Pagpapakilala sa Produkto
Ang 10kV Normal Pressure Sealed Air-Insulated Switchgear/Ring Main Unit (single circuit) ay gumagamit ng malinis at tuyo na hangin bilang insulating medium, kaya walang pangangailangan para sa SF₆ gas, nagbibigay ito ng kapaligiran-mahal na operasyon at mababang gastos sa pagpapanatili. Ang disenyo ng buong sealed structure nito ay nakakaprotektahan ito laban sa abo, moisture, at corrosive gases mula sa labas, at sumasang-ayon sa mga requirement ng installation sa iba't ibang environment. Ang single-circuit configuration nito ay simple at epektibo, may reliable short-circuit breaking at overload protection functions, at may flexible at stable operating mechanism na nag-aasure ng mabilis na response sa pagbubukas at pagsasara. Ang cabinet nito ay may compact structure at maliit na footprint, na nagpapadali ng installation sa narrow spaces. Ito ay malawakang ginagamit sa incoming line, feeder, at ring network connections ng 10kV power distribution systems sa urban distribution networks, industrial parks, residential communities, at iba pa, nagbibigay ng ligtas, matatag, at kapaligiran-mahal na operasyon para sa power distribution networks.
Normal pressure sealing: Walang risk ng pagbabalewala, nag-aasure ng excellent insulation performance.
Air insulation: Ang hangin ay hindi nangangailangan ng pagproseso. Sa pamamagitan ng improved processing techniques, selection ng high-grade materials, at optimized electric field design, ito ay sumasang-ayon sa demand para sa miniaturization.
Simple operating mechanism: May simple at stable structure, ang mechanical service life nito ay maaaring umabot sa 10,000 beses.
Miniaturization: Ang volume nito ay 1/5 ng KYN, katumbas ng volume ng conventional pressure-type, nagpapakita ng space savings.
Standardized expansion method: Nagpapadali ng on-site installation at nagbabawas ng oras ng brownout.
