Sei Matambo Epamusoro-Voltge Asingakwanisi Kuvigwa Pasi Pevhu?

Chii chinonzi High-Voltage Cable?

Ultra-yakakwirira voltage transmission inoreva kushandiswa kwe 500 kV-1000 kV voltage mazinga ekufambisa magetsi.

Kana iyo 220 kV kutapurirana index ndiko 100%, iyo hama yekudyara pakiromita yeUHV kutapurirana, mutengo wakaenzana pa kilowatt-awa yekufambisa magetsi makiromita zana uye kushandiswa kwezvinhu zvesimbi, etc., dzakaderedzwa zvakanyanya, uye chiyero chekushandiswa kwemukoto corridor chakavandudzwa zvakanyanya.

Muhupenyu hwedu hwemazuva ese, isu tinogona kazhinji kuona iyo yepamusoro-yepamusoro voltage transmission project, kana tafunga nezvemubvunzo: sei isingaite seguta repasi tambo, high-voltage magetsi tambo dzose dzakavigwa pasi pevhu?

Idzo tambo dzepasi pevhu dzazvino dzinowanzove dzakaderera voltage level.

Kufambiswa kwemitsara ine mazinga akakwirira emagetsi kunowanzova pamusoro, iyo inonyanya kukosha yemutengo uye tekinoroji. 　　

Tambo dzepasi pevhu dzakanyanya kuomarara kupfuura chimiro chemitsetse yepamusoro, nepamusoro hunyanzvi zvinodiwa, kugadzira, nematambudziko ekuvaka, pamwe chete netambo yakavigwa pasi pevhu, hazvisi nyore kuwana zvikanganiso, overhaul, uye kuchengetedza zvakare kwakaoma zvakanyanya.

Uye maererano nemutengo, kazhinji, iyo yakafanana voltage level yepasi pevhu inodhura 3 kuti 5 nguva dzakakwirira kudarika mitsetse yepamusoro. 　　

Hunhu Hwepamusoro-Voltage Transmission Lines

Zvikuru sei, mitsetse yedu yakajairwa yakakwirira-voltage level inowanzoshandiswa pakufambisa kureba.

Kana tambo dzepasi pevhu dzichishandiswa, kunyanya kutapurirana kure-kure nguva nenguva kuburikidza nenzvimbo dzakaoma, mutengo uye zvinodiwa zvehunyanzvi zvinogona kutokwira mudenga. 　　

Pane rimwe divi, uyewo pasi tambo itself is inherently “hard”.

Mitsetse yepamusoro mumhepo mumamiriro akanaka ekupisa, nepo mhepo yakatenderedza tambo yepasi pevhu isingayerere, zvakaoma kubvisa kupisa, iyo inonyanya kudzora mwero wemagetsi epasi pevhu anogona kutamisa.

Chinhu chakakosha ndechekuti ultra-high voltage transmission haina kukwanisa kuwana inoshanda yekudzivirira zvinhu kuita ganda rekunze. insulation layer yewaya.

Saka, Ultra-high voltage waya dzakashama uye hadzigone kuvigwa tenga pasi pevhu.

Pane akagoverwa capacitances kumativi waya, kuburikidza iyo ikozvino inogona kubuda kunze.

Kune rumwe rutivi kuwedzera kushandiswa, pane rimwe divi, kana chero mhuka yakavharwa, pachavawo nengozi ye electrocution.

Mhepo inodzivirira, asi nyika mufambisi. Mumitsetse yepamusoro, zvakakwana kuisa waya zvakananga ipapo.

Asi pasi pevhu, wedzera dhizaini yeganda rekudzivirira kunze kwewaya, zvimwe, magetsi muwaya haana kuenda kure, uye kubuda kwemagetsi kuchadonha zvese zvasara.

Kazhinji kutaura, mutengo wetambo dzepasi pevhu dzeyero yevoltage imwechete ichave kakawanda kana makumi enguva iyo yematambo emhepo akakwira-voltage..

Ultra-yakakwirira voltage tambo dzakavigwa pasi pevhu dzine zvese zvekuchengetedza uye matambudziko ehupfumi.

Kana kukanganisa kukaitika, kuongorora kwayo nekugadzirisa tambo ipurojekiti yakakura kwazvo uye haigone kukanda nekutendeuka.

Saka, tambo dzeUHV dzazvino dzinofanirwa kusungirirwa kumusoro mumhepo.

Pfupiso

Underground cable conductors outsourced insulation uye inodzivirira layer kugadzira yakanyanya kusimba, kushamwaridzana kwemuviri wemunhu neganda rekunze kwetambo hakuzove nengozi.

Cable yekuisa zvakare yakangwarira kwazvo, tambo inonyanya kuvigwa mune yakakosha cable mugero, cable row pipe, kana cable tunnel, pasi pekuchengetedzwa kwakanaka kwekuparadzaniswa uye kuchengetedzwa.

Kudzika kunonyanya kuderera hafu yemamita, uye yakakwirira yevoltage level, kudzika tambo inovigwa.

Uyezve, pachave netambo ichishanda zvakanaka kana tambo yemakaki sechiratidzo emamita mashoma gumi nemaviri pasi panovigwa tambo yekuyeuchidza vanhu nezvekuchengeteka..

Saka, tambo dzepasi pevhu kazhinji hadzikonzere njodzi kune vagari.
