opgw tambo dzinonyanya kushandiswa pamitsetse ine voltage mazinga e500KV, 220KV, uye 110KV.Kukanganiswa nezvinhu zvakaita sekudzimwa kwemagetsi emutsetse, chengetedzo, nezvimwewo, zvinonyanya kushandiswa mumitsara ichangobva kuvakwa.Overhead ground wire composite optical cable (OPGW) inofanira kudzika yakavimbika panzvimbo yekupinda kuitira kudzivirira tambo yemaziso kuti isatyorwe ne-induced voltage uye kuvhiringwa kana dunhu diki rikaitika mumutsara.Zvinodiwa zvegrounding ndezvizvi:
1. Nzira yekugadzika kwetambo ye optical yebhokisi re splice pane chimiro: pamusoro pechigadziro, iyo yakaderera yakagadziriswa nzvimbo (pamberi petambo yakasara) uye kupera kwetambo ye optical inofanira kubatanidzwa kune chimiro nemagetsi akavimbika. kubatanidza kuburikidza neinofananidzwa yakatsaurirwa pasi waya.Iyo yakasara tambo furemu uye bhokisi rekubatanidza uye furemu inofanirwa kugadziriswa neinofananidzira inogadzirisa zvigadziriso uye insulating rubber.Iyo yakasara tambo inofanirwa kuiswa pane yakasara tambo rack ne θ1.6mm galvanized iron wire, uye mapoinzi ekusunga haafaniri kunge ari pasi pe4, uye yakasara tambo uye yakasara tambo rack iri mukubata kwakanaka.
2. Ground rekubatanidza bhokisi optical cable grounding nzira: Kuvimbika kwemagetsi kusungirirwa kunofanira kuitwa kune furemu kumusoro kwefuremu uye musoro wetambo yakasara kuburikidza nekufananidza dzakatsaurirwa tambo dzepasi.
3. Kutungamira kwetambo ye optical inofanira kuva yakarurama uye yakanaka.Isa chigadziriso chega chega 1.5m-2m kudzivirira kupokana pakati petambo yemaziso neshongwe.Iyo inotungamira-pasi optical tambo uye yemukati furemu yechiteshi inofanirwa kugadziriswa neyakafanana gadziriso zvigadziriso uye insulating rubber, uye chinhambwe chiri pakati peyakadzikiswa tambo yemaziso uye furemu haifanire kunge iri pasi pe20mm.
4. OPGW inofanira kunge yakabatanidzwa kune yepasi terminal yefuremu ine matching yakatsaurirwa wire yepasi, rutivi rweOPGW runofanira kubatanidzwa neparallel groove clamp, uye rutivi rwefuremu runofanira kubatanidzwa nemabhoti, uye hapana welding inobvumirwa.
5. Iyo inotungamira optical tambo inotungamirwa kubva mubhokisi rekubatanidza pane rack kusvika kune yakavigwa chikamu chetambo mugero inodzivirirwa neanopisa-dip galvanized simbi pombi, uye migumo miviri yepombi dzesimbi dzakanamwa nemoto usingadziviriri dhaka rekudzivirira mvura.Iyo pombi yesimbi inovimbika yakabatana kune yepasi grid muchiteshi.Iyo dhayamita yepombi yesimbi haifaniri kunge iri pasi pe50mm.
6. Iyo optical cable yakaiswa nefloor-standing cable box inotungamirwa kubva pafuremu kuenda kune yakavigwa chikamu chetambo mugero uye inodzivirirwa neinopisa-dip galvanized simbi pombi, uye insulated ne insulating sleeve, uye migumo miviri yakavharwa ne. madhaka asingapindi moto kuitira kudzivirira mvura.Iyo yakasara bhokisi bhokisi uye simbi pombi yakavimbika yakabatana kune yepasi grid muchiteshi.Iyo dhayamita yepombi yesimbi haifanirwe kuve isingasviki 50mm, dhayamita yesleeve insulating haifanire kunge iri pasi pe35mm, uye kubhenda kweredhiyo yepombi yesimbi haifanirwe kunge isingasviki ka15 dhayamita yepombi yesimbi.Yakavimbika insulation pakati pekubatanidza bhokisi, tambo reel uye cable bhokisi.
