Reducing Current Stress in Switchgear - ANSYS Advantage - V13 I1

In an emergency or when maintenance is required, high-voltage, high-current electric power must be quickly and safely disconnected. However, simply separating two contacts, as in a light switch, is not sufficient because high current makes the surrounding gas between the separating contacts conductive. This creates an electric arc over which the current continues to flow, and the current causes additional stresses on the associated busbar. Lucy Electric engineers estimated the electrodynamic forces and applied ANSYS Mechanical to optimize the shape, placement and durability of special splitter plates. Using simulation, the company increased the performance of switchgear designs quickly and economically and delivered superior, reliable energy products to market.
