Experimental Investigation of the Subcooled Liquid Nitrogen for Resistive Superconducting Fault Current Limiter
저항형 한류기 운전조건에서의 과냉각 액체질소 특성 실험
Abstract
A subcooled liquid nitrogen cryostat is required for the cooling of a 6.6 ㎸, 200 A resistive type superconductive fault current limiter (SFCL). To help understand and design an appropriate cryostat for SFCL a prototype cryostat was fabricated and tested. Several states of subcooled liquid nitrogen were obtained by using cryocooler and helium gas. The temperature was uniformly distributed inside the liquid nitrogen vessel within the range of 0.4 K proving the effectiveness of the conduction cylinder.
