Ntiv Nplhaib Ntsiab Cai Ua Haujlwm
Nplhaib Network Topology
Lub nplhaib tseem ceeb ua haujlwm nyob rau hauv lub kaw - lub voj kev faib tawm uas lub zog tuaj yeem ntws los ntawm ob txoj kev. Lub network yog lub nplhaib ntawm lub cev - txuas tab sis ib txwm ua haujlwm nrog ib qho chaw qhib los tiv thaiv kev ua haujlwm sib luag thiab ua kom yooj yim rau kev sib koom tes tiv thaiv.
Kev ua haujlwm li qub
Raws li ib txwm muaj, RMU faib hluav taws xob los ntawm kev hloov pauv hloov pauv thiab cov hluav taws xob hluav taws xob. Ib qho kev hloov pauv hauv lub nplhaib tseem qhib (ib txwm qhib taw tes), tiv thaiv cov dej ntws tawm thaum tswj kev rov ua dua rau kev hloov pauv sai.
01
Fault Detection & Isolation
Thaum muaj teeb meem tshwm sim (luv luv Circuit Court, overload, los yog hauv av txhaum), kev tiv thaiv relays pom qhov txawv txav tam sim no thiab ua rau lub Circuit Court breaker los yog fuse mus txawv tebchaws. Lub RMU cais tsuas yog cov faulty cable seem thaum ua kom tus so ntawm lub network energized.
02
Kev muab khoom rov qab
Tom qab kev sib cais tsis raug, qhov ib txwm qhib qhov chaw kaw kom rov qab muaj zog rau cov seem noj qab haus huv los ntawm lwm qhov chaw. Hauv automated RMUs nrog DTU/SCADA kev koom ua ke, cov txheej txheem no ua tiav hauv vib nas this - txo qis qis.
03
Kho & Rov qab mus rau qhov qub
Thaum kho qhov txhaum, cov neeg ua haujlwm tuaj yeem ua haujlwm ruaj ntseg siv lub ntiaj teb hloov pauv, tom qab ntawd rov qab qhib lub network rau nws qhov qub qhib - taw tes teeb tsa. Lub kaw lus rov qab mus rau tus qauv ua haujlwm nrog kev rov ua dua tshiab.
04
Core Cheebtsam ntawm Nplhaib Cov Ntsiab Cai
Peb -Txoj haujlwm Load Break Hloov (LBS)
Lub plawv ntawm RMU - sib txuas cov kev pabcuam, kev sib cais, thiab kev ua haujlwm hauv av hauv ib qho kev sib cog lus. Ua kom muaj kev nyab xeeb thauj khoom hloov pauv, pom kev cais tawm, thiab ruaj ntseg hauv av rau kev saib xyuas.

Muab kev tiv thaiv txhaum rau downstream transformers thiab feeders. Tsis siv neeg cuam tshuam luv luv Circuit Court thiab overloads los tiv thaiv cov khoom puas thiab txwv tsis pub tshaj tawm.
Earthing Hloov
Qhov tseem ceeb ntawm kev ruaj ntseg tivthaiv uas ua rau cov khoom siv hluav taws xob thaum lub sij hawm tu, xyuas kom tsis muaj hluav taws xob seem thiab tiv thaiv cov neeg ua hauj lwm los ntawm hluav taws xob hluav taws xob thaum lub sij hawm tshuaj xyuas thiab kho ua hauj lwm.
Busbar System
High -conductivity tooj liab lossis txhuas busbars faib fais fab hauv nruab nrab ntawm cov hloov pauv. Engineered rau qhov zoo tshaj plaws tam sim no nqa peev xwm thiab tsawg kawg kub nce.
Tam sim no thiab Voltage Transformers
CTs thiab PTs / VTs muab qhov ntsuas thiab ntsuas qhov tseeb rau kev tiv thaiv relays, ntsuas, thiab saib xyuas cov haujlwm. Muaj nyob rau hauv ntau cov chav kawm raug rau cov kev siv sib txawv.
Kev Tiv Thaiv thiab Tswj Relay
Cov khoom siv hluav taws xob ntse (IEDs) muab cov khoom siv hluav taws xob ntau dhau, kev ua txhaum hauv ntiaj teb, thiab kev tiv thaiv transformer. Txhawb kev sib txuas lus raws tu qauv rau SCADA kev koom ua ke thiab feeder automation.
