Abstract

PURPOSE:To suppress the generation of a surge voltage by applying a superconductive substance to the current-carrying part between the terminals at both sides, and then varying the cross-sectional area orthogonal to the direction the current flows as it goes forward in the direction the current flows, and at the same time cooling the current-carrying part to a temperature required for the superconductive substance in the current-carrying part to maintain its superconductive state. CONSTITUTION:The captioned device is constituted in such a manner that the current-carrying part 13 consisting of a superconductive substance is provided between the No.1 and No.2 terminals 1, 2 at both sides so as to be joined to these terminals 1, 2, and it is formed so that the cross-sectional area orthogonal to the current-carrying direction is varied, and at the same time, a prescribed cooling is performed by a cooling device 15. Thereby, the generation of a surge voltage, which is due to a sudden collapse in the superconductive state caused by overcurrent, can be suppressed, and at the same time, a current limiting device, which can be used a vast number of times and has a long life, can be obtained.
