Xa iigridi zombane zivuthelana nombane, umqolo ongabonakaliyo wokuthembeka kwazo uxhomekeke kunxibelelwano lwe-fiber optic—ngena kwintambo ye-ADSS (All-Dielectric Self-Supporting). Njengenxalenye ebalulekileyo yezixhobo zanamhlanje.iinethiwekhi ze-fiber optic, I-ADSS ichaza kwakhona ukusebenza kakuhle ngeenzuzo ezitshintsha umdlalo: ifakela ngaphandle kokucima umbane, inciphisa ixesha lokusebenza; imelana nemijikelo yobushushu obugqithisileyo ukuze ilwe nokwaluphala; iqhayisa ngoyilo olukhaphukhaphu olunciphisa imithwalo yomkhenkce/yomoya kwiinqaba; kwaye ifikelela kubude obungaphezulu kwe-1000m, ilungelelanisa neendawo ezintsonkothileyo. La mandla ayenze yaba lilitye lesiseko kubaqhubi benethiwekhi yefayibha njengeWeihai Power Supply Company, eyasungulaI-ADSSiintambo zefayibha zangaphandle kwiitowuru ezikhoyo ze-220kV—de kube yingxaki yokubola kwe-electrocorrosion okuiteknoloji ye-fiber optic.
Ingozi Engacacanga Yokuqhagamshelwa Kwe-Fiber Optic
I-Electrocorrosion ijolise kwiintambo zefayibha ze-ADSS kwiindawo zokumiswa kufutshane nee-conductors ze-voltage ephezulu. Imiphezulu yeentambo ze-fiber optic ezingcolileyo kwiindawo ezifumileyo yenza iileya eziqhuba umbane, nto leyo ebangela ukuvuza kwemisinga. Njengoko imisinga ifudumeza i-optical fiberintambo, "iibhendi ezomileyo" zibangela ii-arcs (>500℃), zinyibilikisa isheath kwaye ziveze ii-fiber optic cores—zibeka emngciphekweni ukuthembeka konxibelelwano lwegridi.
Ubunjineli buyisisombululo sehlabathi: i-FD-X90 Nano-Coating
Ukujongana nale ntointambo ye-fiber opticubuthathaka, iWeihai isebenzisana nomsunguli wezixhobo ze-fiber opticI-Oyi International Ltd.Iqela labo elidibeneyo le-R&D lenze i-FD-X90 Special Inorganic Nano-Coating, linikezela ngokhuseleko oluneziteya ezininzi:
Ukuzicoca ngamanzi nokuzigcina ukhuselekile– Ithintela ukwakheka kokungcola okuqhubayo kwiindawo zekhebula ze-optical.
Ukumelana ne-Oxidation– Ithintela ukwakheka kwebhendi eyomileyo, ibaluleke kakhulu kwixesha elide leentambo zefayibha zangaphandle.
Ukufakwa kobushushu obuphezulu– Inciphisa ukuvuza kwamanzi ngaphantsi kwemida ye-arc.
Ukumelana nobushushu obugqithisileyo(>1000℃) – Ikhusela ii-cores zokukhanya ze-fiber optic ekonakalisweni yi-arcing.
Ukuqinisekiswa kwiNgxaki: Uvavanyo lweBlizzard Field
Ngowama-2005, uWeihai wafaka iintambo ze-ADSS ze-fiber drop ze-FD-X90 kwiitowers ezingama-400 kwimigca ye-220kV.
Xa kwabakho isiphepho semvula esibalulekileyo:
Iindawo zefayibha ezingagqunywanga zifumene ukugqwala okukhulu kwe-electrocorrosion. Ukufakelwa kweentambo ze-fiber optic ezigqunywe yi-FD-X90 kuhlala kuhleli. Ukuhlolwa emva kwesiphepho ngo-2007 kuqinisekisile ukuba akukho ukugqwala—okungqina indima yayo kwizisombululo zokunxibelelana kwe-fiber optic ezihlala ziqinile.
Ukuchaza ngokutsha ikamva le-Optical FiberIinethiwekhi
Namhlanje, iintlobo zeentambo ze-ADSS fiber optic eziqiniswe nge-FD-X90 zixhasa iigridi ezikrelekrele zehlabathi. Olu manyano lugqitha ukhuseleko lweentambo: luvumela ukuba zingaphazanyiswa. i-optical fiberintambo kuthungelwano, ukuqinisekisa uqhagamshelo lwe-fiber optic kwiziseko ezibalulekileyo. Ukufikelela kwe-Oyi kwihlabathi liphela (amazwe ali-143, abathengi abangama-268) kubeka i-FD-X90 njengokhuseleko oluqhelekileyo lokufakelwa kweentambo ze-fiber optic—ukuphakamisa ukuqina kwegridi ngokusebenzisa ubuchwepheshe obuphambili be-fiber optic.
