Ukwengeza izintambo ze-ADSS kulayini we-110kV okade usebenza, inkinga enkulu ukuthi ekwakhiweni kwasekuqaleni kombhoshongo, akukho ukucatshangelwa nhlobo ukuvumela ukwengezwa kwanoma yiziphi izinto ezingaphandle komklamo, futhi ngeke kushiye isikhala esanele. yekhebuli ye-ADSS.Okubizwa ngokuthi isikhala akubandakanyi kuphela Indawo yokufaka yekhebula le-optical futhi ihlanganisa amandla omshini wombhoshongo nezinye izici ezihlobene.Ngamanye amazwi, izintambo ezibonakalayo ze-ADSS zingakwazi ukuzivumelanisa kuphela nemibhoshongo yasekuqaleni ngangokunokwenzeka.
1. Umbhoshongo othwala imithwalo
Lolu hlobo lwezigxobo lungamelana nokushuba okujwayelekile kwe-longitudinal komugqa kanye nokushuba komugqa ophukile uma kwenzeka ingozi.Ngokusho kwenhloso, ingabuye ihlukaniswe ibe imibhoshongo efana ne-tension, ikona, i-terminal, kanye negatsha.Ngokuvamile, imigqa yekhebula yokubona ye-ADSS ifakelwe izinto ezingamelana nobunzima (okubizwa nangokuthi "i-static end") kule mibhoshongo.Umbhoshongo we-pole othwala umthwalo uyisisekelo esibalulekile sokuma kokusabalalisa ikhebula le-optical kanye namajoyinti.Umbhoshongo wesigxobo esithwala umthwalo wekhebula le-fiber optical eyengeziwe kufanele uhlolwe amandla ukuze kuqinisekiswe ukuthi ukushuba okwengeziwe kwentambo ye-fiber optical kusaphephile embhoshongweni ngaphansi kwezimo zezulu ezimbi kakhulu.
2. Isigxobo esiqondile
Leli inani elikhulu lezigxobo emugqeni wokudlulisela.Isetshenziswa engxenyeni eqondile yomugqa ukusekela ukuma okuqondile (okufana namandla adonsela phansi) kanye nemithwalo evundlile (njengomthwalo womoya) womugqa.Ngokwenhloso, ingabuye ihlukaniswe ibe imibhoshongo enjengamakhona, ama-transpositions, nama-spans.
Ikhebula le-ADSSimigqa ngokuvamile ayisetshenziswa njengamajoyinti ekhebula optical ezigxotsheni eziqondile nemibhoshongo.Eqinisweni, ukufakwa okuqondile (noma "okulenga") kuyasetshenziswa.Ngaphansi kwezimo ezikhethekile, uma kudingekile ukuxhuma umbhoshongo oqondile, ukufakwa okuklanywe ngokukhethekile kufanele kusetshenziswe.
3. Uhlobo lombhoshongo
Uhlobo lombhoshongo luhlobene nezici ezifana nezinga le-voltage yolayini wokudlulisa, inani lamaluphu esekethe kanye nesakhiwo sikakhondatha, izimo zezulu, izimo zokuma kwezwe kanye nezinye izici.Kunezinhlobo eziningi zezigxobo nemibhoshongo ezweni lakithi futhi ziyinkimbinkimbi kakhulu.Ikhebula le-Optical kanye nohlobo lombhoshongo kuhlobene ngokuqondile nokukhethwa kwamaphoyinti okulenga futhi kuthinta ngqo impilo yesevisi.Umqondo wokuthi ikhebula le-ADSS lingafakwa ebangeni elithile ukusuka ocingweni akulungile, okungenani hhayi ngokuqinile.
Umzimba wombhoshongo uzonquma ubude bokufakwa kwentambo yokubona, futhi kufanele uhlangabezane nebanga eliphephile phakathi kwendawo ephansi kakhulu yekhebula le-optical sag kanye nomhlabathi noma izakhiwo ngaphansi kwezimo zezulu ezimbi kakhulu.Inhloko yombhoshongo izonquma indawo yokulenga yekhebula le-optical, lapho amandla kagesi kufanele abe mancane kakhulu noma amancane, futhi ahlangabezane nezidingo zezinga lokulwa nokulandelela lomgodla wangaphandle wekhebula le-optical.
Ukusebenza kwe-aerodynamic kwekhebula le-ADSS kuhlobene kakhulu nokusebenza komshini kwekhebula le-ADSS optical, izimo zombhoshongo nezimo zezulu.Izakhiwo zemishini yezintambo ze-ADSS zihlanganisa ububanzi bekhebula, isisindo sekhebula, amandla aqinile, i-elastic modulus, njll.;izigxobo nemibhoshongo ibhekisela kakhulu esibayeni, i-sag yokufaka, njll., futhi izimo zezulu zibhekisela esivinini somoya nokushuba kweqhwa, okungalingana nekhebula le-optical Umthwalo womoya nomthwalo we-icing ukuze umelane.
Ikhebula le-ADSS limiswe endaweni eqinile yenkambu kagesi yolayini we-voltage ephezulu.Amandla akhiqizwa i-coupling capacitor phakathi kwekhebula le-ADSS optical kanye nolayini wesigaba se-voltage ephezulu naphakathi kwesistimu yokubona ye-ADSS nomhlaba akhiqiza amandla amanje ebusweni bekhebula le-optical elimanzi.Lapho ingaphezulu lekhebula le-optical liyomile futhi limanzi kancane Ngalesi sikhathi, i-arc izokwenzeka endaweni eyomile, futhi ukushisa okubangelwa i-arc kuzosusa i-sheath yangaphandle yendawo yokukhanya ye-ADSS.Ukuze uvimbele ukwenzeka kwalesi senzakalo esingenhla, izinga lamazwe ngamazwe lekhebula le-optical le-ADSS lidinga ukuthi ikhebuli yokubona ingasebenza ngokujwayelekile kumandla enkambu angu-12kV/m.Uma amandla enkambu kagesi engaphezulu kuka-12kV/m, izintambo ze-ADSS ezinamashethi avimbela ukugqwala kufanele kukhethwe.
