LED-Based High-Voltage Lines Warning System

Öz

LED-based system, running with the current of high-voltage lines and converting the current flowing through the line into the light by using a toroid transformer, has been developed. The transformer’s primary winding is constituted by the high voltage power line. Toroidal core consists of two equal parts and the secondary windings are evenly placed on these two parts. The system is mounted on the high-voltage lines as a clamp. The secondary winding ends are connected in series by the connector on the clamp. LEDs are supplied by the voltage at the ends of secondary. Current flowing through highvoltage transmission lines is converted to voltage by the toroidal transformer and the light emitting LEDs are supplied with this voltage. The theory of the conversion of the current flowing through the line into the light is given. The system, running with the current of the line and converting the current into the light, has been developed. System has many application areas such as warning high voltage lines (warning winches to not hinder the high-voltage lines when working under the lines, warning planes to not touch the high-voltage lines), remote measurement of high-voltage line currents, and local illumination of the line area

Led Tabanlı Yüksek Gerilim Hatları İkaz Sistemi

Öz

LED tabanlı, yüksek gerilim hatlarından akım ile çalışan, hat üzerinden akan akımı bir toroid şeklinde transformatör ile akımı ışığa çeviren sistem geliştirilmiştir. Transformatörün primer sargısını yüksek gerilim hattı oluşturur. Toroid nüve iki bir birine eşit parçadan oluşur ve bu iki parça üzerinde sekonder sargıları eşit şekilde yerleştirilir. Sistem kelepçe şeklinde yüksek gerilim hattına monte edilir. Sekonder uçları ise kelepçe üzerindeki konektör bağlantısı ile seri bağlanır. Sekonder uçlarında oluşan gerilimle LED’ler beslenir. Yüksek gerilim hatlarında akan akım toroid transformatör ile gerilime çevrilir ve bu gerilim ile ışık veren LED’ler beslenir. Yüksek gerilim hatlarından akan akımı ışığa çevrilme teorisi verilmiştir. Hattan akan akımla beslenen, akımı ışığa çeviren sistem geliştirilmiştir. Sistem yüksek gerilim hatların ikazı (vinçlerin yüksek gerilim hatların altında çalışırken dikkat edilmesi ve zedelenmemesi, uçakların hatlara dokunmaması, yüksek gerilim hatlardan geçen akımların uzaktan ölçülmesi ve yüksek gerilim hat bölgesinin yerel aydınlatılması gibi uygulama alanları mevcuttur
