- Khoom Taw qhia
12/0.4kV Prefabricated Secondary Distribution Substation (tseem hu ua kem hom substation 12kV / 0.4kV) yog ua tiav, ua ntej- sib dhos, sab nraum zoov- teeb tsa hluav taws xob faib khoom siv uas hloov 10/12kV nruab nrab-voltage hluav taws xob hluav taws xob rau hauv 0.4kV hluav taws xob thiab hluav taws xob tsawg cov neeg siv kawg. Nws koom ua ke tag nrho cov haujlwm ntawm ib qho chaw ua haujlwm ib txwm ua rau hauv ib lossis ob peb lub thawv thauj khoom hlau.
Core Functions:
1. Voltage Transformation: Cov kauj ruam down voltage ntawm 10/12kV mus rau 0.4kV ntawm lub transformer.
2. Fais fab faib: faib hluav taws xob hluav taws xob rau ntau qhov hluav taws xob hluav taws xob los ntawm qis-voltage switchgear rau kawg- neeg siv.
3. Kev Tiv Thaiv thiab Tswj: Muab kev tshaj tawm, luv -circuit, tiv thaiv lub ntiaj teb txhaum rau lub transformer thiab qis-voltage circuits, thiab ua rau cov chaw taws teeb saib xyuas thiab ntsuas.
4. Fais Fab Kev Kho Kom Zoo: Feem ntau sib koom ua ke qis -voltage reactive fais fab nyiaj them nyiaj pab kiag li lawm los txhim kho daim phiaj efficiency.
Cov Cheebtsam
| Chav tsev | Cov Khoom Siv Core |
|---|---|
| High-Voltage (HV) Chav | 12kV Ring Main Unit (RMU) (SF₆ lossis Nqus insulated) • Chav tsev nkag (nrog thauj khoom- tawg hloov lossis Circuit Court breaker) • Outgoing Unit (rau kev tiv thaiv transformer, feem ntau siv "hloov-fuse" ua ke) • Muaj peev xwm ntsuas qhov ntsuas lossis ntsuas qhov ntsuas siab |
| Transformer Compartment | 12/0.4kV Fais fab Transformer • Peev Xwm: Feem ntau ntawm 315kVA txog 1600kVA. |
| Tsawg-Voltage (LV) Chav | 0.4kV Tsawg-Voltage Switchgear Assembly • LV Main Circuit Breaker (Air Circuit Breaker - ACB) • Ntau lub Feeder Circuit Breakers (Moulded Case Circuit Breakers - MCCB) • Tsis siv neeg Reactive Power Compensation Device (Capacitor Banks) • Intelligent Monitoring/Measurement Units (rau kev tau txais cov ntaub ntawv thiab kev sib txuas lus) |
Qhov Zoo Tshaj Plaws
● Kev ntseeg siab: Lub Hoobkas prefabrication tshem tawm ntawm - qhov chaw ua haujlwm yuam kev; kev ywj pheej compartments tiv thaiv tsis ncaj propagation.
● Hloov kho thiab nthuav dav: High-voltage RMUs thiab qis-voltage switchgear tuaj yeem muab ntxiv lossis txo qhov hloov pauv raws li xav tau, muab kev hloov pauv tau zoo.
● Kev ua haujlwm zoo thiab kev saib xyuas yooj yim: Txhua qhov chaw ua haujlwm muaj lub qhov rooj ywj pheej nrog cov khoom siv meej meej, ua rau kev tshuaj xyuas, kev saib xyuas, thiab hloov khoom siv yooj yim heev.
● Kev sib xyaw ua haujlwm muaj zog: Yooj yim integrates intelligent monitoring systems (SCADA), tej thaj chaw deb kev sib txuas lus (DTU/FTU), ua rau "plaub telemetries" (telemetry, teleindication, telecontrol, thiab teleadjustment). Nws yog ib qho zoo tagnrho rau kev faib network automation.
● Muaj zog Environmental Adaptability: High enclosure tiv thaiv ntsuas (IP40 lossis siab dua), haum rau qhov hnyav sab nraum zoov; cov tsos tuaj yeem ua kom zoo nkauj rau kev sib xyaw nrog cov toj roob hauv pes.
Tej yam kev thov Scenarios
● Kev Tshaj Tawm Hauv Nroog: Lub chaw faib hluav taws xob rau txoj kev, chaw ua si, thiab teeb pom kev zoo.
● Cov Chaw Nyob thiab Chaw Ua Lag Luam: Muab cov chaw ua haujlwm tshwj xeeb rau cov zej zog loj, khw muag khoom, thiab cov tsev ua haujlwm.
● Kev lag luam thiab Infrastructure: Cov ntsiab lus tseem ceeb faib rau cov chaw tsim khoom, tshav dav hlau, chaw nres nkoj, railways, thiab cov chaw khaws ntaub ntawv.
● Tshiab Zog Sector: Daim phiaj kev sib txuas cov ntsiab lus rau cua ua liaj ua teb thiab photovoltaic fais fab chaw nres tsheb.
● Kev siv hluav taws xob ib ntus: Cov khoom siv hluav taws xob ib ntus rau kev tsim kho loj thiab cov chaw ua yeeb yam.
