Lub hauv paus ntsiab lus tseem ceeb thiab cov txheej txheem tsim nyog ntawm kev ntxiv solder nyob rau hauv tooj liab khoom busbar vuam

Hauv kev lag luam ntawm cov khoom siv hluav taws xob ua thiab cov hlau vuam, tooj liab cov khoom siv tsheb npav welding yog cov txheej txheem tseem ceeb rau kev tsim cov khoom siv hluav taws xob ua tiav thiab cov khoom siv hluav taws xob, thiab nws kuj yog cov txheej txheem tseem ceeb los xyuas kom muaj kev sib txuas hauv Circuit Court ruaj khov. Ntau tus kws kho mob yuav xav paub tias yog vim li cas cov hlau txuas ntxiv yuav tsum tau ntxiv los ntawm kev sib txuas ncaj qha rau High voltage busbars ua los ntawm cov khoom siv tooj liab. Hard tooj liab bar vuam tej zaum yuav zoo li yooj yim rau kev khiav lag luam, tab sis nws yeej muaj ib tug dual logic ntawm cov ntaub ntawv science thiab vuam technology. Ntxiv solder tsis yog ib qho tseem ceeb kauj ruam, tab sis ib tug tseem ceeb txuas kom ntseeg tau tias vuam zoo.

The core function of solder is to fill the micro gaps on the surface of the Ground bus bar and comprehensively optimize the conductivity of the joint. Cov tawv tooj liab zoo nkaus li du thiab tiaj tus thaum xub thawj siab ib muag, tab sis nyob rau hauv lub tshuab ntsuas, nws yog them nrog me me pob thiab qhov khoob. Qhov kev sib cuag zoo ntawm kev sib txuas ncaj qha yog qhov tsawg heev, uas ncaj qha txo qis cov conductivity efficiency. Lub melted solder tuaj yeem ua tiav qhov sib txawv ntawm qhov sib cuag ntawm cov tawv tooj liab tuav, tsim kom muaj txoj kev ua tiav, txo kev sib koom ua ke, thiab txhim kho kev sib kis tam sim no.

Solder tuaj yeem txhim kho cov khoom siv hluav taws xob ntawm hluav taws xob tsheb npav welded pob qij txha thiab txhim kho kev sib txuas tag nrho. Lub weld seam ncaj qha welded nrog ntshiab tawv tooj liab tuav muaj siab brittleness thiab yog nquag tawg. Nws yog tsim rau vuam cov ntaub ntawv uas muaj cov ntsiab lus alloy thiab tuaj yeem tsim cov txheej txheem metallurgical sib txuas nrog lub zog toughness. Lub solidified solder yog nruj nreem sib xyaw nrog cov tawv tooj liab bar substrate, uas tuaj yeem tiv thaiv kev co thiab hnav, tiv thaiv kev sib koom ua ke thiab kev tshem tawm, thiab txuas ntxiv kev pab cuam lub neej ntawm cov khoom siv.

Ntxiv cov solder tuaj yeem tiv thaiv qhov tsis xws luag xws li virtual soldering thiab txias soldering hauv Busbar rau ABB vuam los ntawm cov hauv paus hniav, thiab zam kev ua haujlwm tsis zoo. Qhov saum npoo ntawm cov tooj liab tawv tawv yog yooj yim tsim oxide zaj duab xis sai. Thaum cov tooj liab ntshiab yog welded ncaj qha, cov oxide txheej yuav cuam tshuam kev sib raug zoo ntawm tooj liab atoms. Cov khoom xyaw nquag muaj nyob rau hauv lub solder tuaj yeem decompose cov oxide nyob rau saum npoo ntawm cov tawv tooj liab bar, thaum cais cov huab cua los tiv thaiv oxidation theem nrab, kom ntseeg tau tias vuam fusion txaus.

Ntxiv cov solder tuaj yeem txo qhov melting point ntawm vuam thiab daws qhov teeb meem ntawm cov vuam tsis muaj zog los ntawm kev thermal conductivity ntawm hluav taws xob tooj liab busbars. Cov tooj liab tawv tawv muaj cov thermal conductivity zoo heev, thiab vuam cov cua sov tau yooj yim dissipated sai, ua rau nws nyuaj rau ncav cuag qhov zoo tshaj plaws vuam kub hauv zos. Direct welding yog qhov ua rau tsis txaus fusion. Lub melting point ntawm lub solder sib xws yog qis dua li ntawm cov ntshiab tooj liab, thiab nws muaj peev xwm yaj thiab nkag mus rau ntawm qhov kub thiab txias, pab tsim kev ruaj khov thiab txhim khu kev qha metallurgical kev sib txuas ntawm kev sib cuag ntawm cov tawv tooj liab bar.

Ua ntej siv solder rau fais fab busbar welding, nto pretreatment yuav tsum tau ua kom huv si tshem cov roj stains, oxide txheej, thiab impurities. Lub vuam nto ntawm cov tawv tooj liab tuaj yeem kho tau los ntawm kev siv tshuab polishing lossis tshuaj ntxuav kom huv si kom huv si thiab tso cai rau cov khoom siv kom nkag mus rau hauv thiab ntws sib npaug.

Thaum lub sij hawm vuam txheej txheem, nws yog ib qho tsim nyog yuav tsum tau tswj xyuas qhov kub thiab txias thiab lub sij hawm, hloov mus rau cov khoom ntawm cov tawv tooj liab bar thiab cov yam ntxwv ntawm cov solder, thiab tswj cov txheej txheem tsis. Qhov kub thiab txias dhau tuaj yeem ua rau cov khoom siv tsis tuaj yeem nkag mus rau qhov sib txawv ntawm cov tooj liab tawv tawv, thaum kub dhau heev tuaj yeem ua rau Busbar tooj liab substrate puas yooj yim thiab cuam tshuam rau kev ua haujlwm tag nrho.

Standardizing kev tswj ntawmtooj liab khoom tsheb npav barwelding txheej txheem thiab xaiv cov khoom tsim nyog solder yog cov tseem ceeb ua ntej kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov khoom siv fais fab. Yog tias koj muaj lus nug txog Bus bar hluav taws xob vuam ua, txheej txheem optimization, los yog xaiv solder, thov koj xav tiv tauj peb txhua lub sijhawm rau kev txhawb nqa kev tshaj lij.
