1. Iyini ikhebula lamandla le-High Voltage?
Ikhebula Lamandla Elinamandla Eliphezulu liwumkhiqizo obalulekile osetshenziswa ezinhlelweni zokudlulisa nokusabalalisa amandla kagesi aphakathi naphezulu ukuze kudluliselwe futhi kusatshalaliswe amandla kagesi. Izilinganiso ezivamile zama-voltage zifaka phakathi i-6kV, i-10kV, i-35kV, i-110kV nangaphezulu. Lisetshenziswa kabanzi kumagridi kagesi asemadolobheni, ezokuthutha ngesitimela, ukukhiqizwa kwamandla avuselelekayo kanye namaphrojekthi engqalasizinda amakhulu.
Uma kuqhathaniswa nezintambo zendabuko eziphezulu, izintambo zikagesi ezinamandla aphezulu zinikeza izinzuzo ezifana nokungabi bikho komhlaba, ukuphepha okuphezulu kanye nokuzivumelanisa nezimo okuqinile kwemvelo, okwenza zifaneleke kakhulu ezimweni zokufakwa komhlaba zasemadolobheni. Ngokuthuthukiswa kwegridi kanye nokuthuthukiswa kwamandla avuselelekayo, izidingo eziphakeme zibekwa ekuthembekeni kwesikhathi eside kanye nokusebenza kwezinto ezibonakalayo zezintambo.
2. Isakhiwo kanye nezinto ezibalulekile zekhebula lamandla aphezulu
Izintambo zamandla ezinamandla aphezulu ngokuvamile ziqukethe umqhubi, uhlelo lokuvikela, isakhiwo sokuvikela amanzi, ungqimba lwezivikelo kanye negobolondo langaphandle. Ukufaniswa kokusebenza kwezinto ezingqimbeni ngayinye kuthinta ngqo ukuphepha nokuphila kwenkonzo yekhebula.
Uhlelo Lokuqhuba Nokufaka Ukushisa
Umqhubi ngokuvamile wenziwe ngezinto zethusi noma i-aluminium ezihlanzekile kakhulu. Ukuze kuncishiswe umphumela wesikhumba ekudlulisweni kwe-AC, izintambo ezinkulu ezinqamula izigaba zivame ukusebenzisa izakhiwo zomqhubi ezivalekile noma ezihlukaniswe ukuze kuthuthukiswe ukusatshalaliswa kwamanje nokunciphisa ukulahleka.
Izinto eziyinhloko zesistimu yokushisa ukushisa yileziI-XLPE(I-Cross-linked Polyethylene Insulation Compound), enekhono elihle kakhulu lokuvikela ugesi, ukumelana okuhle nokuguga kokushisa kanye nokushisa okuphezulu okuqhubekayo, okwenza isetshenziswe kabanzi kumakhebula kagesi aphezulu kanye ne-voltage ephezulu kakhulu.
I-Semi-Conductive Shielding Compound ivame ukulungiselelwa ngaphandle komqhubi ukuze ihlanganise ukusatshalaliswa kwensimu kagesi, inciphise ukugcwala kwensimu kagesi futhi inciphise ingozi yokukhishwa kwengxenye, ngaleyo ndlela ithuthukise ukuzinza kwesikhathi eside kwesistimu yokushisa.
Ukuvikela, Ukuvimba Amanzi kanye Nesakhiwo Sezivikelo
Isendlalelo sokuvikela sensimbi sivame ukusebenzisa iteyipu yethusi noma isakhiwo sentambo yethusi ukuze sihlanganise ukusatshalaliswa kwensimu kagesi futhi sinikeze indlela ethembekile yokufaka isisekelo. Ukufana kobukhulu, isimo sobuso kanye nokucutshungulwa kweteyipu yethusi kuthinta ngqo ikhwalithi yokwakheka kwesendlalelo sokuvikela kanye nokuqina kokukhiqiza.
Ukuze kuthuthukiswe ukuthembeka kwesikhathi eside kwezintambo ezindaweni zokungcwaba ngqo noma ezinomswakama ophezulu,Itheyiphu Yokuvimba Amanzikanye ne-Water Blocking Yarn ngokuvamile isetshenziselwa ukuvimbela ukufuduka komswakama okuhlala isikhathi eside ngaphakathi kwekhebula.
