Abstract
PURPOSE:To detect the abnormality in the junction part by sensing the variation in intensity of light passing optical fiber embedded in the vicinity of a junction plane of a current conducting coil conductor which is divided into at least two parts. CONSTITUTION:When the coil, wherein a high voltage, large current is flowed, is divided into at least two parts and joined at the time of fabrication, and optical fiber accommodating groove 21 is provided through the junction plane 2 of a conductor 1, and the optical fiber 20 is embedded. When the temperature of the optical fiber is increased, the transmittance of the light is decreased. In this way, the light from a light source is measured by a receiving part during the operation, and the increase in the temperature due to the abnormality of the junction part can be monitored. If the optical fiber 20 is divided at the junction plane 2 so that the divided parts face each other and embedded, the displacement of the conductor at the junction part can be detected. If the optical fiber is directly connected to photoelectric converting part from the light source, and its output and the output of the optical fiber 20 are compared, more accurate monitoring can be performed. The device can be suitably employed for troidal coils or poloidal coils in a torus type nuclear fusion device.
