Ua kom tiav cov lus qhia rau xaiv av tooj liab npav npav

Nyob rau hauv lub tshuab hluav taws xob, tooj liab tsheb npav rau hauv av yog qhov "kev ruaj ntseg txuas" cov khoom siv sib txuas thiab lub ntiaj teb. Lub laj thawj ntawm nws txoj kev xaiv ncaj qha cuam tshuam rau kev ua haujlwm ruaj khov ntawm cov khoom siv thiab kev nyab xeeb ntawm tus kheej, thiab cov tub ntxhais yuav tsum ua raws li plaub tus qauv loj. Kev coj tus cwj pwm yog qhov tseem ceeb hauv kev xaiv, thiab siab dua - cov khoom siv tooj liab zoo dua. Nws cov resistivity yog tsawg (txog 0.017 Ω· mm ² / m), uas tuaj yeem qhia qhov txhaum tam sim no rau hauv av. Yog tias qhov kub thiab txias (xws li 40 degree), nws yuav tsum tau muab xam kom raug siv cov qauv nqa tam sim no.

Nyob rau hauv cov nqe lus ntawm corrosion kuj thiab oxidation tsis kam, nyob rau hauv cov av noo thiab corrosive ib puag ncig (xws li tshuaj nroj tsuag thiab ntug hiav txwv dej), nto kho Grounding bar qhov yuav tsum tau xaiv. Tin plating, galvanizing thiab lwm yam txheej txheem tuaj yeem txo qhov kev pheej hmoo ntawm oxidation thiab txuas lub neej kev pab cuam. Nyob rau hauv cov nqe lus ntawm kev yooj yim installation, nws yog ib qhov tsim nyog los xaiv cov tooj liab tuav nrog adjustable ntev thiab txawv qhov chaw raws li qhov tseeb scenarios, uas yog yooj yim rau ntawm - site installation thiab adaptation. Hais txog tus nqi -kev ua tau zoo, nws yog qhov tsim nyog los sib npaug ntawm cov khoom nqa tam sim no thiab cov nqi nkag. Cov txheej txheem casting ntawm tooj liab tuav tau zoo heev tus nqi -effectiveness. Rau qis-voltage systems, tus qauv specifications ntawm 35mm ² thiab 50mm ² yuav siv tau, thaum rau siab-voltage systems, tooj liab tuav nrog ib tug ntoo khaub lig-sectional cheeb tsam ntawm 200mm ² los yog ntau tshaj yuav tsum tau xaiv.

Cov kev qhia tshwj xeeb ntawm cov tsheb npav hauv av tooj liab yuav tsum tau ua ke nrog lub peev xwm nqa tam sim no thiab cov qauv tsim nyog kom ntseeg tau tias muaj kev sib raug zoo nrog cov txheej txheem kev ua haujlwm. Kev kwv yees ntawm lub peev xwm nqa tam sim no tuaj yeem ua raws li txoj hauv kev yooj yim thiab siv tau: tam sim no nqa lub peev xwm ntawm ib kab tooj liab busbar tuaj yeem suav tau los ntawm kev sib npaug ntawm qhov dav los ntawm thickness coefficient. Piv txwv li, ib tug tooj liab busbar nrog ib tug dav ntawm 40mm thiab ib tug tuab ntawm 10mm muaj ib tug tam sim no nqa peev xwm ntawm txog 40 × 18=720A; lub peev xwm nqa tam sim no ntawm ob kab tooj liab busbar yog 1.56-1.58 npaug ntawm ib kab, thiab ntawm peb kab tooj liab busbar yog ob zaug ntawm ib kab; Qhov kub thiab txias muaj qhov cuam tshuam loj rau lub peev xwm nqa tam sim no, thiab lub peev xwm nqa tam sim no ntawm 40℃yuav tsum raug kho los ntawm kev muab tus nqi ntawm 25℃los ntawm 0.85.

Kev txhim kho kev tshawb fawb thiab kev saib xyuas tsis tu ncua yog qhov tseem ceeb los ua kom muaj txiaj ntsig ntawm Ground bus bar hluav taws xob vaj huam sib luag. Thaum lub sij hawm lub installation txheej txheem, nws yog tsim nyog los xyuas kom meej tias qhov chaw sib cuag ntawm lub tooj liab bar thiab lub grounding lub cev yog txaus thiab nruj nreem txuas. Thaum siv vuam lossis ntsia liaj qhov rooj, cov oxide txheej ntawm qhov chaw sib cuag yuav tsum raug tshem tawm ua ntej kom tsis txhob muaj kev tiv thaiv ntau dhau.

