Ungakulawula kanjani ukugqwala kukagesi kwekhebula le-ADSS optical?
Ngokwazi kwethu, wonke amaphutha okugqwala kagesi enzeka endaweni yobude obusebenzayo, ngakho-ke ububanzi okufanele bulawuleke bugxiliswe kuzoni yobude obusebenzayo.
1. isilawuli esimile:
Ngaphansi kwezimo ezimile, kukhebula le-AT sheathed ADSS optical esebenza ohlelweni lwe-220KV, amandla wendawo wephoyinti layo lokulenga kufanele alawulwe angabi ngaphezu kuka-20KV (imigqa ye-co-frame eyi-double-circuit kanye ne-multi-circuit co-frame kufanele ibe phansi);esebenza ngamasistimu angu-110KV nangaphansi Ngentambo yokubona ye-ADSS enesheyethi ye-PE, amandla wendawo wendawo yokulenga kufanele alawulwe ukuze abe ngaphansi kuka-8KV.Idizayini engaba khona yendawo yendawo yokulenga emile kufanele icabangele:
(1) I-voltage yesistimu nokuhlelwa kwesigaba (izihibe ezimbili nezihibe eziningi zibaluleke kakhulu).
(2) Ukuma kwesigxobo nombhoshongo (kuhlanganise nekhanda lombhoshongo kanye nobude begama).
(3) Ubude bentambo yesivikelo (ubude buyahlukahluka kuye ngezinga lokungcola).
(4) Ububanzi bekhondakta/intambo ephansi kanye nokuhlukaniswa kwekhondakta.
(5) Ibanga lokuphepha phakathi kocingo nomhlabathi kanye nezinto eziphambanayo.
6 inkulu kunekhebula yokubona I-MAT ingu-40% RTS).
(7) Ama-Jumpers (izigxobo ezicindezelayo) kanye nemizimba ephansi (njengezintambo zikasimende) kufanele zicutshungulwe futhi kubhekwe umthelela wazo.
2.ukulawula okunamandla:
Ngaphansi kwezimo eziguquguqukayo, amandla esikhala sekhebula le-AT sheathed ADSS optical esebenza ohlelweni lwe-220KV kufanele lilawulwe lingabi ngaphezu kwama-25KV;ikhebula le-PE elakhiwe nge-ADSS optical cable esebenza ohlelweni lwe-110KV nangaphansi, amandla esikhala sephoyinti elilengayo kufanele kube Lawula lingabi ngaphezu kuka-12KV.Izimo eziguqukayo kufanele okungenani zicabangele:
(1) I-voltage yesistimu i-voltage yegama, futhi ngaphansi kwezimo ezithile kuzoba nephutha lika-+/-(10～15)%, futhi ukubekezelela okuhle kuzothathwa;
(2) Intambo yezinto ezifakwayo (ikakhulukazi intambo elengayo) nokushwibeka komoya kwentambo yokubona;
(3) Amathuba okuguqulwa kwesigaba sokuqala;
(4) Amathuba okusebenza kwesiyingi esisodwa sohlelo lwesiyingi esikabili;
(5) Isimo sangempela sokudluliswa kokungcola esifundeni;
(6) Kungase kube nemigqa emisha ye-crossover nezinto;
(7) Isimo sezinhlelo zokwakhiwa nokuthuthukiswa kukamasipala kulo mzila (singaphakamisa isisekelo);
(8) Ezinye izimo ezizothinta intambo yokubona.
Ikhumbuza ukuthi lezi kufanele zinakwe ekwakhiweni kwezintambo zentambo ye-ADSS optical cable.
(1) Ukugqwala kukagesi komgodla wekhebula le-ADSS optical ngaphansi kwe-tension ngesikhathi sokusebenza kubangelwa ukuvuza kwamanje okungaphansi okungaba ngu-0.5-5mA kanye ne-arc yebhande elomile elibangelwa amandla esikhala (noma amandla enkundla kagesi) ngokusebenzisa i-capacitive coupling.Uma kuthathwa izinyathelo zokulawula ukuvuza komhlaba okungaphansi kwe-0.3mA futhi i-arc eqhubekayo ingakhiwa, ukugqwala kagesi kwe-sheath ngeke kwenzeke ngokusemthethweni.Indlela engokoqobo nesebenza ngempumelelo kusewukulawula ukushuba kwesimo namandla wekhebula obonakalayo.
(2) Idizayini engaba khona yesikhala esimile ye-AT noma i-PE sheathed ADSS Optical cable akufanele ibe ngaphezu kuka-20KV noma 8KV, ngokulandelana, futhi akufanele ibe ngaphezu kuka-25KV noma 12KV ngaphansi kwezimo ezimbi kakhulu zokuguquguquka.Ikhebula le-fiber optic lingasebenza ngokuphepha.
(3) Amandla esikhala esimile ama-20KV (ikakhulukazi isistimu ye-220KV) noma i-8KV (ikakhulukazi isistimu ye-110KV).Ihadiwe yokuhlukanisa isiswebhu sokudlidliza ohlelweni ayikho ngaphansi kuka-(1～3)m noma u-0.5m, ngokulandelanayo, ukuze kuthuthukiswe i-ADSS Esinye sezinyathelo ezisebenzayo zokugqwala kukagesi kwezintambo ezibonakalayo.Ngesikhathi esifanayo, ukulimala kokudlidliza kwekhebuli yokubona ye-ADSS nezinye izindlela zokunqanda ukudlidliza (njengesando sokudlidliza esisebenzayo) kufanele kufundwe.
(4) Indawo yokufaka yekhebula yokubona (evame ukubizwa ngokuthi iphoyinti lokulenga) ayikwazi ukunqunywa ngokwamandla ngokusekelwe ezingeni le-voltage yesistimu kanye/noma ibanga ukusuka kumkhondatha wesigaba.Ikhono lesikhala lephoyinti lokulenga kufanele libalwe ngokuvumelana nezimo ezithile zohlobo ngalunye lombhoshongo.
(5) Nakuba kuye kwaba nokuhluleka kagesi ukugqwala okuvamisile kwezintambo ezibonakalayo ze-ADSS eminyakeni yamuva, inani elikhulu lezinqubo liye lafakazela ukuthi izintambo ezibonakalayo ze-ADSS zingaqhubeka zithuthukiswa futhi zisetshenziswe ezinhlelweni ze-110KV;Izintambo ezibonakalayo ze-ADSS ezisetshenziswa ezinhlelweni ze-220KV zicabangela ngokugcwele izimo zokusebenza ezimile neziguquguqukayo.Kamuva, ungaqhubeka nokuphromotha uhlelo lokusebenza.
(6) Esakhiweni sokuqinisekisa ikhwalithi yekhebula le-ADSS optical, ukulinganisa umklamo wobunjiniyela, izimo zokwakha nezimo zokusebenza, kanye nokugqwala kukagesi wentambo yokubona ye-ADSS kungalawulwa.Kunconywa ukwakha nokusebenzisa izinkambiso/izinqubo ezihambisanayo ngokushesha okukhulu.