Ezindaweni zokusetshenziswa ezinokucindezeleka okuphezulu komshini, izintambo zamandla ezinamandla aphezulu zivame ukunikezwa ungqimba lokuvikela ukuze kuthuthukiswe ukucindezelwa kanye nokumelana nomthelela. Izinto ezivamile zifaka i-Galvanised Steel Tape kanye ne-Galvanised Steel Wire Strand. Ukuqina kwazo okulinganayo kanye nokucutshungulwa kwazo kuthinta ukusebenza kwe-armour okulandelayo kanye nokuqhubeka kokukhiqiza.
Umgoqo Wangaphandle
Igobolondo langaphandle lisetshenziselwa ukuvikela ikhebula ngaphandle, ikakhulukazi lihlinzeka ngokumelana nomswakama, ukumelana nokugqwala kanye nokumelana nokucindezeleka kwemvelo. Izinto ezivamile zifaka phakathi i-PVC Compound, i-PE Sheath Material kanye ne-LSZH (Low Smoke Zero Halogen Sheath Material).
Phakathi kwalokhu, izinto ze-LSZH zisetshenziswa kakhulu kwezokuthutha ngesitimela, izikhungo zedatha kanye nezakhiwo zomphakathi ezinezidingo eziphezulu zokuphepha emlilweni ngenxa yentuthu yayo ephansi, i-halogen engenayo kanye nezici zayo ezivimbela ilangabi.
Njengomhlinzeki wezinto zekhebula, i-ONE WORLD ingahlinzeka ngezinto ezahlukahlukene ezihlobene nezintambo zikagesi eziphezulu, okuhlanganisa i-XLPE insulation compound, i-semi-conductive shielding compound, i-copper tape, i-water blocking tape, i-galvanized steel tape, i-galvanized steel wire strand kanye ne-sheathing compounds.
3. Kungani Izinto Zekhebula Zibaluleke Kangaka?
Ukusebenza kwezintambo zikagesi ezinamandla aphezulu akuxhomekile nje kuphela ekwakhiweni kwesakhiwo kodwa futhi nasekuhambisaneni kwezinto ezahlukene. Kusukela ku-XLPE insulation compound kuya ku-copper tape shielding layer, bese kuba yi-water blocking tape, i-galvanized steel tape kanye nezinto zokubopha, into ngayinye ithinta ukusebenza kwe-electric insulation, ikhono lokuvikela imishini kanye nokuzinza kokusebenza kwesikhathi eside kwentambo.
Ngesikhathi esifanayo, ukuzinza kwenqubo yezinto zokwakha ngesikhathi sokugoqa okude, ukukhulula, ukuvikela kanye nokukhipha kuthinta ngqo ukusebenza kahle kokukhiqiza kanye nokungaguquguquki komkhiqizo. Ngakho-ke, ukucutshungulwa kwezinto zokwakha ezindaweni zokukhiqiza zangempela kuya ngokuya kubaluleka ngabakhiqizi bekhebula.
4. Izitayela Zokuthuthukiswa Kwekhebula Lamandla Eliphezulu
Esikhathini esizayo, izintambo zikagesi ezinamandla aphezulu zizoqhubeka nokuthuthuka zibe nokusebenza okuphezulu, ubungane bemvelo kanye nobuhlakani. Ama-compounds okushisa e-XLPE asebenza kahle kakhulu, ama-compounds e-LSZH sheathing anobungani nemvelo, kanye nezinto zokuvimba amanzi ezizinzile kakhulu zizohlangabezana nezidingo zamandla avuselelekayo, ukuthuthukiswa kwegridi kanye nezicelo eziyinkimbinkimbi zemvelo.
Ngokuthuthukiswa kwamagridi ahlakaniphile, ukuqapha isimo sekhebula kanye nobuchwepheshe bokuxwayisa ngamaphutha kuzosetshenziswa kancane kancane. Izinto ezibalulekile zekhebula ezifaka phakathi i-copper tape, i-water blocking tape, i-galvanized steel tape kanye ne-XLPE insulation compound zizoqhubeka nokuthuthukisa ukuphepha, ukuthembeka kanye nokuzinza kwenqubo yezintambo zamandla ezinamandla aphezulu.