Copper busbars rau cov khoom siv hluav taws xob tsis cuam tshuam rau sab nraum zoov yuav tsum muaj kev rwb thaiv tsev thiab tiv thaiv - kev kho corrosion los tiv thaiv kev puas tsuaj los ntawm ib puag ncig. Nws tseem raug txwv nruj kom sib xyaw nrog cov tsis muaj kev cog lus hauv av xws li cov kav dej kom tsis txhob cuam tshuam rau hauv av.

Nyob rau hauv cov nqe lus ntawm kev saib xyuas, nws yog ib qho tsim nyog yuav tsum tsis tu ncua tshuaj xyuas lub tsheb npav tooj liab daim kab xev, ntsuas cov av tiv thaiv txhua 1-2 xyoo, thiab xyuas kom meej tias tus nqi tiv thaiv tsis ntau dua 4 Ω; Nyob rau tib lub sijhawm, tshawb xyuas qhov xoob, corrosion, lossis lwm yam teeb meem ntawm cov ntsiab lus txuas. Yog tias pom muaj cov khoom laus, lawv yuav tsum tau hloov raws sijhawm kom ntseeg tau tias lub sijhawm ua haujlwm ruaj khov ntawm cov av hauv av.

Muaj qhov sib txawv ntawm qhov yuav tsum tau ua rau Backplane tsheb npav tuav hauv cov xwm txheej hluav taws xob sib txawv, thiab kev xaiv cov hom phiaj yuav tsum tau ua raws li cov yam ntxwv ntawm qhov xwm txheej. Nyob rau hauv qhov xwm txheej ntawm qis- qhov hluav taws xob faib khoom, cov tooj liab nrog qhov loj ntawm 3 × 30mm ² tuaj yeem xaiv, nrog lub peev xwm nqa tam sim no kwv yees li 425A. Tus ntoo khaub lig-sectional cheeb tsam ntawm PE bar tau teeb tsa ua ib nrab ntawm tus ntoo khaub lig-sectional cheeb tsam ntawm theem kab thiab tsis tsawg dua 16mm ². Hauv qhov xwm txheej ntawm kev sib txuas lus hauv paus chaw nres tsheb, vim muaj cov av noo thiab lwm yam teeb meem ntawm ib puag ncig, nws raug nquahu kom siv cov tin plated tooj liab tuav nrog tus ntoo khaub lig- thaj tsam ntawm tsis pub tsawg tshaj 50mm ², thiab koom tes nrog kev tiv thaiv hluav taws xob thiab kev tsim hauv av kom txhim kho kev tiv thaiv.

Hauv cov khoom siv hauv kev lag luam, cov cuab yeej siv siab tam sim no xws li lub cev muaj zog yuav tsum tau siv ntau kab ntawm cov kab tooj liab sib xyaw lossis cov tooj liab tsis sib xws los xyuas kom meej tias Vertical tooj liab bonding busbar muaj qhov zoo thermal stability thiab ua tau raws li cov kev cai ntawm kev ua haujlwm siab tam sim no. Kev xaiv ntawm cov khoom siv tooj liab hauv av yog lub hauv paus ntawm kev siv hluav taws xob zoo. Nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog kev coj ua, kev hloov pauv ib puag ncig, thiab kev lag luam, xaiv cov khoom lag luam uas ua tau raws li lub teb chaws cov qauv, thiab ua qauv kev teeb tsa thiab kev saib xyuas txhawm rau tsim kom muaj kev ruaj ntseg tiv thaiv kab rau hluav taws xob.

Yog tias koj muaj lus nug lossis xav tau cov lus qhia xaiv lub hom phiaj thaum lub sijhawm xaiv cov txheej txheemHauv av tooj liab bus bar, thov koj xav tiv tauj peb txhua lub sijhawm. Peb yuav tso siab rau peb cov peev txheej kev tshaj lij los muab cov kev daws teeb meem txhim khu kev qha rau koj thiab pab koj ua tiav cov haujlwm xaiv.
