Ikoranabuhanga ry'ingenzi rya Transformers zo Gutwara Gari ya Moshi: "Umutima w'Imbaraga" Utwara Gari za Moshi z'ejo hazaza

Isoko ry'isi ry'ibikoresho bihindura imikorere ya gari ya moshi rizarenga miliyari 12 z'amadolari bitarenze umwaka wa 2025, aho Ubushinwa butanga >40% mu gihe udushya mu ikoranabuhanga tuvugurura imikorere y’inganda

Transformateur zikoresha amashanyarazi ya gari ya moshi zikora nk'ibikoresho by'ingenzi bya sisitemu y'ingufu zikoresha amashanyarazi, zikora imirimo itatu y'ingenzi:guhindura ingufu, kugenzura amashanyarazi, no kurinda kwitandukanyaIyi nkuru isesengura uburyo ituma habaho imikorere myiza ya gari ya moshi yihuta cyane, gari ya moshi zo munsi y'ubutaka, na sisitemu za maglev binyuze mu mahame ya tekiniki, udushya, n'ikoreshwa ryayo.

 

 

I. Iterambere: Kuva ku murongo kugeza ku byuma bihindura amashanyarazi by'ikoranabuhanga

1. Inzitizi z'Abahindura Ibikoresho gakondo

 

Ingano nini: Ifite umwanya uri hejuru ya 30% by'igare rinini, bigatuma abagenzi badashobora kwihuta/badashobora gutwara imodoka

 

Igisenge cy'imikorere myiza: Ingufu zigabanukaho 5-8%, mbi kurushaho iyo umuvuduko uri hasi

 

Umukorere umwe: Ntishobora kugarura ingufu zo kugarura feri

 

2. Impinduka mu byuma bihindura amashanyarazi (PET)

Ikigo cya CRRC Zhuzhou cyateguyePET ya mbere ya 25kV ku isi muri 2023, kugera kuri:

 

Kugabanya ibiro: 20% nto, 15% yoroheje (ubushobozi bumwe)

 

Umusaruro mwinshi: Ingufu za 98.5%, 40% ku gihombo kidatwara imizigo

 

Igenzura ry'ubwenge: Module za IGBT (6.5kV/2kHz) zituma habaho ihinduka ry'ingufu mu gihe nyacyo

 

II. Ubwoko bw'ingenzi n'igereranya rya tekiniki

III. Ikoranabuhanga Rigezweho Rituma habaho Impinduka

1. Impinduramatwara y'Ibintu n'Ibintu Bikomeye

 

Amabara y'inyongera: 70% by'igihombo kidatwara imizigo (umushinga wa Jinpan Tech metro)

 

Ibikoresho bya SiC/GaN: 10kHz switching frequency, 30% by'ubukonje buke

 

Epoxy yahinduwe na nano: Ubudahangarwa bw'amacandwe buri hejuru ya 50%, igihe cyo kubaho amasaha 400k

 

2. Sisitemu z'ubwenge za O&M

 

DGA yo kuri interineti: >95% ukuri kw'ibizavugwa mu gihe cy'ikosa

 

Impanga zo mu bwoko bwa digitale: Siemens TrafoStar™ yagabanyije ikiguzi cya O&M ho 40%

 

3. Gusubiramo ingufu zikoreshwa mu kongera gukoresha imbaraga

 

Transformateurs z'ibitekerezo: Gusubiza ingufu za feri kuri grid (Shanghai Metro Line 3 izigama 15%)

 

Gufata ibintu mu gihe cy'ibiza: 110V → 1200V boost converters zo gusubiza ikibazo (sisitemu ya Guangyi Electric ya 53kW)

 

IV. Ibisubizo bishingiye ku miterere y'ibintu

1. Inzira ya gari ya moshi yihuta cyane

 

Ibisabwa: Ituze riri kuri >300km/h

 

Umuti: Transformer ikoreshwa mu mavuta + imashini ikosora ibintu byinshi

 

Icyitonderwa: Gari za moshi zikoresha uburyo bwo gufunga imiyoboro bubiri (90% harmonic depressure)

 

2. Metro Emergency Power

 

IbisabwaKwikiza mu gihe cy'ibyago

 

Umuti: DC110V→ DC1200V boost converter

 

Ibisobanuro: 52.8kW/25s + 26.4kW/60s umutwaro urenze urugero

 

Urubanza: Shanghai Metro Lines 3/4 zageze ku "gusubirana inyuma nta ngufu z'amashanyarazi"

 

3. Gari ya moshi ya Maglev n'Imijyi

 

Ibisabwa: Ubucucike bw'ingufu nyinshi n'uburyo bwo gusubiza

 

Umuti: Ikoranabuhanga rya PETT

 

Icyitegererezo cya CRRC: Ubucucike bw'ingufu bwa 2.5kVA/kg
