I-NSY/WSY/JSY 6/10KV 1-3 core 25-500mm² ngaphandle nasendlini high voltage cross-linked heat yekhebula itheminali eshwabenekayo kanye nokuhlangana okumaphakathi

Ikhanda letheminali yekhebula lamandla ashrinkable okushisa kanye nemikhiqizo yochungechunge oluhlangene olumaphakathi ihlanganisa ukuvikela amanzi, ukulawulwa kwengcindezi kanye nokwahlukanisa.Inezici ezinhle zikagesi kanye nemishini futhi ingasetshenziswa isikhathi eside ngaphansi kwezimo ezihlukahlukene ezinzima zemvelo.Inezinzuzo zesisindo sokukhanya nokufakwa okulula.Isetshenziswa kakhulu kumandla kagesi, i-petrochemical, i-metallurgy, ichweba likaloliwe kanye nezinkambu zokwakha.
Izinsiza zekhebula ezishwabene ukushisa, ngokuvamile ezaziwa ngokuthi amakhanda ekhebula ashwabene nokushisa, zisetshenziswa kakhulu ekuxhumekeni okumaphakathi namatheminali ezintambo ezixhumene kakhulu noma izintambo ezicwiliswe uwoyela ezinamaleveli kagesi angaphansi kuka-35KV kanye nezinsiza zekhebula ezishwabana ukushisa.Uma kuqhathaniswa nezesekeli zekhebula zendabuko, inezici zobukhulu obuncane, isisindo esilula, ukuphepha nokuthembeka, nokufaka okulula.Umkhiqizo uhambisana nezinga le-GB11033, izinga lokushisa lokusetshenziswa kwesikhathi eside lingu-55℃～105℃, impilo yokuguga ifinyelela eminyakeni engama-20, izinga lokuncipha kwe-radial ≥50%, izinga lokuncipha kwe-longitudinal lingaphansi kuka-5% , futhi izinga lokushisa lokuncipha lingu-110℃～140℃.
Izinto ezisetshenziswayo ngokuvamile zakhiwa inhlanganisela yezinto ezihlukahlukene ezifana ne-polyethylene, i-ethylene-vinyl acetate (EVA) nerabha ye-ethylene-propylene.
Lolu hlobo lomkhiqizo ngokuyinhloko lusebenzisa ithubhu lokucindezeleka ukubhekana nenkinga yokugxilisa ukucindezeleka kagesi.Okusho ukuthi, indlela yokulawula ipharamitha isetshenziselwa ukukhulula ukuhlushwa kokucindezeleka kwensimu kagesi.
Izinzuzo eziyinhloko isisindo esincane, ukufakwa kalula nokusebenza okuhle.intengo eshibhile.
Ishubhu yokucindezeleka iyishubhu elishwabene ukushisa elinemingcele ekhethekile kagesi enokumelana nevolumu emaphakathi (1010-1012Ω•cm) kanye nokungaguquguquki okuphezulu kwe-dielectric (20--25).Amapharamitha kagesi asetshenziselwa ukuphoqelela ukuphuma kwengcindezi lapho kuqhekeka i-insulation yekhebula nokuvikela.ibe ukusatshalaliswa okufanayo okuhambisana neshubhu lokucindezeleka.Lobu buchwepheshe bungasetshenziswa kuphela ku-35kV nangaphansi kwezinsiza zekhebula.Ngoba ithubhu yokucindezeleka izoshisa futhi ayikwazi ukusebenza lapho izinga le-voltage liphezulu.
Izinkinga zobuchwepheshe eziyinhloko ekusetshenzisweni kwayo yilezi: Ukuqinisekisa ukuthi amapharamitha kagesi weshubhu lokucindezeleka kufanele ahlangabezane namanani ashiwo amazinga ashiwo ngenhla, angasebenza.
Ngaphezu kwalokho, ukunakekelwa kufanele kukhokhwe ekugcwaliseni igebe lomoya ekuqhekekeni kwesendlalelo se-insulating semiconducting yekhebula nge-silicone grease ukususa igesi nokunciphisa ukukhishwa okuyingxenye.
Ikhebula elixhunywe ngokuphambano lizoncipha kakhulu phakathi nokusebenza ngenxa yokuphathwa kabi kokucindezeleka kwangaphakathi.Ngakho-ke, lapho ufaka izesekeli, qaphela ukugqagqana phakathi kweshubhu yokucindezeleka nesihlangu sokuvikela esingekho ngaphansi kuka-20mm ukuze uvimbele ishubhu lokucindezeleka nesihlangu sokuvikela ukuthi singafinyeleli ngesikhathi sokuncipha.
Ngenxa yokunwebeka okuphansi kwezesekeli ezincipha ukushisa, izikhala zomoya zingase zidalwe kusixhumi esibonakalayo ngesikhathi sokunwetshwa kwe-thermal kanye nokufinyela ngesikhathi sokusebenza, ngakho-ke ubuchwepheshe bokuvala uphawu bubalulekile ukuvimbela ukungena komswakama.
