Pagpapakilala sa Produkto
Ang 10kV Normal Pressure Sealed Air-Insulated Switchgear/Ring Main Unit (single circuit) gamit ang malinis at tuyo na hangin bilang insulasyon, walang pangangailangan para sa SF₆ gas, nagpapahusay ng kalikasan at mababang gastos sa operasyon at pagmamanage. Ang disenyo nito na buong sealed ay nakakatulong upang makaiwas sa abo, tubig at mga korosibong gas mula sa labas, na siyang sumasang-ayon sa iba't ibang kapaligiran ng pag-install. Ang single-circuit configuration nito ay maikli at epektibo, may tiyak na short-circuit breaking at overload protection functions, at flexible at stable operating mechanism na nagbibigay ng mabilis na response sa pagbubukas at pagsasara. Ang kabinet nito ay may kompak na estruktura at maliit na footprint, na nagpapadali sa pag-install 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., nagbibigay ng ligtas, matatag at environmental-friendly operation guarantee para sa power distribution networks.
Normal pressure sealing: Walang risk ng pagdami, nagbibigay ng excellent insulation performance.
Air insulation: Ang hangin ay hindi nangangailangan ng treatment. 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 ones, nakakatipid ng space.
Standardized expansion method: Nagpapadali sa on-site installation at nagbabawas ng oras ng brownout.
