01 Kakaretso

1.1 Tlhaloso ea Morero

1000 kVA phase three phase mounted transformer e ile ea isoa USA ka 2026. Matla a lekantsoeng a transformer ke 1000 kVA e nang le pholiso ea KNAN. Matla a phahameng ke 24GrdY/13.8 kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase o tlase ke 0.416Y / 0.24 * 0.24D kV, ba thehile lihlopha tse peli tsa li-vector tsa YNyn0 / YNd11.

Litlhophiso tsa Dual Low-Voltage Vector Group bakeng sa Phetoho ea Voltage

Karolo e ikhethang ea projeke ena ke tlhophiso ea sehlopha sa li-voltage tse tlase tsa transformer, e hlophisitsoeng joalo ka YNyn0/YNd11. Khokahanong ea YNyn0, maqhubu a phahameng a motlakase le a tlase ke naleli e hokahaneng le lintlha tse sa nke lehlakore tse hlahisitsoeng, 'me lehlakore la motlakase o tlase le lula le le mothating le lehlakoreng le phahameng la motlakase. Tokisong ea YNd11, moea oa motlakase o tlase o hokahantsoe le delta, e leng se bakang lebelo la 30℃phase lead (kapa 330℃lag) le amanang le lehlakore le phahameng la voltage. Moralo ona oa lihlopha tse peli tsa li-vector o thusa phetoho e bonolo lipakeng tsa litlhophiso tse fapaneng tsa motlakase o tlase, e lumellang moreki ho ikamahanya le litšobotsi tsa motlakase oa motlakase oa motlakase ho fihlela litlhoko tse fapaneng tsa sistimi. Ka likhokahano tsa ka hare tse ka lokisoang bocha le ts'ebeliso ea ntlha e sa nke lehlakore, transformer ha e khone ho fana feela ka maemo a tloaelehileng a 0.416 kV (mohala ho ea ho mola) le 0.24 kV (mohala ho ea ho lehlakore / delta), empa hape le pompo ea 0.12 kV e tlase ea voltage, e fanang ka khetho ea boraro bakeng sa mejaro e khethehileng kapa litlhoko tsa phepelo e thusang. Ts'ebetso ena e matlafalitsoeng e etsa hore li-transformer tsena li tšoanelehe haholo bakeng sa maemo a fapaneng a likhokahano tsa gridi le lits'ebetso tsa motlakase tse ngata.

Tlhokahalo ea Tlhahlobo ea Mofuta: Tekanyo ea Khahlano ea DC Winding

Ka ntle ho liteko tse tloaelehileng tse boletsoeng ho protocol ea tekheniki, morero ona o na le tlhokahalo e khethehileng: tekanyo ea DC Winding Resistance e khethiloe e le teko ea mofuta o tlamang. Teko ena e kenyelletsa ho kenya motlakase o laoloang oa DC ka har'a moea o mong le o mong oa transformer le ho lekanya ho theoha ha motlakase ho bala litekanyetso tsa ho hanyetsa. Teko ea ho hanyetsa mapheo a DC ke sesebelisoa sa bohlokoa sa tlhahlobo se sebelisetsoang ho tseba ho khaotsa ho sebetsa, likhokahano tse fokolang, le li-circuits tse bulehileng ka har'a mapheo, hammoho le ho netefatsa botšepehi ba likhokahano tsohle tsa lipompo. Ka ho etsa teko ena e le teko ea mofuta ho e-na le ho etsa tlhahlobo e tloaelehileng, moreki o fumana kholiseho e phahameng mabapi le ho tsoela pele, boleng ba khokahanyo, le ho nepahala ka kakaretso ho etsoa ha li-transformer tsena{3}e leng tlhokomeliso ea bohlokoa haholo ha ho nahanoa ka-moetso oa lihlopha{5} tsa li-vector{5}le tlhokeho ea ts'ebetso e tšepahalang tlas'a tlhophiso ea likhokahano ka bobeli.

