在德国10 kV/10 MVA超导故障限流器项目CURL 10中，一个非常有前途的选择是熔铸处理（MCP-）BSCCO 2212块体材料。通过将管状样品切割成双线线圈并串联接触，可以轻松实现所需的长长度（每相160 m）。在T=65 K的工作温度下，临界电流密度接近4000 A/cm/sup 2/，极限电压达到E/sub p/=0.5 V/cm。本文介绍了超导元件的设计、制造和测试。特别是一个合适的电分流的发展和表征的重点。最后，在各种限制条件下，对成品组件进行电气均匀性表征。可以确认单个组件均满足项目中定义的所有要求。
A very promising option within the German 10 kV/10 MVA superconducting fault current limiter project CURL 10 is melt cast processed (MCP-) BSCCO 2212 bulk material. With tube shaped samples cut to bifilar coils and contacted in series, the required long lengths (160 m per phase) can easily be achieved. At the operating temperature of T=65 K the critical current density is near 4000 A/cm/sup 2/ and the voltage under limiting conditions reaches E/sub p/=0.5 V/cm. The contribution describes the design, manufacturing and testing of the superconducting components. In particular the development and characterization of a suitable electrical shunt is focused. Finally the finished components are characterized with respect to electrical homogeneity and under various limiting conditions. It could be confirmed that the single components each meet all the requirements defined within the project.
