Xa sithetha ngofakelo lwasemoyeni oluzixhasayo, esinye sezona zicelo zixhaphakileyo zothumelo lomgama omde kukubekwa kweentambo zefiber optic kwiinqaba zombane ophezulu.
Izakhiwo zangoku ezinevoltage ephezulu zithumela uhlobo olunomtsalane kakhulu lofakelo kuba lunciphisa utyalo-mali kwiziseko ezingundoqo ezifunekayo ukwenza amakhonkco amatsha e-fiber optic, ezi sele ezakhiwe ngaphakathi.Kodwa imigca ekwiinqaba zombane ophezulu ihlala inika imiceli mngeni emikhulu, edla ngokubonwa kwisixhobo esiphatha amandla ombane aphezulu: isiphumo sokulandela umkhondo kunye nokukhutshwa kwecorona.
Yintoni umphumo wokulandelela?
Ekwaziwa kwishishini njengebhanti eyomileyo okanye i-arborescence yombane, isiphumo sokulandela umkhondo sibhekisa kwintshabalalo yedielectric yezinto ezikhuselayo, inkqubo engenakubuyiselwa ephuma kukukhutshwa kombane okungaphelelanga okuhamba ngaphakathi okanye kumphezulu wesixhobo sombane xa siphantsi kwexesha elide. -i-voltage yoxinzelelo lombane.
Ukukhutshwa kweCorona
Omnye umngcipheko wokuba iintambo zasemoyeni ezizixhasayo zisebenza xa zifakwe kwiinqaba zombane ophezulu yimpembelelo ye-corona, ekwabizwa ngokuba yi-corona discharge, echazwa njenge-ionization yerhasi ejikeleze i-conductor ehlawulisiweyo.Ufakelo lwefiber optic cable, igesi ngumoya ngokwawo, ojikeleze umgca wothumelo.
Impembelelo ye-corona ikhona kuzo zonke izixhobo kunye nofakelo olusebenza okanye oluqhuba umbane.Kubomi bethu bemihla ngemihla, oku ngokuqhelekileyo akubonakali kwaye akusichaphazeli kakhulu ngenxa yamandla ombane kunye namandla ombane esiqhele ukuwasebenzisa.Nangona kunjalo, kwiinqaba zombane ophezulu, ii-voltages ezihamba kwimizila yazo ziphezulu kakhulu (ukusuka kwi-66 kV ukuya kwi-115 kV), ebangela ukuba umphumo we-corona oveliswe ngaba baqhubi ukuba ube banzi kakhulu.
Xa bevezwe kwiimeko zangaphandle, iintambo ziphenjelelwa zizinto ezimbini ezibalulekileyo: ukufuma komoya ohambelanayo kunye nesalathiso songcoliseko lokusingqongileyo.Ngomswakama ongaphezulu, amanzi amaninzi adibanisa phezu kwentambo;kwaye okukhona ukungcoliseka kwendalo, kokukhona amasuntswana (uthuli, isinyithi esinzima, iiminerali) aya kubanjiswa kumathontsi amanzi akhiweyo.
Ezi zithontsi ezinokungcola ziba yi-conductive, xa umphumo we-corona yomgca we-high-voltage ufikelela kumaconsi amabini asondelene ngokwaneleyo omnye komnye, i-arc yombane iyadalwa, ivelisa ukushisa phakathi kwabo kunye nokuthotywa kwezinto zebhatyi yekhebula.
Ukukhuselwa kwekhebula kunye nezinto ezichasayo zokulandela umkhondo
Kucetyiswa ngamandla ukuba usebenzise izinto ezichasene nokulandela umkhondo xa ubekaADSS intambo yefiber opticsecaleni kwezixhobo kunye nezibonelelo ezilawula amandla ombane we-12 kV ukuya kuma-25 kV.Ezi zinokuthi zixhathise ngcono imiphumo yokukhutshwa kombane, ukunciphisa imiphumo ye-ionization, ukufudumeza, kunye nokuthotywa kweentambo.
Izinto ezichasene nokulandela umkhondo zohlulwe zibe ziindidi ezimbini ezinkulu, izixhobo zeklasi A kunye nezixhobo zeklasi B:
Izinto zeKlasi A
Izinto zeKlasi A zezo zihlangabezana neendlela zokuchasana ezisekelwe kwi-voltage esetyenzisiweyo kunye nesalathisi songcoliseko esivavanywa phantsi komgangatho we-IEEE P1222 2011, oku kuthathwa njenge "standard" kwimarike.
Izinto zeKlasi B
Izinto zeKlasi B zezo zingekho phantsi komgangatho, oku akuthethi ukuba ezi zixhobo azisebenzi ukukhusela kwisiphumo sokulandelela, kodwa kunoko, zilawulwa yiparameters okanye iimeko ezikhethekileyo ezichazwe ngumenzi, nokuba zizicelo ezikhethekileyo. okanye iimfuno ezingqongqo, olu didi lunokuchazwa “njengesiqhelo”.
Iingcebiso zeIntambo ye-ADSSUfakelo kwiinqaba eziphezulu zombane
Ukulungiselela ngundoqo.Kuyimfuneko ukuqwalasela isalathisi songcoliseko kunye nombane wofakelo xa intambo ye-fiber optic ezixhasayo ibekwe kumgama omde, inqaba ephezulu yombane.Ngethuba nje singaphakathi kweeparitha ezisungulwe ngumgangatho we-IEEE P1222-2011, sinokusebenzisa izinto zeklasi A, ezifikeleleke ngakumbi kwiimarike;kwiimeko ezinzima ngakumbi zokusingqongileyo okanye ii-voltages eziphezulu, kuyimfuneko ukusebenzisa izixhobo zodidi B.
Qhagamshelana nomenzi wakho wentambo ukuze uqinisekise uhlobo lwezinto ezinokuthi zisetyenziswe ukukhusela ngcono ukuthembeka kwentambo kufakelo lwakho, ukuhlangabezana neemeko apho intambo iya kuvezwa khona.
