1. umqondo wemigqa yokudlulisela (yokudlulisela).
Intambo yokudlulisa (yokudlulisa) ixhunywe endaweni yokuphehla amandla kanye nesiteshi esincane (ihhovisi) sokudluliswa kwezintambo zikagesi.
2. izinga likagesi lemigqa yokudlulisela
Ekhaya: 35kV, 66kV, 110kV, 220kV, 330kV, 500kV, 750kV, ± 80okV.1000kV.
Isifundazwe: 35kV, 110kV, 220kV, 500kV, ±8ookV
3. Ukuhlukaniswa kwezintambo zokudlulisela
(1) ngokuya ngohlobo lwamanje lokudlulisela: Imigqa yokudlulisa ye-AC, imigqa yokudlulisela ye-DC.
(2) ngokusho kwesakhiwo: imigqa yokudlulisa phezulu, izintambo zekhebula.
Ukwakhiwa kwezingxenye eziyinhloko zolayini wokudlulisa phezulu: umqhubi, ulayini wombani (okubhekiselwa kuwo njengolayini wombani)
Izinto zokufakwa, ama-insulators, imibhoshongo, izintambo nezisekelo, amadivaysi okumisa phansi.
Umbhoshongo womugqa ongaphezulu ngokuvamile usekelwe ezintweni zawo, ukusetshenziswa, inani le-conductor circuit, ifomu lesakhiwo nokunye.
4. Ukwahlukanisa
(1) Ngokwesigaba sezinto ezibonakalayo: izigxobo zikakhonkolo eziqinisiwe, izigxobo zensimbi, umbhoshongo wensimbi we-engeli, umbhoshongo wensimbi.
(2) Ngokusetshenziswa kwezigaba: umbhoshongo oqondile (oyisigxobo), umbhoshongo ongabambeki (isigxobo), umbhoshongo ohlukene (isigxobo), umugqa oqondile, umbhoshongo wekhona elincane (isigxobo). Umbhoshongo omncane osekhoneni (isigxobo), ngaphesheya kombhoshongo (wesigxobo).
(3) Ngokwenani lezifunda ezizohlukaniswa: isifunda esisodwa, isifunda esiphindwe kabili, izifunda ezintathu, izifunda ezine, izifunda eziningi.
(4) Ihlukaniswa ngokwesakhiwo: umbhoshongo othayi, umbhoshongo ozisekela wona, umbhoshongo wensimbi ozisekela wona.
5. Izinkinga zolayini bokudlulisa wesekethe eyodwa.
Ezindaweni ezithuthuke ngokwezomnotho nezinabantu abaningi, izinsiza zomhlaba ziyindlala kakhulu, ukwakhiwa kolayini owodwa kuphela.
Ukwakhiwa kwezintambo zokudlulisa isekethe eyodwa ngeke kusahlangabezana nesidingo sikagesi.
Imigqa ye-Multi-turn enombhoshongo ofanayo iyindlela ephumelelayo yokuthuthukisa umthamo wokudlulisela we-corridor yomugqa, ongakwazi ukwandisa umthamo wokudlulisela endaweni ngayinye yeyunithi yomugqa, kodwa futhi ukwandisa umthamo womugqa.
Indawo yeyunithi yomgwaqo yomthamo wokudlulisa, ukwandisa ukulethwa kwamandla, kodwa futhi yehlise izindleko zizonke.
EJalimane, uhulumeni ubeka ukuthi yonke imigqa emisha kufanele yakhiwe phezu kombhoshongo owodwa izikhathi ezingaphezu kwezimbili. Kulayini we-high-voltage ultra-high-voltage
Umgwaqo, wombhoshongo ofanayo izikhathi ezine emigqeni evamile, kuze kube izikhathi eziyisithupha. Kusukela ngo-1986, umbhoshongo ofanayo kanye nohlaka lomugqa ohlangene wokubuyisela okuningi ubude bungamamitha angu-2,000.
Kusukela ngo-1986, ubude bezintambo ezihlangene eziningi ezinombhoshongo ofanayo babungaba ngu-27,000km, futhi sekube neminyaka engaphezu kwengu-50 yokusebenza.
E-Japan, imigqa eminingi engu-110 kV nangaphezulu yizisekhethi ezine ezinombhoshongo ofanayo, kanti imigqa engu-500 kV yonke iyisekhethi eyodwa enombhoshongo ofanayo, ngaphandle kwemibili yokuqala.
Imigqa engu-500kV, ngaphandle kwemigqa emibili yesekethe eyodwa ezinsukwini zakuqala, yonke ingamasekhethi aphindwe kabili kumbhoshongo owodwa. Njengamanje, inani eliphezulu lezifunda embhoshongweni ofanayo eJapane ziyisishiyagalombili.
Eminyakeni yamuva, ngokwakhiwa okusheshayo kwamagridi kagesi, i-Guangdong nezinye izifunda ezinombhoshongo ofanayo wohlelo lokusebenza lwezifunda eziningi nazo zilinganiselwe futhi kancane kancane ziye zaba ubuchwepheshe obuvuthiwe.
