Ngā Hangarau Matua o ngā Whakawhitiwhiti Rerewē: Te "Manawa Mana" e Ārahi ana i ngā Tereina o te Ao

Ka neke atu i te $12B te mākete whakawhiti hiko tereina o te ao i te tau 2025, me Haina e whai wāhi ana ki te >40% i te mea kei te huri te ahumahi i ngā auahatanga hangarau

Ko ngā whakawhiti hiko tereina te taputapu matua o ngā pūnaha hiko hiko, e toru ngā mahi nui e mahia ana:te hurihanga hiko, te whakahaere ngaohiko, me te tiakitanga wehe. Ka tātarihia e tēnei tuhinga te huarahi e taea ai e rātou te whakahaere pai i ngā tereina tereina, ngā ara raro whenua, me ngā pūnaha maglev mā roto i ngā mātāpono hangarau, ngā auahatanga, me ngā tono.

 

 

I. Te Whanaketanga: Mai i te Auautanga Raina ki ngā Whakawhiti Hikohiko Mana

1. Ngā Here o ngā Transformers Tuku Iho

 

Rahi nui: E nohoia ana >30% o te wāhi i raro i te waka, e whakawhāiti ana i te kaha/tere o ngā pāhihi

 

Te tuanui whai hua5-8% te ngaronga pūngao, kino rawa atu i ngā tere iti

 

Mahi-kotahiKāore e taea te whakaora i te kaha aukati whakaora

 

2. Ngā Huarahi Hou i roto i ngā Whakawhiti Hiko Mana (PET)

I whakawhanakehia e te CRRC Zhuzhou Institute tete PET 25kV tuatahi o te ao i te tau 2023, te whakatutuki:

 

Te whakaiti i te taumaha: 20% iti ake, 15% mama ake (he rite tonu te kaha)

 

Teitei o te whai huatanga98.5% te pai o te mahi, 40% te iti iho o te ngaronga kore-kawenga

 

Mana whakahaere atamaiNgā kōwae IGBT (6.5kV/2kHz) e āhei ai te whakarerekētanga mana wā-tūturu

 

II. Ngā Momo Matua me te Whakataurite Hangarau

III. Ngā Hangarau Hou e Ārahi ana i te Huringa

1. Te Huringa Auau-Teitei me te Rauemi

 

Ngā matua kore āhua: 70% te iti iho o te ngaronga kore-uta (kaupapa metro Jinpan Tech)

 

Ngā taputapu SiC/GaN: Auautanga whakawhiti 10kHz, 30% te iti iho o te whakamatao

 

Epoxy kua whakarerekētia ki te nano50% te ātete pakaru teitei ake, 400k-haora te roa o te ora

 

2. Ngā Pūnaha O&M Atamai

 

DGA Ipurangi: >95% te tika o te matapae hapa

 

Ngā māhanga matihikoKa whakahekehia e Siemens TrafoStar™ ngā utu whakahaere me te tiaki mā te 40%

 

3. Te Hangarua Pūngao Whakaora

 

Ngā whakawhiti urupareWhakahokia te kaha aukati ki te whatunga (ka penapenahia e te Raina Metro 3 o Shanghai te 15%)

 

Te kukume ohorere: Ngā kaitahuri whakanui 110V→1200V mō te whakaora i te rahunga (pūnaha 53kW a Guangyi Electric)

 

IV. Ngā Otinga e Hangai ana ki te Horopaki

1. Te Aroturuki Rerewē Tere-Tiketike

 

WhakaritengaTe pumau i te >300km/h

 

Otinga: Whakawhiti Hinu-Rukuhia + whakatikatika maha-takahuri

 

Take: Ka whakamahia e ngā tereina Fuxing ngā takai takirua-wehe (90% te pehitanga o te harmonic)

 

2. Te Hiko Āwhata o Metro

 

WhakaritengaTe whakaora i a koe anō i ngā wā e hinga ana

 

Otinga: DC110V→DC1200V pūtahuri whakanui

 

Ngā Whakatakotoranga: 52.8kW/25s + 26.4kW/60s taumaha rawa

 

Take: Ka tutuki i ngā Raina Metro Shanghai 3/4 te "whakaora kore hiko o waho"

 

3. Rerewē Maglev me te Rerewē ā-Taone

 

WhakaritengaTe kaha o te mana me te urupare

 

OtingaHangarau PETT

 

Tauira CRRC: 2.5kVA/kg te mātotoru o te mana
