Iiteknoloji eziphambili zeeTransformers zeTraction Rail: "Intliziyo enamandla" eqhuba oololiwe bexesha elizayo

Imakethi yehlabathi ye-transformer ye-traction kaloliwe iza kudlula i-$12B ngo-2025, apho iTshayina inegalelo elingaphezulu kwama-40% njengoko izinto ezintsha zobuchwepheshe zitshintsha imboni

Iitransformer zetraction kaloliwe zisebenza njengezixhobo eziphambili zeenkqubo zamandla etraction, zenza imisebenzi emithathu ebalulekileyo:ukuguqulwa kwamandla, ukulawulwa kwevolthi, kunye nokukhuselwa kokuzihlukanisaEli nqaku lihlalutya indlela ezivumela ngayo ukusebenza kakuhle kweenkqubo zikaloliwe ohamba ngesantya esiphezulu, iinqanawa ezingaphantsi komhlaba, kunye neenkqubo ze-maglev ngokusebenzisa imigaqo yobugcisa, izinto ezintsha, kunye nokusetyenziswa kwazo.

 

 

I. Uphuhliso: Ukusuka kwiMigca-Ubuninzi ukuya kwi-Power Electronic Transformers

1. Imida yeeTransformers zeMveli

 

Ubungakanani obukhulu: Ihlala ngaphezulu kwe-30% yendawo yesithuthi esingaphantsi kwenqwelo moya, nto leyo ethintela umthamo/isantya sabakhweli

 

Uphahla olusebenzayo: Ukulahleka kwamandla nge-5-8%, kubi ngakumbi ngesantya esiphantsi

 

Umsebenzi omnye: Ayikwazi ukubuyisa amandla okuvuselela ukubhuleka

 

2. Ukuphumelela kwiiTransformers ze-Elektroniki ezisebenza ngamandla (i-PET)

I-CRRC Zhuzhou Institute iphuhlise i-I-PET yokuqala ye-25kV kwihlabathi ngo-2023, ukufezekisa:

 

Ukunciphisa ubunzima: 20% incinci, 15% ilula (umthamo ofanayo)

 

Ukusebenza kakuhle okuphezulu: Ukusebenza kakuhle kwe-98.5%, ukulahleka komthwalo okuphantsi kwe-40%

 

Ulawulo olukrelekrele: Iimodyuli ze-IGBT (6.5kV/2kHz) ezivumela uhlengahlengiso lwamandla ngexesha langempela

 

II. Iintlobo eziphambili kunye nothelekiso lobuchwephesha

III. Ubuchwepheshe obuPhezulu buqhuba utshintsho

1. Uguquko Oluphezulu Lwexesha Eliqhelekileyo Nezinto Eziphathekayo

 

Ii-cores ezi-Amorphous: Ilahleko engaphantsi kwe-70% ngaphandle komthwalo (iprojekthi ye-Jinpan Tech metro)

 

Izixhobo zeSiC/GaN: I-10kHz switching frequency, ukupholisa okuncinci ngama-30%

 

I-epoxy eguqulweyo kancinane: Ukumelana nokuqhekeka okuphezulu ngama-50%, ubomi bexesha elingama-400k iiyure

 

2. Iinkqubo ze-Smart O&M

 

I-DGA ekwi-intanethi: >95% ukuchaneka kokuqikelela iimpazamo

 

Amawele edijithali: I-Siemens TrafoStar™ yehlisa iindleko ze-O&M ngama-40%

 

3. Ukuphinda kusetyenziswe amandla avuselelayo

 

Iitransformer zempendulo: Buyisela amandla okubhuleka kwigridi (iShanghai Metro Line 3 igcina i-15%)

 

Ukutsala okungxamisekileyo: 110V → 1200V boost converters zokubuyisela ukungasebenzi kakuhle (inkqubo ye-53kW kaGuangyi Electric)

 

IV. Izisombululo Ezisekelwe Kwimeko

1. Indlela Yokutsala Uloliwe Ohamba Ngesantya Esiphezulu

 

Imfuneko: Uzinzo kwi >300km/h

 

Isisombululo: Isiguquli esintywiliselwa kwioyile + i-rectifier enezimbobo ezininzi

 

Ityala: Oololiwe be-Fuxing basebenzisa ii-windings eziqhekekileyo ezimbini (90% harmonic depression)

 

2. Umbane oNgxamisekileyo weMetro

 

Imfuneko: Ukuzihlangula ngexesha lokusilela

 

Isisombululo: DC110V → DC1200V boost converter

 

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

 

Ityala: I-Shanghai Metro Lines 3/4 ifezekisa "ukubuyiselwa ngaphandle kombane"

 

3. Isitimela saseMaglev kunye neSixeko esiPhakathi

 

Imfuneko: Ubuninzi bamandla kunye nempendulo

 

Isisombululo: Itekhnoloji yePETT

 

Iprototype yeCRRC: 2.5kVA/kg uxinano lwamandla
