Isiguquli sokuxhuma esivulekile se-delta yisigaba sesithathu, uhlelo lokuhlinzekwa kwesigaba esisodwa esisebenzisa amandla afanayo nhlangothi zombili. Ama-transformer axhunywe ngendlela yokuthi ahlinzekele ukushintshana kwamanje komunye nomunye ngaphandle kokuxhumana okuqondile phakathi kwawo - lokhu kubangela ukuthi kube khona umehluko we-120 degrees kolunye uhlangothi lwelinye icala nozakwabo (120 °).
Luyini ukuxhumana kwe-3-phase delta?
Ukuxhumeka kwesigaba se-delta esinezigaba ezi-3 uhlobo lohlelo lwamandla kagesi oluxuba izigaba ezintathu. Lezi zinhlelo zivame ukusetshenziselwa ukusabalalisa ugesi omningi emabangeni amade ezindaweni eziphakeme kakhulu, njengakwizintambo zokudlulisa ezingama-400 kV kanye nama-450kv.
I-Delta (Δ) noma i-Mesh Connection ixhuma ukuphela okuqediwe kwesiginali sokuqala esijiyayo ngesinye isigaba isinikeze isifunda esivaliwe esivumela ukusatshalaliswa okulula emabangeni amade ngenxa yamandla amakhulu we-voltage afinyelela ku-750kv!
Kusetshenziswa kuphi ukuxhumana okuvulekile kweDelta?
Uhlelo lokuxhuma oluvulekile lwe-delta lubizwa nangokuthi uhlelo lwe-VV. Lolu hlobo lwentambo yokudlulisa amandla, edlulisa ugesi kusuka kumasayithi akhiqizwayo kuya kumakhasimende ngokusebenzisa imigqa emithathu ye-AC esikhundleni sezimbili njengokucushwa kwe-delta evaliwe (noma Y), ingasetshenziswa kuphela ngesikhathi esiphuthumayo ngoba ukusebenza kwayo kuhluka kakhulu uma kuqhathaniswa ngalokhu okutholakala ekulungiselelweni okujwayelekile okufana nalokho okubonakala ezinhlelweni ezivaliwe ze-delta nasekushintsheni kokudluliswa kwephoyinti elilodwa.
Kungani i-Open Delta Connection isetshenziswa ku-PT?
Lapho kwenzeka amaphutha omhlaba, kubizwa ngokuthi yi-delta ephukile. Lolu hlobo oluthile lokuthola iphutha lunemigqa emibili esuka ocingweni olulodwa iye kolunye e-engeli elinganisa cishe ama-degree ayi-120 komunye nomunye bese bobabili bagcina ku-transformer efanayo. Kepha okwenza lokhu kulungiswa kwehluke kunesistimu yakho ejwayelekile enezintambo ezintathu izintambo zayo ezibhekwayo ngeso lesigaba samandla kagesi ezingathola noma yiziphi izinguquko maqondana nesikhathi noma ukugeleza kwamanje kunoma yimuphi umugqa ohlangothini lwendawo evulekile lapho bahlangana khona futhi kulinganisa ukuphazamiseka kokulayisha phakathi kwezigaba ngokuzibambezela kuze kube yilapho zonke izithiyo sezilinganisiwe (ukubeka amandla amaningi kunoma yimuphi umugqa okudingayo).
Futhi funda: ungalola kanjani i-chainsaw nge-grinder
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
