る温度監視装置付断路器。 A light shielding plate is attached to the contact portion of the disconnector via a shape memory alloy whose one end is fixed, and the ends of the pair of optical fiber cables are made to face each other by the optical fiber support attached to the contact portion, and the light shielding plate is attached to the opposing portion. The light-shielding plate is arranged so that a plate is interposed therebetween, and the shape-memory alloy is deformed due to a temperature change at the contact portion, and the light-shielding plate moves forward and backward within the opposing portion of the optical fiber cable, thereby shielding the opposing portion of the optical fiber cable. A disconnector with a temperature monitoring device, characterized in that it is configured as follows.
