Lub neej ua haujlwm ib txwm uas kuv yuav tsum tau txais los ntawm lub davhlau ya nyob twg zoo 1500V DC hauv lub Hoobkas hnub ci hauv Is Nrias teb yog dab tsi?
Xaus Lus: Kev Qhia Txog Kev Cai Lij Choj Them Nyiaj Tau Zoo
Yog tias muaj ib yam uas kuv xav kom koj coj mus ntawm qhov kev tshaj tawm no, nws yog qhov no: qhov sib txawv ntawm kev ua tau zoo ntawm 1500V DC terminal block uas tau teev tseg kom raug thiab qhov tsis tau xaiv tsis yog tsuas yog ntsuas tus nqi ntawm cov khoom siv xwb, tab sis kuj tseem ntsuas kev poob ntawm tiam neeg, kev saib xyuas, thiab kev cuam tshuam IRR ntawm qhov project dhau 25 xyoo kev ua haujlwm.
Kuv tau qhia koj txog cov kev cai lij choj, kev sib piv cov khoom, cov ntaub ntawv xaiv, thiab cov lus qhia tshwj xeeb rau daim ntawv thov vim kuv ntseeg tias cov neeg qhia meej uas paub zoo ua rau cov haujlwm zoo dua. Thaum cov neeg tsim lub thawv sib txuas thiab cov neeg tsim cov haujlwm sib koom ua ke nkag siab zoo txog qhov zoo li cas, qhov tshwm sim yog cov nroj tsuag hnub ci zoo dua uas ua haujlwm raws li qauv.
Yog tias koj tam sim no nyob rau theem kev qhia tshwj xeeb rau qhov project hnub ci hauv Is Nrias teb thiab xav tham txog 1500V DC terminal block xaiv uas haum rau koj lub thawv combiner tsim, peb pab neeg ntawm Ningbo J Guang zoo siab los tshuaj xyuas koj cov kev xav tau thiab muab cov lus qhia txog kev siv tshuab. Koj tuaj yeem tshawb xyuas peb cov tiav ntau yam khoom, suav nrog peb cov Tsev neeg ntawm DIN rail terminal thiab Cov kev daws teeb meem txuas rau hnub ci tshwj xeeb uas ua kom tiav peb cov khoom siv davhlau ya nyob twg.
Kev hloov mus rau 1500V DC yog Is Nrias teb lub hnub ci yav tom ntej - thiab kev ua kom ntseeg tau tias cov khoom sib txuas ua tiav txoj haujlwm yog qee yam uas peb txhua tus yuav tsum tau ua tib zoo saib xyuas.
