Izityalo zeekhemikhali:Ukunika amandla ii-electrolyzers kunye nee-compressors ezinkulu, ezifana6-10kVii-transformers ezizinikeleyo zokuvelisa i-chlor-alkali.

 

2 "Iadaptha echanekileyo" yoMveliso oPhambili

 

Ukwenziwa kwee-semiconductor:Oomatshini bokugcada i-wafer badingai-harmonic esezantsi kakhuluamandla aphezulu e-voltage (umz., udidi lwe-40kV), kunye nee-transformers ezihlangabezana nemigangatho engqongqo ye-THD

 

Ukusika nge-laser:Iileyiza zeCO₂ zixhomekeke kuzo20-50kVii-transformers ze-high-voltage ukuvelisa i-plasma, apho ukuchaneka kuchaphazela ngokuthe ngqo umgangatho wokusika.

 

III. Utshintsho kwiMandla aHlaziyiweyo

1. "Ibhuloho yeGridi" yamandla elanga nawomoya

 

Iifama zelanga:Ukuguqula i-0.8-1.5kV DC output ukusuka kwi-PV arrays ukuya kwi-35kV AC, uze unyuke uye kwi-132kV grid voltage (umz., iprojekthi yelanga ye-2GW kaNingxia).

 

Umoya ophuma elwandle:Ukusetyenziswa kwezikhululo ezingaphantsi komhlaba ezingama-66kVi-resin ephosiweyo Isiguquli sohlobo olomileyosukuze kuxhathiswe inkungu yetyuwa kwaye kusebenze ngaphandle kokugcinwa.

 

2. "I-Energy Hub" yeeNkqubo zokuGcina

 

Indawo yokugcina ibhetri:Iitransformer zevolthi ephezulu ziyasebenzaUguqulelo lwe-DC/AC olubhekisa kwicala elinyeyokulawula igridi rhoqo (umz., ii-transformers ze-2.5MVA zeTesla Megapack).

 

 

IV. Inkxaso Ebalulekileyo Kwizicelo Ezikhethekileyo

1. "Umgcini woKhuseleko" weZixhobo zonyango

 

Ukuxilongwa kwemifanekiso:Oomatshini be-X-ray kunye ne-CT bafuna80-150kVizixhobo zombane, kunye neetransformer ezithobelaImigangatho yezonyango ye-IEC 60601yokukhusela ubushushu kunye ne-EMC.

 

Izixhobo zonyango:Izikhawulezisi ezicwangcisiweyo zokusetyenziswa kwe-radiotherapyii-transformers ze-pulse ezine-voltage ephezulu(impendulo ye-nanosecond) enokunyamezela iimpazamo ezingaphantsi kwe-0.1%.

 

2 "Isixhobo Sokuchaneka" soPhando lwezeNzululwazi
