Cov Txuj Ci Tseem Ceeb ntawm Rail Traction Transformers: Lub "Lub Plawv Muaj Zog" Tsav Tsheb Ciav Hlau Yav Tom Ntej

Kev lag luam thoob ntiaj teb ntawm kev tsheb ciav hlau transformer yuav tshaj $ 12B los ntawm 2025, nrog rau Tuam Tshoj pab txhawb nqa ntau dua 40% thaum kev tsim kho tshiab hauv kev lag luam

Cov tshuab hluav taws xob traction ua haujlwm ua cov khoom siv tseem ceeb ntawm cov tshuab hluav taws xob traction, ua peb txoj haujlwm tseem ceeb:kev hloov pauv hluav taws xob, kev tswj hwm hluav taws xob, thiab kev tiv thaiv kev cais tawmTsab xov xwm no tshuaj xyuas seb lawv ua li cas thiaj ua rau kev khiav tsheb ciav hlau ceev ceev, subways, thiab maglev systems ua haujlwm tau zoo los ntawm cov ntsiab cai kev siv tshuab, kev tsim kho tshiab, thiab kev siv.

 

 

I. Kev Hloov Pauv: Los Ntawm Kab Zaus Mus Rau Lub Tshuab Hloov Hluav Taws Xob Muaj Zog

1. Cov Kev Txwv ntawm Cov Transformers Ib Txwm Muaj

 

Loj heev: Siv ntau tshaj 30% ntawm qhov chaw hauv qab lub tsheb thauj khoom, txwv qhov peev xwm ntawm cov neeg caij tsheb / qhov ceev

 

Qab nthab ua haujlwm tau zoo: 5-8% kev poob zog, qhov phem dua ntawm qhov ceev qis

 

Ib qho kev ua haujlwm: Tsis tuaj yeem rov qab tau lub zog nres tsheb rov qab

 

2. Kev Tshawb Fawb Tshiab hauv Kev Hloov Pauv Hluav Taws Xob (PET)

Lub Koom Haum CRRC Zhuzhou tau tsim tsathawj lub ntiaj teb 25kV PET hauv xyoo 2023, ua tiav:

 

Txo qhov hnyavMe dua 20%, sib dua 15% (muaj peev xwm tib yam)

 

Kev ua haujlwm zoo: 98.5% kev ua haujlwm zoo, 40% qis dua tsis muaj kev poob khoom

 

Kev tswj hwm ntseIGBT modules (6.5kV/2kHz) ua kom muaj kev hloov kho lub zog tiag tiag

 

II. Cov Hom Core & Kev Sib Piv Txog Kev Siv Tshuab

III. Cov Txuj Ci Tshiab Uas Tsav Kev Hloov Pauv

1. Kev Hloov Pauv Zaus Siab & Khoom Siv

 

Cov tub ntxhais tsis muaj zog: 70% qis dua qhov tsis muaj kev poob (Jinpan Tech metro project)

 

Cov khoom siv SiC / GaN: 10kHz hloov zaus, 30% tsawg dua txias

 

Nano-modified epoxy: Tsis kam tawg ntau dua 50%, lub neej ua haujlwm ntev txog 400k teev

 

2. Cov Txheej Txheem Ua Haujlwm thiab Kev Tswj Xyuas Ntse

 

DGA hauv online: >95% qhov tseeb ntawm kev kwv yees qhov yuam kev

 

Cov menyuam ntxaib digitalSiemens TrafoStar™ txo cov nqi O&M los ntawm 40%

 

3. Kev Siv Zog Rov Qab Los Ua Dua Tshiab

 

Cov khoom siv hloov pauv tswv yimRov qab lub zog nres rau hauv lub grid (Shanghai Metro Line 3 txuag tau 15%)

 

Kev rub thaum muaj xwm ceev: 110V → 1200V boost converters rau kev rov qab ua tsis tiav (Guangyi Electric's 53kW system)

 

IV. Cov Kev Daws Teeb Meem Raws Li Qhov Xwm Txheej

1. Kev Siv Tsheb Ciav Hlau Ceev

 

Qhov Yuav Tsum Tau UaKev ruaj khov ntawm >300km/h

 

Kev daws teeb meem: Roj-Immersed Transformer + ntau lub rectifier

 

Cov Ntaub Ntawv: Cov tsheb ciav hlau Fuxing siv cov xov hluav taws xob sib cais ob zaug (90% kev tswj hwm harmonic)

 

2. Lub Hwj Chim Thaum Muaj Xwm Ceev Hauv Metro

 

Qhov Yuav Tsum Tau Ua: Kev cawm tus kheej thaum muaj kev ua tsis tiav

 

Kev daws teeb meemDC110V → DC1200V lub tshuab hloov pauv zog

 

Cov Lus Qhia Tshwj Xeeb: 52.8kW / 25s + 26.4kW / 60s overload

 

Cov Ntaub Ntawv: Shanghai Metro Kab 3/4 ua tiav "kev rov qab los ntawm sab nraud tsis muaj hluav taws xob"

 

3. Maglev & Tsheb Ciav Hlau Sib Nraus

 

Qhov Yuav Tsum Tau Ua: Lub zog ceev ceev & kev teb ceev ceev

 

Kev daws teeb meemSiv tshuab PETT

 

CRRC qauv: 2.5kVA/kg zog ceev
