Matekinoroji Akakosha eVashanduri veTracing Traction Rail: "Power Heart" Inotyaira Zvitima Zvemangwana

Musika wepasi rose we transformer ye traction njanji uchapfuura $12 Bhiriyoni panosvika 2025, China ichipa >40% sezvo hunyanzvi hwetekinoroji huri kuchinja indasitiri iyi

Matransformer ekufambisa njanji anoshanda semudziyo mukuru wemasisitimu esimba rekufambisa, achiita mabasa matatu akakosha:kushandurwa kwesimba, mutemo wemagetsi, uye dziviriro yekuzviparadzanisaChinyorwa chino chinoongorora kuti zvinoita sei kuti njanji dzinomhanya zvikuru, migwagwa yepasi pevhu, uye masisitimu emagetsi ashande zvakanaka kuburikidza nemisimboti yehunyanzvi, hunyanzvi, uye mashandisirwo azvo.

 

 

I. Kushanduka-shanduka: Kubva paKuwanda kweMitsetse kuenda kuMasimba eMagetsi emagetsi

1. Miganhu yeVashanduri Vechinyakare

 

Hukuru hwakakura: Inogara pasi pechingoro chiri pasi pemotokari, zvichiita kuti vatasvi vasakwanise kufamba/kumhanya zvakanyanya.

 

Denga rekushanda zvakanaka: Kurasikirwa nesimba ne5-8%, kwakaipisisa kana kumhanya kwakaderera

 

Basa rimwe chete: Haikwanise kudzoreredza simba rekugadzirisa mabhureki

 

2. Kubudirira muSimba reMagetsi emagetsi (PET)

CRRC Zhuzhou Institute yakagadzira chirongwa che25kV PET yekutanga pasi rose muna 2023, kuzadzisa:

 

Kuderedza huremu: 20% diki, 15% yakareruka (yakaenzana)

 

Kushanda zvakanyanya: Kushanda zvakanaka kwe98.5%, 40% yakaderera kurasikirwa pasina mutoro

 

Kudzora kwakangwara: Mamodule eIGBT (6.5kV/2kHz) anogonesa kugadzirisa simba panguva chaiyo

 

II. Mhando dzeMashoko & Kuenzanisa kweTechnical

III. Tekinoroji Dzazvino Dzinoshandura Zvinhu

1. Kuchinja-chinja kweMazuva uye Zvinhu

 

Makori eAmorphous: 70% yakaderera kurasikirwa pasina mutoro (Jinpan Tech metro project)

 

Zvishandiso zveSiC/GaN: 10kHz switching frequency, 30% kutonhora kushoma

 

Epoxy yakagadziriswa neNano: 50% yakakwira yekuramba kupwanyika, hupenyu hwe400k-awa

 

2. Masisitimu eSmart O&M

 

DGA Yepamhepo: >95% kunyatsofanotaura zvikanganiso

 

Mapatya edhijitari: Siemens TrafoStar™ inoderedza mitengo yeO&M ne40%

 

3. Kudzokorodza Simba Rinodzokorodza

 

Matransformer emhinduro: Dzorera simba remabhureki kugrid (Shanghai Metro Line 3 inochengetedza 15%)

 

Kubata kwekukurumidza: 110V → 1200V boost converters kuti idzore kutadza (system yeGuangyi Electric ye53kW)

 

IV. Mhinduro Dzakavakirwa Pamamiriro Ezvinhu

1. Kufamba kweNjanji Inomhanya Zvikuru

 

Chinodiwa: Kugadzikana pa >300km/awa

 

Mhinduro: Transformer Inonyudzwa muOiri + chinogadzirisa mavhiri akawanda

 

Nyaya: Zvitima zvinofambisa mhepo zvinoshandisa mawindings maviri (90% harmonic depression)

 

2. Metro Emergency Power

 

Chinodiwa: Kuzvinunura panguva yekukundikana

 

Mhinduro: DC110V →DC1200V boost converter

 

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

 

Nyaya: Shanghai Metro Lines 3/4 yawana "kudzoreredza kunze kwemagetsi pasina magetsi"

 

3. Njanji yeMaglev neIntercity

 

Chinodiwa: Simba guru uye mhinduro

 

Mhinduro: Tekinoroji yePETT

 

Muenzaniso weCRRC: 2.5kVA/kg simba kuwanda
