Optical system for monitoring the integrity of the drivers of power transmission lines with concomitant transmission of telecommunication signals in broadband.

摘要

The present invention patent application in distribution systems and electric power transmission systems, notably using conductors of transmission and distribution of electric energy.The optical system for monitoring integrity of conductors of power transmission lines with concomitant transmission of telecommunication signals comprises a broadband terminal signal transmission multiplexed wavelength WDM - that transmits up to? N? The wavelengths of the form unidirectional or bidirectional WDM to a terminal B (6) using as a means of transmiA fiber optic pressure contained within an OPGW optical cable (optical ground wire) or (air dielectric self-supporting) or of another type.Part of the wavelengths transmitted are derived by a coupling system for a fiber optic cable contained inside a conductive type OPPC (optical phase conductor), for example, in a section critical of LT (transmission line) which interconnects a substation D And energy with a power substation.The power cable conductor with fiber optics is part of the transmission line, however the transmission line only contains energy conductors with optical fiber installed in a given sentence critic to be defined.The signals in the wavelength thereof for optical fiber are reflected by reflective devices, so-called signals after reflection, return to the terminal WDM - where they are detected and converted to electrical signals and sent to the supervision unit which identifies the situation D. The fiber.And in the case of rupture of the optical fiber sends a signal to the relevant so as to inhibit automatic reconnection of power transmission by Lt.
