Theknoloji ea Bohlokoa ea Li-Transformer tsa Terene: Literene tsa Nakong e Tlang tse Khannang "Pelo e Matla"

'Maraka oa lefats'e oa transformer ea ho hula literene o tla feta $12B ka 2025, moo Chaena e kenyang letsoho ka >40% ha boqapi ba theknoloji bo fetola indasteri bocha

Li-transformer tsa ho hula ka seporo li sebetsa e le lisebelisoa tsa mantlha tsa litsamaiso tsa matla a ho hula ka seporo, li etsa mesebetsi e meraro ea bohlokoa:phetoho ea motlakase, taolo ea motlakase, le tšireletso ea ho itšehla thajanaSengoloa sena se sekaseka kamoo li nolofalletsang ts'ebetso e sebetsang hantle ea literene tse lebelo le phahameng, literene tse tsamaeang ka tlas'a lefatše le litsamaiso tsa maglev ka melao-motheo ea tekheniki, boqapi le lits'ebetso.

 

 

I. Phetoho: Ho tloha ho Methapo-Maqhubu ho ea ho Li-Transformer tsa Elektronike tse Matla

1. Meeli ea Li-Transformer tsa Setso

 

Boholo bo boholo: E lula ka tlase ho 30% ea sebaka sa kariki e ka tlas'a koloi, e fokotsang bokhoni/lebelo la bapalami

 

Siling ea bokhoni: Tahlehelo ea matla ea 5-8%, e mpe le ho feta ka lebelo le tlase

 

Mosebetsi o le mong: Ha e khone ho fumana matla a ho brake a tsosolosang

 

2. Lintlafatso ho Power Electronic Transformers (PET)

Setsi sa CRRC Zhuzhou se thehilePET ea pele ea 25kV lefatšeng ka 2023, ho fihlella:

 

Phokotso ea boima ba 'mele: 20% e nyane, 15% e bobebe (bokgoni bo lekanang)

 

Bokgoni bo phahameng: Bokgoni ba 98.5%, tahlehelo e sa jarisoeng e tlase ka 40%

 

Taolo e bohlale: Di-module tsa IGBT (6.5kV/2kHz) tse nolofalletsang phetoho ya matla ka nako ya sebele

 

II. Mefuta ea Motheo le Papiso ea Tekheniki

III. Theknoloji e Phahameng e Khanyang Phetoho

1. Phetohelo e Phahameng ea Maqhubu le Lintho tse bonahalang

 

Li-core tse se nang sebopeho: Tahlehelo e tlase ea ho se jare mojaro ka 70% (morero oa metro oa Jinpan Tech)

 

Lisebelisoa tsa SiC/GaN: Maqhubu a ho chencha a 10kHz, pholiso e fokotsehile ka 30%

 

Epoxy e fetotsoeng ka nano: Khanyetso e phahameng ea mapetso ka 50%, nako ea bophelo ea lihora tse 400k

 

2. Mekhoa e Bohlale ea O&M

 

DGA ea Inthanete: >95% ho nepahala ha ho bolela esale pele phoso

 

Mafahla a dijithale: Siemens TrafoStar™ e fokotsa litšenyehelo tsa O&M ka 40%

 

3. Ho Nchafatsa Matla a Nchafatsang

 

Li-transformer tsa maikutlo: Khutlisa matla a ho brake ho grid (Shanghai Metro Line 3 e boloka 15%)

 

Ho hula ha tšohanyetso: 110V → 1200V boost converters bakeng sa ho hlaphoheloa ha ho hloleha (sistimi ea Guangyi Electric ea 53kW)

 

IV. Litharollo tse Thehiloeng Maemong

1. Terene e Potlakileng ea ho Tsamaisa Terene

 

Tlhokahalo: Botsitso ho >300km/h

 

Tharollo: Transformer e qoelitsoeng ka oli + sesebelisoa sa ho lokisa lintho tse ngata

 

Nyeoe: Literene tsa Fuxing li sebelisa mapheo a arohaneng habeli (90% harmonic depression)

 

2. Metro Emergency Power

 

Tlhokahalo: Ho ipholosa nakong ea ho hloleha

 

Tharollo: DC110V → DC1200V boost converter

 

Ditlhaloso: 52.8kW/25s + 26.4kW/60s e fetelletseng

 

Nyeoe: Shanghai Metro Lines 3/4 e fihlella "pholiso e se nang motlakase kantle"

 

3. Terene ea Maglev le Intercity

 

Tlhokahalo: Bongata ba matla le karabelo

 

Tharollo: Theknoloji ea PETT

 

Mohlala oa CRRC: 2.5kVA/kg matla a bongata