Interlock System
Cov khoom siv hluav taws xob thiab hluav taws xob cuam tshuam tiv thaiv kev ua haujlwm txaus ntshai xws li earthing nyob rau hauv load lossis kaw rau hauv ib qho chaw hauv av. Ua kom tus neeg teb xov tooj muaj kev nyab xeeb txhua lub sijhawm.
DTU / RTU Module (Yeem)
Distribution Terminal Unit ua rau kev saib xyuas tej thaj chaw deb, tswj, thiab automation. Txhawb kev qhia yuam kev, hloov chaw taws teeb, thiab kev sib txuas lus nrog SCADA / DMS systems rau kev ua haujlwm ntawm daim phiaj ntse.

FAQ
Lub Nplhaib Main Unit lub luag haujlwm tseem ceeb hauv kev faib hluav taws xob yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm Ring Main Unit (RMU) yog hloov, tiv thaiv, thiab cais nruab nrab-voltage feeders nyob rau hauv lub nplhaib- hom kev faib tawm. Nws ua rau lub zog bidirectional ntws kom thaum muaj kev txhaum tshwm sim ntawm ib ntu, lub zog tuaj yeem hloov pauv los ntawm kev hloov pauv, txo qis qis qis thiab ua kom cov khoom txuas ntxiv mus rau cov neeg siv khoom feem ntau.
Cov chav kawm voltage dab tsi muaj rau Ring Main Units?
Ring Main Units muaj nyob rau hauv ntau chav kawm voltage kom haum raws li qhov sib txawv network. Feem ntau yog 12kV (feem ntau hu ua 10kV hauv kev tsim vaj tsev niaj hnub). 24kV RMUs muaj nyob rau hauv kev lag luam txawv teb chaws thiab kev lag luam kev lag luam. 33kV thiab 36kV RMUs tau siv dav hauv kev faib hluav taws xob, kev siv hluav taws xob txuas dua tshiab, thiab chaw ua si. Peb cov khoom lag luam RMU npog 12kV, 24kV, thiab 36kV chav kawm.
Dab tsi yog qhov txawv ntawm GIS RMU thiab AIS RMU?
GIS (Gas-Insulated Switchgear) RMUs siv SF6 roj los yog eco- cov kev hloov hauv tus phooj ywg raws li qhov nruab nrab insulating, muab cov hneev me me, kev ntseeg siab dua, thiab kev tiv thaiv ib puag ncig zoo dua. Lawv zoo tagnrho rau hauv nroog thiab chaw- txwv kev teeb tsa. AIS (Air-Insulated Switchgear) RMUs siv huab cua ua rwb thaiv tsev, qis dua tus nqi thiab yooj yim los tswj, tab sis xav tau ntau qhov chaw thiab feem ntau siv hauv tsev hauv qhov chaw huv si. Khoom-insulated RMUs yog ib qho kev xaiv thib peb uas sib xyaw ua ke nrog xoom tsev cog khoom roj cuam tshuam.
Muaj pes tsawg feeders tuaj yeem txhawb nqa lub Nplhaib Main Unit?
RMUs yog configurable heev. Ib tus qauv 3-txoj kev (2+1) RMU muaj ob lub nplhaib feeder keyboards ntxiv rau ib qho kev tiv thaiv transformer - feem ntau configuration rau compact substations. Muaj ntau txoj kev teeb tsa nrog 4, 5, lossis ntau lub vaj huam sib luag muaj rau cov khoom faib loj dua. Tus naj npawb ntawm cov feeders nyob ntawm koj lub network topology thiab cov kev cai thauj khoom. Peb cov engineers tuaj yeem pab koj txiav txim siab qhov zoo tshaj plaws configuration rau koj qhov project.
Ring Main Units puas tuaj yeem koom ua ke nrog cov phiaj xwm ntse?
Yog lawm, niaj hnub Nplhaib Cov Ntsiab Lus tseem ceeb tag nrho - daim phiaj npaj. Thaum nruab nrog DTU (Distribution Terminal Unit) lossis RTU (Remote Terminal Unit) modules, RMUs txhawb kev saib xyuas tej thaj chaw deb, kuaj xyuas qhov txhaum, tsis siv neeg cais, thiab tus kheej - kho lub network ua haujlwm. Lawv sib txuas lus nrog SCADA/DMS systems los ntawm cov txheej txheem kev cai, ua kom muaj tiag -lub sij hawm network tswj thiab kwv yees saib xyuas rau niaj hnub ntse tis daim phiaj.
