摘要：
This paper presents a new active electronic protection system that keeps a high temperature superconductor (HTS) coil that is in superconductive state from shifting into normal conduction state (quench). The coil is made of YBCO tape high temperature superconductor, with a critical temperature of 92 K. The superconducting coil is confined to a cryostat, which is vacuumed at about 0.001 mbar to minimize the heat transfer influx. The cryogenic agent, in which the coil is immersed, is liquid nitrogen, such that the working temperature of the HTS coil is about 77 K. The quench protection system is composed of an electronic quench protection and signal processing system, a power electronic module, and a stabilized voltage power supply, described in the paper.
