摘要： PURPOSE:To effectively detect the quench of a superconducting coil by forming a variable impedance element at part of a voltage divider, and variably providing the impedance of the element corresponding to the signal of a lower frequency band than a specific frequency band upon normal conduction transition of the signal contained in a potential difference signal. CONSTITUTION:When a quench is generated in a superconducting coil 11 in an AC exciting state of the coil 11, the impedance of the coil 11 is varied, and the output of an insulating amplifier 21 is abruptly increased. An intrinsic frequency signal component presented at the time of the quench is contained in the output of the amplifier 21, and cannot be passed through a low pass filter 22. Since a variable impedance element 18 does not respond, the output of the amplifier 21 is increased. On the other hand, a band pass filter 23 passes the intrinsic frequency signal component, the output of the filter 23 is increased. When it exceeds a detection level E, a cut-off command signal F is output from a breaker driving circuit 25 to open a breaker 14, thereby stopping power supply to the coil 11.

摘要： PURPOSE:To obtain a small thin magnetic element for power supply capable of detecting overcurrent with low loss, by installing a search coil to detect overcurrent passing through a plane coil, formed outside a magnetically soft layer of a plane inductor. CONSTITUTION:A spiral plane search coil 52, insulated by an insulating layer 2, is placed in proximity to either of poles outside the upper and lower magnetically soft layers 3 constituting a plane inductor. The search coil 52 is connected to a detector circuit. If the magnetically soft layer 3 operates in the proximity of saturation in its magnetization curve, a.c. magnetic flux beyond magnetic saturation leaks out of the magnetically soft layer 3; therefore, induced electromotive force is produced in the search coil 52. The magnitude of the induced electromotive force depends on that of the d.c. current passing through a plane coil 1, and thus overcurrent is detectable through the induced electromotive force of the search coil 52. If the d.c. current passing through the plane coil 1 is small, magnetic flux does not leak out of the magnetically soft layer 3, and no induced electromotive force is produced in the search coil 52. Therefore, no loss results.

摘要： PURPOSE:To detect the quenching of a superconducting coil irrespective of the fluctuation in frequency of an AC power source by a method wherein a signal of the reference time duration is obtained by a counter circuit, with which the specific pulse number outputted by a pulse transmitter is counted, and the pulse transmitter is synchronized with a voltage signal or a current signal. CONSTITUTION:A superconducting coil 1 is maintained in a normal superconducting state, and a normal AC current is made to flow on the superconducting coil. Besides, the time limit of reference generating circuits 16 and 17 at this time is set at the pi/2 of the frequency of an AC power source 6. When a normal AC current is flowing on the superconducting coil 1, the control end of a circuitbreaker driving circuit 7 is always maintained at the logical value of '0' as shown by the solid line of J as shown in the diagram. Also, when the superconducting coil is quenched for some reason in the state wherein an AC current is made to flow on the superconducting coil 1, the signal of '1' shown by the 'J' in the diagram is given to the control end of the circuit-breaker driving circuit 7. As a result, the circuit-breaker driving circuit 7 stops operation, a circuit breaker 4 is opened. Accordingly, the supply of current to the superconducting coil 1 is stopped, and the superconducting coil 1 is protected.
