Muaj nuj nqi thiab hom busbars

 

Lub tsheb npav yog ib qho tam sim no - nqa tus neeg xyuas pib siv hauv cov chaw tsim hluav taws xob, chaw nres tsheb, thiab ntau lub zog xa hluav taws xob los txuas cov tshuab hluav taws xob, hloov pauv, thiab ntau yam khoom siv hluav taws xob. Nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv lub zog hluav taws xob, feem ntau yog siv daim ntawv hluav taws xob hluav taws xob lossis hluav taws xob Busbar.

 

Lub luag haujlwm tseem ceeb ntawm lub busbar yog sau, faib, thiab xa hluav taws xob hluav taws xob. Los ntawm lub busbar system, kev nkag mus rau hauv nruab nrab, hloov pauv hloov pauv, thiab cov khoom siv ruaj khov ntawm ntau lub zog tuaj yeem ua tiav, ua rau nws yog ib qho tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev xa tawm ntawm lub zog.

 

Los ntawm kev pom kev ua haujlwm zoo, lub kaw lus busbar feem ntau suav nrog cov khoom siv tseem ceeb ntawm cov tsheb thauj khoom, cov khoom siv txuas txuas, cov chaw nres tsheb AC busbars, DC system busbars, thiab cov busbars me me hauv nruab nrab. Hauv siab - cov ntawv thov tam sim no, busbars kuj ua haujlwm tseem ceeb ntawm Cov Txuas Txuas Tam Sim No thiab Cov Neeg Sib Txuas Siab Tam Sim No.

 

 

Los ntawm tag nrho cov qauv kev xav, busbars tuaj yeem muab faib ua peb pawg tseem ceeb: cov busbars raug kaw, kaw busbars, thiab insulated busbars. Cov qauv txheej txheem sib txawv muaj qhov sib txawv tseem ceeb hauv kev nyab xeeb, tam sim no - nqa peev xwm, siv qhov chaw, thiab kev saib xyuas.

 

 

Exposed busbars xa mus rau busbars uas raug ncaj qha rau huab cua, ruaj ntseg los ntawm huab cua rwb thaiv tsev thiab txhawb insulators. Lawv tau dav siv nyob rau hauv tsoos fais fab faib tshuab.

 

1. Kev faib tawm los ntawm Cov Khoom Siv

Copper busbars muaj qhov zoo tshaj plaws conductivity, siab mechanical zog, thiab zoo corrosion kuj. Cov ntaub ntawv muaj xws li Copper Busbars thiab Copper Solid Busbars. Vim yog tus nqi siab ntawm cov peev txheej tooj liab, tooj liab busbars feem ntau yog siv nyob rau hauv ib puag ncig corrosive los yog qhov chaw uas yuav tsum tau muaj tam sim no siab - nqa peev xwm, xws li thaj chaw ntug hiav txwv lossis thaj chaw muaj tshuaj lom neeg.

 

Aluminium busbars yog lub teeb yuag, qis - nqi, thiab muaj ntau yam kev pab. Lawv cov conductivity yog thib ob tsuas yog tooj liab, ua rau lawv siv dav hauv cov tshuab hluav taws xob sab hauv tsev thiab sab nraum zoov. Lawv yog ib qho ntawm feem ntau siv busbar tooj liab hom.

 

Aluminium alloy busbars feem ntau suav nrog ob hom: aluminium-manganese alloys thiab aluminium-magnesium alloys. Cov yav tas los muaj siab tam sim no - nqa lub peev xwm tab sis kuj tsis tshua muaj neeg kho tshuab lub zog, thaum tom kawg muaj lub zog txhua yam tab sis tsis zoo weldability, txwv nws daim ntawv thov ntau yam. Steel busbars muaj lub zog txhua yam tab sis tsis zoo conductivity, thiab feem ntau yog siv nyob rau hauv qis -tam sim no, siab -voltage, los yog grounding circuits, xws li hauv av bars.

 

2. Kev faib tawm los ntawm Hla -sectional Shape

Rectangular cross-section busbars yog siv nyob rau hauv 35kV thiab hauv qab fais fab faib tshuab. Lawv muab cov cua kub zoo, cov nyhuv tsis zoo ntawm daim tawv nqaij, thiab kev teeb tsa yooj yim thiab kev sib txuas, ua rau lawv muaj cov qauv tsheb npav hauv qis - thiab nruab nrab -voltage systems.

 

Circular cross-section busbars feem ntau yog siv hauv 110kV thiab siab dua -voltage sab nraum zoov systems. Lawv lub hom phiaj tseem ceeb yog txhawm rau tshem tawm cov kab mob corona thiab txhim kho kev ruaj ntseg; lawv yog cov qauv siab -voltage bus bar qauv.

 

Qhov -zoo li tus ntoo khaub lig- ntu busbars yog tsim rau siab - daim ntawv thov tam sim no, muab cov kev faib tawm tam sim no thiab kev siv hlau siab, ua rau lawv haum rau cov tshuab uas muaj kev ua haujlwm tsis tu ncua tam sim no.

 

Tube-zoo li tus ntoo khaub lig- ntu busbars feem ntau yog siv nyob rau hauv ultra- siab- cov tshuab tam sim no, muaj peev xwm ua kom sov tau zoo thiab muaj zog txhua yam, ua rau lawv yog ib qho tseem ceeb hauv high-tam sim no- nqa tsheb npav hluav taws xob hluav taws xob.

