RMU vs Tag Nrho Switchgear, thiab Box Substation vs Built Room: A Practical Trade-Off
Ob lo lus nug tshwm sim hauv yuav luag txhua qhov kev hu thawj zaug. Thawj yog seb qhov nruab nrab-voltage point xav tau lub nplhaib tseem ceeb lossis ib qho kev hloov pauv tag nrho. Qhov thib ob yog seb tag nrho cov node yuav tsum tuaj raws li lub thawv, tuaj raws li ib prefabricated chav, los yog tsim ua ib lub cib faib chav rau ntawm qhov chaw. Ob lo lus nug yog txuas. Teb cov thawj thiab thib ob feem ntau nqaim nws tus kheej.
Tsab ntawv xov xwm no nthuav tawm cov kev lag luam tawm hauv cov ntsiab lus yooj yim: hneev taw, dab tsi tsav tus nqi, ceev npaum li cas txhua qhov kev xaiv tsa, thiab cov xwm txheej uas ib tus yeej. Peb tsim tag nrho nws, yog li tsis muaj cov lus teb zoo dua tsuas yog qhov koj qhov chaw xav tau.
Nplhaib lub ntsiab tiv thaiv tag nrho switchgear
Lub nplhaib tseem ceeb yog lub thawv ntim khoom sib cog ua rau cov kab hluav taws xob hluav taws xob thiab lub nplhaib-network nodes. JSGK muab lawv nyob rau hauv cov roj-insulated (GIS) kev npaj nrog load switching. Lawv yog cov me me, kaw ntom nti thiab txhais tau tias rau qee qhov tsawg ntawm cov kab hluav taws xob uas muaj kev tiv thaiv me me thiab qhov chaw nruj. Xav txog lub vaj tsev pub khoom vaj khoom tsev, lub voj voog hluav taws xob, lub tsev kawm ntawv cog lus.
Ib tug tag nrho high-voltage switchgear line-up yog ib tug txawv tsiaj. Nws yog KYN, XGN thiab lwm yam hlau-nyob rau hauv txee kab rau kev nkag, tawm, tiv thaiv thiab ntsuas schemes. Nws nqa ntau circuits, tiv thaiv ntau relays, ib tug tiag tiag busbar, thiab nplooj siab tuaj thiab metering txoj hauj lwm. Nws xav tau ib chav, ib qho kev nkag mus rau pem hauv ntej thiab kev saib xyuas tshem tawm.
Xaiv lub nplhaib tseem ceeb thaum lub luag haujlwm yooj yim: lub nplhaib ntawm lub nplhaib, ob peb lub qhov hluav taws xob, tsis tas yuav muaj kev tiv thaiv tag nrho thiab ntsuas ntsuas. Xaiv tag nrho cov hloov pauv hloov thaum chav hloov pauv hloov pauv, lub cev muaj zog lossis cov nroj tsuag, thaum muaj kev tiv thaiv qib tseem ceeb, thiab thaum muaj pes tsawg lub voj voog loj hlob tuaj.
Kev lag luam tawm hauv ib kab: RMU yuav koj compactness thiab ceev, lub switchgear yuav koj Circuit Court suav thiab tiv thaiv qhov tob.
Lub thawv substation piv rau chav tsev faib khoom hauv tsev
Tam sim no lo lus nug thib ob. Lub thawv-hom substation integrates lub transformer, lub high-voltage txee, low-voltage txee, lub enclosure thiab auxiliary systems rau hauv ib chav tsev sab nraum zoov. Nws tuaj txog ntawm lub tsheb thauj khoom, zaum ntawm lub hauv paus me me, thiab txuas rau ntawm qhov chaw.
Ib chav tsev faib khoom ua rau ntawm qhov chaw yog txoj hauv kev ib txwm muaj: chav tsev pob zeb lossis cib tsim los ntawm qhov project, tom qab ntawd muab tso rau hauv cov txee, tsheb npav, qhov cua thiab kev tiv thaiv hluav taws los ntawm qhov chaw lag luam.
Lub thawv-hom substation yeej ntawm hneev taw thiab commissioning ceev. Nws nyob hauv lub ncoo me me, xav tau kev ua haujlwm me me, thiab raug kuaj xyuas ua ntej nws tawm mus, yog li kev ua haujlwm feem ntau yog cabling thiab lub zog. Nws yog lub neej ntawd rau kev faib tawm sab nraum zoov, qhov chaw tshiab-zog thiab cov haujlwm ntawm lub moos.
Cov chav ua tau yeej ntawm kev yoog raws thiab ruaj khov. Yog tias koj cia siab tias cov khoom yuav loj hlob nyob rau hauv cov lus qhia tsis paub, yog tias lub xaib muaj av ntau, lossis yog tias cov khoom siv hluav taws xob xav tau chav nyob ruaj khov, qhov chaw tsim kho tuaj yeem nthuav dav thiab rov kho dua. Nws cov nqi yog tsav los ntawm kev ua haujlwm hauv pej xeem, kev lag luam ntub dej thiab kev txawj ua haujlwm uas yuav tsum tau tshwm sim hauv huab cua qhib, huab cua tso cai. Nws commissioning yog qeeb qeeb vim lub tsev, ces lub installation, tshwm sim nyob rau hauv ib ntus.
