Paliwanag
Bilang ang unang manunulat sa sektor ng eco-friendly switchgear sa Tsina, nakaespesyalize kami sa R&D at paggawa ng walang SF₆ na switchgear sa loob ng ilang dekada. May mga core teknolohiya, itinatag namin ang mga pamantayan ng industriya. May ganap na independent end-to-end production chain, itinayo namin ang isang product matrix ng zero-emission at high-reliability na eco-friendly switchgear, kaya tayo ay isang tiwaling pinili para sa konstruksyon ng power grid.
Ang 34.5kV 35kV 36kV 38kV Maintenance-Free Gas-Insulated Switchgear (GIS) ay isang high-performance medium-voltage power distribution core device na ginawa para sa modernong smart grids at industrial power systems. Ito ay naglalaman ng maintenance-free design, advanced gas insulation technology, at stable power supply capabilities—na nag-aaddress sa mga pain points ng madalas na maintenance, environmental adaptability, at operational stability sa traditional 35kV switchgear.
Sa pag-adopt ng low-global-warming-potential (Low-GWP) na eco-friendly insulating gas at hermetic stainless-steel gas chambers, ito ay nag-eeliminate ng pangangailangan para sa regular na gas replenishment o component disassembly inspection. Bilang isang critical unit sa 35kV power transmission at distribution networks, malawak itong inaapply sa urban substations, industrial parks, new energy projects (tulad ng wind at solar farms), at large-scale commercial complexes. Ito ay nagse-secure ng continuous, reliable power supply para sa high-demand scenarios, habang kasabay nito ang global energy conservation at emission reduction goals, kaya ito ay isang sustainable solution para sa long-term grid operation.
Karakteristik
35kV-Level Maintenance-Free Operation:Ang hermetic gas chamber (na may leak rate ≤ 0.1%/year) at wear-resistant mechanical components ay nag-eeliminate ng routine maintenance tasks tulad ng gas refilling at part replacement. Ito ay bumabawas ng operation at maintenance (O&M) costs by over 60% kumpara sa traditional switchgear.
Superior Stable Power Supply Performance:Na-equipped ng vacuum interrupters para sa arc extinction at high-precision current/voltage transformers, ito ay epektibong nagsusulong ng resistance laban sa short-circuits, overvoltage, at voltage fluctuations. Ito ay nagpapanatili ng isang power supply reliability rate ng ≥ 99.98% kahit sa harsh environments (halimbawa, mataas na humidity, dust, o extreme temperatures).
Eco-Friendly & Safe Gas Insulation:Gumagamit ng Low-GWP environmental protection gas (compliant with IEC 61730 standards) upang iwasan ang greenhouse gas emissions; ang fully sealed structure ay nagpaprevent ng gas leakage at nagse-secure ng personnel safety. Ito rin ay may malakas na corrosion at pollution resistance, suitable para sa both indoor at outdoor installations.
Compact Design & Smart Integration:Ang modular at compact structure ay nagpapasave ng 40% ng installation space kumpara sa air-insulated switchgear, na fit para sa narrow areas tulad ng urban underground substations. Ito ay sumusuporta sa integration sa intelligent monitoring systems upang trackin ang gas pressure, temperature, at operating status sa real time, na nagbibigay-daan sa predictive fault management.
