Abstract

PURPOSE:To obtain the economical non-contact breaker of a miniature type, by connecting a plurality of the series connecting units of superconducting current-limiting wires and semiconductor breaking sections in parallel with each other. CONSTITUTION:Superconducting current-limiting wires 2a, 2b, 2c and semiconductor breaking sections 1a, 1b, 1c are respectively connected in series, and the series-connected ones are connected in parallel with each other to compose circuits. At the time of the generation of an accident, current to a circuit A is interrupted, and when current is fed to a circuit D, then a magnetic field is worked on the superconducting current-limiting wire 2a or a temperature is heightened, and the wire 2a is turned normally conductive and the current is limited, and after that, breaking command is issued to the semiconductor breaking section 1a. After that, the semiconductor breaking section 1b of the circuit U is closed. The superconducting current-limiting wire 26 of the circuit D is kept in a superconducting state, and so the circuit is quickly closed again.
