.I-11/33 I-KV ExtentationIdlala indima ebaluleke kakhulu kumanethiwekhi okusatshalaliswa kwamandla aphakathi kwamandla.
Ukuqonda ukwakhiwa kanye nokusebenza kwe-11/33 kVUkubusisaibalulekile ku-Power Onjiniyela, abathuthukisi, kanye nabahleli bamandla.
1. Kuyini indawo engu-11/133 kV?
.I-11/33 I-KV ExtentationYenzelwe ukwehla kwamandla kagesi kusuka ku-33kV kuya ku-33kv kuya ku-11kv noma uphakame kusuka ku-11KV kuya ku-33kV kuya ku-33kv, kuya ngesendlalelo senethiwekhi.
Amacala ajwayelekile okusetshenziswa:
- Ukwehla kwe-voltage ngaphambi kokuthi kungenise izindawo zezimboni noma zezentengiso.
- Ukuhlangana phakathi kwamanethiwekhi okusatshalaliswa kwamabanga aphansi nawesibili.
- Ukusebenza njengamaphoyinti wokujova kwegridi ezitshalweni zamandla avuselelekayo.
2. Izakhi ze-11/33 KV
Okulungiselelweukubusisawalesi sigaba ngokuvamile kufaka phakathi:
a.
Abaguquli yinhliziyo yokufakwa esikhundleni, ukuguqula amazinga we-voltage ngokusebenza okuphezulu.
b.
Kubandakanya:
- Abaphula umjikelezo(Vacuum noma i-SF6)
- Ukunqamula / ama-isolators
- Ukulayisha ukushintshwa kwekhefu (lbs)
- Ukushintshwa komhlaba
c.
Lokhu kubaqhubi be-Copper / Aluminium abasetshenziselwa ukusabalalisa amandla.
d.
Ukufakwa kwezinto kwanamuhla kuhlanganiswe ne-IEDS (amadivaysi e-elekthronikhi ahlakaniphile) ahambisanaIEC 61850.
- -Gqamile
- Ukwahlukanisa
- Ukuvikelwa Kwebanga
e.
Vimbela izimbotshana ze-transvoltages ezintweni ezilimazayo.
f.
Amabhange ebhethri, amashaja webhethri, nezinhlelo zokukhanyisa.
3. Ithebula lezobuchwepheshe
| Parametr | Uhla olujwayelekile |
|---|---|
| Voltage oyinhloko | 33 kv |
| Amandla kagesi wesibili | 11 kv |
| I-Frekxence | 50 Hz |
| Isilinganiso sokuguqula | I-500 kva kuya ku-10 mva |
| Ileveli yesekethe elifushane | 25-31.5 ka nge-3 sec |
| Uhlobo lwe-Breaker | I-VCB / SF6 |
| Ukuxhumana kabusha | IEC 61850, Modbus, DNP3 |
| Ukuphikiswa Kokulwa | <1 ohm (okujwayelekile) |
| Ukuhlanganiswa kokufaka | BIL 170 KVP |
4. Ukucatshangelwa Kwemiklamo Yokubuyiselwa
Ukuqamba indawo ephezulu yokusebenza kufaka izingqimba eziningana:
a.
Bala imithwalo ye-Peak ku-Usayizi Orfapy ngendlela efanele.
b.
Qinisekisa ukudluliselwa kanye nabaqhekezi basebenza ngokukhetha ukuhlukanisa isigaba esinephutha kuphela.
c.
Nquma ukuthi uzosebenzisa yini-ngaphandlenomai-switchgear yangaphakathi, I-GIS (igesi efakwe igesi), noma i-AIS (AIR efakiwe).
d.
Faka phakathi ukuqina kokuzamazama komhlaba, umoya, nokulinganisa kokulinganisa kokuqina.
e.
Ukuvunyelwa okwanele nokuphepha kokuphepha kubalulekile.

I-5. Izicelo ze-11/33 KV
- Amapaki Wezimboni
- Izindawo ezinkulu zezentengiso
- Amapulazi elanga kanye nomoya
- Ukufakwa kukahulumeni
- Ama-grid kagesi asemadolobheni nase-peri-Urban
Lokhu kufakazelwa kuvame ukusetshenziselwa ukondla ama-11kv Ring Main Units (Rmus) ezindaweni eziminyene.
6. Ukuhambisana namazinga wamazwe aphesheya
-Nkeukubusisakumele uvumelane ne:
- IEC 62271-100 / 200 (i-high-voltage switchchear)
- Ngu-1180 (ama-transformers okusabalalisa)
- IEEE 1584 (Ukuhlaziywa kwe-ARC Flash)
- I-ISO 45001 (ukuphepha emsebenzini)
7. Ukufakwa kokufakwa kwezinyathelo & izinyathelo zokuthumela
a.
Ucwaningo, ukumbiwa, kanye nezisekelo zokhonkolo.
b.
Ukubekwa kwama-transformers, amaphaneli, ama-breakers, kanye nama-ducts webhasi.
c.
Ukuqinisekisa ukuhlolwa okufanelekile kanye nokuhlolwa kwentambo.
d.
Ukuhlolwa kwenani le-IR, umjovo wamabanga aphansi / wesibili, izilungiselelo ezidluliselwe.
e.
Ukuqalisa okuhleliwe ngokuqapha ama-SOLTAGE SAGS / ukuvuvukala.
8. Izinzuzo zokufakwa kwezingane eziyi-11 / 33kv
- Ukuthunyelwa kwe-voltage okuthuthukile
- Ukuphathwa kahle komthwalo
- Ukuhanjiswa okuguquguqukayo nokweguquguquka
- Izinga eliphakeme lokuphepha kokusebenza
