Nrog rau txoj kev loj hlob ntawm lub network, raws li qhov nruab nrab siv los xa cov ntaub ntawv hauv kev sib txuas hauv kev sib txuas, fiber ntau optical siv ntau thiab ntau dua los ntawm tib neeg vim nws qhov zoo ntawm kev sib kis tau zoo thiab qhov ntev. Raws li peb txhua tus paub, cov khoom siv kho qhov muag fiber ntau tsis yog cov khoom siv hluav taws xob thiab tuaj yeem tiv thaiv los ntawm inrush tam sim no. Optical cable kuj muaj kev tiv thaiv zoo. Cov khoom siv hlau hauv cov khoom siv kho qhov muag muaj qhov muaj txiaj ntsig zoo rau hauv av, thiab cov hluav taws xob tam sim no tsis yooj yim rau nkag mus rau hauv cov khoom siv kho qhov muag. Qhov ncaj qha faus optical cable muaj ib txheej armoring, yog li thaum cov kab hluav taws xob kho qhov muag raug ntaus los ntawm xob laim, qhov kho qhov muag cable kuj tuaj yeem hlawv lossis puas. Ntawm no, kuv yuav piav qhia meej txog cov kev ntsuas tseem ceeb rau kev tiv thaiv xob laim ntawm cov kab hluav taws xob kho qhov muag thiab cov khoom siv kho qhov muag hauv kev tsim kho cov phiaj xwm kev sib txuas.
Kev ntsuas 1. Rau kev tiv thaiv xob laim ntawm txoj kab ncaj nraim ntawm cov kab hluav taws xob kho qhov muag: ① Hauv cov txheej txheem hauv av hauv zos, cov hlau hauv cov khoom siv kho qhov muag yuav tsum tau txuas rau ntawm qhov sib koom ua ke, kom cov tub ntxhais muaj zog, cov txheej txheem ya raws thiab cov khoom siv tiv thaiv. txheej ntawm junction optical cable tseem txuas nrog. ② Raws li cov kev cai ntawm YDJ14-91, cov txheej txheem dej noo, txheej armor thiab cov tub ntxhais tseem ceeb yuav tsum tau txiav hluav taws xob ntawm cov khoom siv kho qhov muag, thiab lawv tsis yog hauv av, thiab nyob rau hauv ib lub xeev insulated rau hauv av, uas tuaj yeem zam qhov tsub zuj zuj ntawm induced xob laim tam sim no nyob rau hauv optical cable. Nws tuaj yeem zam tau tias cov hluav taws xob tam sim no hauv av tau nkag mus rau hauv cov khoom siv kho qhov muag los ntawm cov khoom siv hauv av vim qhov sib txawv ntawm qhov impedance ntawm cov hluav taws xob tiv thaiv cov xaim hluav taws xob thiab cov hlau tivthaiv ntawm optical cable rau hauv av voj.
Ntsuas 2. Rau cov khoom siv hluav taws xob siv hluav taws xob: cov hluav taws xob siv hluav taws xob yuav tsum tau txuas nrog hluav taws xob thiab hauv av txhua 2km. Thaum grounding, nws tuaj yeem raug grounded ncaj qha lossis los ntawm cov khoom siv tiv thaiv kev tiv thaiv zoo. Nyob rau hauv no txoj kev, lub ncua kev kawm ntawv hlau muaj kev tiv thaiv ntawm lub overhead av hlau.
Ntsuas 3. Tom qab lub optical cable nkag mus rau hauv lub thawv davhlau ya nyob twg, lub thawv davhlau ya nyob twg yuav tsum tau muab tso rau hauv av. Tom qab xob laim tam sim no nkag mus rau hauv cov hlau txheej ntawm cov khoom siv kho qhov muag, lub hauv paus ntawm lub thawv davhlau ya nyob twg tuaj yeem tso tawm cov xob laim tam sim no thiab ua lub luag haujlwm tiv thaiv. Qhov ncaj qha faus optical cable muaj ib txheej armor thiab cov tub ntxhais reinforcing, thiab sab nrauv sheath yog PE (polyethylene) sheath, uas tuaj yeem tiv thaiv corrosion thiab nas tom.
