A copper busbar is a conductor made of copper with a rectangular (or nearly rectangular) cross-section. Vim nws cov hluav taws xob zoo thiab thermal conductivity thiab tshuab lub zog, nws plays lub luag haujlwm tseem ceeb hauv ntau thaj teb, suav nrog hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho hluav taws xob, thiab kev tsim kho.
Tooj liab Busbars yog feem ntau ua los ntawm high - tooj liab tooj liab (nrog rau cov ntsiab lus tooj liab ntau dua los yog sib npaug rau 99.9%). Lawv cov ntoo khaub lig -} seem yog feem ntau cov duab sib dhos (xws li 100mm × 10mm), txawm hais tias muaj cov duab tshwj xeeb (xws li cov duab sib npaug. Lawv cov nplaim hluav taws xob feem ntau du thiab burr {{8} Pub dawb kom ntseeg tau tias kev sib cuag hluav taws xob zoo.
Tooj liab qhov hluav taws xob tau ua yog ob tsuas yog rau nyiaj, mus txog rau qib loj (tus qauv hauv ntiaj teb no (ua rau nws haum siab rau qhov siab tam sim no.
Nrog rau lub thermal conductivity ntawm kwv yees li 401w / (maper Busbars tuaj yeem sai sai dissipate kub thiab feem ntau siv hauv kev siv cua sov. Nyob rau hauv cov nqe lus ntawm cov tshuab muaj zog, tooj liab busbars muaj kev ua kom zoo dua thiab khoov tsis, ua rau lawv yooj yim rau cov txheej txheem thiab cov duab. Lawv kuj muab cov tshuaj zoo dua rau cov hlau xws li hlau thiab txhuas (lawv yog cov xeb qhuav, tab sis yuav tsum tau kho cov chaw ntub dej los yog acidic ib puag ncig). Hais txog huab cua tiv thaiv, lawv muab kev ua haujlwm ntau ntau (-40℃rau 120 degree) thiab siab ruaj khov.
Cia wb saib ntawm kev tsim khoom, cov kev qhia tshwj xeeb, thiab cov qauv tooj liab busbars.
1. Cov Txheej Txheem Ntau Lawm
- rolling: Qhov no yog cov roj av ntau tshaj plaws, cov paib tooj liab tau dov mus rau hauv tooj liab busebars ntawm cov tuab thiab dav siv lub pob zeb dov. Tus txheej txheem no muab cov kev ntsuas siab thiab ib qho chaw du.
{- Kos duab: Qhov no yog siv los ua cov chaw txhab nyiaj me me, tsim los ntawm kev tuag rau qhov ntev dua.
{- kev kho mob: nyob ntawm qhov yuav tsum tau ua, rau corrosion- kub ua hauj lwm (rau siab} Cov kua roj vanish (rau kev tiv thaiv kev tawm tsam).
2. Cov lus qhia tshwj xeeb thiab cov qauv
- loj npaum li cas: dav hlau feem ntau ntawm 10 txog 12 hli, thiab thicknesses los ntawm 3 txog 12 hli. Muaj cov kev cai tshwj xeeb (piv txwv li, ntxiv} pa busbars rau kev siv hluav taws xob} Conductivity, thiab cov kws kho tshuab (piv txwv li, kev ua haujlwm ntawm T2 Tooj Busbars yuav tsum muaj ntau dua lossis sib npaug ntawm 97% IRCS).
- Nqa tam sim no nqa muaj peev xwm: Tus loj dua tus ntoo khaub lig-}}}} nqa cov peev txheej tam sim no. Piv txwv li, 100mm X 10mm tooj liab Busbar muaj qhov muaj peev xwm nqa tau ntawm kwv yees li 2500a ntawm kev kub ntxhov ntawm kub thiab kub thiab txias thiab kev teeb tsa).
3. Kev sib piv nrog lwm tus neeg
- hyper busbar thiab Aluminium Busbar: Tooj neeg Busbars muaj qhov muaj txiaj ntsig, tab sis kuj tseem tuaj yeem them tus nqi siab dua (tooj liab tus nqi kwv yees li 3-5 zaug ntawm tus nqi ntawm txhuas). Lawv feem ntau siv nyob rau hauv cov ntawv thov uas xav tau kev ua haujlwm siab.
- tooj liab busbar vs. (xws li cov ntawv xa hluav taws xob zoo dua qub thiab cov kab ke siab dua thiab haum rau kev xa mus ntev. Cov hauv qab no yog lub ntsiab siv tooj liab busbars:
1. Fais fab system: Cheebtsam tseem ceeb rau kev ua thiab faib lub hwj chim
[Siab thiab qis dua hluav taws xob xa tawm chaw] ua haujlwm ua busbars (xws li cov khoom siv busbars (xws li lub hwv loj nyob rau hauv qhov qis {{voltage txee ntawm kev hloov).
