Tam sim no -Tsev Muaj Peev Xwm, Kev Kho Hniav, Thiab Kev Siv Aluminium Busbars

Hais txog kev xaiv cov khoom siv, aluminium hluav taws xob busbars feem ntau yog tsim los siv siab - purity aluminium (xws li qib 1050 thiab 1060) lossis aluminium alloys (xws li qib 6063 thiab 6061). Ntawm cov kev xaiv no, 6061 aluminium busbar yog qhov nyiam heev vim nws cov yam ntxwv ua tau zoo heev. Cov khoom no muaj cov hluav taws xob conductivity xws li kwv yees li 55% mus rau 62% ntawm International Annealed Copper Standard (IACS), tab sis nws qhov ceev tsuas yog 30% ntawm tooj liab, uas ua rau muaj txiaj ntsig txo qhov hnyav. Tsis tas li ntawd, lub zog tensile ntawm 6-series aluminium alloys tuaj yeem ncav cuag li ntawm 150 thiab 300 MPa-ntau tshaj li ntawm cov ntshiab txhuas- ua rau lawv tshwj xeeb zoo rau cov ntawv thov uas muaj cov dej ntws siab thiab ib puag ncig muaj kev co; Qhov no tseem ceeb txhim kho ob qho tib si khoom durability thiab kev ua haujlwm ruaj khov.

Los ntawm qhov kev xav ntawm hluav taws xob kev ua tau zoo, kev ua haujlwm ntawm txhuas hluav taws xob busbars feem ntau yog li ntawm 35% mus rau 61% ntawm IACS, nrog rau cov nqi tshwj xeeb nyob ntawm qhov purity ntawm aluminium thiab hom alloy siv. Noj 1060 ntshiab txhuas ua piv txwv, nws cov conductivity yog kwv yees li 61%; Txawm li cas los xij, nws cov hluav taws xob tiv thaiv yog li 1.6 npaug ntawm tooj liab. Yog li ntawd, nyob rau hauv kev siv tswv yim, nws yog feem ntau yuav tsum tau nce tus ntoo khaub lig-sectional cheeb tsam ntawm lub busbar los them rau qhov qis conductivity. Piv txwv li, lub busbar ntsuas 100 × 10 mm tuaj yeem nqa tam sim no ntawm kwv yees li 1,200 txog 1,500 amperes hauv qhov kub thiab txias ntawm 40 degree. Feem ntau, qhov tso cai rau qhov kub nce thaum lub sijhawm ua haujlwm yog txwv rau qhov siab tshaj plaws ntawm 50 degree, txawm hais tias nyob rau hauv cov roj teeb pob, cov kev cai nruj dua feem ntau siv, txwv qhov kub nce mus rau tsis tshaj 30 degree.

Kev kho saum npoo yog ib kauj ruam tseem ceeb hauv kev txhim kho kev ua tau zoo ntawm tin -plated aluminium busbars. While aluminum naturally forms a dense oxide film when exposed to air, its corrosion resistance in humid or contaminated environments is limited; yog li ntawd, kev kho tshwj xeeb ntawm cov ntsiab lus txuas yog qhov tseem ceeb. Los ntawm cov txheej txheem tin-plating txheej txheem, tin-plated aluminium busbars tau txais ib txheej tin txheej rau ntawm lawv qhov chaw, zoo bolstering oxidation kuj thiab corrosion kuj ntawm cov hluav taws xob sib txuas. Tsis tas li ntawd, lwm yam kev kho deg-xws li npib tsib xee plating lossis nyiaj plating- tuaj yeem xaiv tau yooj yim raws li cov txheej txheem thov tshwj xeeb, yog li ua kom cov khoom lag luam tswj xyuas hluav taws xob txhim khu kev qha txawm nyob hauv ib puag ncig hnyav.

Nyob rau hauv lub tshav pob ntawm lub zog tshiab, aluminium busbars tsim rau kev sib txuas ntawm tes tau dhau los ua cov khoom tseem ceeb txuas cov roj teeb modules nrog lub zog faib hluav taws xob. Cov cuab yeej siv hluav taws xob tshiab feem ntau muaj kev hloov pauv tam sim no thaum lub sijhawm ua haujlwm, ua kom muaj kev nce siab tam sim no thaum pib lossis hloov pauv sai; ua tsaug rau lawv qhov zoo tshaj tam sim no - nqa lub peev xwm, aluminium busbars tau zoo heev hauv kev sib ntsib thiab tswj cov kev sib tw ua haujlwm no. Tsis tas li ntawd, lub teeb yuag ntawm aluminium busbars rau kev sib txuas ntawm tes txo cov kev xav tau ntawm lub zog rau kev txhawb nqa; rau cov tsheb hluav taws xob thiab lub zog khaws cia, qhov no txhais tau tias txo cov tsheb hnyav tag nrho thiab cov nqi qis dua.

Hauv cov khoom siv hluav taws xob, aluminium tiaj tus busbars rau switchgear sawv cev rau feem ntau daim ntawv thov. Lawv cov ntoo khaub lig-section ua kom yooj yim rau kev faib hluav taws xob zoo hauv qhov chaw kaw, thaum lawv thaj chaw loj loj kuj txhawb nqa cov cua sov kom zoo. Muab cov txhuas cov coefficient siab ntawm thermal expansion, kev sib txuas tsim yuav tsum muaj cov kev cai tsim nyog rau thermal expansion nyiaj kom ntseeg tau tias lub kaw lus tswj xyuas hluav taws xob ruaj khov thiab kev sib raug zoo ntawm cov neeg kho tshuab thaum muaj kev kub ntxhov.

Thaum xaiv aluminium tiaj tus busbars, nws raug nquahu kom ntsuas qhov ntsuas qhov tseem ceeb xws li tam sim no - nqa lub peev xwm, luv -circuit withstand peev, thiab cua sov dissipation tej yam kev mob. Ua kom ntseeg tau qhov kev sib tw kom zoo rau cov txhuas busbar hluav taws xob txuas hluav taws xob yog qhov tseem ceeb; cov neeg siv yuav tsum xaiv cov khoom tsim nyog raws li qhov xav tau tam sim no load thiab qhov tshwj xeeb installation ib puag ncig. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau cov ntaub ntawv pov thawj thiab cov ntaub ntawv xeem los txheeb xyuas cov kev ntsuas tseem ceeb-xws li hluav taws xob conductivity thiab qhov ntsuas kub ntawm qhov ntsuas kub- yog li ua kom muaj kev xaiv tus nqi ntau tshaj - cov kev daws teeb meem zoo. Yog koj muaj tej yam yuav tsum tau hais txog kev xaiv los yog customization ntawmaluminium tiaj tus busbarcov khoom, thov koj xav tiv tauj peb txhua lub sijhawm; peb cov kws tshaj lij pab pawg tau npaj los muab kev pabcuam tus kheej rau koj thiab kev daws teebmeem.
