摘要
It is important that study on cryogenic electrical insulation design to develop the cold dielectric (CD) type high temperature superconducting (HTS) cable because the cable is operated under the high-voltage environment in cryogenic temperature. Therefore, this paper describes a design method for the electrical insulation layer of the CD type HTS cable adopting the partial discharge (PD)- free design under ac stress, based on the experimental results such a partial discharge inception stress (PDIE) and V-t characteristics, and an impulse breakdown strength of liquid nitrogen (LN2)/laminated polypropylene paper (LPP) composite insulation system in which the mini-model cable is immersed into pressurized LN2.
