摘要

To establish a selection criterion of high temperature superconducting (HTS) tapes for their possible application in superconducting fault current limiters (SFCLs), it is required to have high critical current density, high 'n' value, high normal state resistance, low AC losses, large heat transfer area, high thermal diffusivity and quick recovery against thermal instabilities for the HTS tapes. At present HTS tapes are categorized into two types namely Bi2223 based 1st generation (1G) HTS tape and YBCO based 2nd generation (2G) coated conductors (CCs). These 1G and 2G tapes are composite tapes. Hence, it is required to know their averaged material properties that can affect the performance of the SFCL during normal state operation. This paper deals with these issues along with DC characterization results to establish selection criteria of HTS tapes for SFCL applications.

Influence of Current Change Rate During DC Current Limitation on the Coated Conductor Degradation

Marek Mosat, Jan Souc, Michal Vojenciak, Mykola Solovyov, Marek Buran, Fedor Gomory

Summary: Reducing the amount of REBCO conductor in R-SCFCL by lowering the temperature of liquid Nitrogen from 77 K to 66 K can increase the critical current, but degradation of the superconductors at 66 K remains an issue that can be prevented by reducing the initial rate of current rise during the limitation event.

Critical Current Degradation in HTS Tapes for Superconducting Fault Current Limiter under Repeated Overcurrent

Sylwia Hajdasz, Adam Kempski, Krzysztof Solak, Maciej Marc, Jacek Rusinski, Pawel Szczesniak

Summary: Superconducting fault current limiters (SFCL) using high-temperature superconducting tapes of the second generation (HTS 2G) can replace traditional devices in power systems to limit short-circuit currents. The critical current of the HTS tape determines the activation of the SFCL and should remain constant to ensure proper cooperation with power system protection devices. The article presents research results on the degradation processes of 2G HTS tapes due to prospective short-circuit currents exceeding the critical current, including the decrease in critical current value and determination of limitation values of voltage drop that do not cause accelerated degradation processes.

Current Distribution in Superconducting Tapes During Fast Current Ramping Based on Modified Brandt's Method

Yi-Wen Chen, Xiao-Fen Li, Zhi-Jian Jin

Summary: In order to reduce the time and risk of sample damage during critical current characterization of long Coated Conductors (CC), a pulse current method was proposed. This study investigates the dynamic current distribution in the tape during pulse current ramping, utilizing a current-driven version of Brandt's method. A coil with 2000 turns was used in the experiment to improve the signal-to-noise ratio, and a scaling behavior was found for a simple but precise description of the effect of the current ramping rate on the measured critical current.

Hamoud Alafnan, Diaa-Eldin A. Mansour, Xiaoze Pei, Moanis Khedr, Mansoor Alturki, Abdullah Albaker, Ibrahim Alsaleh, Xianwu Zeng

Summary: Resistive-type superconducting fault current limiters (r-SFCLs) have gained significant interest for their self-action, fast response, and simple operation. However, overcurrent may damage the coils, necessitating the appropriate design of shunt resistors for protection. This study examines the thermoelectrical behavior of r-SFCL coils with different shunt resistor values, providing guidance for optimizing design parameters.

Bin Xiang, Ting Yu, Kun Li, Zhiyuan Liu, Yingsan Geng, Jianhua Wang

Summary: This paper proposes a novel superconducting current limiting type SF6 DC circuit breaker with bi-directional breaking function, which can effectively interrupt normal, overload, and short-circuit currents. The higher charging voltage and discharge current obtained by the quenching voltage of the superconducting coils charging method greatly improve the interruption ability, reducing the arcing time of short-circuit interruption significantly.

Critical current degradation and delamination crack observation of epoxy-coated REBCO superconducting tapes after thermal cycles in liquid nitrogen

Zhirong Yang, Peng Song, Mingzhi Guan, Feng Feng, Timing Qu

Summary: The study found that delamination and critical current degradation can occur in REBCO tapes after epoxy impregnation and thermal cycles, especially in samples with a free no-coating edge. Additional edge coating can help suppress the critical current degradation. The delamination cracks propagated within the REBCO layer and stopped at reaching the Silver/REBCO interface, suggesting that full epoxy coating on both tape surface and edges may reduce stress accumulation and prevent delamination cracks.

Summary: This report presents the development of reactively sputtered ultra-thin niobium nitride (NbN) films and their fabrication into patterned structures using 193 nm optical lithography on a 300 mm scale. The films showed a critical temperature (Tc) of around 9.5 K at a thickness of 50 nm, with less than 7% variation in room temperature sheet resistance. Damascene structures of NbN films with thicknesses ranging from 3 to 20 nm and widths ranging from 100 to 3000 nm, encapsulated by copper, were fabricated on a 300 mm Si wafer. The results highlight the potential of ultra-thin NbN films for various applications in quantum computing, photon detection, and superconducting circuits operating at GHz frequencies.