Qhov sib txawv commissioning yog qhov uas cov neeg yuav khoom xav tias qhov kev xaiv feem ntau. Lub thawv substation lossis alarm yog lub Hoobkas kuaj ua ntej nws yuav nkoj, yog li qhov chaw ua haujlwm yog lub hauv paus, kev tso kawm, cable txiav thiab energisation. Ib chav tsev ua tau nqa lub nra hnyav ntawm qhov chaw, tom qab cov phab ntsa tau nce thiab cov txee tau teeb tsa, uas ntxiv rau lub lis piam thiab nthuav tawm lub sijhawm rau huab cua thiab rau cov neeg ua haujlwm muaj nyob. Nyob rau hauv ib qhov project nrog rau lub sij hawm energisation, qhov sib txawv ib leeg feem ntau txiav txim siab xaiv.
Qhov kev xaiv nruab nrab: lub prefabricated hluav taws xob cabin
Muaj ib txoj hauv kev thib peb cov neeg yuav khoom saib. Lub tsev hluav taws xob prefabricated yog lub Hoobkas tsim hluav taws xob chav rau switchgear, kev tiv thaiv vaj huam sib luag thiab cov cuab yeej pabcuam. Nws yog loj dua lub thawv substation tab sis xa tib txoj kev: ua, xaim, kuaj thiab ntim ntawm peb cov nroj tsuag, ces xa tuaj raws li qhov hloov pauv tau.
Lub tsev nyob nruab nrab ntawm ob lub siab. Nws muab koj chav zoo li kev teeb tsa thiab nkag mus rau pem hauv ntej ntawm chav tsev faib khoom, tab sis nrog kev txhim kho sai thiab tsawg kawg ntawm qhov chaw ua haujlwm ntawm lub Hoobkas khoom. Chav nyob tuaj txog lub Hoobkas npaj heev; nyob rau ntawm qhov chaw lawv bolt ua ke thiab txuas, nrog deb tsawg tshaj li kev lag luam ua haujlwm. Lawv tau tsim los hloov chaw thiab rov siv tau, uas yog qhov tseem ceeb thaum qhov project khiav rau xyoo thiab tom qab ntawd demobilises.
Xaiv lub thawv substation rau lub compact, sab nraum zoov, transformer-plus-switchgear node. Xaiv lub tsev prefabricated thaum koj xav tau chav hloov pauv tiag tiag tab sis tsis tuaj yeem tos lub cib tsim. Xaiv chav nyob rau ntawm qhov chaw tsuas yog thaum lub layout yog tiag tiag, av yog pheej yig thiab lub sij hawm tso cai rau ntub dej pej xeem ua hauj lwm.
Tus nqi tsav tsheb kom hnyav thaum ntxov
Tus nqi tsis nyob hauv tus nqi txee ib leeg. Nrog rau lub thawv substation lossis alarm, koj tau them nyiaj rau lub Hoobkas npaj, ntim cov khoom xa tawm thiab cov hneev taw me me, thiab txuag kev ua haujlwm hauv pej xeem thiab chaw ua haujlwm. Nrog rau chav tsev tsim, koj pauv cov khoom siv me me rau kev ua vaj tse, vov tsev, qhov cua, hluav taws ua haujlwm thiab lub qhov rais siv ntev. Freight kuj tseem ceeb: lub thawv substation thiab cabin ntim kom nruj rau kev xa tawm, uas txo tus nqi xa tawm ntawm ib qho ntawm qhov chaw deb lossis txawv teb chaws.
Thaum txhua qhov kev xaiv yeej
- RMU: ring-network nodes, compact cable outlets, txwv lub luag hauj lwm tiv thaiv.
- Tag nrho switchgear: nroj tsuag, substations, ntau outgo feeders, tiv thaiv grading yuav tsum tau.
- Box-type substation: Sab nraum zoov faib cov nodes, qhov chaw tshiab-zog, muaj zog ceev.
- Prefabricated chav tsev: ib chav switchgear xav tau sai sai, los yog ib qhov chaw uas yuav tsum tau tom qab hloov chaw.
- Built-in-site chav: ruaj ruaj layout, txaus av, tsis muaj sij hawm siab.
Xa peb hom ntawm node, lub peev xwm transformer, tus naj npawb ntawm cov hluav taws xob tawm thiab qhov chaw ib puag ncig. Peb yuav qhia tias qhov kev xaiv twg haum rau tus hneev taw, moos thiab pob nyiaj siv, thiab hais nws lub Hoobkas ncaj qha.
