Abstract
Official abstract text for this publication.
A current-limiting device is a current-limiting device that uses a superconductor to perform a current-limiting operation, the current-limiting device including: a superconducting current-limiting element including the superconductor; a capacitor; a reactor; and a bypass switch. The series capacitor is connected in series to the superconducting current-limiting element. The current-limiting reactor is further connected in series to a series circuit including the superconducting current-limiting element and the series capacitor. The thyristor switch is connected in parallel to the series circuit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A current-limiting device that uses a superconductor to perform a current-limiting operation, the current-limiting device comprising: a superconducting current-limiting element including said superconductor; a capacitor connected in series to said superconducting current-limiting element; a reactor further connected in series to a series circuit including said superconducting current-limiting element and said capacitor; and a bypass switch connected in parallel to said series circuit, the current-limiting device being configured so that, in a normal state, the bypass switch is turned off and, in the case where overcurrent flows in the current-limiting device, the superconducting current-limiting element autonomously shifts to a normal conducting state and the bypass switch is turned on. 2. The current-limiting device according to claim 1 , wherein said bypass switch includes a thyristor switch. 3. The current-limiting device according to claim 1 , further comprising a suppression circuit connected in series to said bypass switch. 4. The current-limiting device according to claim 2 , further comprising a suppression circuit connected in series to said bypass switch.
