Dab tsi yog lub nplhaib tseem ceeb siv rau?
1.What yog lub nplhaib lub rooj zaum siv rau?
Ib lub nplhaib sab tseem ceeb (RMU) muaj cov chav nyob ntawm cov tib neeg. Nws txuas rau lub nplhaib Circuit Court uas tuaj yeem muab los ntawm ib lossis ob qho xaus los ntawm ib qho lossis ob lub zog. Qhov kev teeb tsa no tsim kev rov ua dua rau cov hluav taws xob. Yog tias ib lub zog tsis ua tiav, lub nra tuaj yeem tseem tuaj yeem muab los ntawm lwm qhov kawg, yog li txhim kho kev txhawb nqa hluav taws xob.
2.How yog cov khoom qauv npe hu ua?
Thaum pib ua tiav raws li "Kev Sib Tham," Cov khoom no muaj nuj nqis, taag kev teeb tsa zoo li CCV thiab CCVV, uas tsis nthuav dav. Hauv kev teb rau kev ua lag luam xav tau rau cov kev xav tau rau lub ntsuas phoo, abb tawm tsam "Adaloplus," lub tsev raws li kev sib tham ntxiv kom muaj peev xwm txuas ntxiv thiab cov koog ntxiv. Yog li, cov kab kab yog tam sim no sib sau ua ke nrog kev nyab xeeb / kev nyab xeeb.
3.Qhov cov khoom lag luam twg?
Kev Lom Zem / Nyab Xeeb muaj ntau lub tsev kawm ntawv, tab sis ob peb ntawm chav tsev feem ntau yog C, F, V thiab de

Feem ntau, covC moduleyog siv rauCov Khoom Noj Khoom TuajHauv RMU, thaumF thiab V Modulesyog siv rauyam rislossisT - tawm pub rau khoom nojCov. Qhov no feem ntau vim tias C module yog qis dua tus nqi thiab tsis suav nrog kev tiv thaiv kev tiv thaiv. Hauv kev sib piv, ob F thiab V Modules muab kev tiv thaiv; tusF moduletso siab rau fuses, thiab covV moduleSiv cov breaker breaker, ua rau nws siab dua - tus nqi xaiv.
Tam sim no, nyob rau hauv qee thaj chaw txawv teb chaws nrog qib qis dua ntawm kev siv tshuab thiab tus nqi siab dua rhiab, tusF moduletseem muaj ntau yam. Txawm li cas los xij, hauv kev lag luam tsim ntau dua (piv txwv li, Saudi Arabia, Europe), f module tau phased tawm vim nws tsis tuaj yeem txhawb nqa Automation. Niaj hnub nimno {- Tus phooj ywg roj -} Insulated rmus feem ntau tsis muab rau f module.
Nws yog ib qho tseem ceeb kom nco ntsoov tias tusC / F / V Litinology yog Ameslikas qhia los ntawm abbCov. Lwm cov tuam ntxhab xws li Schemer Electric thiab Siemens muaj lawv tus kheej tis npe rau RMU modules. Txawm li cas los xij, vim tias muaj ntau tus neeg tsim khoom hauv nroog ntawm Abb lub tswvyim, C / F / V kev tsim qauv tau dhau los ua kev lag luam.
4.Yog dab tsi muaj?
Feem ntau, rau cov tuam txhab zoo li abb thiab schneider hluav taws xob, cov kev thov siab los ntawm cov neeg siv khoom tuaj yeem ua rau cov nqi khoom lag luam. Yog li ntawd, lawv ib txwm ua ntej ntau yam ntawm cov qauv kev teeb tsa. Yog tias ib tus neeg yuav khoom siv tau cov kev daws teeb meem loj, cov phiaj xwm zoo li no yuav raug muab rau cov kws tsim khoom lag luam ua haujlwm.
Txawm li cas los xij, nyob hauv Suav teb lub zog kev lag luam, ntiv nplhaib cov khoom tseem ceeb (rmus) feem ntau haum rau cov kev thov kev hloov kho tshiab. Cov qauv piv txwv suav nrog kev hloov pauv tau (pts) ntawm cov kab ntawv kab lossis txhim kho pursingbar.

ABB qhov teeb meem tag nrho yog zoo - batanced, txawm hais tias ib co yog hais tias tsawg. Piv txwv li cov neeg kho tshuab kom ntev rau kev hloov pauv thiab hloov lub ntiaj teb yog feem ntau ntsuas rau tsuas yog 1,000 kev ua haujlwm nkaus xwb.
Nws yog ib qho tseem ceeb kom nco ntsoov tias kev nyeem ntawv / nyab xeeb platform yog ib qho khoom kab npog 12kV, 17.5KV kev ntsuas, thiab 24kV ntsuas. Qhov no txhais tau tias txawm tias ib chav teev tau tsim los ua kom tau raws li cov kev xav tau rau 24kv, xws li 125kv xob laim siab. Txawm li cas los xij, vim qhov sib txawv hauv kev tsim cov txheej txheem, ntau yam kev ua haujlwm hauv kev ua tiav 24kv rwb thaiv tsev ua haujlwm hauv lawv 12kv- rated khoom.
Ib yam li ntawd, hais txog Arc muaj, ABB tus qauv yog xws li tias tag nrho 25ka / 1S kev ntsuam xyuas tsuas yog ua tiav thaum lub Apard ARC venting channel nruab nrab. Nrog cov cable trench nyem ib leeg, txoj kev ntsuam xyuas yog 20ka / 1s.
Txawm hais tias no 20ka / 1s sab hauv Arc ntsuam xyuas yog ib yam ntau cov tuam ntxhab hauv Tuam Tshoj tawm tsam kom tau raws li kev xyaum.
6.technical ua tau zoo thiab tsis muaj zog
Zuag qhia tag nrho, cov khoom no muaj cov khoom zoo - balanced tsim thiab tus nqi qis, uas yog qhov tseem ceeb rau nws thoob plaws Suav teb. Txawm li cas los xij, nrog kev tshwm sim ntawm cov khoom sib tw, ob peb ntawm nws cov teeb meem tau dhau los sib tw. Piv txwv li:
Qhov kev ntaus nqi tam sim no rau covF (hloov - fuse) Chavyog txwv rau125A, whereas cov khoom sib tw feem ntau muaj200A.
TusCable installation qhov siabyog xwb595 hliCov. Lwm hom feem ntau muab tsawg kawg700 hli, uas muaj cov tswv yim tseem ceeb rau kev - chaw ntawm kev khoov.
Nws tsis muaj aDedicated Cable Chaw nres nkojCov. Kom ua Cable kev sim ua ntej, lub qhov rooj sib sau yuav tsum tseem qhib, thiab ib qho tshwj xeebCable Bushing (Bushing)yuav tsum tau. Hauv kev sib piv, feem ntau cov neeg sib tw muaj tshwj xeeb cable kev hloov pauv, ua txoj haujlwm kom yooj yim dua.
