Abstract

La présente invention concerne l'ingénierie de l'énergie électrique et peut être appliquée pour surveiller l'état d'une ligne de transmission aérienne (OHL). Le résultat technique de l'invention est une fiabilité de surveillance plus élevée et une détection opportune d'un état inacceptable du conducteur dans une portée de ligne OHL surveillée. Le dispositif surveille l'état du conducteur de la ligne OHL (1) et comprend un bloc d'alimentation (2), un compteur de distance ultrasonique ou à laser (3), une unité (4) de transmission sans fil de données à un terminal distant et un bloc de traitement (5). Le bloc (5) est connecté au compteur de distance (3) et à l'unité (4). Le compteur de distance (3) est orienté vers la terre ou d'autres installations situées sous le conducteur (1). L'unité (4) est exécutée sous la forme d'un nœud d'interface entre le bloc (5) et un canal de téléphone cellulaire commun. Le bloc de traitement (5) est connecté à un indicateur de à un détecteur de courant (9) du conducteur (1). L'indicateur de signalisation (7) est exécuté sous la forme d'un émetteur-récepteur (10) de signaux haute fréquence codés qui est connecté par le biais d'une interface linéaire au conducteur (1) au moyen d'un nœud de connexion (11) et par le biais d'une interface numérique au bloc (5). Une telle conception pour l'indicateur de signalisation (7) permet d'équiper le dispositif d'un récepteur (12) pour des signaux de temps standard, par exemple un récepteur de signaux d'un système mondial de positionnement par satellite connecté au bloc de traitement (5).
