1. Tib transformer busbar cov khoom lag luam
Transformer busbars feem ntau yog faib cov khoom lag luam busbars (xws li tooj liab carloy (xws li copstream hom hauv lub zog nrog cov ntsiab lus raws li nram no:
Tooj liab busbars yog ua los ntawm tooj liab (nrog cov cim tooj liab bars lossis ntau li ntau dua 220k thiab ntau dua li cov hloov hluav taws xob loj) thiab ntau dua li cov hluav taws xob loj.
Aluminum busbars are made of pure aluminum (with aluminum content of 99.0% or more) or low-alloy aluminum and usually exist as rectangular aluminum bars or aluminum tubes and they are low in cost and lightweight mainly used in medium-low voltage medium-small current scenarios (such as 10kV distribution transformers transformers for residential buildings).
Tooj liab -}} Cov roj hmab uas tau txais txiaj ntsig zoo li cas rau kev coj ua thiab cov khoom siv tooj liab tau ua kom zoo dua qub) Nruab nrab-loj hloov pauv hloov pauv rau cov hluav taws xob hluav taws xob tshiab).
2. Cov yam ntxwv ntawm cov busebars ua los ntawm cov khoom sib txawv
Busebars ntawm cov khoom sib txawv muaj qhov sib txawv ntawm kev ua haujlwm zoo nkauj thiab corrosion resistance uas cuam tshuam rau lawv daim ntawv thov kev sib piv nrog cov ncauj lus sib piv raws li nram no:
1. Kev ua tau zoo
Tooj liab busbars muaj cov kev ua haujlwm siab heev (tiv taus li 0.01722}}} pa taws tshiab (piv txwv li ntau yam ntawm amperes) thaum txo lub zog khib nyiab tshwm sim los ntawm kev siv hluav taws xob zoo.
Aluminium Busbars muaj qis dua tooj liab (REWANTION ANCEs thiab lawv xav tau ib qho kev sib npaug ntawm tus nqi (txog 1.5} Cov xwm txheej.
Tooj liab -}}} Aluminium composter thiab cov khoom siv tooj liab tau muaj kev sib ze ntawm 0.5-4a / mm² uas yog nruab nrab ntawm tooj liab thiab Aluminium busbars thiab ua tiav qhov sib npaug ntawm kev ua tiav thiab tus nqi.
2. Cov Tshuab Kho Tshuab
Tooj liab busbars muaj siab tensile lub zog (txog 200 {}}}} Kev them nyiaj yug xws li sab nraum zoov hloov transformer busbars thiab cov hluav taws xob siab hloov hluav taws xob siab.
Aluminium busbars muaj qis dua zog (xws li nws muaj peev xwm ntxiv rau cov qauv sib txuas ntxiv nrog rau kev hloov chaw nyob sab nraud.
COPPER {{0 {}}}}} kov cov txheej thiab aluminium thiab tag nrho cov kev ntsuas tooj liab uas yuav tsum muaj dua los ntawm kev txhawb nqa me me thiab txiav txim siab rau feem ntau cov kev siv voltage.
3. Nqi
Tooj liab busbars muaj cov khoom siv remin yog li ntawm 2.5-4 zaug ntawm cov kev xav tau ntawm Aluminium thiab lawv tus nqi qis dua xws li cov hluav taws xob tseem ceeb hauv cov nroj tsuag hluav taws xob loj.
Aluminium Busbars muaj cov khoom siv raw tsawg thiab lawv tau tsim nyog rau tus nqi ntawm cov nqi ntawm ib qho ntxiv xws li cov neeg xa khoom tsis muaj zog xws li xa cov hloov chaw thiab cov hluav taws xob.
Topper -} Cov nqi Busbars thiab 30% siab dua li 80}}}} Tus nqi-ua tau zoo dua li cov khoom thauj khoom uas cov khoom siv.
4. Corrosion Kuj
Tooj liab Busbars tau tsim cov yeeb yaj kiab tuab (xws li cov av me me (xws li cov dej hiav txwv (xws li Tin plating anti -} corrosion pleev xim).
Aluminium Busbars yooj yim tsim cov yeeb yaj kiab oxide uas yuav tsum tau ua rau muaj qhov tsis muaj zog thiab ua kom muaj qhov tsis txaus ntseeg thiab ua rau lawv muaj qhov tsis yooj yim dua Siab - corrosion ib puag ncig.
Copper -}}} Txhij cov txheej txheem corrosive thiab tsis tshua muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev tiv thaiv corrosive thiab tsis muaj kev sib cuag Thaj chaw vaum thiab tsuas yog kev tiv thaiv yooj yim (xws li qhwv nrog anti - corrosion daim kab xev) yog qhov yuav tsum tau rau kev txiav thiab pob qij txha.
