The N2S/N2X type high-voltage indoor gas insulated metal-enclosed switchgear is a new generation of medium-voltage C-GIS products developed under the leadership of senior German experts, combining the excellent performance of gas insulation with the advantages of vacuum interruption technology.
Product Features:
·The product design adopts micro-positive pressure insulation technology and laser welding of the gas tank to reduce the risk of gas leakage.
·Small footprint of the cabinet. Each cabinet saves 40%~73% of floor space.
·Modular gas tank structure allows selection of appropriate switch configuration schemes according to specific needs, ensuring reliability and economy of the switchgear.
·The primary circuit is truly maintenance-free. The high-voltage circuit is gas-sealed and unaffected by the external environment.
·Equipped with VEG type vacuum circuit breaker, with mechanical life up to 10,000 operations, improving equipment performance and reliability. The unique vacuum arc-extinguishing chamber design allows 800A capacitor switching at 40.5kV without restrike.
·The gas tank of the inflatable cabinet is processed by 3mm stainless steel sheet using three-dimensional five-axis laser welding and tested for leakage with helium leak detection equipment, ensuring an annual leakage rate of less than 0.05%.
·All operations are absolutely isolated from the high-voltage circuit, safe and convenient. The circuit breaker and disconnector are equipped with both manual and electric operation functions, especially suitable for remote intelligent control and operation. Reliable mechanical interlocking exists between the circuit breaker and disconnector, meeting the requirements of "five-proof interlocking".
·Silicone rubber connectors are used for busbar connections with plug-in installation. No gas handling is required on site during installation.
·Maximum rated current up to 4000A, safe and reliable.
·High-voltage components such as cable connectors, busbar connectors, and voltage transformers are all manufactured using German technology.
·This switchgear complies with standards such as GB/T3906, GB/T11022, DL/T404, and IEC62271-200.
