| Khoom siv | Conductivity (% IACS) | Conductivity (MS / m) | Lub peev xwm nqa tam sim no (tib yam ntoo khaub lig-section) |
|---|---|---|---|
| Tooj liab (C11000) | 100% | Ntau dua lossis sib npaug li 58 | 100% (qhov tseeb) |
| Aluminium (6061 / 1060) | 61-63% | 35-37 | Tsuas yog 61% ntawm tooj liab |
Qhov kev sib piv conductivity no yog raws li ASTM B187 thiab IEC 60143 tus qauv. To taubvim li cas xaiv tooj liab busbartshaj aluminium, nco ntsoov tias tooj liab nqatib yam tam sim no nrog 40% me me hla-sectiontshaj aluminium.

| Qhov xwm txheej | Tooj Busbar | Aluminium Busbar | Yeej |
|---|---|---|---|
| Qhov ceev (g / cm³) | 8.96 | 2.70 | Aluminium (67% sib dua) |
| Qhov hnyav rau tib lub ampacity (300A) | 1.0 kg ib | 0.45 kg ib | Aluminium |
| Raw khoom nqi ib kg | Lub hauv paus (1.0x) | ~0.30x | Aluminium |
| Raw khoom nqi rau tib ampacity | Lub hauv paus (1.0x) | ~0.35-0.40x | Aluminium |
Txawm li cas los xij, xav txog cov nqi ntxiv rau aluminium:
Loj dua qhov lojxav tau (ntau dua txee nqi)
Ntau zog rau installation(hnyav dua los tuav ib lub ampacity? Tsis yog - sib dua, tab sis sib txuas ntxiv)
Kev sib koom ua ke tshwj xeebxav tau rau txhua qhov kev sib txuas
Ntau zaus re-torquing(tus nqi kho dua 25 xyoos)
Siab dua tus nqi hloov(lub neej luv luv)
Thaum tshav kub kub yog tus yeeb ncuab ntawm cov tshuab hluav taws xob.Thaum tshav kub kub dissipation ntawm tooj liab busbaryog qhov zoo dua li aluminium.
| Khoom | Tooj Busbar | Aluminium Busbar | Qhov zoo |
|---|---|---|---|
| Thermal conductivity (W / m · K) | ~401 | ~235 | Copper (70% zoo dua) |
| Coefficient ntawm Thermal Expansion (µm/m·K) | 17 | 23 | Copper (tsawg expansion) |
| Creep nyob rau hauv thermal cycling | Tsawg (stable) | Siab (loosens dhau sijhawm) | Tooj |
Zoo duakub dissipation ntawm tooj liab busbartxhais tau hais tias qis kev ua haujlwm kub, tsis tshua muaj thermal stress ntawm cov khoom nyob ze, thiab txo kev pheej hmoo ntawm kev sib txuas loosening. Rautooj liab busbar siv nyob rau hauv hluav taws xob panels thiab switchgearnrog kev ceev ceev tam sim no, qhov no yog qhov tseem ceeb ntawm kev nyab xeeb.
| Qhov xwm txheej | Tooj Busbar | Aluminium Busbar |
|---|---|---|
| Oxide txheej conductivity | Kev coj ua- tsis nce kev tiv thaiv | Tsis yog -conductive- yuav tsum tau roj tshwj xeeb |
| Galvanic corrosion nrog hlau / tooj liab | Kev pheej hmoo tsawg | Kev pheej hmoo siab– xav tau kev cais |
| Kev ua tau zoo nyob rau hauv ntug hiav txwv ib puag ncig | Zoo (tin plating pom zoo) | Tsis zoo tsis muaj anodizing lossis txheej txheej tshwj xeeb |
| Hom lifespan (sab hauv tsev) | 30-50 xyoo | 15-25 xyoo |
Rautinned tooj liab busbars rau corrosion kuj, oxide txheej tseem ua tau. Aluminium oxide yog ib qho insulator, uas yog vim li cas txhua qhov kev sib txuas ntawm txhuas yuav tsum muaj cov tshuaj tiv thaiv antioxidant thiab tsis tu ncua re-torquing. Qhov no yog ib qho laj thawj tseem ceebvim li cas xaiv tooj liab busbarrau qhov tseem ceeb infrastructure.
