QUENCH Electromagnetic Software Tool Supports Sumitomo DI-BSSCO

The QUENCH electromagnetic software tool, from Cobham Technical Services, now features a library containing manufacturer-supplied material characterization data for Sumitomo Electric’s DI-BSSCO bismuth-based superconducting wire. QUENCH is a tool for modeling the quenching process in superconducting materials. The QUENCH tool for modeling the superconducting quenching process is available as part of Cobham’s Opera CAE software suite for low frequency electromagnetic simulation.

A quenching process is when a wire turns from a superconducting to resistive state. QUENCH has become the standard simulation tool for superconducting equipment, because its multi-physics modeling couples the electromagnetic and thermal modeling processes. Results can be post-processed to provide users with clear views and analyses of the potentially damaging effects of quench propagation as the wire heats up and becomes resistive, including displays of the voltages between coil layers, temperature gradients, and so on. This analysis helps engineers to quickly find the optimal design, and incorporate protection circuitry.

The QUENCH tool and library simplify the design and prototyping stages of applying high temperature superconductors (HTS). HTS-based solutions are being considered for electricity transmission and distribution infrastructure, hydroelectric and wind turbine generators, electric motor propulsion systems for ships, and high performance magnets.

Sumitomo Electric was the first company to produce long bismuth-based superconducting wire, which is a material that has become an industry standard and is considered to be the major candidate for commercial HTS applications. Sumitomo’s DI-BSSCO bismuth-based superconducting wire is made of bismuth-strontium-calcium-copper-oxygen and operates at temperatures up to 110 K.
