Isingeniso: Yini i-11kV Compact Substation?
11kVisiteshi esincane esihlangeneiyunithi yokusabalalisa amandla eyakhelwe ngaphambili, ezimele ngokwayo eklanyelwe ukuguqula amandla kagesi aphakathi nendawo (ngokuvamile angu-11kV) ukuya ku-voltage ephansi (400V noma 230V) ukuze asetshenziswe umsebenzisi wokugcina.
Izindawo Zokufaka Isicelo
Iziteshi ezingaphansi eziyi-11kV ezihlangene zitshalwe kabanzi kuwo wonke:
- Izindawo zezimboni(izimboni, izigayo zensimbi, imisebenzi yezimayini)
- Ingqalasizinda yezohwebo(izitolo ezinkulu, izikhungo zedatha, izakhiwo zamahhovisi)
- Intuthuko yezindawo zokuhlala(izindlu zasemadolobheni, imiphakathi enesango)
- Izinsiza zomphakathi(iziteshi zikaloliwe, iziteshi zokumpompa amanzi)
- Amasistimu wamandla avuselelekayo(amapulazi omoya, izitshalo ze-solar PV)
Lezi ziteshi ezincane zifaneleka ngokukhethekile iziza lapho isikhala silinganiselwe futhi ukuphepha, isivinini sokufakwa, kanye nokunakekelwa okuphansi kubalulekile.
I-Market Insights namathrendi
Ngokushintsha kwembulunga yonke ekuqondeni kwezinsiza zamandla asabalalisiwe kanye nokufudukela emadolobheni, iziteshi ezincane ezihlangene seziphenduke ingqalasizinda ewumgogodla. IEEMAkanye nemibiko evelaIEEE, isidingo seziteshi ezingaphansi ezingu-11kV sikhule kakhulu ngenxa:
- Ukwenyuka kwamaphrojekthi okuthuthukisa amadolobha
- Igridi ehlakaniphile kanye nezinhlelo zokufaka ugesi ezindaweni zasemakhaya
- Ukuhlanganiswa kwamandla avuselelekayo
Imiklamo yesimanje manje igcizelela i-arc-proof, izakhiwo zensimbi ezihlangene ezinezivikelo ezilinganiselwe nge-IP kanye nezinhlelo ezihambisana ne-SCADA.
Ukucaciswa Kwezobuchwepheshe Nokucushwa
| Ipharamitha | Ukucaciswa |
|---|---|
| I-Voltage elinganiselwe | 11kV |
| Amandla alinganiselwe | 100 kVA – 2500 kVA |
| Uhlobo lwe-Transformer | Ukucwiliswa ngamafutha / Uhlobo olomile |
| Igumbi le-HV | I-SF6 RMU noma i-Vacuum switchgear |
| Igumbi le-LV | I-MCCB/ACB ifakwe ibhodi lokushintsha |
| Uhlobo Lokupholisa | U-ONA / AN |
| Izinga Lokuvikela | IP43–IP55 |
| Uhlobo Lokufaka | Ngaphandle / Kufakwe iphedi |
| Ukuthobela Amazinga | I-IEC 62271, IEC 60076, IS 14786 |
Ukuqhathaniswa Neziteshi Ezingaphansi Ezivamile
| Isici | 11kV Compact Substation | Isiteshi esingaphansi somdabu |
| Unyathela | Encane, ehlanganisiwe | Enkulu, ehlakazekile |
| Isikhathi sokufaka | 1-3 izinsuku | Amasonto kuya ezinyangeni |
| Isondlo | Phansi | Okuphakeme (amasistimu amaningi) |
| Ukuhamba | Ikwazi ukuthutha kalula | Ingqalasizinda engashintshi |
| Ukuphepha | Ivalwe ngokugcwele, i-arc-ephephile | Idinga ukubiyelwa/izithiyo |
Umhlahlandlela Wokukhetha: Ungasikhetha Kanjani Isiteshi Esincane Esiyi-11kV Esilungile
- Hlola Izidingo Zomthwalo: Nquma ukufunwa okuphezulu (ku-kVA/kW).
- Linganisa Imvelo: Ezindaweni ezinomswakama/ezinothuli, khetha izindawo ezivalekile ezilinganiselwe nge-IP54+.
- Uhlobo lwe-Transformer: Uhlobo lukawoyela lokusebenza kahle okuphezulu, uhlobo olomile lokusetshenziswa okuphephile kwangaphakathi.
- Ukunwetshwa okungenzeka: Iziteshi ezincane ze-modular zivumela ukukhuphuka komthwalo wesikhathi esizayo.
- Ukuthobela Umthetho: Qinisekisa ukuthi i-IEC, IS, noma ukulandelwa kwamazinga endawo.
Ukubonisana nabahlinzeki abanolwazi njengoI-ABB,Schneider, nomaSiemensingaqinisekisa ukuthi ukukhetha kwakho kuhambisana nokusebenza nokuphepha okulindelwe.
Imibuzo Evame Ukubuzwa (FAQ)
A: Yebo.
A: Ngokulungiswa okufanele, lawa mayunithi ngokuvamile ahlala iminyaka engama-20-30.
A: Nakanjani.
I-11kVUmhlahlandlela wesiteshi esincaneimele isixazululo sesimanjemanje, esisebenza kahle, nesikakalayo sokusabalalisa amandla kagesi aphakathi nendawo.
