The invention relates to a detector for accidental arcs in electric power distribution switching equipments in which the detector consists of at least one light guide in which the light generated by the arc and reaching it via its casing is used as a triggering or warning factor. The detector is intended to permit the break-protected fitting of the light guide in a switching equipment. This is achieved in that the detector (1) consists of a support rod (2), a light guide (3) wound helically around the support rod (2) and two plug connectors (4) fitted at the ends of the support rod for connection to opto-electronic components, and the detector (1) also consists of a light and u/v radiation-permeable heat-shrink sleeve (5) fitted over the support rod (2), the light guide (3) and the plug connectors (4). |