 

Stranded saj zawg zog busbars feem ntau yog tsim los ntawm multi-strand aluminium hlau los yog steel-cored aluminium stranded hlau. Haum rau sab nraum zoov siab - cov ntawv siv hluav taws xob, lawv tuaj yeem nqus cov kev ntxhov siab los ntawm thermal expansion thiab contraction thiab feem ntau yog siv rau kev sib txuas ntawm cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob.
 

 

Npog busbars yog lub tshuab busbar uas kaw cov neeg xyuas pib hauv lub casing. Lawv tau dav siv nyob rau hauv loj - muaj peev xwm generator teeb thiab tseem ceeb lub zog xa mus thiab faib cov nodes, thiab sawv cev rau ib tug tseem ceeb txoj kev loj hlob kev taw qhia rau niaj hnub Busbar Electrical systems.

 

1. Kev faib tawm ntawm cov Busbars Enclosed

Raws li cov khoom siv casing, lawv tuaj yeem muab faib ua cov yas-cased busbars thiab hlau-cased busbars.

 

Raws li theem- mus rau- theem qauv, lawv tuaj yeem muab faib ua cov tsis yog-theem- cais, theem- cais, thiab theem- cais cov npav kaw. Ntawm cov no, theem- sib cais cov busbars muaj ib qho kev ywj pheej hlau casing rau txhua theem tus neeg xyuas pib, muab kev nyab xeeb thiab kev ntseeg siab tshaj plaws.

 

2. Cov Txheej Txheem Txheej Txheem ntawm Theem -Separated Enclosed Busbars

Theem- cais cov busbars feem ntau muaj xws li tam sim no - nqa cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv tiv thaiv, cov khoom siv sib khi, cov khoom sib txuas, thiab cov khoom siv sib txuas. Hollow aluminium qauv feem ntau yog siv rau tam sim no - nqa cov khoom siv los txo cov tawv nqaij; Cov dej txias tuaj yeem siv los txhim kho tam sim no - nqa peev xwm nyob rau hauv ultra- cov xwm txheej tam sim no.

 

3. Cov yam ntxwv tshwj xeeb ntawm Theem-Sparated Enclosed Busbars

Theem-cov txheej txheem sib cais tau txo qis kev pheej hmoo ntawm theem- mus rau-theem luv circuits thiab txhim kho kev nyab xeeb kev ua haujlwm. Ib txhij, cov nyhuv shielding ntawm cov hlau casing zoo heev txo cov magnetic teb sab nraud thiab tshav kub tsim los ntawm steel Cheebtsam, txo qhov system poob. Cov qauv no yog qhov tsim nyog rau siab - lub zog, siab - kev ntseeg siab Power Bar BusBar daim ntawv thov.

 

Nws qhov tsis zoo suav nrog kev siv cov khoom siv ntau dua thiab cov nqi tsim khoom, thiab qhov muaj peev xwm txwv tam sim no - nqa peev xwm yog tias tus qauv tsim hluav taws xob tsis txaus.

 

 

Insulated busbars muaj cov conductors, ib txheej txheej rwb thaiv tsev, thiab cov qauv tiv thaiv. Cov conductors yog tag nrho encased nyob rau hauv insulating cov ntaub ntawv, sawv cev rau ib tug heev integrated busbar system.

 

Insulated busbars muaj tag nrho cov yam ntxwv ntawm rwb thaiv tsev, thiab theem - mus rau - theem nrug tsis txwv los ntawm qib voltage, txo qhov chaw teeb tsa. Qhov no ua rau lawv zoo tagnrho rau compact substations, underground substations, thiab rail transit systems.

 

Nws txoj kev sib txuas modular ua rau kev txhim kho yooj yim dua, tso cai rau kev hloov kho raws li qhov chaw nyob thiab zam qhov teeb meem tsis sib xws tam sim no tshwm sim los ntawm ntau cov kab sib txuas. Qhov no sawv cev rau txoj kev loj hlob tseem ceeb nyob rau hauv niaj hnub 3-theem busbar systems.
 

 

Nrog rau kev txhim kho cov khoom siv hluav taws xob tshiab, tsheb hluav taws xob, lub zog cia, thiab cov ntaub ntawv loj, cov kev xav tau siab dua tau muab tso rau ntawm qhov tam sim no - nqa peev xwm, kev nyab xeeb, thiab kev ntseeg siab ntawm cov tshuab busbar. Seb tsoosHluav taws xob tooj liab Busbarslos yog muaj kev sib koom ua ke thiab cov busbars insulated, lawv tau dhau los ua cov ntsiab lus tseem ceeb hauv siab - cov tshuab tam sim no.

 

Los ntawm qhov kev xav ntawm kev sib koom ua ke, busbars tsis yog tsuas yog cov khoom siv hluav taws xob nkaus xwb tab sis kuj tseem ceeb rau cov khoom siv sib txuas, kev ua kom zoo dua qub, thiab txhim kho kev ua haujlwm zoo. Lawv muaj tus nqi engineering uas tsis tuaj yeem hloov pauv hauv thaj chaw siab - tam sim no kev sib txuas thiab kev faib hluav taws xob.
