Abstract

PURPOSE:To exactly detect an accident, by detecting the voltage of a superconducting section, and by issuing breaking command to a breaking section with specified voltage. CONSTITUTION:To a superconducting wire 1, a breaking section 2 is connected, and the partial or the whole voltage of the superconducting wire 1 is measured by a voltmeter 3. When the superconducting wire 1 is turned normally conductive, then voltage is boosted and detected, and to the breaking section 2, command for breaking a circuit is issued.