03 Teko

Liteko tsohle li etsoa ho latela IEEE C57.12.34 2022 le IEEE C57.12.90.
Liteko tsa ka mehla (tse etsoang yuniting e 'ngoe le e 'ngoe):
• Fetosa karo-karolelano le phalliso ea mokhahlelo (YNyn0 le YNd11 li netefalitsoe)
• Ha ho tahlehelo ea mojaro le hona joale e thabisang
• Ho lahleheloa ke moroalo le motlakase oa impedance
• Matla a mahlahahlaha a sebelisitsoeng (HV: 40 kV; LV: 10 kV)
• Matla a matla a ho mamella
• Teko ea ho lutla ha tanka (50 kPa bakeng sa lihora tse 12)
• Matla a dielectric a oli ( A maholo ho feta kapa a lekana le 45 kV)
• DC insulation resistance and polarization index
Liteko tsa mofuta - tlhokahalo e khethehileng bakeng sa morero ona ke hore tekanyo ea DC Winding Resistance e khethiloe e le teko ea mofuta o tlamang, eseng feela tlhahlobo e tloaelehileng. Teko ena e kenya motlakase oa DC o laoloang sebakeng se seng le se seng 'me e lekanya ho theoha ha motlakase ho bala litekanyetso tsa ho hanyetsa. Ke tlhahlobo ea bohlokoa bakeng sa ho bona likhoele tse robehileng, likhokahano tse fokolang tsa interturn, kapa li-joints tsa theipi tse hlephileng. Ka ho e etsa e le tlhahlobo ea mofuta, re fana ka boemo bo phahameng ba tiisetso mabapi le ho tsoela pele le botšepehi ba khokahano - ho bohlokoa haholo ho latela litlhophiso tse peli tse fapaneng tsa lihlopha tsa vector.

Ho tsoa tlalehong e phethiloeng ea teko (Seriale No{0}}), litekanyetso tse lekantsoeng:
• Ha ho tahlehelo ea mojaro: 1.1445 kW
• Ho lahleheloa ke mojaro (85℃): 12.037 kW
• Tšitiso: 5.74%
• Ho sebetsa hantle: 99.23% - kaofela ho feta lipalo tse tiisitsoeng.

 

 

04 Matšoenyeho a Bareki

Lintlha tse 'maloa tsa bohlokoa li rarollotsoe ho fihlela litlhoko tse ikhethileng tsa moreki oa Canada:

• Ts'ebetso ea sehlopha sa li-vector tse peli (YNyn0/YNd11): Lihokelo tsa ka hare li entsoe e le hore matsoelintsoeke a LV a ka hlophisoa bocha ho tloha naleling ho ea ho leriba. Ho naleli, mohato oa ho se nke lehlakore ke 240 V le mola ho ea ho 416 V; karolong ea delta, khoele ea ho ea mola e sala e le 416 V, ha theipi e bohareng e fana ka 120 0 120 V (ke hore, 0.12 kV) bakeng sa mejaro e thusang. Phetoho e bonolo, e sebelisa lipoleiti tse fanoeng.
• Tlhokahalo ea tlhahlobo ea mofuta: Moreki o ile a kopa DC winding resistance e le teko ea mofuta - sena se ba fa bopaki bo ngotsoeng ba ho lumellana ha tlhahiso le boleng ba khokahanyo ho pholletsa le litlhophiso tse peli tse matsoelintsoeke.
• Tikoloho ea lebopo la tropike: Li-transformer li entsoe ka ts'ireletso e matlafalitsoeng ea kutu (sistimi ea pente e teteaneng, hardware ea tšepe e sa hloekang) le maemo a phahameng a BIL ho mamella ho otla ha lehalima khafetsa, mongobo o phahameng, le moea oa letsoai, ho latela litlhaloso tsa Jamaican (JPSCo 6950 S 04).
