Ena kisi ni kena tara na laini ni taranisimisani e cake, E vuqa na tamata era cakacaka tiko ena veivakatorocaketaki era dau sotava na isema ni keveli ni livaliva kaukauwa. Nikua, Au vinakata me'u veivosakitaka vata kei iko na mataqali isema ni keveli ni livaliva kaukauwa kei na kena vakayagataki. iMatai, Me da veivosakitaka mada na cava High voltage power cable joints Era.
High Power Cable Joint
High-voltage power cable joints are used to connect keveli ni livaliva, oka kina na veisemati kei na veisemati ni veisemati. Me baleta na keveli ni livaliva vakasinaiti ena waiwai kei na keveli ni livaliva sitila seamless, E tiko talega na plug joints kei na veisema tale eso.
1. Veisemati raraba
E vakayagataki me semata e rua na keveli ni livaliva veivolekati.
Ena gaunisala ni keveli ni livaliva levu, me ikuri ni kena semati na conductor ni livaliva ni uto ni keveli me vakadeitaka na isema ni iyaya vakalivaliva, Na isema ni keveli ni livaliva vakasinaiti ena waiwai e dodonu me maroroya vinaka na iyatu ni waiwai ena uto. Ia baleta ni isema e caka ena liga ena vanua, e sega ni vinaka na kena ivakatagedegede ni cakacakataki. O koya gona, Na isema uto ena laini sa digitaki ena ruku ni ivakatagedegede ni riveting, kei na leqa ni vakatautauvatani ni lomanibai electrostatic ena isema ni uto ni pick duadua sa wali ena kena vakatorocaketaki na vavaku ni insulation kei na vakalailaitaka na kaukauwa ni lomanibai ni magnet ena cakacaka ni veisemati me vakadeitaka na cakacaka taqomaki ni isema. Vakararaba, The insulation of high-voltage power cables is wrapped around the top side of the winding insulation, kei na rua na yasa ni insulation ni winding e vakavurea e dua na cone ni lomaocaoca ni qele. The insulation shield is wrapped around the outside of the insulation to connect the two sides of the isasabai ni insulation ni keveli ni livaliva. Kei na batina e tautuba e tiko kina e dua na paipo sitila rarama e tautuba me insulation kei na itatarovi ni cagi me rawa ni vosota na kaukauwa ni keveli ni livaliva vakasinaiti ena waiwai.
2. Isema ni insulation
Insulation joints have the same structure and specifications as general joints. 110 ~ 225kV waiwai-vakasinaiti na keveli ni livaliva insulation joints e vakayagataki ena gaunisala levu kei na lekaleka ni keveli ni livaliva. Me rawa kina na veisemati ena yasa ruarua ni keveli ni livaliva na iyaya kaukamea sheath se iyaya kaukamea isasabai off layer kei na semi-conductivity layer ena iyaya ni livaliva break off, me vakarawarawataka na veisemati ni mataqali kauveilatai, vakalailaitaka na sheath e tautuba (se isasabai tani) Yavu ka kabasu.
3. Plug stop mataqali isema
The plug stop type joint is the most lacking stage of the electrical performance of oil-filled power cable fittings and is also the most complicated construction of the joint. Sa ikoya na idola me vakayagataki me undulate vakalevu cake mai na ivakatagedegede ni ivakatagedegede ni vakavakarau qaseqase reg pepa-insulated sala ni keveli ni livaliva, tagutuva na sala ni waiwai, me levea na insulation ni keveli ni livaliva cecere me mamaca, low-end power cable insulation vapor pressure exceed the standard value.
115kV dua-rumu plug stop positive intermediate joint, vakararaba vata kei na dua na epoxy resin rapa sega ni suasua sleeve me tawasei na iyatu waiwai ni rua na keveli ni livaliva.
225kV double chamber type plug stop positive intermediate joint, vata kei na rua na epoxy resin rapa waterproof casing me tawasei na iyatu waiwai ni rua na keveli ni livaliva, ena vica na iwasewase ni keveli ni livaliva plug stop tube ena yasa e cake ni dua na qara e tautuba, rua vata kei na lalaga e loma ni keveli ni livaliva kei na dua na interoperability ni iyatu waiwai e tautuba, e rua na yavu dregati.
4. Seamless steel pipe oil-filled power cable joints
E rua na mataqali isema ni keveli ni livaliva vakasinaiti ena waiwai: isema ni isema raraba kei na veimama ni veisemati.
Isema raraba, vakayagataki me baleta na caka ni keveli ni livaliva kei na buli ni isema lekaleka kei na balavu, Na kena ituvaki ni insulation e loma e tautauvata kei na isema ni keveli ni livaliva ni rua na roka, Na kena vale e dua na diameter levu cake vakalailai mai na pipeline ni keveli ni livaliva ni paipo kopa ni air-conditioning. Half plug stops joint for longer seamless steel pipe oil-filled power cable routes. Sa ikoya e dua na isema e tuvanaki me tarova na outflow ni vuqa na sleeves ni keveli ni livaliva ena gauna e yaco kina e dua na vakacalaka ni veitaqomaki ni veitaqomaki ni waiwai ka tuvanaki me tawasei na iwasewase ni waiwai e vakarautaki me rawa kina na waiwai ena iwasewase ruarua ni drodro mai na keveli ni livaliva insulation se bypass tube iyaya. In the seamless steel pipe of the joint and the seamless steel pipe of the power cable connection, Sa digitaki na yavu ni veivauci me tawasei kina na sala ni waiwai ni keveli ni livaliva.