[Busbar lub cev lub taub hau] hloov cov tsoos dej rau siab - kev xa rov qab los yog tav toj hauv tsev, muab cov cua sov yooj yim thiab yooj yim.
[Hloov pauv thiab muaj lub cev muaj zog sib txuas tau zoo {{voltage outging xov hlau, xav tau kev loj thiab tshuab zog.
[Cov tshuab hauv av] Raws li cov chaw nres tsheb loj, tooj liab ua rau muaj cov hlau, ua kom haum rau sab nraum zoov lossis dej tsaws chaw huab cua).
2. Electronics thiab kev sib txuas lus: precision Conductivity thiab cua sov dissipation
[PCBs thiab ua ke sib haum] siv raws li cov txheej txheem caperive ntawm high- lub tog raj ntawm cov tawv nqaij (Reveraging Tooj Liab Conductivity los sai sai dissipate kub).
[Cov khoom siv fais fab tuag] ua haujlwm busbars hauv cov inverters thiab rectifiers thiab rectifiers [Kev sib txuas lus hauv paus pib] Puv fais fab muab cov tawv nqaij uas tsis sib xws, ua rau muaj kev haum xeeb, ua rau haum rau siab- cov ntawv thov siab).
3. Kev tsim kho thiab engineering: grounding, xob tiv thaiv, thiab tshwj xeeb scararios
[Av thaiv thiab xob tiv thaiv kev tiv thaiv] av cov ntsiab lus tseem ceeb thiab xob laim qis thiab xob laim rau cov tsev siab. Qhov kev ua tau zoo thiab xeb tsis kam ntawm tooj liab busbars kom ntseeg tau tias kev ntseeg tau yooj yim (xws li subway glounding tshuab).
[Cov cuab yeej siv hluav taws xob] kws kho mob kub hnyiab, piv txwv li cov tooj liab lub siab thiab siab} kub tsis kam.
[Tshiab Zog] Innector Tsheb thauj mus rau hluav taws xob tsheb roj teeb (Nickel {{- cov lus tshaj tawm tam sim no nyob rau hauv chaw nres tsheb.
4. Kev lag luam thiab cov khoom siv tshwj xeeb: customized cov kev daws teeb meem
[Electrolysis thiab electroplating cov khoom siv] anode thiab cathode txuas nrog electrolytic cells yuav tsum muaj kev ua haujlwm siab thiab electrolyte corrosion.
[High {-} zaus Induction Induction Induction Intruction Cov Khoom Siv Hauv Hlau SMPERTANCE THIAB HIGH- zaus kev ua tau zoo.
[Rail Transit] busbars nyob rau hauv high - Ceev RAIT RAITERS xav tau kev ntseeg siab thiab kev co ua hauj. Thaum kawg, cia saib tooj liab busbar xaiv thiab kev txiav txim siab thov:
[Ampacity xam] Xaiv tus ntoo khaub lig-}}} seem ntawm qhov tam sim no, kub / ntsug) kom tsis txhob overheating.
[Deing Kho] Xaiv cov busned lossis galvanized busbars, tanned busding, thiab nyiaj} plated busbars rau high- cov khoom siv.
[Rwb thaiv tsev tiv thaiv] raug tooj liab busbars yuav tsum tau them nrog insulating sov shrink tubing lossis coated nrog insulating varnish kom tiv thaiv luv luv circuits.
[Cost Considerations] For large-scale applications, consider copper-aluminum composite busbars (to reduce costs while maintaining performance).
Tooj liab busbars, nrog lawv cov hluav taws xob hluav taws xob, nrog kev ua haujlwm kub thiab ua haujlwm yooj yim, tau dhau los ua cov khoom siv hluav taws xob hauv lub zog, cov khoom siv hluav taws xob, thiab kev tsim kho cov lag luam. Los ntawm busbars nyob rau hauv cov chaw faib khoom rau cov roj teeb sib txuas hauv cov ntawv siv hluav taws xob, los ntawm kev lag luam ib txwm muaj rau cov khoom siv hluav taws xob tshiab. Lawv yog cov hlab ntshav "ntawm cov tshuab hluav taws xob niaj hnub.
Lub tuam txhab muaj pawg ntawm cov coj tooj liab ua ntau lawm cov kab hauv Suav teb, suav nrog:
German tau yog precision tooj liab raj ntau lawm kab (ib xyoos tawm ntawm 30,000 tons)
Japanese technology Tooj liab ntawv tuav kab (thinnest txog li 6μm)
Tsis Siv Neeg Siab Tooj Liab Bar Nruam Extrusion Kab
Cov Ntawv Ntse Copper thiab Sawb Fining Mill Chav Tsev
Digitalized kev tswj hwm thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm tau pom los ntawm cov khoom siv ntawm cov khoom lag luam, thiab qhov tseeb ntawm cov khoom tuaj yeem ncav cuag ± 0.01 hli.
