Uma sikhuluma ngokuzifaka emoyeni okuzisekelayo, esinye sezicelo ezivame kakhulu zokudluliswa kwebanga elide ukufakwa kwezintambo ze-fiber optic emibhoshongweni enamandla amakhulu.
Izakhiwo zamanje zamandla kagesi aphezulu zithumela uhlobo lokufakwa olukhangayo kakhulu ngoba zinciphisa ukutshalwa kwezimali kwingqalasizinda edingekayo ukuze kwakhiwe izixhumanisi ezintsha ze-fiber optic, lezi esezakhelwe ngaphakathi.Kodwa imigqa emibhoshongweni enamandla amakhulu ngokuvamile iveza izinselele ezinkulu, ezivame ukubonakala emishinini ephatha amandla kagesi aphezulu: umphumela wokulandela umkhondo kanye nokukhishwa kwe-corona.
Uyini umphumela wokulandelela?
Embonini eyaziwa nangokuthi ibhande elomile noma i-arborescence kagesi, umphumela wokulandela umkhondo ubhekisela ekucekeleni phansi kwe-dielectric kwento evalelayo, inqubo engabuyiseleki emuva esuselwe ekukhishweni kukagesi ingxenye eqhubekela phambili ngaphakathi noma phezu kwempahla ye-dielectric uma ingaphansi kokuphakama isikhathi eside. -voltage ukucindezeleka kagesi.
Ukuphuma kweCorona
Enye ingozi izintambo ezisebenza emoyeni ezizisekelayo ezisebenza ngazo lapho zifakwe emibhoshongweni enamandla amakhulu umphumela we-corona, owaziwa nangokuthi ukukhishwa kwe-corona, okuchazwa ngokuthi i-ionization yegesi ezungeza ikhondukta eshajiwe.Ukuze kufakwe ikhebula le-fiber optic, igesi umoya ngokwawo, ozungeza umugqa wokudlulisela.
Umthelela we-corona ukhona kuwo wonke amadivaysi nasekufakeni okusebenza noma ohambisa ugesi.Ezimpilweni zethu zansuku zonke, lokhu ngokuvamile akubonakali futhi asithinti kakhulu ngenxa yama-voltage namandla kagesi esivame ukuwasebenzisa.Nokho, emibhoshongweni yamandla kagesi aphezulu, ama-voltage ahamba emigqeni yawo aphezulu kakhulu (kusuka ku-66 kV kuya ku-115 kV), okwenza umphumela we-corona okhiqizwa yilawa makhondatha ube banzi kakhulu.
Uma evezwe ezimweni zangaphandle, izintambo zithonywa izici ezimbili ezibalulekile: umswakama ohlobene komoya kanye nenkomba yokungcoliswa kwemvelo.Ngomswakama owengeziwe, amanzi amaningi ahlangana phezu kwekhebula;futhi lapho ukungcoliswa kwemvelo kukhulu, izinhlayiya ezengeziwe (uthuli, izinsimbi ezisindayo, amaminerali) zizovaleleka kumaconsi amanzi akhiwe.
Lawa maconsi anokungcola abe yi-conductive, lapho umphumela we-corona womugqa we-high-voltage ufinyelela amaconsi amabili asondelene ngokwanele komunye nomunye, i-arc kagesi idalwa, ikhiqiza ukushisa phakathi kwabo futhi ilulaza impahla yejacket yekhebula.
Ukuvikela ikhebula nezinto ezilwa nokulandela umkhondo
Kunconywa kakhulu ukusebenzisa izinto ezilwa nokulandelela lapho ubekaIntambo ye-fiber optic ye-ADSSseduze kwemishini nezinsiza eziphatha amandla kagesi angu-12 kV afika ku-25 kV.Lokhu kungamelana kangcono nemiphumela yokukhishwa kukagesi, kunciphise imiphumela ye-ionization, ukufudumeza, nokuwohloka kwezintambo.
Izinto zokulwa nokulandela umkhondo zihlukaniswe ngezigaba ezimbili ezinkulu, izinto zekilasi A nezinto zekilasi B:
Izinto ze-Class A
Izinto ze-Class A yilezo ezihlangabezana nenqubo yokumelana ngokusekelwe ku-voltage esetshenzisiwe kanye nenkomba yokungcola ehlolwe ngaphansi kwezinga le-IEEE P1222 2011, lokhu kuthathwa ngokuthi "okujwayelekile" emakethe.
Izinto ze-Class B
Izinto ze-Class B yilezo ezingekho ngaphansi kwesilinganiso, lokhu akusho ukuthi lezi zinto azikwazi ukuvikela umphumela wokulandelela, kodwa kunalokho, zibuswa amapharamitha noma izimo ezikhethekile ezichazwe umenzi, noma izinhlelo zokusebenza ezikhethekile. noma izidingo eziqinile, lesi sigaba singachazwa ngokuthi “ngokwesiko”.
Amathiphu weIkhebula le-ADSSukufakwa emibhoshongweni enamandla kagesi
Ukulungiselela kuyisihluthulelo.Kubalulekile ukucabangela inkomba yokungcola kanye ne-voltage yokufaka lapho ikhebula le-fiber optic elizisekelayo libekwe embhoshongweni onobude, onamandla kagesi.Uma nje singaphakathi kwemingcele esungulwe izinga le-IEEE P1222-2011, singasebenzisa impahla yekilasi A, efinyeleleka kalula emakethe;ezimweni ezinzima kakhulu zemvelo noma ama-voltage aphezulu, kuyadingeka ukusebenzisa izinto zekilasi B.
Xhumana nomkhiqizi wekhebula lakho ukuze uthole uhlobo lwento engasetshenziswa ukuvikela kangcono ubuqotho bekhebula ekufakeni kwakho, ukuhlangabezana nezimo lapho ikhebula lizovezwa khona.
Singakusiza kanjani?
EyethuOnjiniyela be-GL FIBER® nochwepheshe bokuthengisazibheke ngabomvu ukukusiza ukuthi unike amandla ukufaka kwakho, xhumana nathi namuhla futhi uhlole inhlobonhlobo yethu yezintambo ze-fiber optic ze-ADSS ezitholakalayo nezinto ezilwa nokulandela umkhondo noma izinto zejakhethi ezijwayelekile lapha.
