Description
Current leads that utilize high-temperature superconductors (HTSS) to deliver power to devices operating at liquid helium temperature have the potential to reduce refrigeration requirements to levels significantly below those achievable with conventional leads. As part of the US Department of Energy`s Superconductivity Technology Program, Argonne National Laboratory and two industrial partners are developing HTS current leads for application to superconducting magnetic energy storage (SMES) systems. Superconductivity, Inc. (SI) is a supplier of micro-SMES systems for power-quality applications. A typical SI SMES system has an 0.3-kWh energy capacity and operates at currents up to 1.2 k.A. The Babcock & Wilcox Company (B&W) is engaged in a project to design, build, and demonstrate a midsized SMES system. The B&W system has an 0.5-MWh energy capacity and operates at currents up to 16 kA. Details of the lead designs. including materials, configuration and performance predictions. are presented.
