Busbar Taw Qhia
Busbars yog cov khoom tseem ceeb hauv lub tshuab hluav taws xob, ua txoj hauv kev rau kev xa hluav taws xob tam sim no. Lawv yog siv nyob rau hauv ntau yam kev siv, xws li switchboards, switchgear, thiab lub zog tauj dua tshiab. Kev nkag siab txog dab tsi lub busbar yog tsim los ntawm qhov tseem ceeb rau kev xaiv cov khoom tsim nyog rau ib daim ntawv thov tshwj xeeb, vim tias cov khoom cuam tshuam ncaj qha rau kev ua tau zoo, kev ua tau zoo, thiab kev ntseeg tau. Kab lus no yuav tshawb txog cov khoom siv uas siv hauv kev tsim kho busbar, lawv cov khoom, thiab cov txiaj ntsig ntawm txhua yam khoom siv.
Cov khoom siv busbar
1. Tooj
Tooj liab yog cov khoom siv dav tshaj plaws rau busbars vim nws cov hluav taws xob zoo heev. Nrog ib tug conductivity ntawm kwv yees li 59.6 x 10 ^ 6 S / m, tooj liab busbars muaj peev xwm nqa tau loj tam sim no thaum txo lub zog poob. 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 tsim khoom thiab cov chaw khaws ntaub ntawv.
Qhov zoo ntawm tooj liab busbar
High Electrical Conductivity: Tooj's zoo heev hluav taws xob conductivity ua kom muaj zog hloov pauv nrog txo lub zog poob.
Corrosion Resistant: tooj liab yog ib txwm resistant rau corrosion, uas ua rau kom nws lifespan thiab kev ntseeg siab nyob rau hauv ntau yam ntawm ib puag ncig.
Mechanical Strength: Copper busbars muaj lub zog zoo heev thiab tsim nyog rau cov ntawv thov uas muaj kev vibration lossis mechanical stress.
- Aluminium
Aluminium yog lwm cov khoom siv busbar, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov qhov hnyav thiab tus nqi yog qhov tseem ceeb rau kev txiav txim siab. Txawm hais tias txhuas muaj qhov qis qis dua tooj liab (kwv yees li 37.7 x 10 ^ 6 S / m), nws tseem yog tus neeg xyuas pib zoo thiab feem ntau siv hauv cov tshuab xa khoom loj.
Qhov zoo ntawm aluminium busbar
Lub teeb yuag: Aluminium yog qhov sib zog dua li tooj liab, ua kom yooj yim rau kev tswj thiab txhim kho, tshwj xeeb tshaj yog nyob rau hauv kev teeb tsa loj.
Tus nqi zoo: Aluminium feem ntau tsis tshua kim dua tooj liab, ua rau nws muaj kev xaiv pheej yig dua rau ntau daim ntawv thov.
Kev siv hluav taws xob zoo: Thaum txhuas tsis tshua muaj hluav taws xob ntau dua tooj liab, nws tseem tuaj yeem nqa cov khoom siv tam sim no tau zoo, tshwj xeeb tshaj yog thaum tsim nrog thaj tsam loj.
3. Copper alloy busbar
Copper alloys xws li tooj dag lossis bronze yog qee zaum siv rau busbars los ua ke qhov zoo ntawm tooj liab nrog cov khoom siv kho kom zoo. Cov alloys no tuaj yeem ua kom muaj zog thiab hnav tsis kam, ua rau lawv haum rau cov kev siv tshwj xeeb.
Qhov zoo ntawm tooj liab alloy busbar
Ua kom muaj zog: tooj liab alloys tuaj yeem muab kev siv zog ntau dua li cov tooj liab ntshiab, ua rau lawv haum rau qhov chaw muaj kev ntxhov siab.
Corrosion tsis kam: Ntau cov tooj liab alloys pom zoo heev corrosion kuj, uas tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm busbar hauv qab hnyav. tej yam kev mob
Yam cuam tshuam rau kev xaiv cov khoom siv
Thaum xaiv cov khoom siv busbar, ntau yam yuav tsum tau xav txog:
1. Lub peev xwm nqa tam sim no
Lub conductivity ntawm ib yam khoom ncaj qha cuam tshuam nws lub peev xwm nqa hluav taws xob tam sim no. Rau cov ntawv thov uas xav tau ntau dua tam sim no, cov khoom siv nrog cov khoom siv hluav taws xob ntau dua, xws li tooj liab, nyiam dua.
2. Ib puag ncig tej yam kev mob
Kev ua haujlwm ib puag ncig ua lub luag haujlwm tseem ceeb hauv kev xaiv cov khoom siv. Piv txwv li, yog hais tias lub busbar yuav raug ya raws los yog corrosive tshuaj, cov ntaub ntawv uas muaj corrosion kuj (xws li tooj liab los yog tej alloys) yog zoo tagnrho.
3. Qhov hnyav thiab qhov chaw txwv
Nyob rau hauv daim ntawv thov qhov hnyav yog ib qho kev txhawj xeeb, xws li kev thauj mus los lossis aerospace, aluminium busbars yuav nyiam rau lawv qhov hnyav.
4. Kev txiav txim siab nqi
Kev txwv nyiaj txiag tuaj yeem cuam tshuam rau kev xaiv cov khoom. Thaum tooj liab muaj kev ua tau zoo tshaj plaws, aluminium tej zaum yuav yog qhov kev daws teeb meem zoo dua rau qee yam kev siv.
nyob rau hauv xaus
Hauv cov ntsiab lus, busbars feem ntau yog tsim los ntawm cov ntaub ntawv xws li tooj liab, txhuas, thiab tooj liab alloys, txhua qhov muaj cov txiaj ntsig tshwj xeeb thiab cov khoom. Copper paub txog nws cov hluav taws xob hluav taws xob siab thiab lub zog ua haujlwm, thaum txhuas yog qhov sib tw thiab raug nqi. Kev nkag siab txog cov ntaub ntawv siv hauv kev tsim kho busbar yog qhov tseem ceeb rau kev xaiv txoj kev daws teeb meem rau ib daim ntawv thov tshwj xeeb, kom ntseeg tau tias kev ua tau zoo, kev ua tau zoo, thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. Los ntawm kev xav txog yam xws li lub peev xwm nqa tam sim no, ib puag ncig, kev txwv qhov hnyav, thiab tus nqi, engineers thiab designers tuaj yeem txiav txim siab paub txog kev txhim kho kev ua haujlwm ntawm cov tshuab hluav taws xob.
