Current Limiting Characteristics of a Flux-lock type SFCL with Secondary Windings Connected to the Superconducting elements in parallel

초전도 소자 병렬 연결에 따른 자속구속형 한류기의 전류제한 특성

We investigated the quench characteristics of a superconducting element, two superconducting elements in order to increase the current capacity of flux lock type SFCL. The flux-lock type SFCL consisted of the transformer with a primary winding and a secondary winding connected in parallel, and the superconducting element was connected with secondary winding in series. The applied voltage at that time was 160 ${\sqrt{3}}$. We found that the parallel connection between the superconducting elements increased the power capacity and let quench characteristics improve through their mutual linkage.
