Kana tichitaura nezvekuzvitsigira kuisirwa kwemuchadenga, imwe yeanonyanya kunyorera kufambisa-daro kureba kuisa tambo dzefiber optic mushongwe dzemagetsi akakwira.
Zvimiro zvazvino zve-high-voltage zvinotumira mhando inoyevedza yekuisa nekuti inoderedza mari muzvivakwa zvinodiwa kugadzira mafiber optic links matsva, aya ari, akatovakwa-mukati.Asi mitsara mushongwe dzepamusoro-voltage dzinowanzo kuunza matambudziko makuru, anowanzo onekwa mumidziyo inobata yakakwirira magetsi emagetsi: iyo yekutevera maitiro uye corona discharge.
Chii chinonzi tracking effect?
Iyo inozivikanwawo muindasitiri seyakaoma banding kana yemagetsi arborescence, iyo yekutevera mhedzisiro inoreva kuparadzwa kwe dielectric ye insulating material, isingadzokerike inotorwa kubva muchikamu chemagetsi chinobuda chinoenda mukati kana pamusoro pechinhu che dielectric kana chaiswa pakakwirira. -voltage magetsi kunetseka.
Corona kubuda
Imwe njodzi yekuti tambo dzemuchadenga dzinozvitsigira dzinomhanya kana dzaiswa mushongwe dzakakwirira-voltage ndeye corona effect, inozivikanwawo secorona discharge, inotsanangurwa seionization yegasi rakatenderedza conductor akachaja.Kuiswa kwefiber optic cable, gasi ndiyo mhepo pachayo, iyo inotenderedza tambo yekufambisa.
Iyo corona mhedzisiro iripo mune ese maturusi uye zvimisikidzo zvinoshanda kana kuitisa magetsi.Muhupenyu hwedu hwemazuva ese, izvi hazviwanzo kuoneka uye hazvitikanganisa zvakanyanya nekuda kwemagetsi uye kugona kwemagetsi kwatinowanzo kushandisa.Nekudaro, mumashongwe akakwira-voltage, mavoltages anofamba pamitsetse yavo akakwira zvakanyanya (kubva pa66 kV kusvika 115 kV), zvichiita kuti corona effect inogadzirwa nemakondakita aya ive yakafara zvakanyanya.
Kana yaiswa kunze kwekunze, tambo dzinopesvedzerwa nezvinhu zviviri zvakakosha: hunyoro hwemhepo uye indekisi yekusvibisa kwezvakatipoteredza.Nehunyoro huzhinji, mvura yakawanda inoputika pamusoro petambo;uye nekunyanya kusvibiswa kwezvakatipoteredza, zvidimbu zvakawanda (guruva, heavy metals, minerals) zvichavharirwa mumadonhwe emvura akaumbwa.
Aya madonhwe ane tsvina anove conductive, kana iyo corona mhedzisiro yeyakakwira-voltage mutsara inosvika madonhwe maviri ari padyo zvakaringana kune mumwe nemumwe, arc yemagetsi inogadzirwa, inogadzira kupisa pakati pavo uye inosvibisa jekete zvinhu zvetambo.
Cable dziviriro uye anti-kutevera zvinhu
Zvinokurudzirwa kushandisa anti-tracking zvinhu paunenge uchiisaADSS faibha optic tambospedyo nemidziyo uye zvivakwa zvinobata masimba emagetsi e12 kV kusvika ku25 kV.Izvi zvinogona kuramba zvirinani mhedzisiro yekubuda kwemagetsi, kudzikisira mhedzisiro yeionization, kudziyisa, uye kuderedzwa kwetambo.
Anti-kutevera zvinhu zvakakamurwa kuita maviri akakura kupatsanura, kirasi A zvinhu uye kirasi B zvinhu:
Zvishandiso zveKirasi A
Zvishandiso zveKirasi A ndizvo zvinosangana nemaitiro ekupikisa zvichibva pane yakashandiswa voltage uye kusvibiswa index yakaedzwa pasi peIEEE P1222 2011 standard, izvi zvinoonekwa se "standard" pamusika.
Kirasi B zvinhu
Zvishandiso zveKirasi B ndeizvo zvisiri pasi peiyo chiyero, izvi hazvireve kuti zvinhu izvi hazvishande kudzivirira kubva kune yekutevera maitiro, asi kuti, zvinotongwa nemaparamita kana akakosha mamiriro anotsanangurwa nemugadziri, kungave kwekushandisa kwakakosha. kana zvimwe zvinoomesesa zvinodiwa, kirasi iyi inogona kutsanangurwa se "tsika".
Mazano eADSS tambokuiswa mu high-voltage tower
Kugadzirira ndicho chinhu chikuru.Izvo zvinodiwa kuti utarise indekisi yekusvibisa uye magetsi ekuisa kana inozvitsigira yefiber optic tambo yakaiswa pane refu-kure, yakakwirira-voltage tower.Chero bedzi isu tiri mukati memiganhu yakagadzwa neIEEE P1222-2011 chiyero, tinogona kushandisa kirasi A zvinhu, iyo inowanikwa zvakanyanya mumusika;kune akanyanya kuomarara mamiriro ezvakatipoteredza kana akakwira voltages, zvinodikanwa kushandisa kirasi B zvinhu.
Bata yako mugadziri wetambo kuti uone rudzi rwezvinhu zvinogona kushandiswa kuchengetedza zvirinani kuperera kwetambo mukugadzika kwako, kusangana nemamiriro ayo tambo ichaburitswa.
