OPGW Tshaj -Pulley Test
Xeem Lub Hom Phiaj
Kev sim rubey yog ua los xyuas kom meej tias OPGW yuav tsis raug puas tsuaj lossis muaj nws cov yam ntxwv kev ua haujlwm tsis zoo thaum zawv zawg hla rub lub qhov ntev ntawm qhov pom zoo. Qhov kev xeem no yuav tsum ua raws li DL/T 832-2016.
Kuaj teeb
Kev teeb tsa kev ntsuas lub rubey raug pom nyob rau hauv daim duab 1. Cov qauv kuaj tau ruaj ntseg ntawm ob qho kawg uas siv cov hlua khi tsim nyog. Lub teeb pom kev zoo thiab lub ntsuas hluav taws xob kho qhov muag tau teeb tsa ntawm qhov kawg ntawm cov fiber ntau hauv kev sim ntsuas qhov poob ntawm fiber ntau. Ua ntej kev sim, qhov pib, qhov nruab nrab, thiab qhov kawg ntawm qhov kev xeem yuav tsum tau cim kom meej. Tom qab kev sim, ntsuas qhov ellipticity ntawm cov kab hluav taws xob kho qhov muag thiab nws cov khoom, muab piv nrog qhov siab tshaj plaws ntawm cov pa oxygen (MAOC) ntawm qhov chaw sib txuas.
Txoj Kev Xeem
① Nruab cov qauv OPGW ntawm cov khoom siv rub. Qhov kev sim kho qhov muag cable ntev yuav tsum tsis pub tsawg tshaj 100 m, nrog rau seem ntawm nro clamp installation cov ntsiab lus tsis pub tsawg tshaj 5 m. Fusion splice cov fibers optical rau hauv ib lub voj los ntsuas fiber ntau attenuation.
② Hla lub cable los ntawm lub pulleys nrog ib txoj kab uas hla tsis pub tsawg tshaj 40 npaug ntawm cable. Rub lub cable rau pem hauv ntej thiab rov qab 10 zaug txhua, siv lub zog tensile ntawm 15% RTS. Qhov kev ncua deb yog 2 m, nrog lub hnab ntawv lub kaum sab xis ntawm 30 degree.
③ Thaum lub cable hla dhau lub pulley rau lub sij hawm 1 thiab 10, ntsuas lub cable txoj kab uas hla ntawm qhov pib, nruab nrab point, thiab kawg ntawm lub rub seem siv ib tug micrometer. Tom qab kev sim, rub tawm cov hlua sab nraud thiab ntsuas txoj kab uas hla ntawm lub raj kho qhov muag ntawm qhov chaw cim.
Kev Xeem Xeem
① Tom qab kev sim, qhov poob ntawm qhov ntsuas fiber ntau ntawm 1550 nm wavelength yuav tsum tsis pub tshaj 0.01 dB / km. Ib qho kev poob mus tas li nce siab tshaj tus nqi teev tseg yuav raug suav tias yog qhov kev sim tsis ua tiav.
② Lub ovality ntawm chav kho qhov muag yuav tsum tsis pub tshaj 10% ntawm nws MAOC.
③ OPGW kuaj yuav tsum tsis muaj kev puas tsuaj.
