Tooj Busbar Science

abstract

tooj liab busbaryog ib qho khoom siv hluav taws xob tsis tseem ceeb rau kev tsim lub cev muaj zog windings, cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob, hloov kev sib cuag, thiab cov xov hlau rau kev teeb tsa hluav taws xob.

Copper Busbar Applications

Copper busbar yog ntau yam ntawm cov khoom siv tooj liab. Copper busbar muaj cov khoom siv kho tshuab siab, hluav taws xob zoo

conductivity, thermal conductivity, zoo heev corrosion kuj, electroplating, brazing, zoo nkauj metallic luster, zoo tsim thiab kev ua tau zoo, ntau yam fais fab kis thiab transformations, cov khoom siv hluav taws xob, thiab lwm yam ua los ntawm nws tau lug siv nyob rau hauv lub hwj chim teb. Nyob rau hauv xyoo tas los no, nrog txoj kev loj hlob tsis tu ncua thiab ceev ceev ntawm lub teb chaws kev lag luam, cov zis thiab kev siv ntawm tooj liab busbars hauv kuv lub teb chaws kuj tau nce ntau, thiab cov kev cai zoo rau tooj liab busbars kuj tau txhim kho tas li. Qhov zoo ntawm qhov cuam tshuam Qhov saum npoo zoo ntawm tooj liab busbar tuaj yeem muab faib ua peb yam tseem ceeb: nto smoothness, nto flatness, thiab deg defects. Nws yog inseparable ntawm tooj liab zog, ntau lawm txheej txheem, kev tswj, thiab ib puag ncig.

Cov yam ntxwv cuam tshuam rau qhov chaw tiav ntawm tooj liab busbar

Piv nrog rau lwm yam hlau, tooj liab muaj kev tiv thaiv corrosion zoo, tab sis nws tseem yuav raug hloov tshuaj nyob rau hauv qhov kub, av noo, acid pos huab, thiab lwm qhov chaw, uas ua rau cov xim tsis zoo. Hauv kev tsim khoom, khaws cia, thiab kev thauj mus los ntawm cov tooj liab busbars, cov xwm txheej tsis zoo no muaj nyob rau qib sib txawv, uas yuav muaj qee yam cuam tshuam rau qhov zoo ntawm qhov chaw.

kub

Nyob rau hauv ib puag ncig atmospheric,tooj liabyuav maj mam oxidize ntawm chav tsev kub; Thaum kub nce mus txog 100 degrees Celsius, dub tooj liab oxide pib tsim, thiab oxidation tus nqi yog proportional rau lub logarithm ntawm lub sij hawm; Thaum qhov kub nce mus txog 185 degrees Celsius, oxidation tus nqi nce ntau, thiab thaum kub nce mus txog 400 degrees Celsius, oxidation tus nqi yog txawm sai, nce nyob rau hauv parabolic yam.

av noo

Nyob rau hauv ib qho chaw ntub dej, muaj dej vapor ua rau tooj liab busbar nto corrode los yog oxidize. Thaum qhov kub thiab txias tsis tu ncua, qhov kev loj hlob ntawm cov oxide zaj duab xis nce nrog qhov nce hauv cov av noo.

Lubricant yam hauv cov txheej txheem kos duab

Lub luag haujlwm ntawm cov txheej txheem lubricants yog los txo kev sib txhuam, xyuas kom meej thiab txhim kho qhov zoo ntawm cov ntaub ntawv ua tiav, tiv thaiv cov hlau los ntawm cov pwm, thiab txias. Lubricants, residual acids, thiab cov dej seem seem nyob rau saum npoo ntawm cov tooj liab busbar thaum lub sij hawm tooj liab busbar txheej txheem yuav kuj ncaj qha los yog tsis ncaj qha cuam tshuam rau qhov zoo ntawm lub busbar tooj liab. Cov roj nplua nyeem zoo muaj lubricity zoo, thiab cov khoom seem ntawm cov tooj liab busbar yog lub hauv paus ua rau cov xim tsis zoo los yog cov cim corrosion ntawm cov tooj liab busbar.

Kev Txhim Kho Kev Ntsuas Zoo

1. Xyuas kom meej tias tus nqi yog qhuav, ntxiv dag zog rau lub melt cover, thiab txhim kho cov txheej txheem casting

Xyuas kom meej tias tus nqi qhuav tuaj yeem tiv thaiv cov dej noo hauv cov nqi los ntawm kev cuam tshuam nrog tooj liab los ua oxide inclusions thiab nqus hydrogen; ntxiv dag zog rau cov kev tiv thaiv yaj tuaj yeem tiv thaiv cov yaj los ntawm absorbing roj thiab oxidation, yog li tiv thaiv cov tooj liab busbar los ntawm kev tsim "hydrogen kab mob" los yog "oxygen kab mob" thaum lub sij hawm kho cua sov txheej txheem, ua rau nto defects xws li tev, npuas, inclusions, thiab lwm yam. tooj liab busbar nto; txheej txheem casting tsim nyog tuaj yeem tsis tsuas yog ua kom muaj txiaj ntsig ntau lawm, tab sis kuj txo qhov tsis xws luag xws li xoob, tawg, coarse nplej, thiab cais cov ntaub so ntswg, yog li txo cov kab nrib pleb, voids, thiab nto roughness ntawm tooj liab busbar nto, thiab txhim kho qhov zoo. ntawm tooj liab busbar.

2. Txhim kho cov txheej txheem kev tsim khoom thiab kev tswj xyuas ntau lawm

Txhawm rau txo qhov tsis xws luag ntawm cov tooj liab busbars, nws yog ib qho tseem ceeb kom ntxiv dag zog rau cov txheej txheem tswj thiab kev tswj ntau lawm.

3. Pickling ntawm tooj liab busbar blanks

Tom qab cov tooj liab ingot yog rhuab thiab extruded los ua ib tug tooj liab busbar dawb paug, muaj ntau ntau ntawm tooj liab oxide nyob rau saum npoo ntawm tooj liab busbar dawb paug vim cua sov, uas tsuas yog muab tshem tawm los ntawm cov txheej txheem pickling.

4. Kev xaiv zoo tshaj plaws thiab kev tsim nyog siv cov kub extrusion tuag thiab ncab tuag

Copper kub extrusion tuag ua hauj lwm nyob rau hauv hnyav high-kub tej yam kev mob thiab feem ntau siv hlau ceramic tuag uas muaj ob qho tib si ceramic zog (siab hardness, hnav tsis kam, kub-resistant, oxidation kuj, thiab corrosion kuj) thiab hlau zog (siab toughness thiab plasticity) .
