Isiguquli soqhagamshelo oluvulekileyo lwedatha sisigaba esithathu, inkqubo yokubonelela yenqanaba elinye esebenzisa amandla afanayo kumacala omabini. Abaguquli banxibelelene ngendlela yokuba babonelele ngoku ngokutshintshanayo omnye komnye kungabikho nxibelelo ngqo phakathi kwabo - oku kubangela ukuba kubekho iidigri ezili-120 zomahluko kwelinye icala lesiphelo kunye nogxa walo (120 °).
Luyintoni uqhagamshelo lwesigaba esithathu sedela?
Unxibelelwano lwamanqanaba amathathu e-delta luhlobo lwenkqubo yamandla ombane exuba izigaba ezithathu. Ezi nkqubo zihlala zisetyenziselwa ukuhambisa umbane omkhulu kwimigama emide kwiindawo eziphezulu, njengakwimigca yokuhambisa eyi-3 kV kunye ne-400kv.
I-Delta (Δ) okanye i-Mesh Connection idibanisa i-terminal egqityiweyo yesiphelo sendlela yokuqala enesinye isigaba ukuyinika isekethe evaliweyo evumela ukuhanjiswa ngokulula kwimigama emide ngenxa yamandla ombane aphezulu ukuya kuthi ga kwi-750kv!
Iphi indawo evulekileyo yoQhagamshelo lweDelta?
Inkqubo yonxibelelwano evulekileyo ebizwa ngokuba yinkqubo yeVV. Olu hlobo lwentambo yokuhambisa umbane, ehambisa umbane ukusuka kwiziza zokuvelisa ukuya kubathengi ngokusetyenziswa kwemigca emithathu yesigaba se-AC endaweni yesibini njengakwisakhelo se-delta esivaliweyo (okanye Y), inokusetyenziswa kuphela ngexesha likaxakeka kuba ukusebenza kwayo kuyahluka kakhulu xa kuthelekiswa kunye noko kufunyenwe kuqulunqo olusemgangathweni ngakumbi njengalolo lubonwa kwiinkqubo ezivaliweyo ze-delta kunye nokutshintsha kokutshintsha kwenqaku elinye.
Kutheni i-Open Delta Connection isetyenziswa kwi-PT?
Xa umhlaba wenze iimpazamo, kubizwa ngokuba yi-delta eyaphukileyo. Olu hlobo oluthile lokufumanisa isiphoso lunemigca emibini ukusuka kolunye ucingo luye kwenye kwi-engile elinganisa malunga ne-120 degrees komnye komnye zize zombini ziphele kwisiguquli esinye. Kodwa yintoni eyenza oku kuqulunqwa kwahlukile kunendlela oqhele ngayo yocingo-ntathu imilinganiselo yayo ibekwe esweni ngesishwankathelo sevolthi yesigaba esinokubona naluphi na utshintsho ngokubhekisele kwixesha okanye ukuhamba ngoku nangaliphi na icala nakweliphi na icala lendawo evulekileyo abadibana kuyo kunye Ukulinganisela ukuphazamiseka kwemithwalo phakathi kwezigaba ngokuzilibazisa kude kube emva kokuba zonke iimpazamo zilungelelanisiwe (ukubeka amandla ngakumbi kuwo nawuphi na umgca oyifunayo).
