冷绝缘高温超导电缆用绝缘材料PPLP液氮浸渍击穿场强特性研究

Research on the Breakdown Stress Characteristic of PPLP Immerged in LN_2 Used in the Cold Dielectric Insulated HTS Cable

在进行冷绝缘(Cold Dielectric,简称CD绝缘)高温超导电缆的结构设计的研究中,其绝缘材料(PPLP)在液氮浸渍下的击穿场强特性是重要参数之一。通过测试PPLP在液氮浸渍的不同压力下的击穿场强,得到PPLP在液氮下的击穿场强特性。

The breakdown stress of the insulated material PPLP immerged in LN2 is one of the most important parameters when designing the structure of the CD insulated HTS cable. We obtained the characteristic of the breakdown stress of PPLP immerged in LN2 via testing the breakdown stresses of PPLP under different air pressures.
