Quenching Characteristics of Different Types of Superconducting Fault Current Limiting Modules

Abstract

Quenching characteristic is one of the most important characteristics of superconducting fault current limiters (SFCLs). Recently, the designs of SFCLs have been developing rapidly. Because of the influences of electrical inductance and heat dissipation, different types of SFCL could behave quite differently during quenching process. In this paper, the quenching characteristics of several different individual SFCL modules have been investigated. Special attention has been paid to the limited current and structural features between them. The elementary types of YBCO thin-film wires are solenoid and pancake. Different types of superconducting fault current limiting modules were connected in series to evaluate their advantages and disadvantages. Results in this paper could be helpful to optimize the designs of SFCLs in space utilization and energy efficiency.
