ABSTRACT:
An electric power distribution switching device including a detector for detecting accidental arcs in the electric power distribution switching device, which detector includes at least one waveguide in which the light generated by the arc and reaching it via its casing is used as a triggering or warning criterion. The detector can include a support rod, a waveguide wound helically around the support rod, and two plug connectors fitted at the ends of the support rod. The detector also includes a heat-shrink sleeve which is permeable to light and UV radiation. The heat-shrink sleeve is fitted over the support rod, the waveguide and the plug connectors. A detector configured in this manner can prevent damage to the detector during installation or fitting in the switching equipment.
