Basic Knowledge ntawm Copper Busbars: Material Properties, Applications, and Quality Influencing Factors

Copper busbars yog cov khoom siv hluav taws xob ua los ntawm siab -purity tooj liab. Lawv muaj npe rau lawv cov purplish -liab xim hlau luster tom qab oxidation nto. Raws li cov khoom siv hluav taws xob raug hluav taws xob, cov busbars tooj liab muaj cov khoom siv hluav taws xob zoo heev, thermal conductivity, thiab cov khoom siv hluav taws xob ruaj khov, ua rau lawv siv dav hauv lub zog tshiab, kev xa hluav taws xob thiab kev xa tawm, hluav taws xob automation, thiab kev tswj hwm kev lag luam. Cov khoom lag luam muaj xws li Cov Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag Khoom Muag:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Copper busbars typically have low oxygen content, a dense internal structure, and are free from significant porosity, inclusions, or looseness, thus maintaining stable operation in high-current transmission environments. Vim lawv qhov tsis muaj zog, lawv txo qis hluav taws xob zoo, ua rau lawv siv dav hauv cov khoom siv hluav taws xob, cov tsheb npav fais fab, thiab cov khoom siv hluav taws xob sib txuas xws li siab -voltage thiab low-voltage busbars.

 

Los ntawm daim ntawv thov kev xav, tooj liab busbars tau dav siv nyob rau hauv siab thiab qis voltage switchgear, tis txee, transformers, hluav taws xob tswj systems, lub zog cia li, tshiab zog tsheb, electrolysis engineering, thiab industrial automation khoom. Hauv cov tshuab hluav taws xob niaj hnub no, AC busbars feem ntau yog siv hauv AC kis tau tus mob, thaum qee lub tshuab hluav taws xob tshiab siv qhov zoo thiab qhov tsis zoo rau DC kev sib txuas tsim kom tau raws li kev ruaj ntseg thiab siab tam sim no - nqa lub peev xwm.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Tam sim no, tooj liab busbar cov ntaub ntawv nyob rau hauv kev ua lag luam feem ntau muab faib ua ntau pawg: tooj liab zoo tib yam, oxygen- tooj liab dawb, deoxidized tooj liab, thiab tooj liab tshwj xeeb. Cov qib tooj liab zoo xws li T1, T2, T3, T4, thiab lwm yam; oxygen-dawb tooj liab suav nrog TU1, TU2, thiab nqus pa oxygen{10}}dawb tooj liab; cov qib deoxidized tooj liab muaj xws li TUP thiab TUMn; qee qhov kev ua haujlwm tshwj xeeb kuj tseem siv nyiaj tooj liab, tellurium tooj liab, lossis arsenic tooj liab cov ntaub ntawv nrog ntxiv cov kab sib txuas ntxiv. Cov ntaub ntawv sib txawv muaj qee qhov sib txawv hauv kev coj ua, weldability, oxidation tsis kam, thiab machinability. Yog li ntawd, nyob rau hauv kev tsim ntawm kev cai busbars, xaiv cov khoom yuav tsum tau raws li nyob rau hauv tiag tiag kev ua hauj lwm tej yam kev mob.

 

Ib qho ntawm qhov zoo tshaj plaws ntawm cov tooj liab busbars yog nyob rau hauv lawv cov hluav taws xob conductivity. Copper tus conductivity yog qhov thib ob tsuas yog nyiaj, ua rau nws ntev - sawv ntsug cov khoom siv hluav taws xob. Rau cov khoom siv uas yuav tsum tau muaj tam sim no siab - nqa lub peev xwm thiab kev ruaj ntseg siab, cov khoom siv tooj liab ua tau zoo txo ​​qhov tsim hluav taws xob thiab txhim kho kev ua haujlwm. Cov khoom siv hluav taws xob zoo heev tau dhau los ua cov khoom tseem ceeb hauv cov khoom loj hauv - teev lub zog cia, cov tshuab hluav taws xob muaj zog, thiab BusBar ABB cov tshuab faib khoom.

 

Dhau li ntawm conductivity, khoom tooj liab busbars kuj muaj kev ua haujlwm zoo thiab vuam zog. Lawv cov ductility zoo tso cai rau ntau yam kev xav tau, suav nrog stamping, dabtsi yog khoov, drilling, vuam, thiab kho qhov chaw. Yog li ntawd, lawv tau siv dav hauv PCB busbars, hluav taws xob tswj kev sib txuas, thiab cov txheej txheem tsis tu ncua tsis tu ncua. Rau qee cov khoom siv tshwj xeeb, cov kev daws teeb meem busbar customized yog siv los ua kom tau raws li qhov chaw sab hauv thiab cov kev xav tau ntawm cov cua kub dissipation.

