Hauv kev ua haujlwm hluav taws xob, kev ua kom zoo dua qhov kev faib hluav taws xob thiab kev ua haujlwm kom du yog qhov tseem ceeb heev. Ib qho khoom uas ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov hom phiaj no yog lub terminal busbar. Lub cuab yeej tshiab no ua haujlwm ua lub kaw lus faib hluav taws xob, pab xa hluav taws xob kom zoo thiab ua tau zoo hauv ntau yam kev siv. Hauv cov blog no, peb yuav nkag mus rau hauv lub ntiaj teb ntawmcov chaw nres tsheb kawgthiab tham txog lawv qhov tseem ceeb hauv cov txheej txheem hluav taws xob niaj hnub no.
1. Nkag siab txog lub terminal busbar:
Cov busbars kawg yog cov pas nrig conductive khov kho uas ua haujlwm ua qhov sib txuas ntawm cov chaw muab hluav taws xob thiab cov khoom thauj hauv cov kab ke faib hluav taws xob. Lawv lub luag haujlwm tseem ceeb yog xa hluav taws xob los ntawm ib qho chaw mus rau lwm qhov kom zoo thiab muaj kev nyab xeeb. Cov pas nrig hlau no feem ntau yog ua los ntawm tooj liab lossis txhuas zoo, xaiv rau lawv cov conductivity zoo heev thiab ruaj khov.
2. Qhov tseem ceeb ntawm lub tsheb npav hauv kev faib hluav taws xob:
a) Kev hloov fais fab zoo dua: Cov chaw nres tsheb muab cov kev siv fais fab uas tsis tshua muaj zog, txo qhov poob fais fab thiab ua kom muaj kev hloov fais fab ntau tshaj plaws. Lawv lub peev xwm nqa tam sim no siab ua rau kev hloov fais fab yooj yim, txo qhov poob hluav taws xob thiab ua kom lub kaw lus ua haujlwm tau zoo dua.
b) Tsim qauv me me thiab txuag chaw: Cov kab tsheb npav kawg muab kev xaiv me me thiab txuag chaw rau cov kab ke hluav taws xob ib txwm muaj. Los ntawm kev sib txuas ntau cov xov hlau tawm thiab cov xov hlau nkag mus rau hauv ib kab, lawv ua kom yooj yim rau kev teeb tsa hluav taws xob thiab ua kom yooj yim rau cov txheej txheem teeb tsa. Qhov kev tsim qauv no txuag tau qhov chaw muaj nqis, txhim kho kev nkag mus rau hauv lub kaw lus, thiab txhim kho kev zoo nkauj tag nrho.
c) Kev ua haujlwm thermal zoo dua: Qhov chaw loj dua ntawm lub tsheb npav davhlau ya nyob twg pab tshem tawm cov cua sov tsim thaum lub sijhawm xa hluav taws xob. Nws cov cua sov ua haujlwm zoo tiv thaiv cov teeb meem overheating thiab ua kom muaj kev ua haujlwm ruaj khov txawm tias nyob hauv cov khoom siv hluav taws xob siab.
d) Kev ywj pheej thiab kev nthuav dav: Qhov kawgcov busbarsmuab kev ywj pheej tsis muaj qhov sib piv hauv kev tsim qauv, tso cai rau lawv hloov kho rau ntau yam kev siv thiab kev teeb tsa. Lawv tuaj yeem hloov kho tau yooj yim rau kev hloov pauv thiab kev nthuav dav ntawm lub kaw lus hluav taws xob, ua rau kev nthuav dav yooj yim yam tsis cuam tshuam rau tag nrho cov khoom siv.
3. Cov ntawv thov siv tau ntawm cov davhlau ya nyob twg busbars:
a) Lub tshuab faib fais fab: Cov chaw nres tsheb yog lub hauv paus tseem ceeb ntawm cov tshuab faib fais fab hauv kev lag luam xws li kev tsim khoom, lub zog rov ua dua tshiab, cov chaw khaws ntaub ntawv thiab cov tsev loj. Lawv pab txhawb kev ntws hluav taws xob los ntawm lub hauv paus fais fab mus rau ntau yam khoom thauj, ua kom ntseeg tau tias muaj kev muab hluav taws xob txhim khu kev qha thiab ruaj khov.
b) Cov Rooj Tswj thiab Cov Vaj Huam Sib Luag: Cov chaw nres tsheb kawg ua lub luag haujlwm tseem ceeb hauv cov rooj tswj thiab cov vaj huam sib luag, txuas cov khoom siv sib txawv, cov khoom siv hluav taws xob thiab cov hloov pauv. Nws tus qauv tsim me me ua rau muaj kev teeb tsa zoo thaum yooj yim rau kev saib xyuas thiab kev daws teeb meem.
c) Tsheb fais fab: Thaum lub ntiaj teb txav mus rau kev ruaj khov, cov tsheb fais fab (EVs) tab tom nrov zuj zus. Lub tsheb npav kawg yog ib feem tseem ceeb ntawm lub tshuab them hluav taws xob, ua kom muaj kev sib kis hluav taws xob zoo ntawm qhov chaw them thiab lub tsheb.
4. Xaiv lub busbar davhlau ya nyob twg kom raug:
Thaum xaiv cov terminal busbars, cov yam xws li rated tam sim no, voltage theem, luv-circuit withstand peev xwm, rwb thaiv tsev ua haujlwm thiab cov xwm txheej ib puag ncig yuav tsum tau xav txog. Ua haujlwm nrog cov kws ua hluav taws xob thiab cov chaw tsim khoom kom paub tseeb tias qhov kev daws teeb meem terminal bus yog rau koj daim ntawv thov tshwj xeeb.
Hauv kev xaus lus:
Cov terminal busbars tau hloov pauv txoj kev faib hluav taws xob, muab cov kev daws teeb meem txhim khu kev qha, ua haujlwm tau zoo thiab txuag chaw rau kev xa hluav taws xob hauv ntau yam kev siv. Lawv lub peev xwm los txhim kho kev xa hluav taws xob, ua kom yooj yim rau kev teeb tsa, pab txhawb kev nthuav dav thiab xyuas kom meej tias muaj kev ua haujlwm thermal ua rau lawv yog ib qho tseem ceeb ntawm cov tshuab hluav taws xob niaj hnub. Los ntawm kev nkag siab txog nws qhov tseem ceeb thiab siv nws cov txiaj ntsig, cov engineers tuaj yeem tsim cov khoom siv hluav taws xob uas muaj zog thiab muaj zog uas muaj peev xwm ua tau raws li qhov xav tau hluav taws xob hloov pauv ntawm yav tom ntej.
