OPGW intambo yokubonaukwabizwa ngokuba yi-optical fiber composite ngocingo olungaphezulu komhlaba.Intambo ye-OPGW ye-optical cable I-OPGW i-optical cable ibeka i-fiber optical kucingo oluphantsi lwe-overhead high-voltage transmission line ukwenza i-optical fiber network network kumgca wothumelo.Esi sakhiwo sinemisebenzi emibini yocingo lomhlaba kunye nonxibelelwano, kwaye ngokuqhelekileyo kuthiwa yi-OPGW optical cable.Uyilo lofakelo lwe-OPGW kufuneka luqwalasele ulungelelwaniso kunye noxinzelelo lwecingo, i-sag kunye ne-gap yokufakelwa, kwaye umthwalo wayo akufanele udlule uluhlu oluvumelekileyo lweenqaba ezikhoyo kunye neziseko.Ngoko ke, ijika leempawu kufuneka libalwe ngokweeparitha eziphambili zobugcisa ze-OPGW ekhethiweyo, kunye ne-layout, i-outline kunye nokufakwa kwemidwebo yebhokisi ye-junction, i-hardware eyahlukeneyo kunye nezixhobo kufuneka zenziwe ngokudibanisa nobunjineli bokwenene.Ufundo olwandisiweyo: Ingaba abavelisi beentambo ze-OPGW baqinisekisa njani umgangatho weentambo zamehlo
OPGW optical intambo yofakelo lwesakhiwo imiba yoyilo
1. Unyango lokwandiswa kokuqala
Kunyango lokwandiswa kokuqala kwe-OPGW, indlela yokupholisa ingasetyenziselwa, oko kukuthi, umlinganiselo we-aluminium-steel we-OPGW uhlaziywa, kwaye ukunyuswa kokuqala kunyangwa ngokubhekiselele kwixabiso lokupholisa lecingo elifanayo okanye umhlaba. ucingo.
2. Uyilo lwamanyathelo okulwa nokungcangcazela
Phakathi kwezinto ezisetyenzisiweyo yi-OPGW, i-tension clamp yohlobo lwe-wire pre-twisted, kunye ne-suspension wire clamp ixhotyiswe nge-wire pre-twisted kunye ne-rubber gasket.Ezi ntlobo zimbini zofakelo zinamandla athile okuthintela ukungcangcazela.Ukuze uqinise ngakumbi amandla okulwa nokungcangcazela, kunokwenzeka ukuba kuqwalaselwe ukufakela isando esichasayo, esibalwe ngokubanzi ngokwexesha:
Xa i-span ingaphantsi okanye ilingana ne-300M, faka isando esichasene ne-vibration;
Xa i-span is> 300M, faka iihamile ezimbini zokulwa nokungcangcazela.
3. Iingxaki ekufuneka zithathelwe ingqalelo ekwakhiweni nasekumisweni kwe-OPGW
Ukwakhiwa kunye nokwakhiwa kwe-OPGW kwahlukile kwimicu yentsimbi eqhelekileyo.Ukunyamekela kufuneka kuthathwe ukukhusela umonakalo osisigxina ukuphepha ukuchaphazela ukusebenza kwe-fiber optical kwixesha elizayo, kwaye kufuneka kugxininise kwi: I-OPGW torsion, i-micro-bending, uxinzelelo lwe-radial yendawo ngaphandle kwekliphu kunye nokungcola kwi-fiber optical.Ke ngoko, kwinqanaba lokwakha, la manyathelo alandelayo asebenzayo kufuneka athathwe ukuyisombulula:
(1) Thintela i-OPGW ekujikeni
Faka i-counterweight kunye ne-anti-twist isixhobo ebhodini kunye ne-clamp yokuqinisa;
Yamkela i-pulley ekhethekileyo ye-double-groove;
Umatshini wentambo yoxinzelelo kunye ne-winch ephindwe kabini;
(2) Ukuthintela kunye nokunciphisa i-microbending kunye noxinzelelo lwe-OPGW
Akukho ziengile ezibukhali zivumelekileyo (ubuncinane beradiyasi yokugoba yi-500mm);ububanzi bentambo yentambo ye-OPGW akufanele ibe ngaphantsi kwe-1500mm;
Idayamitha ye-pulley kufuneka ibe ngaphezu kwamaxesha angama-25 ububanzi be-OPGW, ngokuqhelekileyo ingabi ngaphantsi kwe-500mm;icala elingaphakathi le-pulley kufuneka libe ne-nylon okanye i-rubber lining ukuthintela ukukrwela umphezulu we-OPGW;
Iingcingo zokutsalwa ezifanelekileyo kunye nezixhobo zokuhlawula;
Cacisa ubude be-coil ephezulu ye-OPGW ukuba ibe yi-6000M ukuthintela inani lamaxesha okugqithisa i-pulley;
I-angle yokujikeleza komgca wokuhlawula okuqhubekayo kunqunyelwe kwi-≤30 °.Kwicandelo loxinzelelo lokuhlawula, isalathiso se-OPGW emva kwekona kufuneka sibe nesimo se "C";
(3) Ukulawulwa koxinzelelo lwentlawulo:
Yamkela intlawulo yoxinzelelo lwehydraulic kunye netrektara enesixhobo sokukhulula uxinzelelo;
Ukunciphisa isantya sokuhlawula ≤ 0.5 m / s;
(4) Thintela ungcoliseko lwefiber
Kulwakhiwo kunye nokwakhiwa kwe-OPGW, ingqwalasela kufuneka ihlawulwe ekufakeni iziphelo;
Ekugqibeleni, kufuneka sikhumbuze wonke umntu ukuba ngaphambi kokuba i-OPGW ifike kwindawo, ngaphambi kokwakhiwa, emva kokugqitywa kokwakhiwa kunye noxhumo lwefiber optical kunye nokugqitywa kokwakhiwa komgca wonke, uvavanyo lokumkela i-OPGW fiber attenuation kufuneka lwenziwe. kwindawo ngexesha.
