Abstract

We enhanced the performance of superconducting tapes during quenching by coating the tapes with various composites, with regards to the application of such coated systems in superconducting fault current limiters. In composition of the coating, we varied the type of epoxy matrix, the content of ceramic filler particles and the use of reinforcement in order to optimize the thermal and the mechanical stability of the coated tapes. By this way modified superconducting tapes were able to reduce the maximum temperature 170 °C of not modified superconducting tape to 55 °C during the quench with electric field up to 130 V m.

摘要

考虑到这种涂层系统在超导故障电流限制器中的应用，我们通过用各种复合材料涂覆超导带材来提高其在失超过程中的性能。在涂层的组成方面，我们改变了环氧基体的类型、陶瓷填料颗粒的含量以及增强材料的使用，以优化涂覆带材的热稳定性和机械稳定性。通过这种方式，改性超导带材在高达130 V/m电场的失超过程中，能够将未改性超导带材的最高温度从170℃降低到55℃。
