Ukufakwa okufakiwe, kubuye kubhekiselwenga njengezitho zangasese noma zephakeji, zithuthukile, izixazululo ezihlanganiswe efektri ezihlanganisa i-medium-voltage switchchear, ama-transformers, namaphaneli okusabalalisa amanzi aphansi endaweni ebiyelwe.
Lo mhlahlandlela ugobe imininingwane yezobuchwepheshe, isakhiwo sangaphakathi, amazinga aphesheya, kanye nokusetshenziswa okusebenzayo kweUkufakwa okufakiwe.
Kuyini ukufakwa okuhlangene?
AUkufakwa okuhlangeneIngabe uhlelo olubekiwe, uhlelo olubiyelwe ngokuphelele lwenzelwe ukuguqula nokusabalalisa ugesi kusuka kumandla kagesi aphakathi (e.g., 11kv noma i-33kv) kuya kumandla kagesi aphansi (e.g., 400V).
- Vertage Voltage (MV) Switchchgear: Njengama-ring amayunithi amakhulu (i-RMU) noma i-aver-insud switchgear (AIS).
- Ukusabalalisa i-transformer: Kutholakala ekuhlelweni kwamafutha okucwiliswa uwoyela noma okomile.
- Iphaneli ephansi yeVoltage (LV): Ifakwe ama-MCCBS, ama-MCBS, noma ama-ACB, avame ukufaka metering.
- Into ebiyelayo: Kwenziwe ngensimbi ye-gallvanized, i-aluminium, noma ukhonkolo ukuze kuhlale ukuqina kanye nokumelana nesimo sezulu.
Nga-IEC 62271-202, Ukufakwa kwezinto ezihlangene "kuhlanganiswe efektri, okufakwayo okuhlolwe ngohlobo lwe-transformer okuhloselwe ukusetshenziswa kwangaphandle kumanethiwekhi okusabalalisa komphakathi."
Ukucaciswa okujwayelekile okuhlanganisiwe
Nakhu ukucaciswa okuningiliziwe kweI-1000 kVA 11 / 0.4KVUkufakwa okuhlangene, ukukhetha okujwayelekile kwezicelo zasemadolobheni nezimboni:
| Ukucacisa | Bonisana |
|---|---|
| Amandla alinganiselwe | I-1000 kva |
| Voltage oyinhloko | 11 kv |
| Amandla kagesi wesibili | 0.4 kv |
| Uhlobo lwe-Transformer | I-OIL-EXTERSERED NOMA UTHEMBULO |
| I-MV Switchchgear | I-SF6 Ring main unit noma i-air-incleated |
| Iphaneli ye-LV | ACB / MCCB / MCB nge metering |
| Okufakiwe | Insimbi / I-aluminium / ukhonkolo / ukhonkolo |
| Ileveli yokuvikela | IP54 (Outdoor) |
| Indlela yokupholisa | I-Onan (oyela wemvelo yomoya wemvelo) / anaf |
| Ukuhambisana okujwayelekile | I-IEC 62271, IEC 60076, IEEE STD C57 |
Qaphela: Ukucaciswa kungalinganiswa ngezidingo zephrojekthi.
Ukwakheka kwangaphakathi kokufakwa esikhundleni esihlangene
Ukwakheka kwe-hlangene endaweni encaneukubusisaIzobunjiniyela ukuphepha, ukufinyeleleka, nokusebenza kahle.
- Igumbi le-MV: Izindlu SF6 noma i-air-infated switchgear ukuphatha okokufaka kwamandla aphakathi nendawo.
- Igumbi le-transformer: Kuqukethe i-transformer enezici zokuphepha ezifana nezinzwa zokushisa nezinhlelo ezihlabayo.
- Ikomela: Kubandakanya ama-breakers wesifunda, amamitha, kanye namaphaneli okulawula okukhipha amandla aphansi.
Lezi zinhlaka zihlukaniswe yizithiyo zomlilo futhi zifakwe umoya omncane, izinhlelo zokucindezela kwe-arc, kanye nemisele yentambo ukuthuthukisa ukuphepha nokunakekelwa kokuphepha.
Izimiso Zomhlaba Wonke Nemigomo Yokuklama
Ukufakwa kokutholwa okuhlangene kumele kuhambisane namazinga aqinile omhlaba ukuqinisekisa ukusebenza nokuphepha.
