The toroidal magnetic field coil in the fusion device is
Generally, the inductance value is large, and it is very difficult to directly judge an interlayer short circuit inside the winding from waveform observation such as the voltage between the terminals of the toroidal magnetic field coil or the distortion of the excitation current. In addition, as a method for detecting interlayer short circuits, a method has been considered in which a variable frequency AC power source is connected between the terminals of an electric winding and the data is compared with data obtained from a healthy electric winding.
According to this method, the system has to be stopped every time a test is performed, and the operating rate of the system has to be reduced accordingly.

It is excited by an excitation power supply 3 connected through the energizing power source 3. A toroidal magnetic field coil terminal voltage detector 11 is installed between the terminals of the toroidal magnetic field coil, and is used to measure the voltage between the terminals of the toroidal magnetic field coil. A voltage detector 4 is connected between the terminals of each block coil 2, and its output signal is sent to an interlayer short circuit detection device 5, which is composed of a data storage device 6 and a voltage comparison circuit 7, through a measured value input circuit 12. sent to. The output circuit 13 generates a signal for interlocking protection when an interlayer short circuit occurs.

へ逆電圧を誘導するためである。 In this configuration, a computer simulation will be performed assuming that an interlayer short circuit occurs inside the winding of the toroidal magnetic field coil. Figure 2 shows an example of the simulation results, showing the voltage detector 11 between the terminals of the toroidal magnetic field coil.
The voltage between the terminals of the toroidal magnetic field coil detected at 8
and block coil 2 detected by voltage detector 4.
The terminal-to-terminal voltage 9 is shown. Although the voltage value 8 between the terminals of the toroidal magnetic field coil and the voltage value 9 between the terminals of the block coil 2 are different in order, the two quantities are shown in the same graph in FIG. 2 for convenience.
From this figure, it can be seen that a spike-like voltage is generated in the block coil 2 at the time when an interlayer short circuit occurs. This means that the rate of change in current in the one-turn coil that caused the interlayer short circuit is several hundred kiloamperes/
This is very large, on the order of seconds, and as a reaction to this, a reverse voltage is induced in the remaining windings in the block coil 2 where the interlayer short circuit has occurred.

である。 Therefore, the voltage 9 between the terminals of each block coil 2 is constantly observed, and the voltage value 9 between the terminals of the block coil 2 and the voltage value set in the data storage device are successively compared by the voltage comparison circuit 7. By doing so, it is possible to detect interlayer short circuits in the toroidal magnetic field coil without stopping the system.
