Kev ntsuas los daws qhov teeb meem thermal stability ntawmOPGW kho qhov muag cable
1. Ua kom cov ntu ntawm cov khoom siv hluav taws xob
Yog tias qhov tam sim no tsis dhau ntau, cov hlau strand tuaj yeem nce los ntawm ib qho loj.Yog tias nws ntau dhau, nws raug nquahu kom siv cov khoom siv hluav taws xob zoo tiv thaiv hlau (xws li aluminium-clad steel stranded wire).Feem ntau, tsis tas yuav hloov tag nrho cov kab, tsuas yog cov kab lus nkag mus thiab tawm ntawm qhov chaw nres tsheb fais fab tuaj yeem hloov pauv, thiab qhov ntev yog txiav txim siab los ntawm kev suav.
2. Kev rho tawm thiab kev rwb thaiv tsev ntawm OPGW optical cable xob laim tiv thaiv kab rau cov khoom nkag thiab tawm
Qhov siab tshaj plaws tam sim no nyob rau hauv txoj kab tiv thaiv xob laim yog nyob rau ntawm txoj kab nkag thiab tawm.Yog tias ib txoj hlua ntawm cov insulators ntxiv rau cov kab hluav taws xob tiv thaiv ntawm qib no, tam sim no yuav tsis tuaj yeem nkag mus rau hauv lub substation.Lub sijhawm no, qhov siab tshaj plaws tam sim no tshwm sim hauv lub iav thib ob.Txawm hais tias tag nrho cov luv luv-circuit tam sim no hloov me ntsis, qhov kev tiv thaiv hauv av nce ntau, yog li cov kab hluav taws xob tiv thaiv tam sim no txo qis dua.Ob qhov teeb meem yuav tsum tau them sai sai rau thaum ntsuas qhov ntsuas no.Ib qho yog kev xaiv lub siab tsis kam ntawm cov hlua insulator, thiab lwm qhov yog qhov tsim nyog sib txuam ntawm cov av tiv thaiv ntawm txhua tus pej thuam kom txo qhov tam sim no hauv cov kab hluav taws xob tiv thaiv.
3. Siv ib txoj kab shunt los txo qhov tam sim no ntawm OPGW optical cable
Tus nqi ntawm OPGW kho qhov muag cable yog qhov siab, thiab nws tsis yooj yim rau tsuas yog nce qhov hla ntawm OPGW optical cable kom dais qhov luv-circuit tam sim no.Yog tias lwm txoj kab hluav taws xob tiv thaiv siv tus neeg xyuas pib zoo nrog cov impedance qis heev, nws tuaj yeem ua lub luag haujlwm zoo shunt thiab txo qhov tam sim no ntawm OPGW optical cable.Kev xaiv ntawm txoj kab shunt yuav tsum ua tau raws li cov hauv qab no: qhov impedance tsawg txaus los txo tus nqi tam sim no ntawm OPGW optical cable hauv qab tus nqi tso cai;txoj kab shunt nws tus kheej yuav tsum muaj qhov loj txaus tso cai tam sim no;txoj kab shunt yuav tsum ua tau raws li kev tiv thaiv kev tiv thaiv xob laim.Muaj lub zog txaus kev nyab xeeb.Txawm hais tias qhov kev tiv thaiv ntawm shunt kab tuaj yeem txo qis heev, nws cov inductive reactance txo qis, yog li lub luag haujlwm ntawm shunt kab muaj qee qhov txwv.Cov kab shunt tuaj yeem xaiv tau nyob rau hauv ntu raws li qhov luv luv-circuit tam sim no ntawm ntau qhov chaw ntawm txoj kab, tab sis kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias thaum lub shunt kab hloov qauv, vim hais tias cov kab shunt ua thinner, tam sim no ntau dua. faib rau OPGW kho qhov muag cable, yog li tam sim no ntawm OPGW kho qhov muag cable yuav dheev nce ntau, yog li kev xaiv ntawm cov kab shunt yuav tsum rov suav dua.
