Emikhakheni yezohwebo nezimboni, amasistimu okugcina amandla abe yisisekelo sokuphakelwa kukagesi nokulawulwa kwesidingo kanye nokuhlanganiswa kwamandla ahlanzekile. Abagcini nje ngokulawula ngempumelelo ukuguquguquka kwegridi futhi baqinisekise ukuhlinzekwa kwamandla okuzinzile, kodwa futhi bakhuthaze ukwenziwa kahle kwesakhiwo samandla. Intambo yaphansi ingasethula izingozi ezingaba khona zokuphepha ezifana nogesi omile kanye nokuvuza kwamanje okungase kukhiqizwe isistimu emhlabeni, ivikele izinto zokusebenza nabasebenzi ekushayweni kukagesi nokunye ukulimala, futhi iqinisekise ukusebenza okuphephile nokuzinzile kwendawo yokugcina amandla. uhlelo.
Ukuhlaziywa kwamandla okuphethe njengamanje emakhabetheni okugcina amandla ezimboni nawezohwebo, amandla esistimu ngokuvamile afinyelela ku-100KW, uhla lwamandla kagesi olukalwe luka-840V kuya ku-1100V. lesi sangemuva, umthamo wokugcwala kwentambo yaphansi ibe yinto ecatshangelwayo yokukhetha. Ngokuqondile, ku-840 V, umthamo ogcwele wamanje ungaba ngu-119 A, kuyilapho ku-1100 V, umthamo ogcwele wamanje ungaba ngu-91 A. Ngokusekelwe kulokhu, kunconywa ukusebenzisa abaqhubi bethusi be-3 AWG (26.7 mm2) nangaphezulu ukuze qinisekisa ukuthi izintambo zinamandla anele okuthwala okwamanje, ukuze uhlelo lukwazi ukugcina ukuphepha nokuzinza futhi luvimbele izingozi zikagesi ukuthi zenzeke, ngisho noma kwenzeka umthwalo omkhulu noma imisinga yephutha engazelelwe.
Ukuhlola ukuguquguquka kwemvelo Njengoba kunikezwe ukuthi izinhlelo zokugcina amandla ezimbonini nezohwebo zisetshenziswa kakhulu ezindaweni ezingaphandle, izintambo zidinga ukumelana kahle nezinga lokushisa kanye nokumelana nesimo sezulu ukuze zibhekane nezinga lokushisa eliphezulu, umswakama ophezulu kanye nezinye izindawo ezingase zihlangabezane nazo ohlelweni lokugcina amandla. Kunconywa ukuthi izintambo ezine-XLPE noma i-PVC insulation kufanele zibe nezinga lokushisa elilinganiselwe elicishe libe ngu-105°C ukuze kuqinisekiswe ukuthi ngisho nangaphansi kwezimo zokukhuphuka kwezinga lokushisa ngesikhathi sokusebenza kwesistimu, izintambo zisengakwazi ukulondoloza ukusebenza kwazo kukagesi namandla emishini ukuze kugwenywe ukwehluleka kukagesi okubangelwa. ngezici zemvelo.
Umkhuba wokukhetha ikhebula Ngaphezu kwalokho, ukusebenza kahle okuphezulu kanye nokugcinwa okuphansi sekuphenduke isiqondiso sokuthuthukiswa kokugcinwa kwamandla ezimbonini nezohwebo, ukuzinza kwekhebula kungaba ukucatshangelwa okubalulekile ekukhetheni izintambo ezisezingeni eliphezulu kunganciphisa imvamisa yokushintshwa, ukunciphisa ukusebenza. kanye nezindleko zokunakekela, ukuthuthukisa ukusebenza kahle jikelele kohlelo. Ngakho-ke, esigabeni sokukhetha, kufanele kubekwe kuqala emikhiqizweni eye yahlolwa kanzima kanye nokuqinisekiswa kwemakethe ukuze kusekelwe ukusebenza okuzinzile kwesikhathi eside kohlelo.
Kusukela ngo-2009,I-Danyang Winpower Wire & Cable Mfg Co., Ltd. ibilima emkhakheni wezintambo zikagesi neze-elekthronikhi iminyaka ecishe ibe ngu-15, iqongelela ulwazi lwemboni ecebile kanye nokusha kwezobuchwepheshe. Sigxila ekuletheni izixazululo zezintambo ezisezingeni eliphezulu nezizungeza zonke zezinhlelo zokugcina amandla emakethe, umkhiqizo ngamunye uqinisekiswe ngokuqinile yiziphathimandla zase-Europe nezaseMelika, futhi ulungele amasistimu kagesi okugcina amandla angu-600V kuya ku-1500V, kungakhathaliseki ukuthi umkhulu- Isiteshi samandla okugcina amandla esikalini noma isistimu encane esabalalisiwe, ungathola izixazululo ezifanele kakhulu zokufaka izintambo eziseceleni kwe-DC.
Iziphakamiso zokukhetha izintambo eziphansi
