Matanho ekugadzirisa dambudziko rekugadzikana kwekupisa kweOPGW Optical cable
1. Wedzera chikamu chemheni conductor
Kana ikozvino inodarika kwete yakawanda, tambo yesimbi inogona kuwedzerwa nehukuru humwe.Kana ichipfuura yakawanda, inokurudzirwa kushandisa yakanaka conductor mheni yekudzivirira waya (yakadai sealuminium-clad simbi yakasungwa waya).Kazhinji, hazvidikanwi kushandura mutsara wose, chikamu chemutsara chete chinopinda nekubuda pachiteshi chemagetsi chinogona kuchinjwa, uye kureba kunotsanangurwa nekuverenga.
2. Kuzviparadzanisa nevamwe uye kuvhara kweOPGW optical tambo yekudzivirira mheni tambo yeinouya uye inobuda mutsetse
Iyo yakanyanya ikozvino mumutsara wekudzivirira mheni iri pamutsetse unouya uye unobuda.Kana tambo ye insulators ichiwedzerwa kumutsara wekudzivirira mheni pane iyi nhanho, yazvino haizokwanisi kupinda muchiteshi.Panguva ino, iyo yakawanda ikozvino inoitika mugiya rechipiri.Kunyangwe iyo yakazara pfupi-yedunhu ikozvino ichichinja zvishoma, kuramba kwepasi kunowedzera zvakanyanya, saka tambo yekudzivirira mheni ikozvino inoderera zvakanyanya.Nyaya mbiri dzinofanirwa kutariswa pakutora chiyero ichi.Imwe ndiyo kusarudzwa kwekupikiswa kwekumanikidzwa kwetambo ye insulator, uye imwe ndiyo yakakodzera kuenzaniswa kwepasi pasi peshongwe imwe neimwe kuderedza ikozvino mumutsara wekudzivirira mheni.
3. Shandisa shunt line kuderedza ikozvino yeOPGW optical cable
Mutengo weOPGW optical tambo wakakwira, uye hazvina mari kungo wedzera muchinjiko-chikamu cheOPGW optical tambo kutakura iyo pfupi-yedunhu ikozvino.Kana imwe tambo yekudzivirira mheni ichishandisa yakanaka conductor ine yakaderera impedance, inogona kutamba yakanaka shunt basa uye kuderedza ikozvino yeOPGW optical tambo.Kusarudzwa kwe shunt line kunofanira kusangana nemamiriro ezvinhu anotevera: iyo impedance yakaderera zvakakwana kuderedza kukosha kwezvino yeOPGW optical cable pasi pemutengo unobvumirwa;iyo shunt line pachayo inoda kuva nehombe yakakwana inobvumirwa ikozvino;iyo shunt line inofanira kusangana nezvinodiwa zvekudzivirira mheni.Iva nesimba rakakwana kuchengetedza chinhu.Kunyangwe kushorwa kweiyo shunt line kunogona kuderedzwa zvakanyanya, iyo inductive reactance inoderera zvishoma nezvishoma, saka basa reiyo shunt line rine imwe muganhu.Iyo shunt mutsara inogona kusarudzwa muzvikamu zvinoenderana nepfupi-yedunhu mamiriro azvino munzvimbo dzakasiyana dzemutsara, asi kunyanya kutariswa kunofanirwa kubhadharwa kune chokwadi chekuti kana iyo shunt mutsara ichichinja modhi, nekuti iyo shunt mutsara inova yakatetepa, yakawanda ikozvino. yakagoverwa kuOPGW optical cable, saka Ikozvino yeOPGW optical cable ichakurumidza kuwedzera yakawanda, saka kusarudzwa kwe shunt line kunoda kudzokorora kuverenga.
4. Sarudza zvirevo zviviri zveOPGW optical cables
Nekuda kwekuti tambo pfupi-yekutenderera yemitsara inopinda neinobuda yechiteshi chikuru, OPGW optical cables ine mahombe-sections anoshandiswa pano, nepo OPGW optical cables ine madiki-sections anoshandiswa kune inouya uye inobuda mitsetse kure. kubva pachiteshi.Ichi chiyero chinongoshanda kune mitsetse yakareba uye inofanira kuenzaniswa nehupfumi.Paunenge uchisarudza mhando mbiri dzeOPGW optical cables, maviri shunt mitsara inofanirwa kutariswa panguva imwe chete.Pamharadzano yemitsara miviri, kutarisisa kunofanirwa kubhadharwa kune shanduko kamwe kamwe mune yazvino yeOPGW optical cable uye mutsara wekudzivirira mheni.
5. Mutsara wekugovera pasi pevhu
Kana mitumbi yakawanda yekumisa ikashandiswa kubatanidza chigadziro chekugadzika cheterminal tower kune gidhi rekugadzika reiyo substation, chikamu chikuru cheiyo pfupi-circuit ikozvino ichapinda muchiteshi kubva pasi, ichidzikisa ikozvino yeinouya OPGW optical tambo uye. mheni conductor.Paunenge uchishandisa chiyero ichi, bvunza nedhipatimendi rekushandisa.
6. Parallel connection ye-multi-circuit mheni kudzivirira mitsara
Kana zvigadziriso zvekugadzika zveshongwe dzinoverengeka dzakabatanidzwa, iyo pfupi-yedunhu ikozvino inogona kuyerera ichipinda muchiteshi pamwe neakawanda-yedunhu mheni conductor, kuitira kuti imwe-yedunhu ikozvino idiki zvakanyanya.Kana kuchine dambudziko nekugadzikana kwekupisa kwetambo yekudzivirira mheni yegiya rechipiri, chigadziro chepasi chechipiri chigadziko shongwe chinogona kubatanidzwa, zvichingodaro.Nekudaro, zvinofanirwa kucherechedzwa kuti kana paine akawanda akabatana shongwe, dambudziko re relay zero-kutevedzana kuchengetedza inoda kudzidzwa.
7. Matanda anouya uye anobuda anoshandisa ADSS optical cables
Kana iyo OPGW optical tambo yakadzimwa, uye ADSS (yose-dielectric self-supporting) optical tambo inoshandiswa, iyo yakanyanya kupfupi-yedunhu ikozvino muOPGW optical tambo inogona kutariswa seyazvino inoyerera ichienda kune substation kana yechipiri base base tower. inokundikana, uye ikozvino yakakwira kupfuura iyo yekutanga base shongwe.Iyo pfupi yedunhu ikozvino idiki.Nokudaro, apo ADSS optical cable inoshandiswa pakupinda uye kubuda mutsara wekuvhara, iyo yakawanda yenguva pfupi-yekutenderera ikozvino inogona kuverengwa maererano nekapfupi-circuit ikozvino panguva yekukanganisa kwechipiri base tower panguva yekuongorora kwekushisa kweOPGW optical. tambo, kuitira kuti kugadzikana kwekupisa zvinodiwa zveOPGW optical tambo kuderedzwa zvakanyanya.
Kugadzikana kwekupisa kwe optical fiberoverhead composite pasi waya (OPGW)inofanira kunyatsotariswa mukugadzira uye kusarudzwa, uye matanho akasiyana-siyana anofanira kutorwa maererano nemaitiro chaiwo uye nzira chaiyo yeOPGW optical cable kudzivirira kukanganisa kunokonzerwa ne-single-phase grounding short-circuit current kune OPGW optical cable.kukuvadza, uye kugadzirisa kuvimbika kwekushanda kweOPGW optical cable.
