Ibhukwana le-GL Technology lakamuva lokufakwa kwe-OPGW
Manje, Asiqhubeke nesifundo sethuOPGW Hardware kanye IzesekeliUkufakwa namuhla.
Faka okokufaka nezinto ezisetshenziswayo emahoreni angu-48 ngemva kokuqinisa izintambo esigabeni sokudonsa ukuze ugweme ukulimala okungadingekile kumafayibha abangelwa ukukhathala ngokweqile kwentambo, ngoba ikhebula lingahuzuka kalula noma lidlidlizele ku-pulley.Ukufakwa kanye nezinsiza ze-OPGW kuvame ukufaka: i-tension clamp,
i-suspension clamp, intambo yomhlaba ekhethekile, i-vibration damper, izinsimbi zempi, i-downlead clamp, ibhokisi elihlangene nokunye.
1. Ukufakwa kwe-tension clamp
I-tension clamp iyi-hardware eyisihluthulelo yokufaka i-OPGW engagcini nje ngokulungisa ikhebula esigxotsheni nasembhoshongweni futhi inikeze ukucindezela okukhulu kodwa futhi ibambe ikhebula iqinise kuyilapho ingeqi umfutho oseceleni we-OPGW.I-tension clamp ivamise ukusetshenziswa embhoshongweni wokunqamula, umbhoshongo osekhoneni ongaphezu kuka-15°, i-cabling.
umbhoshongo noma umbhoshongo wesigxobo womehluko omkhulu wokuphakama.I-standard pre-stranding tension clamp yakhiwe ngocingo oluxhumeke ngaphakathi, intambo yangaphandle, i-thimble, bolt, nut nokunye.
Izinyathelo zokufaka:
A. Lungisa ihadiwe embhoshongweni ngemva kokuba i-arc yekhebula isilungisiwe ngezinto ezisetshenziswayo zokuvala.
B. Donsa intambo yangaphandle ye-tension esethwe ngeluphu emise okwenhliziyo yehardware yezokuthutha.Yenza intambo elengayo ihambisane nekhebula bese umaka ikhebula endaweni yokufaka umbala ocingweni.
C. Fanisa intambo yangaphakathi exhumeke inophawu kukhebula, bese, uhlehle iqembu lokuqala lentambo exhunywe ngaphambilini kukhebula.Hlehlisa ezinye izintambo ezixhunywe ngaphambili noma faka i-flake eliphansi ngophawu lombala ukuze uqinisekise ukuthi zonke izintambo ezixhunywe ngaphambili zihlehla ndawonye ziqine futhi iziphetho zisikiwe futhi
kuhlelwe kahle.Vimbela izintambo ezixhunywe ngaphambili ekushintsheni ngokuzikhandla ngokweqile ukuze ungathinti ibanga lamabhawodi.
D. Faka intambo exhunywe ngaphambili emgqonyeni bese uqondana nophawu lwesigaba esiphambanayo lwentambo yokuxhuma yangaphandle ne-earmark yombala yocingo oluxhumayo lwangaphakathi.Bese-ke, hlehlisa intambo engaphandle.Gcina isikhala silingana noma ngabe i-reel kusuka engxenyeni eyodwa noma izingxenye ezimbili.
2 Ukufakwa kwe-clamp yokumisa
I-pre-stranding clamp isetshenziselwa ukulenga ikhebula ngaphansi, elakhiwe ngocingo oluxhumeke ngaphakathi, ucingo oluxhumeke ngaphandle, ibhande lenjoloba, i-alloy ingot crust, ibhawodi, inati kanye ne-gasket.
Izinyathelo zokufaka:
A. Maka indawo emile yokumiswa kukhebuli ye-OPGW bese uhlehlisa ucingo oluxhumeke ngaphakathi olusuka engxenyeni emaphakathi, ephawulwe.Sebenzisa izandla hhayi amathuluzi ukuhlehlisa ingxenye yokunqamula ngemva kokujikijela zonke izintambo ezixhumene ngaphakathi.
B. Beka isikhungo sentambo yangaphakathi exhumekile phakathi nendawo ye-rubber clamp futhi uhlanganiswe ngeteyipu ehlambalazayo, Bese, ubophela intambo engaphandle kwi-clamp yesigebengu kanye nejika noma ufake i-Hake ephansi.Gcina isikhala silingana futhi ugweme ukuphambana.
