High-voltage switchgear N2 series

metal-cladgas-insulatedvacuum

　　N2S/N2X High-voltage indoor gas-insulated metal-enclosed switchgear, designed and developed by the German senior experts, is a new generation of Medium-voltage C-GIS product integrating the excellent advantages of gas insulation and vacuum breaking technology. 　　* l Using environmental-friendly micro positive pressure gas N2 or its mixture with SF6 as insulating gas, to reduce the negative influence to the environment and the risk of gas leakage. 　　* Less space occupation. Each panel can save land by 40% ~ 73%. 　　* Modular gas tank structure, Suitable configuration schemes can be chosen based on the exact requirements to ensure the reliable and economic operation of switchgears. 　　* Maintenance free on primary circuit. All the high-voltage circuit are gas sealed and not influenced by the environment. 　　* Using VEG vacuum circuit breaker , with mechanical endurance up to 10,000 operations, so as to increase the performance and reliability of the equipment. The special vacuum interrupter design makes non-restrike possible for 40.5kV 800A capacitor bank switching. 　　* High-voltage gas tank is manufactured by 3mm stainless steel 3D 5-Axis laser welding, and checked by helium leakage detection. Ensure annual leakage rate less than 0.1% 　　* All operations are isolated from high voltage circuit, with safe and convenient operation. Both manual and motor operation are possible for circuit breaker and disconnector and suitable for remote intelligent control and operation especially. Reliable mechanical interlocking is equipped between circuit breaker and disconnector, complying with the requirments of "Five Unti-misoperation Interlocking".
