초록

This paper describes the conductor temperature and tensile load analysis of invar by flame exposure on STACIR(Super Thermal-resistance Aluminium-alloy Conductors Reinforced) overhead transmission line based on real fault phenomena. Firstly, short-circuit fault by flame exposure is analysed by EMTP/ATP simulation, then the cutting causes of Al layer are also discussed. And then, the conductor temperature is calculated based on IEC 60949 according to 3 kinds of materials including invar, Al conductor and ACSR when same load current respectively flows in 3 kinds of material, they are compared each other. Finally, the tensile load tests are performed with various samples including new invar, used invar for a long time and invar exposed flame.
