Intambo yokubona ye-OPGWibizwa nangokuthi i-optical fibre composite overhead wire yaphansi. Ikhebula le-OPGW optical Cable OPGW libeka i-optical fibre entanjeni yaphansi yolayini wokudlulisa we-overhead high-voltage ukuze yakhe inethiwekhi yokuxhumana ye-optical fiber entanjeni yokudlulisela. Lesi sakhiwo sinemisebenzi emibili yocingo oluphansi nokuxhumana, futhi ngokuvamile sibizwa ngokuthi i-OPGW optical cable. Idizayini yokufaka ye-OPGW kufanele icabangele ukuhlotshaniswa nokucindezelwa kwentambo, igebe lokucwila kanye ne-insulation, futhi umthwalo wayo akufanele udlule ububanzi obuvumelekile bemibhoshongo nezisekelo ezikhona. Ngakho-ke, ijika lesici kufanele libalwe ngokuvumelana nemingcele yezobuchwepheshe eyinhloko ye-OPGW ekhethiwe, futhi isakhiwo, uhlaka kanye nemidwebo yokufaka yebhokisi lokuhlangana, i-hardware ehlukahlukene kanye nezesekeli kufanele yakhelwe ngokuhambisana nobunjiniyela bangempela. Ukufunda okunwetshiwe: Ngabe abakhiqizi bezintambo ze-OPGW baqinisekisa kanjani ikhwalithi yezintambo ezibonakalayo
Ukucatshangelwa kwesakhiwo sokufakwa kwentambo yokubona ye-OPGW
1. Ukwelashwa kokunwetshwa kokuqala
Ukuze ukwelashwa kokunwetshwa kokuqala kwe-OPGW, indlela yokupholisa ingasetshenziswa, okungukuthi, isilinganiso se-aluminium-steel ye-OPGW siyabuyekezwa, futhi ukwelulwa kokuqala kuphathwa ngokubhekisela enanini lokupholisa locingo olufanayo noma umhlabathi. ucingo.
2. Ukuklanywa kwezinyathelo zokulwa nokudlidliza
Phakathi kwezinto ezisetshenziswa yi-OPGW, i-tension clamp iwuhlobo locingo olusontelwe ngaphambili, futhi intambo yocingo yokumiswa ifakwe ngocingo olusontekile ngaphambili kanye ne-rubber gasket. Lezi zinhlobo ezimbili zokufakwa zinamandla athile okulwa nokudlidliza. Ukuze kuthuthukiswe amandla okumelana nokudlidliza, kungenzeka ukuthi ucabange ukufaka isando esilwa nokudlidliza, esivame ukubalwa ngokuya nge-span:
Uma i-span ingaphansi noma ilingana no-300M, faka isando esilwa nokudlidliza;
Uma i-span ingu>300M, faka izando ezimbili ezilwa nokudlidliza.
3. Izinkinga okufanele zinakwe ekwakhiweni nasekumisweni kwe-OPGW
Ukwakhiwa nokumiswa kwe-OPGW kuhlukile emicu yensimbi evamile. Ukunakekelwa kufanele kuthathwe ukuze kuvinjelwe ukulimala okungapheli ukuze kugwenywe ukuthikameza ukusebenza kwe-fiber optical esikhathini esizayo, futhi kufanele kugxile kulokhu: I-OPGW torsion, i-micro-bending, ingcindezi yendawo ye-radial ngaphandle kwesiqeshana kanye nokungcoliswa kwe-optical fiber. Ngakho-ke, esigabeni sokwakha, izinyathelo ezilandelayo ezisebenzayo kufanele zithathwe ukuze kuxazululwe:
(1) Vimbela i-OPGW ekusonteni
Faka i-counterweight kanye ne-anti-twist idivayisi ebhodini kanye nesigxivizo sokuqinisa;
Yamukela i-pulley ekhethekile ye-double-groove;
Umshini we-tension line winch kabili;
(2) Vimbela futhi unciphise i-microbending kanye nengcindezi ye-OPGW
Awekho ama-engeli ashubile avunyelwe (indawo encane yokugoba ingu-500mm); ububanzi bentambo ye-OPGW reel akufanele ibe ngaphansi kuka-1500mm;
Ububanzi be-pulley kufanele bube ngaphezu kwama-25 ububanzi be-OPGW, ngokuvamile bungabi ngaphansi kuka-500mm; uhlangothi lwangaphakathi lwe-pulley kufanele lube nenayiloni noma ulwelwesi lwerabha ukuvimbela ukunwaya ubuso be-OPGW;
Izintambo ezifanele zokudonsa nezikhokhayo;
Cacisa ubude bekhoyili obukhulu be-OPGW ukuthi bube ngu-6000M ukuze uvimbele izikhathi lapho i-pulley idlula khona;
I-engeli yokuzungezisa umugqa yenkokhelo eqhubekayo ikhawulelwe ku-≤30°. Esigabeni sokucindezeleka senkokhelo, isiqondiso se-OPGW ngemva kwekhona kufanele sibe sesimweni esithi "C";
(3) Ukulawulwa kwengcindezi yokukhokha:
Thola ukukhokhelwa kwe-hydraulic tension kanye nogandaganda onethuluzi lokukhipha ingcindezi;
Nciphisa isivinini sokukhokha ≤ 0.5 m/s;
(4) Vimbela ukungcoliswa kwe-fiber
Ekwakhiweni nasekumisweni kwe-OPGW, kufanele kuqashelwe ukuhlanganisa iziphetho;
Okokugcina, sidinga ukukhumbuza wonke umuntu ukuthi ngaphambi kokuba i-OPGW ifike kusayithi, ngaphambi kokwakhiwa, ngemva kokuqedwa kokumiswa kanye nokuxhumeka kwe-fiber optical kanye nokuqedwa kwawo wonke ukwakhiwa komugqa, ukuhlolwa kokwamukelwa kwe-OPGW fiber attenuation kufanele kwenziwe. endaweni ngesikhathi.