C. Beka isikhungo sokuchoboza phakathi nendawo ekugcineni kocingo olunciphile klebhula ibhawodi bese ulilungisa.Bese uxhuma ngesisekelo sokumiswa, klebhula ibhawodi bese ulenga embhoshongweni.
3. Ukufakwa kwe-vibration damper
I-Vibration damper isetshenziselwa ukususa noma ukukhulula ukudlidliza okubangelwa yizo zonke izinhlobo zezinto ngesikhathi sokusebenza kwe-OPGW ukuze kuvikelwe ikhebula le-OPGW futhi kunwetshwe ukuphila kwekhebula.
3.1 Isimiso sokwabiwa kwenombolo yokufaka:
Inombolo ye-vibration damper inikezwa ngokulandela isimiso esilandelayo: i-span≤250m: amasethi angu-2;ububanzi: 250 ~ 500m (kuhlanganise 500m), 4 amasethi;ububanzi: 500 ~ 750m (kuhlanganise 750m), 6 amasethi;lapho ububanzi bungaphezu kuka-1000m, uhlelo lokwabiwa kufanele lushintshwe ngokuvumelana nesimo somugqa.
3.2 Indawo yokufaka
(1) Ifomula yokubala:
Ifomula yekhompyutha:
D: ububanzi bekhebula (mm)
T : ikhebula eliyisilinganiso sokucindezeleka sonyaka (kN), ngokuvamile esingu-20% RTS
M: isisindo seyunithi yekhebula (kg/km)
(2) Indawo yokuqala yokufakwa kwe-vibration damper: indawo yokuqala ye-L1 umugqa omaphakathi we-clamp yokumiswa kanye nomugqa omaphakathi we-thimble ye-tension clamp;indawo yokuqala ye-L2 iyisikhungo se-damper yokuqala yokudlidliza, indawo yokuqala ye-L3 iyisikhungo se-damper yesibili yokudlidliza, njalonjalo.
(3) I-damper yokuqala yokudlidliza kufanele ifakwe ocingweni olungaphakathi lwezisekeli, nezinye.
afakwe ezindongeni zempi ezikhethekile ezivela ku-damper yesibili yokudlidliza.
4. Ukufakwa kocingo lomhlaba
I-earth wire isetshenziswa kakhulu ukunikeza ukufinyelela kugesi onqamulelayo lapho i-OPGW iphansi.Iboshwe ngocingo lwe-alloy futhi ixhunywe ngezesekeli nge-parallel groove clamp noma umfanekiso kanti enye ingxenye ixhunywe emgodini ophansi wombhoshongo.Ukufakwa kocingo lomhlaba kufanele kube ubuhle, ubude obufanele, ngaphandle kokugoba noma ukusonteka.Amaphoyinti okuxhuma kufanele abe noxhumana nabo abahle futhi ahlale emunye
yonke imigqa.
5. Ukufakwa kwe-downlead clamp, ithreyi yekhebula kanye nebhokisi elihlangene
Ikhebula endaweni yokuhlanganisa embhoshongweni kufanele ihlukaniswe ngemuva kokuhola phansi.Eceleni kwezinhlangothi ezimbili zocingo lomhlaba ukuma kombhoshongo kuya emzimbeni wombhoshongo bese uhola ngaphakathi komzimba wombhoshongo.Irediyasi egotshwayo yomzila lapho ukudonsela phansi kudlula khona akufanele kube ngaphansi kuka-1m, futhi irediyasi encane yokugoba kufanele ithenjiswe phakathi nokusebenza, ngokuvamile ibe ngaphezu kuka-0.5m.Ngemuva kokuthi ikhebula liholelwe phansi, i-downlead clamp isetshenziswa ukubopha
ikhebula ezintweni eziyisisekelo noma enye impahla yekhebula.I-anchor ear i-downlead clamp yohlobo lwendlebe kufanele isetshenziswe uma iwumthofu eduze kwesigxobo sikakhonkolo (okunjalo
njengesiteshi sokuguqula, isakhiwo sesitshalo samandla) .I-Cable downlead kufanele iqonde futhi ibe yinhle.Ibhokisi elihlanganyelwe kanye nethreyi yekhebula kufanele kufakwe endaweni efanelekile embhoshongweni, futhi cishe i-8 ~ 10m ngaphezu kwendawo yedatha yombhoshongo.Ukufakwa kufanele kuqine futhi yonke imigqa kufanele ihlanganiswe.
