Ubuchwepheshe Obuyinhloko Beziguquli Zokudonsa Izitimela Zesitimela: "Inhliziyo Enamandla" Eqhuba Izitimela Zesikhathi Esizayo

Imakethe yomhlaba wonke ye-traction transformer izodlula amaRandi ayizigidi eziyi-12 ngo-2025, lapho iShayina inikela ngaphezulu kwama-40% njengoba ubuchwepheshe bushintsha imboni

Ama-transformer okudonsa isitimela asebenza njengemishini eyinhloko yezinhlelo zamandla okudonsa, enza imisebenzi emithathu ebalulekile:ukuguqulwa kwamandla, ukulawulwa kwamandla kagesi, kanye nokuvikelwa kokuhlukaniswaLesi sihloko sihlaziya indlela ezivumela ngayo ukusebenza kahle kwezinhlelo zesitimela esinejubane eliphezulu, izitimela ezingaphansi komhlaba, kanye ne-maglev ngokusebenzisa izimiso zobuchwepheshe, izinto ezintsha, kanye nezinhlelo zokusebenza.

 

 

I. Ukuziphendukela Kwemvelo: Kusukela Ekuphindaphindeni Komugqa kuya Kuma-Transformer E-elekthronikhi Anamandla

1. Ukulinganiselwa Kwabaguquli Bendabuko

 

Usayizi omkhulu: Ihlala ngaphezu kuka-30% wendawo yenqola engaphansi kwenqola, okunciphisa umthamo/isivinini sabagibeli

 

Uphahla olusebenza kahle: Ukulahlekelwa amandla okungu-5-8%, okubi kakhulu ngesivinini esiphansi

 

Umsebenzi owodwa: Ayikwazi ukubuyisa amandla okuvuselela amabhuleki

 

2. Ukuphumelela kuma-Power Electronic Transformers (PET)

I-CRRC Zhuzhou Institute ithuthukise i-I-PET yokuqala engu-25kV emhlabeni ngo-2023, ukufeza:

 

Ukunciphisa isisindo: 20% encane, 15% ilula (umthamo ofanayo)

 

Ukusebenza kahle okuphezulu: Ukusebenza kahle okungu-98.5%, ukulahlekelwa okungaphansi ngo-40% ngaphandle komthwalo

 

Ukulawula okuhlakaniphile: Amamojula e-IGBT (6.5kV/2kHz) avumela ukulungiswa kwamandla ngesikhathi sangempela

 

II. Izinhlobo Eziyinhloko Nokuqhathanisa Kobuchwepheshe

III. Ubuchwepheshe Obusezingeni Eliphezulu Obushintsha Ushintsho

1. Ukuguquka Okukhulu Kwemvamisa Nokwezinto Ezibonakalayo

 

Ama-cores anombala ohlukile: Ukulahlekelwa okungadingi mthwalo okuphansi ngo-70% (iphrojekthi ye-Jinpan Tech metro)

 

Amadivayisi e-SiC/GaN: Imvamisa yokushintsha engu-10kHz, ukupholisa okungaphansi ngo-30%

 

I-epoxy eguquliwe kancane: Ukumelana nokuqhekeka okuphezulu okungu-50%, isikhathi sokuphila samahora angu-400k

 

2. Izinhlelo ze-Smart O&M

 

I-DGA eku-inthanethi: >95% ukunemba kokubikezela amaphutha

 

Amawele edijithali: I-Siemens TrafoStar™ yehlisa izindleko ze-O&M ngo-40%

 

3. Ukuvuselela Amandla Okuvuselela

 

Ama-transformer empendulo: Buyisela amandla okubhuleka kugridi (I-Shanghai Metro Line 3 isindisa u-15%)

 

Ukudonsa okuphuthumayo: 110V → 1200V boost converters zokubuyisa ukwehluleka (uhlelo lukaGuangyi Electric olunamandla angu-53kW)

 

IV. Izixazululo Ezisekelwe Ezimweni

1. Ukudonsa Isitimela Esisheshayo

 

Isidingo: Ukuqina ku->300km/h

 

Isixazululo: I-Transformer Ecwiliswe Kuwoyela + i-rectifier enama-winding amaningi

 

Ikesi: Izitimela ze-Fuxing zisebenzisa ama-winding ahlukaniswe kabili (ukucindezela kwe-harmonic okungu-90%)

 

2. Amandla Ezimo Eziphuthumayo eMetro

 

Isidingo: Ukuzisindisa ngesikhathi sokwehluleka

 

Isixazululo: DC110V → DC1200V boost converter

 

Imininingwane: 52.8kW/25s + 26.4kW/60s overload

 

Icala: I-Shanghai Metro Lines 3/4 ithola "ukuvuselelwa kwangaphandle okungenawo ugesi"

 

3. Isitimela saseMaglev kanye neSitimela Sasedolobheni

 

Isidingo: Ubuningi bamandla aphezulu kanye nempendulo

 

Isixazululo: Ubuchwepheshe be-PETT

 

Iphrothokholi ye-CRRC: 2.5kVA/kg amandla obuningi
