I-transformer yamandla ka-66kV egxilwe emafutheni iyisishintshi samandla esinezinga lamandla angu-66kV, esisebenzisa uwoyela wokuvikela njengendlela eyinhloko yokuvikela nokupholisa. Isetshenziswa kakhulu ekudluliseleni amandla, ekusabalaliseni nasekushintsheni kwamandla ezingxenyeni zamandla zesifunda, eziteshini zamandla kanye nezinkampani ezinkulu zezimboni nezimayini.

I. Isakhiwo Senhliziyo
1. Umzimba (Core)
I-Core: Yenziwe ngama-sheetenshini ensimbi ye-silicon ebandayo egudluzelwe okusanhlamvu, enezixhumanisi ezigcwele ezingenawo izimbobo zokubopha, eyakha umjikelezo wamandla ovaliwe.
Ama-windings: Ama-windings aphezulu naphansi (izinto zobhedu/zethusi) agxunyekwe ngokuhambisana ezinsaleni zenhliziyo, anephepha lokuvikela / ikhadibhodi phakathi kwezendlalelo ukuqinisekisa amandla kagesi.
Ukuvikeleka: Izintambo zigcinwa ngokuthembekile kude ne-core kanye nomunye nomunye nge-oyili yokuvikela nezingxenye eziqinile zokuvikela (amathiphu ephepha, izinduku zokusekela).
2. Ithangi likawoyela kanye ne-Cooling System
I-Tank ye-Oyili: Umkhono wensimbi, holding insulating oil, ivikela umzimba futhi ibamba iqhaza ekuphumeleleni kokushisa.
I-Cooling Device:
Ukuphuma Kwenziwa Ngomoya (ONAN): Ukuncika ekuphakamiseni kwe-oyili ukuze kupholise i-oyili edlula odongeni be-tank ye-oyili / i-heat exchanger.
I-Forced Oil Circulation (OFAF/ODAF): Inama-oil pump nama-fan ukuze kuthuthukiswe amandla okupholisa.
3. Izinsiza Eziyinhloko

I-Oil Sump: Ilungisa ivolumu kawoyela, ihlukanisa umoya, futhi yehlisa ukuguga kukawoyela.
I-Breather: Idonsa umswakama emoyeni.
I-Tap Switch: Ukulawulwa kwamandla kagesi ngaphandle kokuthatha umthwalo (±5% noma ±2×2.5%) noma ukulawulwa kwamandla kagesi ngesikhathi kuthathwa umthwalo (nokulungiswa kwamandla kagesi ngomthwalo).
Izinsiza Zokuvikela: I-gas relay (ukuvikela okungaphakathi), i-valve yokukhulula ingcindezi, i-thermometer, i-oil level gauge.
I-Bushing: Imikhondo yamandla aphezulu naphansi kagesi iyakhishwa ethangini likawoyela ukuze kufezekiswe ukuvikelwa komhlaba.

II. Umqondo Wokusebenza
Kususelwa kumthetho wokufakwa kukagesi okuzenzakalelayo:
66kV alternating current isetshenziswa ohlangothini lwe-high-voltage → i-magnetic flux eguquguqukayo ikhiqizwa kwi-core.
I-magnetic flux idlula ku-low-voltage winding → amandla kagesi ahlukene (U₁/U₂ = N₁/N₂) ayenziwa.
I-oyili yokuvikela iphinde ikwenze kokubili ukuvikela nokuhambisa ukushisa ngesikhathi esifanayo.

III. Imidwebo kanye Nezici (Ezivamile)
Imodeli Ejwayelekile: S11/S13-6300/66, SFZ11-31500/66
S: Amagxathu amathathu; F: Ukupholisa ngomoya; Z: Ukulawulwa kwamandla kagesi okungalayishi; 11/13: Ukulandelana kokusebenza; 6300: Umthamo (kVA); 66: Uhlangothi lwamandla aphezulu kagesi (kV).
Ibanga le-Voltage: 630 kVA ~ 63,000 kVA (Evamile: 6300 ~ 40,000 kVA).
Ukuhlanganiswa kwamavoltage:
Amandla Aphezulu: 66 ± 2 × 2.5% kV
I-Voltage Ephansi: 6.3 kV / 6.6 kV / 10.5 kV / 11 kV
Inombolo Yeqembu Lokuxhuma: YNd11 (Inkanyezi yamandla aphezulu, i-delta yamandla aphansi, umehluko wezigaba ezingu-11).
Ukumelana nesekethe elifushane: 9% ~ 12% (Kuya ngamandla).

IV. Izici Zokusebenza
Izinzuzo
Ukuvikelwa okuhle kakhulu nokuhlakazeka kokushisa: Imidiya kawoyela inokusebenza okuzinzile namandla amakhulu okubekezelela ukulayisha ngokweqile.
Ubuchwepheshe obuphumelelayo, ukwethembeka okuphezulu, impilo ende (ukuze kube seminyakeni engu-20-30).
Izindleko eziphansi, isipiliyoni esicebile sokugcinwa.
Ukumelana okuhle kakhulu nokushintshashintsha, kufaneleka ezindaweni zangaphandle ezinzima.
V. Izimo Zokusebenza
Iziteshi zamandla zesifunda ezingama-66kV (ukwehlisa ukuya kunethiwekhi yokusabalalisa eyi-10kV).
Ama-transformer amakhulu noma ama-transformer okuxhumanisa ezitshalweni zamandla ezinkulu / eziteshini zamandla.
Imithwalo yamandla enomthamo omkhulu, nokwethembeka okuphezulu emikhakheni efana ne-metallurgy, i-petrochemicals, kanye nezimayini.
VI. Izindinganiso Zokusebenza
GB 1094: "Amandla Transformers"
GB/T 6451: "Technical Parameters and Requirements for Three-Phase Oil-Immersed Power Transformers"

VII. Amaphuzu Abalulekile Okukhetha
1. Khetha amandla akaliwe ngokomthwalo (shiya u-15-20% wemajini).
2. Nquma imodi yokulawula amandla: ayikho i-excitation (amandla azinzile) noma i-on-load (ukushintshashintsha kwamandla kukhulu).
3. Khetha indlela yokupholisa (ONAN/OFAF) nezinga lokuvikela ngokwendawo.
4. Phambili izinhlobo ezine-loss ephansi (S11/S13/S15) ukunciphisa izindleko zokusebenza.
