Kev Taw Qhia Txog Busbar
Cov busbars yog cov khoom tseem ceeb hauv cov kab ke faib hluav taws xob, ua haujlwm ua txoj hauv kev xa hluav taws xob. Lawv siv rau hauv ntau yam kev siv, suav nrog cov switchboards, switchgear, thiab cov kab ke siv hluav taws xob rov ua dua tshiab. Kev nkag siab txog yam uas busbar ua los ntawm yog qhov tseem ceeb rau kev xaiv cov khoom siv zoo rau ib daim ntawv thov tshwj xeeb, vim tias cov khoom siv cuam tshuam ncaj qha rau kev ua tau zoo, kev ua haujlwm zoo, thiab kev ntseeg siab. Tsab xov xwm no yuav tshawb nrhiav cov khoom siv feem ntau siv hauv kev tsim busbar, lawv cov khoom, thiab cov txiaj ntsig ntawm txhua yam khoom siv.
Cov ntaub ntawv busbar feem ntau
1. Tooj liab
Tooj liab yog cov khoom siv dav tshaj plaws rau cov busbars vim nws cov hluav taws xob zoo heev. Nrog rau kev coj hluav taws xob ntawm kwv yees li 59.6 x 10 ^ 6 S / m, tooj liab busbars muaj peev xwm nqa cov dej ntws loj thaum txo qis kev poob hluav taws xob. Qhov impedance qis no ua rau tooj liab yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev faib hluav taws xob zoo, xws li cov chaw lag luam thiab cov chaw khaws ntaub ntawv.
Qhov zoo ntawm tooj liab busbar
Kev Ua Hluav Taws Xob Siab: Tooj Liab's zoo heev hluav taws xob conductivity kom zoo zog hloov nrog txo zog poob.
Tiv Thaiv Kev Xeb: Tooj liab yog qhov ntuj tiv taus kev xeb, uas ua rau nws lub neej ntev thiab kev ntseeg siab ntau yam hauv ntau qhov chaw.
Lub Zog Kho Tshuab: Cov tooj liab busbars muaj lub zog kho tshuab zoo heev thiab tsim nyog rau cov ntawv thov uas muaj kev co lossis kev ntxhov siab kho tshuab.
- Aluminium
Aluminium yog lwm yam khoom siv busbar uas siv ntau, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov hnyav thiab tus nqi yog qhov tseem ceeb xav txog. Txawm hais tias aluminium muaj qhov conductivity qis dua li tooj liab (kwv yees li 37.7 x 10 ^ 6 S / m), nws tseem yog tus conductor zoo thiab feem ntau siv rau hauv cov kab ke faib khoom loj.
Qhov zoo ntawm txhuas busbar
Lub teeb yuag: Aluminium sib dua li tooj liab, ua rau nws yooj yim dua rau kev tuav thiab teeb tsa, tshwj xeeb tshaj yog hauv kev teeb tsa loj.
Tus nqi tsim nyog: Aluminium feem ntau pheej yig dua li tooj liab, ua rau nws yog qhov kev xaiv pheej yig dua rau ntau daim ntawv thov.
Kev ua hluav taws xob zoo: Txawm hais tias txhuas tsis muaj hluav taws xob ntau dua li tooj liab, nws tseem tuaj yeem nqa tau ntau yam tam sim no zoo, tshwj xeeb tshaj yog thaum tsim nrog thaj chaw loj.
3. Tooj liab hlau busbar
Cov hlau tooj liab xws li tooj dag lossis tooj dag qee zaum siv rau cov busbars los sib xyaw cov txiaj ntsig ntawm tooj liab nrog cov khoom siv kho tshuab zoo dua. Cov hlau no tuaj yeem muab lub zog ntxiv thiab kev tiv thaiv kev hnav, ua rau lawv haum rau cov ntawv thov tshwj xeeb.
Qhov zoo ntawm tooj liab alloy busbar
Muaj Zog Ntxiv: Cov hlau tooj liab tuaj yeem muab lub zog kho tshuab siab dua li tooj liab ntshiab, ua rau lawv haum rau cov chaw muaj kev ntxhov siab siab.
Kev tiv thaiv corrosion: Ntau cov hlau tooj liab ua rau muaj kev tiv thaiv corrosion zoo heev, uas tuaj yeem ua rau lub neej ntawm lub busbar ntev dua thaum muaj kev kub ntxhov. tej yam kev mob
Cov yam tseem ceeb uas cuam tshuam rau kev xaiv cov khoom siv
Thaum xaiv cov khoom siv busbar, ntau yam yuav tsum tau xav txog:
1. Tam sim no muaj peev xwm nqa tau
Qhov conductivity ntawm ib yam khoom cuam tshuam ncaj qha rau nws lub peev xwm los nqa hluav taws xob tam sim no. Rau cov ntawv thov uas xav tau tam sim no ntau dua, cov ntaub ntawv uas muaj conductivity ntau dua, xws li tooj liab, yog qhov zoo dua.
2. Tej yam ib puag ncig
Qhov chaw ua haujlwm ua lub luag haujlwm tseem ceeb hauv kev xaiv cov khoom siv. Piv txwv li, yog tias lub busbar yuav raug rau cov dej noo lossis cov tshuaj corrosive, cov ntaub ntawv uas muaj kev tiv thaiv corrosion siab (xws li tooj liab lossis qee cov alloys) yog qhov zoo tagnrho.
3. Kev txwv qhov hnyav thiab qhov chaw
Hauv cov ntawv thov uas qhov hnyav yog qhov txhawj xeeb, xws li kev thauj mus los lossis aerospace, cov tsheb npav aluminium yuav raug nyiam rau lawv qhov hnyav sib dua.
4. Kev Xav Txog Tus Nqi
Kev txwv nyiaj txiag tuaj yeem cuam tshuam loj heev rau kev xaiv cov khoom siv. Txawm hais tias tooj liab muaj kev ua tau zoo dua, txhuas yuav yog qhov kev daws teeb meem pheej yig dua rau qee qhov kev siv.
xaus lus
Hauv kev xaus, cov busbars feem ntau yog ua los ntawm cov ntaub ntawv xws li tooj liab, txhuas, thiab tooj liab alloys, txhua tus muaj cov txiaj ntsig thiab cov khoom tshwj xeeb. Tooj liab yog lub npe hu rau nws cov hluav taws xob conductivity siab thiab lub zog kho tshuab, thaum txhuas yog qhov sib dua thiab pheej yig dua. Kev nkag siab txog cov ntaub ntawv siv hauv kev tsim busbar yog qhov tseem ceeb rau kev xaiv cov kev daws teeb meem zoo rau daim ntawv thov tshwj xeeb, xyuas kom meej tias muaj kev ua tau zoo tshaj plaws, kev ua haujlwm zoo, thiab kev ntseeg siab ntawm lub zog faib hluav taws xob. Los ntawm kev xav txog cov yam ntxwv xws li lub peev xwm nqa tam sim no, cov xwm txheej ib puag ncig, kev txwv qhov hnyav, thiab tus nqi, cov engineers thiab cov neeg tsim qauv tuaj yeem txiav txim siab paub zoo uas txhim kho kev ua haujlwm ntawm cov kab ke hluav taws xob.
