Letoto la YTJLW10-720 Voltage Transformers
Ho nyatsa
Series YTJLW10-720 tatellano ea mekhahlelo, motlakase oa tatellano ea zero le transformer ea hajoale ke mofuta oa li-transformer tsa AC tse nang le lintlha tsa tekheniki tse lumellanang le thepa ea mantlha le ea bobeli ea fusion ea State Grid le ho latela T/CES 018-2018 "Distribution Network 10kV le 20kV AC Transformers Technical Conditions ". Li-voltage, hona joale le li-transformer tsa matla li hahiloe ka har'a sehlahisoa, se ka kopanngoang ka ho toba le mochine oa potoloho ho etsa mochine o bohlale oa "vacuum circuit breaker".
■ Capacitor e kholo e sebelisa matla a lekanang ho bokella motlakase, o nang le botsitso bo botle ba nako e telele le phihlelo ea nako e telele ea ts'ebetso ho li-grids tsa matla.
■ Phallo ea ka hare ho hanyetsa e nyenyane, e ka ikamahanyang le lithapo tse fapa-fapaneng, ea hlōla phoso e bakoang ke lithapo, 'me phoso ea ho fapanyetsana ha cable e ka tlaase ho 0.1%.
■ phetoho e nyane ea ho nepahala e anngoeng ke mocheso oa tikoloho, 'me phetoho e kholo ea phoso e ka tlase ho 0.5% sebakeng sa mocheso o felletseng oa -40 °C ~ 70 °C, e kopanang ka botlalo le tlhoko ea index ea phapano ea mocheso ea 3-level. transformer e boletsoeng.
■ e amohela matla a tsitsitseng a ho hanyetsa matla a matla le motlakase o fokolang oa matla a tlaase, botsitso bo botle ba tlhahiso le ho nepahala ho phahameng, 'me e kopana le maemo a ts'ebetso ea maemo ohle a mosebetsi.
