I 06 07 Gas Insulated Switchgear Mechanical Performance Analysis To maximize the optimum mechanical performance of the conductor, enclosure, and controller of the GIS, values (mass, shape, stress, transformation, etc) of all parts of the GIS are precisely analyzed using the structure analysis programs and three-dimensional design. Analysis with NASTRAN/PATRAN Hydraulic main valve block Busduct support Three-Dimensional Design & Assembly Solid Edge, the latest three-dimensional design tool, is used for basic GIS design to assembling parts in order to minimize any possible design errors. It is also used to model the final installation so that the installation site is optimized by the assembled parts. Seismic & Vibration To verify the seismic and vibration at the design stage, the latest seismic and vibration analysis tools, which consider all loads resulting from gravity (both the vertical load and the wind load), have been used for ensuring overall structural safety.
Compartments Circuit Breaker Hyosung’s circuit breaker uses superior arc quenching performance and the insulation characteristics of the SF6 gas and adopts the puffer-type, which has a simple operation principle and structure. With the double trip coil, it guarantees reliable circuit breaking and its few parts allow for simple maintenance. Configuration of Circuit Breaker Configuration of Interruptor Disconnecting Switch Disconnecting switch is a device used to segment the charge current section partitioned by the circuit breaker. It is operated by an electric motor; however, it can be manually operated for maintenance tests. In addition, the user can check the switch status since the switch status display is connected to the control shaft in the control box. Assembly of Disconnecting Switch & Earthing Switches for GIS
