Study of a SFCL Equipped with a Vacuum Interrupter Driven by Electromagnetic Repulsion Force for High-voltage SFCLs

open access: yesTEION KOGAKU (Journal of the Cryogenic Society of Japan), 2007
Using a high-temperature superconductor, we constructed and tested a model superconducting fault current limiter (SFCL). The superconductor and vacuum interrupter as the commutation switch were connected in parallel using a bypass coil. When the fault current flows in this equipment, the superconductor is quenched and the current is then transferred to

Experimental Tests of a Resistive SFCL Integrated With a Vacuum Interrupter

open access: yesIEEE Transactions on Applied Superconductivity, 2016
A resistive superconducting fault-current limiter (SFCL) has been developed using round magnesium diboride (MgB2) wire. The SFCL coil was wound using an interleaved coil arrangement to minimize the total coil inductance. The SFCL coil demonstrated reliable and repeatable current-limiting properties during testing.

Application Research of Several Improved Active Disturbance Rejection Control Methods for Superheated Steam Temperature System

open access: yesIET Smart Energy Systems, Volume 2, Issue 1, Page 49-61, March 2026.
A series of improved active disturbance rejection controller (ADRC) methods are proposed, and their parameter tuning processes are presented. They are comprehensively compared with regular proportional integral (PI) control and ADRC, and detailed superheated steam temperature (SST) simulations are carried out to verify their notably superior control ...

Das Infrarotspektrum von matrixisoliertem SFCl / Infrared Spectrum of Matrix Isolated SFCl

open access: yesZeitschrift für Naturforschung B, 1984
The new compound SFCl was obtained by UV photolysis of FC(O)SCl in rare gas matrix and by UV photolysis of Cl2/SF3SF in the gas phase. Isotopic substitution verifies the molecular identity. Eight frequencies from three isotropic molecules determine the force constants fSF = 4.30 and fscl = 2.90 102N/m.