4. Xaiv ob qhov tshwj xeeb ntawm OPGW optical cables
Vim tias qhov luv-circuit tam sim no ntawm cov kab nkag thiab tawm ntawm lub chaw nres tsheb yog qhov loj tshaj plaws, OPGW optical cables nrog cov hlaws loj yog siv ntawm no, thaum OPGW optical cables nrog me me cross-section yog siv rau cov kab nkag thiab tawm mus deb. los ntawm substation.Qhov kev ntsuas no tsuas yog siv rau cov kab ntev thiab yuav tsum muab piv rau kev lag luam.Thaum xaiv ob hom OPGW optical cables, ob txoj kab shunt yuav tsum tau txiav txim siab tib lub sijhawm.Ntawm qhov kev sib tshuam ntawm ob kab, kev saib xyuas yuav tsum tau them rau kev hloov pauv tam sim no ntawm OPGW optical cable thiab xob laim tiv thaiv kab.
5. Kev faib tawm hauv av
Yog hais tias ob peb lub hauv av siv los txuas cov cuab yeej siv hauv av ntawm lub davhlau ya nyob twg mus rau hauv daim phiaj hauv av ntawm lub substation, ib feem ntawm qhov luv-circuit tam sim no yuav nkag mus rau hauv lub substation hauv av, txo qhov tam sim no ntawm OPGW optical cable thiab xob laim.Thaum siv qhov ntsuas no, sab laj nrog lub chaw ua haujlwm.
6. Kev sib txuas ntawm cov kab hluav taws xob tiv thaiv ntau lub voj voog
Yog tias cov khoom siv hauv av ntawm ntau lub davhlau ya nyob twg txuas nrog, qhov luv-circuit tam sim no tuaj yeem ntws mus rau hauv lub substation raws li cov hluav taws xob hluav taws xob ntau, kom cov hluav taws xob ib leeg tam sim no me dua.Yog tias tseem muaj teeb meem nrog lub thermal stability ntawm xob laim tiv thaiv hlau ntawm lub iav thib ob, cov khoom siv hauv av ntawm lub hauv paus thib ob tuaj yeem txuas nrog, thiab lwm yam.Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias thaum muaj ntau lub tsev txuas nrog, qhov teeb meem ntawm kev tiv thaiv kev tiv thaiv zero-sequence yuav tsum tau kawm.
7. Cov kab nkag thiab tawm cov khw muag khoom siv ADSS optical cables
Thaum OPGW optical cable raug tshem tawm, thiab ADSS (tag nrho-dielectric self-supporting) optical cable siv, qhov siab tshaj plaws luv luv tam sim no hauv OPGW optical cable tuaj yeem suav tias yog qhov tam sim no ntws mus rau lub substation thaum lub hauv paus thib ob. ua tsis tiav, thiab qhov tam sim no siab dua li ntawm thawj lub hauv paus pej thuam.Lub luv luv Circuit Court tam sim no me me.Yog li ntawd, thaum ADSS optical cable siv rau kev nkag thiab tawm kab thaiv, qhov siab tshaj plaws luv luv tam sim no tuaj yeem xam raws li qhov luv-circuit tam sim no ntawm lub sij hawm txhaum ntawm lub hauv paus pej thuam thib ob thaum lub sij hawm thermal tsom ntawm OPGW optical. cable, yog li ntawd cov thermal stability yuav tsum tau rau OPGW optical cable raug txo qis heev.
Lub thermal stability ntawm optical fiberOverhead Composite Ground Wire (OPGW)yuav tsum tau txiav txim siab tag nrho hauv cov txheej txheem tsim thiab xaiv, thiab kev ntsuas sib txawv yuav tsum tau ua raws li cov qauv tshwj xeeb thiab txoj hauv kev tiag tiag ntawm OPGW optical cable kom tsis txhob muaj kev puas tsuaj los ntawm ib-theem grounding luv-circuit tam sim no rau OPGW optical cable.kev puas tsuaj, thiab txhim kho kev ua haujlwm kev ntseeg siab ntawm OPGW optical cable.