- IEC 62271-202: Ibusa ukwakheka kanye nokuhlolwa kwezingane ezihlanganiswe ne-HV / LV.
- IEC 60076: Icacisa izidingo zamandla we-transformers.
- IEEE C37.20: Imininingwane emazingeni okushintshana kwensimbi-clad.
- Ukucaciswa kwe-TNB (iMalaysia): Uchaza ukwakheka kwamanethiwekhi okusetshenziswa kweMalaysian.
- I-SANS 1029 (South Africa): Ukulawula ukwakheka okufakiwe okufakiwe.
Ngokuvumelana neIEC 62271-202, Izakhi ezihlolwe kakhulu, kufaka phakathi amandla e-dielectric, ukukhuphuka kwezinga lokushisa, ukumelana kwesizungu, nokuhlola okuvalekile.
"Ukufakwa kwezinto ezihlangene kuguqula ukusatshalaliswa kwamandla okusebenza kwamandla aphakathi nokusebenza kwazo kanye nokuvumelana nezimo," kuphawula i-2021 Iee Power & Energy Society Paper (umthombo).
Izicelo zokufakwa kwezinto ezihlangene
Ukufakwa okufakiweI-Excel kwizimo ezidinga ukusebenza kahle kwendawo kanye nokwethenjwa:
- Izindawo zasemadolobheni: Izakhiwo zezentengiselwano, izakhiwo zokuhlala.
- Ukuthutha: Izikhungo zezindiza, iziteshi zikamasipala.
- Ubuchwepheshe: Izikhungo zedatha.
- Imboni: Amafektri, amasayithi wezimayini.
- -Ngavuselelwa: Amapulazi elanga namanzi.
- Amaphrojekthi Wasemakhaya: Izinhlelo zokufakelwa kagesi.
- Izinto ezibalwayo: Ukusatshalaliswa kwamandla kahulumeni.
Idizayini yabo evalekile, eqinile futhi ifanela izimo ezedlulele njengezindawo zogwadule, izifunda ezisogwini, noma ezikhuphukayo ezibandayo.
Izinzuzo ezibalulekile zokufakwa kwezinto ezihlangene
- Ukusindisa isikhala: Yehlisa i-FootPrint ngo-50% uma kuqhathaniswa nezingane zendabuko.
- Ukuthunyelwa okusheshayo: Kuhlanganiswe kwangaphambili ukufakwa kwe-plug-and-play.
- Ukuphepha: Izici ezivalekile zokuthinta ubufakazi kanye nokuvikelwa kwamaphutha a-arc.
- Ukulungiswa okuphansi: Idizayini eguqukayo yenza lula ukulungiswa nokuthuthuka.
- Izici ze-Smart: Ukuhlanganiswa kwe-IOT noma ukuhlanganiswa kwe-scada kokuqapha kwangempela.
Isibonelo sangempela somhlaba: Ukufakwa kwesihlanganisiwe ku-Action
Ngo-2022, aI-1500 kva ecwengekileyafakwa kuphrojekthi ephezulu yezentengiselwano ye-Dubai. IEC 62271, lilingana nomthungo endaweni engaphansi.
"TheI-Compact GuideImvelo yangaphambi kokuqoqeka yasigcina isikhathi esibalulekile kanye nezinsizakusebenza, "waphawula unjiniyela wokuhola wephrojekthi.
Imibuzo ebuzwa njalo (i-FAQ)
A: Ngokulondolozwa njalo - njengokuhlola uwoyela we-transformer kanye nokuhlolwa kwe-switchchear - bangasebenza ngokuthembekile iminyaka engaphezu kwengu-25.
A: Abaguquli abagcwele uwoyela babiza kakhulu futhi basebenza kahle, kanti amayunithi wohlobo omile anikeza ukuphepha komlilo okuphezulu, elungele izilungiselelo zangaphakathi.
A: Yebo.
-Hlangene endaweni encaneI-KVA Compact Substation InhlosoThumela ikhambi eliguquguqukayo, elisebenzayo lokusatshalaliswa kwamandla kwanamuhla. IEC 62271na-IEEE C37.20, kubhangqiwe ngokusebenza okufakazelwe kuyo yonke imboni, kubenza babe ukukhetha okuphezulu konjiniyela emhlabeni jikelele.
Lapho ukhetha ukufakwa okuhlangene, qinisekisa ukuthobela kwezobuchwepheshe, ukulingana kwezemvelo, nobuchwepheshe bomhlinzeki.
