ua rau muaj qhov sib txawv loj ntawm tus nqi kawg.
Ntau qhov hnyav dua, yog li shipping thiab installation yooj yim dua.
Nrog rau lub tshuab hluav taws xob tsim kom zoo (siv tus ntoo khaub lig loj dua -section los them rau qis conductivity), txhuas ua tau zoo heev thiab tuaj yeem ua tau raws li tooj liab lub neej yooj yim.
Tau kawg, nws tsis zoo tag nrho. Koj xav tau tus neeg xyuas pib loj dua rau tib lub sijhawm tam sim no, thiab lub zog txhua yam yog qis dua, yog li kev sib txuas yuav tsum tau saib xyuas ntxiv kom tsis txhob xoob lossis oxidation teeb meem nyob rau lub sijhawm.

Kev sib piv ceev
Qhov tseeb yog, thaum tsim txoj cai, ob qho tib si cov ntaub ntawv tuaj yeem xa cov kev ua haujlwm zoo sib xws thiab kev ntseeg siab. Feem ntau nws los rau ntawm daim ntawv thov tshwj xeeb thiab pob nyiaj siv.
Lwm Cov Lus Qhia Tseem Ceeb
Windings tuaj yeem ua los ntawm cov hlau puag ncig, lub voj voos, lossis cov ntawv ci (cov ntawv ci ntau heev rau qis-voltage sab). Lawv raug insulated nrog ntawv, Nomex, enamel, los yog cam khwb cia resin nyob ntawm seb nws puas yog roj - puv los yog qhuav - hom transformer.
Cov kab hauv qab:Yog tias qhov chaw, kev ua haujlwm, lossis kev ntseeg siab heev yog qhov tseem ceeb, mus nrog tooj liab. Yog tias koj tab tom sim khaws cov nqi thiab qhov hnyav yam tsis muaj kev ua haujlwm ntau dhau lawm, niaj hnub aluminium windings yog ib qho khoom, kev xaiv dav. Nco ntsoov xyuas cov chaw tsim khoom tshwj xeeb rau koj qhov tshwj xeeb voltage thiab kVA ntsuas.
