Ukadaulo Wapakati wa Sitima Zosinthira Sitima: "Mtima Wamphamvu" Woyendetsa Sitima Zamtsogolo

Msika wapadziko lonse wa transformer yonyamula sitima udzapitirira $12 biliyoni pofika chaka cha 2025, pomwe China yathandizira >40% pamene zatsopano zaukadaulo zikukonzanso makampaniwa

Ma transformer otengera mphamvu ya sitima amagwira ntchito yofunika kwambiri pamakina amphamvu otengera mphamvu ya sitima, ndipo amagwira ntchito zitatu zofunika kwambiri:kusintha kwa mphamvu, malamulo a magetsi, ndi chitetezo chodzipatulaNkhaniyi ikufotokoza momwe zimathandizira kuti sitima zapamtunda zothamanga kwambiri, sitima zapansi panthaka, ndi maginito zigwire bwino ntchito pogwiritsa ntchito mfundo zaukadaulo, zatsopano, ndi ntchito.

 

 

I. Chisinthiko: Kuchokera ku Mafupipafupi a Mizere kupita ku Ma Transformer Amagetsi Amphamvu

1. Zofooka za Transformers Zachikhalidwe

 

Kukula kwakukulu: Amakhala ndi malo okwana 30% a pansi pa galimoto, zomwe zimachepetsa kuchuluka kwa anthu/liwiro

 

Denga logwira ntchito bwino: Kutaya mphamvu ndi 5-8%, koipa kwambiri pa liwiro lotsika

 

Ntchito imodzi: Singathe kubwezeretsa mphamvu yobwezeretsa mabuleki

 

2. Kupambana mu Power Electronic Transformers (PET)

CRRC Zhuzhou Institute idakhazikitsaPET yoyamba ya 25kV padziko lonse mu 2023kukwaniritsa:

 

Kuchepetsa thupi: 20% yocheperako, 15% yopepuka (mphamvu yofanana)

 

Kuchita bwino kwambiri: 98.5% ya magwiridwe antchito, 40% yotsika yotaya popanda katundu

 

Kulamulira mwanzeru: Ma module a IGBT (6.5kV/2kHz) omwe amalola kusintha mphamvu nthawi yeniyeni

 

II. Mitundu Yaikulu & Kuyerekeza Kwaukadaulo

III. Ukadaulo Wamakono Ukusintha Zinthu

1. Kusintha Kwambiri kwa Ma Frequency & Zinthu Zakuthupi

 

Mitsempha ya Amorphous: Kutaya kosanyamula katundu ndi 70% (pulojekiti ya Jinpan Tech metro)

 

Zipangizo za SiC/GaN: 10kHz switching frequency, 30% kuziziritsa kochepa

 

Epoxy yosinthidwa pang'ono: Kukana kwa ming'alu kwapamwamba kwambiri kwa 50%, nthawi ya moyo ya maola 400k

 

2. Makina Anzeru a O&M

 

DGA Yapaintaneti: >95% kulondola kwa kulosera zolakwika

 

Mapasa a digitoSiemens TrafoStar™ yachepetsa ndalama zogulira zinthu ndi 40%

 

3. Kubwezeretsanso Mphamvu Zobwezeretsa

 

Ma transformer a mayankho: Kubwezeretsa mphamvu ya mabuleki ku gridi (Shanghai Metro Line 3 imasunga 15%)

 

Kugwira ntchito mwadzidzidzi: 110V → 1200V boost converters kuti zibwezeretse kulephera (dongosolo la Guangyi Electric la 53kW)

 

IV. Mayankho Ochokera ku Zochitika

1. Sitima Yothamanga Kwambiri Yoyenda

 

ChofunikiraKukhazikika pa >300km/h

 

Yankho: Transformer Yomizidwa ndi Mafuta + chosinthira chozungulira chambiri

 

Mlanduwu: Sitima zoyendera pogwiritsa ntchito fuxing zimagwiritsa ntchito ma windings ogawanika kawiri (90% harmonic suppression)

 

2. Metro Emergency Power

 

ChofunikiraKudzipulumutsa nokha panthawi yolephera

 

Yankho: DC110V → DC1200V boost converter

 

Zofotokozera: 52.8kW/25s + 26.4kW/60s yodzaza

 

Mlandu: Shanghai Metro Lines 3/4 yapeza "kubwezeretsa kwakunja popanda magetsi"

 

3. Sitima ya Maglev ndi Intercity

 

Chofunikira: Kuchuluka kwa mphamvu ndi mayankho

 

Yankho: ukadaulo wa PETT
