1. Ring Main Unit yog dab tsi?
CovLub nplhaib Main Unit (RMU), kuj hu uaBox Hom Switchgear, yog ib hom compact, hlau- kaw switchgear feem ntau siv nyob rau hauv nruab nrab voltage tis systems (feem ntau 10kV–35kV). Nws koom ua ke cov khoom tseem ceeb xws li cov hloov pauv, fuses, thiab cov hluav taws xob hluav taws xob rau hauv ib qho, kaw hlau txee.
Tsis zoo li cov qauv hloov pauv, RMU tau tsim tshwj xeeb los tswj ob qho tib si cov khoom thauj tam sim no thiab covvoj - dhau tam sim no- qhov tam sim no uas dhau los ntawm chav tsev los muab cov ntsiab lus xa tawm nyob ib sab hauv lub nplhaib network. Qhov kev teeb tsa "ntiv nplhaib" no ua kom ntseeg tau tias lub zog tuaj yeem raug pub los ntawm ob qho kev qhia, ua kom muaj kev ntseeg tau ntawm lub zog. Yog hais tias ib lub hwj chim tsis ua hauj lwm, lwm tus tuaj yeem tswj tau seamlessly.
2. Vim li cas thiaj xaiv Ring Main Units?
Hauv cov ntawv thov xws li cov neeg nyob hauv zej zog, cov tsev siab - nce siab, thiab cov chaw ua si, cov peev txheej thauj khoom feem ntau yog nruab nrab. CovBox hom switchgearmuab qhov zoo sib npaug ntawm tus nqi -kev ua tau zoo thiab kev ntseeg tau. Cov txiaj ntsig tseem ceeb muaj xws li:
Kev ntseeg siab:Lub nplhaib network qauv tso cai rau ob- qhov chaw siv hluav taws xob, txo qis qis qis.
Compact Structure:Nws cov hneev taw me me txuag qhov chaw muaj txiaj ntsig hauv cov chav faib hauv nroog thiab prefabricated substations.
Kev nyab xeeb:Nrog tag nrho cov ntaub thaiv npog (feem ntau SF6 insulated los yog cov khoom insulated), nws tiv thaiv ib puag ncig cov kab mob thiab ua kom cov neeg siv kev nyab xeeb.
Integrated Protection:Kev sib txuas cov khoom siv hluav taws xob nrog siab -voltage fuses muab kev tiv thaiv kev txuag hluav taws xob thiab ua haujlwm zoo.
3. Daim ntawv thov Scenarios
RMU yog siv dav hauv cov chaw thauj khoom uas xav tau kev faib tawm siab. Cov ntawv thov ib txwm muaj xws li:
Cov zej zog nyob hauv nroog:Ua kom muaj zog ruaj khov rau cov khoom siv hauv tsev thiab teeb pom kev zoo.
High-Rise Buildings & Commercial Complexes:Txuag qhov chaw thaum ua tau raws li qhov xav tau siab - lub zog ceev.
Industrial Parks & Factories:Tiv thaiv kev faib tawm transformers thiab ua kom yooj yim txij nkawm.
Box-Tom Substations (Compact Substations):Ua raws li cov tub ntxhais nkag thiab tawm hauv chav tsev prefabricated.
Public Infrastructure:Cov tshav dav hlau, chaw nres tsheb subway, thiab cov chaw nres nkoj uas lub zog txuas ntxiv tseem ceeb heev.
4. Technical Structure & Hom
Box hom switchgearFeem ntau muaj nyob rau hauv ob hom rwb thaiv tsev tseem ceeb kom haum rau qhov chaw ua haujlwm sib txawv:
| Hom | Rwb thaiv tsev nruab nrab | Nta |
|---|---|---|
| Huab cua-Insulated RMU | Cua | Kev lag luam, pom qhov sib txawv ntawm qhov sib txawv, haum rau cov chaw sab hauv tsev. Xws li cov pa roj- tsim, huab cua-pressurized, thiab lub tshuab nqus tsev hom. |
| SF6-Insulated RMU Cov | SF 6 Gas | Compact, tag nrho kaw, txij nkawm-dawb, kev ua tau zoo nyob rau hauv ib puag ncig hnyav (humidity, pollution). Muaj 3-txoj hauj lwm (txuas, disconnects, earthed) functionality. |
Niaj hnub nimno RMUs feem ntau feature apeb - txoj hauj lwm hloov(Load Break, Disconnect, thiab Earth) kom yooj yim interlocking thiab ua kom muaj kev nyab xeeb. Rau lub tshuab nqus tsev contactor qauv, ib qho kev sib txuas ntxiv yog feem ntau ntxiv los tsim qhov pom kev sib cais.
5. Cov ntsiab lus
Txawm hais tias koj tab tom txhim kho lub tsev nyob tshiab lossis txhim kho kev lag luam hluav taws xob faib hluav taws xob, lubLub nplhaib Main Unit (RMU)-tshwj xeeb yog covBox hom switchgear- muab cov kev daws teeb meem zoo tshaj plaws rau 10kV / 35kV fais fab kev faib tawm. Nws kev sib xyaw ua ke ntawm cov qauv tsim, cov qauv kev nyab xeeb siab, thiab kev txhawb nqa rau lub nplhaib hloov tau yooj yim network teeb tsa ua rau nws tus qauv kev lag luam rau kev txhim khu kev qha theem nrab fais fab.
Tiv tauj peb hnub no kom pom qhov zoo tshaj plaws RMU kev daws teeb meem rau koj qhov project.
