Corrosion kuj
Lwm qhov txiaj ntsig tseem ceeb ntawm tooj liab yog nws lub ntuj tiv thaiv corrosion. Cov yam ntxwv no ua rau muaj kev ua haujlwm ntev thiab kev pab cuam lub neej ntawm tooj liab busbar, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov dej noo los yog corrosive. Copper's corrosion kuj pab tswj kev ncaj ncees ntawm kev sib txuas hluav taws xob, kom ntseeg tau tias kev ua haujlwm ntev ntev.
Mechanical Strength
Copper kuj muaj lub zog txhua yam zoo, tso cai rau nws tiv taus siab thiab lim yam tsis muaj deforming. Qhov no feature yog tshwj xeeb tshaj yog tseem ceeb nyob rau hauv daim ntawv thov uas lub busbar tej zaum yuav raug kev co los yog thermal expansion. Lub zog txhua yam ntawm tooj liab busbars pab txhawb rau lawv txoj kev ntseeg siab thiab kev nyab xeeb hauv ntau lub tshuab hluav taws xob.
Lwm cov ntaub ntawv rau busbars
aluminium
Thaum tooj liab yog ib qho kev xaiv nrov, aluminium yog nce siv los ua lwm yam khoom siv rau busbars. Aluminium muaj qhov hluav taws xob conductivity ntawm kwv yees li 37.7 x 10^6 S / m, uas yog qis dua tooj liab tab sis tseem txaus rau ntau daim ntawv thov.
Qhov zoo ntawm aluminium busbar
Lub teeb: Aluminium yog qhov sib zog ntau dua tooj liab, ua kom yooj yim rau kev tuav thiab nruab. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev siv qhov hnyav-sensitive, xws li tsheb fais fab thiab aerospace.
Nqi-zoo: Feem ntau hais lus, aluminium busbars pheej yig dua tooj liab, ua rau lawv muaj kev xaiv pheej yig dua rau ntau txoj haujlwm.
Txaus conductivity: Txawm hais tias txhuas muaj cov khoom siv hluav taws xob tsawg, nws tseem tuaj yeem nqa cov khoom siv tam sim no tau txais txiaj ntsig zoo, tshwj xeeb tshaj yog thaum tsim los nrog thaj tsam loj.
Tooj alloy busbar
Copper alloys xws li tooj dag lossis tooj liab yog qee zaum siv rau busbars los ua ke qhov zoo ntawm tooj liab nrog nws 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: Copper 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 kuj: Ntau cov tooj liab alloys muaj kev tiv thaiv zoo heev, uas tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm lub busbar nyob rau hauv hnyav hnyav.
Lwm yam khoom siv
Ntxiv nrog rau tooj liab thiab txhuas, busbars kuj tseem ua los ntawm lwm cov ntaub ntawv xws li stainless hlau thiab cov ntaub ntawv sib xyaw hauv cov ntawv tshwj xeeb.
Stainless hlau busbar
Stainless hlau muaj zoo corrosion kuj thiab mechanical zog, haum rau ib puag ncig uas yuav tsum tau muaj ob yam khoom. Txawm li cas los xij, nws cov conductivity qis dua cov tooj liab thiab txhuas, uas yuav txwv tsis pub nws siv hauv cov ntawv thov tam sim no.
Composite busbar
Cov ntaub ntawv sib xyaw, uas yuav suav nrog kev sib xyaw ntawm cov hlau thiab cov ntaub ntawv insulating, kuj tseem raug tshawb nrhiav rau cov ntawv thov busbar. Cov ntaub ntawv no tuaj yeem muab cov khoom tshwj xeeb xws li cov qauv teeb pom kev zoo thiab txhim kho kev tswj xyuas thermal.
Yam cuam tshuam rau kev xaiv cov khoom siv
Thaum txiav txim siab seb tooj liab puas tsim nyog rau busbars, 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 hluav taws xob ntau dua xws li tooj liab yog nyiam. Txawm li cas los xij, aluminium kuj tuaj yeem ua lwm txoj hauv kev yog tias tsim tau zoo.
2. Ib puag ncig tej yam kev mob
Qhov chaw ua haujlwm yog qhov tseem ceeb rau kev xaiv cov khoom siv. Yog hais tias cov busbars 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 siv. Thaum tooj liab muaj cov khoom zoo heev, aluminium tej zaum yuav yog ib qho kev siv nyiaj ntau dua rau qee qhov kev siv.
nyob rau hauv xaus
Hauv cov ntsiab lus, thaum tooj liab yog ib qho kev xaiv zoo thiab ib txwm siv rau busbars vim nws cov conductivity zoo, corrosion kuj, thiab txhua yam muaj zog, nws tsis yog tib txoj kev xaiv. Aluminium, tooj liab alloys, stainless hlau thiab cov ntaub ntawv sib xyaw kuj tseem tuaj yeem siv tau, nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov. Kev nkag siab txog qhov zoo thiab kev txwv ntawm txhua yam khoom siv yog qhov tseem ceeb rau kev txiav txim siab kom paub meej los txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov tshuab hluav taws xob. Thaum kawg, kev xaiv cov khoom siv busbar yuav tsum ua raws li kev soj ntsuam kom zoo ntawm daim ntawv thov, ib puag ncig, thiab kev xav txog nyiaj txiag.
