Product Introduction
Ang 10kV Normal Pressure Sealed Air-Insulated Switchgear/Ring Main Unit (single circuit) ay gumagamit ng malinis at matarong hangin bilang insulating medium, na nagwawala ng pangangailangan para sa SF₆ gas, kaya ito ay mas maganda para sa kapaligiran at may mababang gastos sa operasyon at pagmamanage. Ang disenyo nito na fully sealed structure ay nakakatulong upang mabawasan ang epekto ng abo, tubig, at mga corrosive gases mula sa labas, na siyang tumutugon sa mga requirement ng installation sa iba't ibang environment. Ang single-circuit configuration nito ay simple at efficient, na may reliable short-circuit breaking at overload protection functions, kasama ang flexible at stable operating mechanism na nagbibigay ng mabilis na pagbubukas at pagsasara. Ang cabinet nito ay may compact structure at maliit na footprint, na nagpapadali ng installation sa mga 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, atbp., na nagbibigay ng safe, stable, at environmentally friendly operation guarantee para sa power distribution networks.
Normal pressure sealing: Walang risk ng leakage, na nagse-secure ng excellent insulation performance.
Air insulation: Ang gas ay hindi nangangailangan ng treatment. Sa pamamagitan ng improved processing techniques, selection ng high-grade materials, at optimized electric field design, ito ay tumutugon 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, na katumbas ng volume ng conventional pressure-type ones, na nagbabawas ng space.
Standardized expansion method: Nagpapadali ng on-site installation at nagbabawas ng oras ng power outage.
