标准摘要
[中文适用范围]： IEC 61788 的这一部分描述了一种测试方法，用于确定短而直的 Ag 和/或 Ag 合金护套 Bi-2223 超导线在室温下两次弯曲后保留的临界电流，该超导线具有扁平或方形带的形状，其中包含单核或多核氧化物。导线可以用铜合金@不锈钢或镍合金带层压。该测试方法适用于临界电流小于 300 A 且 n 值大于 5 的超导体。确定保留临界电流的测试是在没有施加磁场的情况下进行的，将测试样本浸入液氮开放浴。 [外文原描述]： IEC 61788-24:2018 describes a test method for determining the retained critical current after double bending at room temperature of short and straight Ag- and/or Ag alloy-sheathed Bi-2223 superconducting wires that have the shape of a flat or square tape containing mono- or multicores of oxides. The wires can be laminated with copper alloy, stainless steel or Ni alloy tapes. The test method is intended for use with superconductors that have a critical current less than 300 A and an n-value larger than 5.