 

Nyob rau hauv cov nqe lus ntawm lub cev khoom, cov khoom tooj liab busbars muaj ib tug melting point ntawm kwv yees li 1083℃thiab ib tug ceev ntawm kwv yees li 8.9 g / cm³, exhibiting zoo tshav kub kuj thiab stability. Txawm hais tias nws lub zog thiab hardness yog qis dua li ntawm qee cov ntaub ntawv hlau alloy, nws qhov kev ua tau zoo ua rau nws yog ib qho ntawm cov ntaub ntawv tseem ceeb siv los ntawm tooj liab busbar manufacturers.

 

Corrosion kuj yog ib qho tseem ceeb ntawm cov tooj liab busbars. Tooj liab nthuav tawm kev ruaj ntseg zoo hauv atmospheric, marine, thiab qee qhov tsis muaj zog acidic thiab alkaline ib puag ncig. Yog li ntawd, tooj liab hauv av busbars feem ntau siv nyob rau hauv lub hwj chim grounding systems, substations, thiab industrial fais fab kev faib ib puag ncig. Rau ntev - lub sij hawm ua hauj lwm fais fab kis tau tus mob thiab cov khoom siv tis, corrosion kuj tuaj yeem ua rau cov cuab yeej siv tau zoo thiab txo cov nqi tu.

 

Cov yam ntxwv cuam tshuam rau qhov zoo ntawm cov tooj liab busbars feem ntau suav nrog cov khoom siv raw purity, kev siv thev naus laus zis, chaw cia khoom, thiab cov txheej txheem kho saum npoo. High- zoo tooj liab busbars feem ntau yuav tsum tau ib tug du nto, tsis muaj kab nrib pleb, oxide me ntsis, thiab pom tseeb khawb, thaum muaj ib tug zoo conductivity thiab ib tug ruaj khov nyob rau hauv cov qauv.

 

Qhov kub thiab txias yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm cov tooj liab busbars. Nyob rau hauv chav tsev kub, tooj liab oxidizes maj mam; Raws li qhov kub thiab txias, oxidation tus nqi nce ntau. Thaum qhov kub siab tshaj 185 degree, nto oxidation nrawm heev, txawm tsim ib txheej oxide dub. Yog li ntawd, nyob rau hauv siab -voltage busbar daim ntaub ntawv, nto tin plating, npib tsib xee plating, los yog insulating txheej feem ntau yuav tsum tau los txo cov teebmeem ntawm oxidation.

 

Cov av noo kuj cuam tshuam rau qhov zoo ntawm cov tooj liab busbars. Nyob rau hauv ib puag ncig ntub, noo noo nyob rau hauv cov huab cua accelerates oxidation cov tshuaj tiv thaiv ntawm tooj liab nto, ua rau discoloration los yog corrosion. Yog li ntawd, ntau lub tshuab busbar manufacturers ntxiv los tiv thaiv - oxidation ntim lossis rwb thaiv tsev kho tom qab tsim khoom los txhim kho lub sijhawm ntev - khaws cia thiab kev thauj mus los ruaj khov ntawm cov khoom.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Thaum lub sij hawm ua, lubricant residue tuaj yeem cuam tshuam qhov zoo ntawm cov tooj liab busbars. Yog hais tias lub nruab nrab lubricating siv nyob rau hauv stretching, stamping, thiab dabtsi yog khoov cov txheej txheem tsis huv huv, nws yuav ua rau corrosion los yog oxidation marks ntawm qhov chaw. Yog li ntawd, tooj liab busbar cov neeg muag khoom feem ntau ntxiv dag zog rau kev tswj xyuas cov txheej txheem ntxuav thiab ziab kom huv si ntawm cov khoom nto.

 

Nrog rau txoj kev loj hlob ntawm lub zog tshiab kev lag luam, hluav taws xob tsheb, lub zog cia tshuab, thiab cov phiajcim ntse, qhov kev thov rau kev lag luam tsheb npav xws li BusBar rau Siemens, BusBar rau Eaton, BusBar rau Weidmuller, thiab BusBar rau Mersen Ferraz txuas ntxiv mus. Nyob rau tib lub sijhawm, siab -precision conductive connectors xws liCopper BusBar rau Siemensyog maj mam txhim kho mus rau siab dua tam sim no - nqa peev xwm, kev sib koom ua ke ntau dua, thiab kev hloov pauv. Thaum xaiv cov tooj liab busbars, cov kev txiav txim siab tseem ceeb yuav tsum tau muab rau cov khoom siv purity, conductivity, qhov tseeb qhov tseeb, qhov chaw saum npoo, thiab kev ua haujlwm ruaj khov. High- cov khoom lag luam zoo feem ntau muaj qhov ua tiav zoo tshaj plaws, tsis muaj kab nrib pleb, tev, npuas, thiab oxidation tseem ceeb, thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm ntev - lub sijhawm siab - haujlwm tam sim no. Rau lub zog tshiab, cov cuab yeej siv hluav taws xob, thiab kev lag luam automation sectors, ruaj khov thiab txhim khu kev qha tooj liab busbar manufacturers thiab paub tab ua technologies yog ib qho tseem ceeb rau kev ua kom lub sij hawm ntev - lub sij hawm ruaj khov kev lag luam ntawm busbar systems.
