Pamberi pemagetsi ekufambisa tekinoroji, tsvakurudzo itsva, development, uye kushandiswa kwe750-kilovolt (KV) ultra-high voltage (UHV) cable system yawana kutariswa kwakanyanya.
Background uye Overview
Munguva pfupi yapfuura, China Three Gorges Kuvaka Boka, mukubatana nemabhizinesi akadai seQingdao Han Cable Co., Changzhou Cable Technology, uye China Electric Power Research Institute, kubudirira kugadzirwa a 750 kV UHV cable system. Iyi sisitimu yapasa nyika chigadzirwa chitupa, kuwedzera kusimbisa kushanda kwayo uye kuvimbika. Kubudirira uku hakungomiriri kubudirira kwakakosha kuChina mukufambiswa kwemagetsi akakwira-voltage asi zvakare kunomisa chinzvimbo cheChina semutungamiri wetekinoroji muindasitiri yetambo yeUHV.. Iyo sisitimu yekugashira yeese ari maviri flat uye corrugated aluminium sheath tekinoroji inobata kukosha kwepasirese., kuseta bhenji rekufambiswa kwemagetsi uye kusimudzira grid kune dzimwe nyika.
Tekinoroji Kubudirira: Core Innovations uye Zvakabudirira zve 750 kV UHV Cable System
Kubudirira kweizvi 750 kV UHV tambo system inoguma kubva kune akawanda tekinoroji kubudirira. Iye R&D timu yakakunda matambudziko akakosha ehunyanzvi ane chekuita neflat uye makora ealuminium sheaths, kuve nechokwadi chekudzivirira uye kugadzikana pa-ultra-high voltages. Ivo zvakare vakagadzira mvura-yakazadzwa insulated composite casing terminations uye yakaoma-mhando insulated GIS kuguma., kupa kuchengetedzwa kwepamusoro uye kugadzikana kwegadziriro.
Zvinoshamisa, iyo sisitimu yakapfuura kuyedzwa kwakasimba paChina Magetsi Power Indasitiri Yemagetsi Equipment Quality Inspection uye Testing Center, kuva wekutanga 750 kV UHV tambo yetambo yekupedzisa kuyedzwa kwakazara kweese ari maviri flat uye corrugated aluminium sheaths.. Kubudirira uku hakungofambisire mberi UHV tambo tekinoroji asiwo inopa ruzivo rutsva rwekufambisa kwemagetsi mune mamwe matunhu..
Technical Innovations of the 750 kV UHV Cable System
Panguva yekuvandudzwa kwe 750 kV UHV cable system, chikwata chakawana hutsva munzvimbo dzakawanda dzehunyanzvi. Iyi purojekiti ine chinangwa chekupa mhinduro inoshanda kune yakakura-chiyero, kureba-kure-kure kufambisa simba kuti uve nechokwadi chekugadzikana uye kuchengeteka kwepamusoro-voltage transmission. Makiyi ekugadzira tekinoroji anosanganisira:
Kubudirira muFlat uye Corrugated Aluminium Sheath Technologies
The the 750 kV sisitimu inosanganisa ese ari maviri flat uye makora aruminiyamu sheaths, kuvandudza kusimba kwetambo uye kugadzikana kuzadzisa zvakasiyana siyana zvinodiwa kwezvakatipoteredza. Iyo flat aluminium sheath yakasimba uye yakareruka, akakodzera kuendesa simba kure-kure munzvimbo dzakananga. Zvichakadaro, iyo corrugated aluminium sheath's flexibility inokodzera mamiriro apo tambo dzinoda kubhenda kwakakura.. Izvi zvitsva zvinosimudzira tambo yemagetsi zvivakwa uye inowedzera kusimba kwayo munzvimbo dzakaoma.
Kuvandudzwa kweLiquid-Yakazara Insulated Composite Casing Kumiswa
Iko kuvandudzwa kwemvura-yakazadzwa insulated composite casing kuguma kunoratidza hunyanzvi hutsva mukati me 750 kV UHV cable system. Yakagadzirirwa kupa insulation uye chisimbiso mutambo system, kugumisa uku kunoshandisa zvinhu zvakazadzwa-mvura kuendesa yakanakisa insulation, kuderedza kupisa kurasikirwa nekuda kwepamusoro voltage uye kuwedzera kudzikamisa tambo yekushanda.
Innovative Dhizaini yeDy-Type Insulated GIS Kugumiswa
Iyo yakaoma-mhando insulated gasi-insulated switchgear (GIS) yekumisa dhizaini yekuvandudza inowedzera huwandu hwekushandisa kwetambo system. Kushandisa yakakwirira-chisimbiso zvinhu uye yakasarudzika dhizaini zvinhu, kugumiswa uku kunowedzera simba rekuchengetedza system, kuvandudza yakazara tambo kuchengetedza uye kupa yakavimbika sarudzo ye 750 kV voltage-level simba rekufambisa.
Kubudirira Kupedzwa Kweyakakwana Rudzi Kuedzwa
Yese yakakosha tekinoroji uye chikamu mukati meiyo 750 kV tambo system yakamboyedza mhando yakakura, kuongorora kupisa kwayo kupisa, Simba resimba, uye kugadzikana munzvimbo dzakakwirira-voltage. Kubudirira kwebvunzo idzi kunoratidza kushanda kwehurongwa munzvimbo dzakasiyana siyana dzekutapurirana uye kunosimbisa kuvimbika kwayo..
Market Demand uye Global Application ye 750 kV UHV Cable
Kumashure kweUHV Cable application