Kev sib piv ntawm installation thiab tu
| Ua haujlwm | Tooj Busbar | Aluminium Busbar |
|---|---|---|
| Kev tu qhov chaw | Dej cawv so xwb | Hlau txhuam + antioxidant compound |
| Torque xav tau | Tus qauv (DIN EN 60947-1) | Siab dua + re-torque tom qab 24 teev |
| Re- lub sij hawm torque | Tsis xav tau | Txhua 12-24 lub hlis |
| Risk ntawm xoob kev twb kev txuas | Tsawg | Siab(ceeb + thermal expansion) |
| Cov cuab yeej tshwj xeeb lossis cov khoom sib xyaw uas xav tau | Tsis muaj | Yog lawm(oxide- txwv tsis pub roj) |
Ua raws li txoj caitooj liab busbar installation xyaumyog ncaj ncees. Aluminium xav tau kev cob qhia ua haujlwm thiab nruj torque raws tu qauv. Rau cov chaw uas tsis muaj cov neeg ua haujlwm kho hluav taws xob tshwj xeeb, tooj liab yog qhov kev xaiv zoo dua.
| Daim ntawv thov | Khoom siv pom zoo | Yog vim li cas |
|---|---|---|
| Cov chaw zov me nyuam (PDUs, busways) | Tooj | Tsawg tshav kub, txuag chaw, lub neej ntev (25+ xyoo) |
| Switchgear thiab vaj huam sib luag boards | Tooj | Kev ntseeg siab, kev saib xyuas tsawg dua, kev nyab xeeb |
| EV them chaw nres tsheb | Copper (hloov tau) | Kev vibration tsis kam, thermal cycling |
| Hnub ci fais fab nroj tsuag (sab nraum zoov) | Tooj | Corrosion kuj, 25-xyoo lifespan |
| Industrial MCCs (siab tam sim no) | Tooj | Cov cua kub zoo dua, kev sib txuas ruaj khov |
| Cov khoom siv hluav taws xob loj | Los yog- nyob ntawm pob nyiaj siv | Tooj liab rau qhov tseem ceeb feeders, aluminium rau tsis yog - tseem ceeb |
| Kev faib hluav taws xob ib ntus | Aluminium | Tus nqi qis, kev pabcuam luv luv (hauv qab 10 xyoo) |
| Tus nqi - tsav vaj tse nyob | Aluminium | Code- pom zoo rau qhov tsis tshua muaj tam sim no, sab hauv tsev nkaus xwb |
Rau qhov tseem ceeb infrastructure zoo litooj liab busbars rau cov chaw cov ntaub ntawv thiab cov chav serverlos yogtooj liab busbars rau grounding thiab bonding, tooj liab yog tus qauv kev lag luam. Rau qhov tsis yog - tseem ceeb, pob nyiaj siv - txwv cov haujlwm nrog lub neej luv luv, aluminium yog qhov siv tau.

Q1: Puas yog txhuas busbar muaj kev nyab xeeb siv hauv switchgear?
Yog, thaum ntsia zoo.Txawm li cas los xij, aluminium xav tauCov txheej txheem torque nruj, cov tshuaj tiv thaiv antioxidant, thiab re-torqueing tsis tu ncua.Kev sib txuas ntawm aluminium xoob yog qhov ua rau hluav taws xob hluav taws xob.
Q2: Kuv puas tuaj yeem txuas tooj liab busbar ncaj qha rau txhuas busbar?
Tsis ncaj.Tooj thiab txhuas ua ke ua raugalvanic corrosion kuj. Siv abi-cov khoom siv hlaulos yog tin -phaj ob qhov chaw.
Q3: Qhov twg zoo dua rau siab - daim ntawv thov tam sim no - tooj liab lossis txhuas?
Tooj.Zoo duakub dissipation ntawm tooj liab busbarthiab cov conductivity siab dua txhais tau tias tooj liab khiav txias dua thiab yuav tsum muaj qhov chaw tsawg dua. Rau cov tam sim no siab dua 800A, tooj liab tau pom zoo.
Q4: Puas yog txhuas busbar pheej yig dua tooj liab?
Yog, ua ntej.Aluminium nqi txog35-40% tooj liab rau ampacity. Tab sis qhov tseem ceeb ntawm cov ntaub ntawv loj dua, kev ua haujlwm ntau dua, thiab kev saib xyuas ntau dua - tag nrho cov nqi ntawm cov tswv cuab tshaj 25 xyoo feem ntau tsuas yog 10-20% tsawg dua.
Q5: Kuv yuav xaiv li cas ntawm tooj liab thiab txhuas rau kuv qhov project?
Siv qhov kev txiav txim siab ntws:
Lub neej expectancy> 15 xyoo? → Tooj
Tam sim no> 800A? → Tooj
Sab nraum zoov lossis ntug hiav txwv? → Tooj
Nyiaj txiag- tseem ceeb + sab hauv + tsis tshua muaj tam sim no? → Aluminiumtej zaum ua hauj lwm
