Abstract
PURPOSE: To detect disconnection of the wire very effectively for public safety by detecting the arc light when it burns out.
CONSTITUTION: An optical fiber 2 is twisted into the clearance of the conductor 1. A severe arc discharge takes place when the wire burns out. At this moment, the optical fiber is left protruded into the arc at the burnt point. Even if there is little coupling at the section of the fiber, the optical fiber is able to transmit light detectable because the light source has a large intensity enough to do so. The light thus transmitted is detected by the light detector 5.
