1. pfungwa yekufambisa (kutumira) mitsetse
Transmission (transmission) tambo yakabatana kune simba rekudyara uye substation (hofisi) yekufambiswa kwemagetsi magetsi tambo.
2. iyo voltage level yemitsara yekutumira
Mumba: 35kV, 66kV, 110kV, 220kV, 330kV, 500kV, 750kV, ± 80okV.1000kV.
Dunhu: 35kV,110kV,220kV,500kV,±8ookV
3. Kurongwa kwemitsara yekufambisa
(1) zvichienderana nemhando yekutumira ikozvino: AC transmission mitsara, DC mitsetse yekufambisa.
(2) maererano nechimiro: mitsara yekufambisa pamusoro, tambo dzetambo.
Kuumbwa kwezvikamu zvikuru zvemutsetse wekufambisa wepamusoro: conductor, mutsara wemheni (inonzi mutsara wemheni)
Fittings, insulators, shongwe, waya uye nheyo, pasi midziyo.
Iyo shongwe yemutsetse wepamusoro inowanzoenderana nezvayo, kushandiswa, nhamba ye conductor wedunhu, chimiro chechimiro uye zvichingodaro.
4. Kuronga
(1) Zvinoenderana nemhando yezvinhu: matanda ekongiri akasimbiswa, mapango esimbi, kona yesimbi shongwe, shongwe yesimbi.
(2) Maererano nekushandiswa kwechikamu: linear (pole) shongwe, tension-resistant (pole) shongwe, divergent (pole) shongwe, mutsara wakatwasuka, kona diki (pole) shongwe. Diki kona (pole) shongwe, mhiri (pole) shongwe.
(3) Zvichienderana nehuwandu hwemaseketi anofanirwa kuiswa mumapoka: dunhu rimwechete, dunhu rakapetwa kaviri, masekete matatu, masekete mana, akawanda maseketi.
(4) Yakarongedzerwa nechimiro chechimiro: tie-line tower, self-supporting tower, self-supporting steel tower.
5. Matambudziko e-single-circuit transmission lines.
Munzvimbo dzehupfumi dzakasimukira uye dzine vanhu vakawanda, zviwanikwa zvevhu zvakashomeka, kungovakwa kwetambo imwe chete yekufambisa.
Kuvakwa kwemitsara yekufambisa yedunhu rimwe chete haichakwanisi kusangana nezvinodiwa zvemagetsi.
Multi-turn mitsara ine shongwe imwechete inzira inobatsira yekuvandudza simba rekutapurira kwetambo corridor, iyo isingagoni kungowedzera simba rekutapurira pane imwe unit nzvimbo yemutsara, asiwo kuwedzera kukwanisa kwemutsara.
Road unit nzvimbo yekutapurirana simba, wedzera simba rekutakura, asi zvakare kuderedza mutengo wakazara.
KuGermany, hurumende inoti mitsetse mitsva yose inofanira kuvakwa pashongwe imwe chete kwekanopfuura kaviri. Mune high-voltage ultra-high-voltage line
Mugwagwa, weshongwe imwe chete kane kune yakajairika mitsetse, kusvika katanhatu. Kubva 1986, iyo shongwe imwechete uye furemu yakawanda-yekudzosa compact mutsara kureba ingangoita 2,000 metres.
Kubva muna 1986, hurefu hwese hwema-multi-turn compact mitsara ine shongwe imwechete yaive 27,000km, uye kwave nemakore anopfuura makumi mashanu echiitiko chekushanda.
MuJapan, mitsetse yakawanda ye110 kV uye kumusoro ine matunhu mana ane shongwe imwe chete, uye mitsara ye500 kV yose ine dunhu rimwe chete rine shongwe imwe chete, kunze kwemaviri ekutanga.
500kV mitsetse, kunze kwemitsetse miviri yedunhu rimwe chete mumazuva ekutanga, ese ari maviri maseketi pashongwe imwe chete. Parizvino, nhamba huru yematunhu pashongwe imwe chete muJapan isere.
Mumakore achangopfuura, nekukurumidzira kuvakwa kwemagidhi emagetsi, Guangdong nemamwe matunhu ane shongwe imwechete-yakawanda-yedunhu application iriwo zvishoma uye zvishoma nezvishoma yave tekinoroji yakakura.
Nguva yekutumira: May-23-2024
