Gap insulation state assessment and early warning method for carbon fiber composite core conductor

Abstract

In today’s fast-progressing economy and society, demands on the quality of electricity are increasing, and accordingly, the size of the electricity supply system is growing. The structure is becoming more and more complex; if the power system fails, it will lead to large-scale blackout accidents. Especially for carbon fiber composite core wires made of expensive carbon fiber materials, it will cause greater economic losses and serious social impacts. This article proposes a gap insulation state evaluation model for carbon fiber composite core wires, including considering altitude factors. Comparison of minimum safe clearance distance between carbon fiber composite core wire and steel core aluminum stranded wire through calculation of wind deflection angle. It can achieve online assessment of the risk of conductor wind-induced flashover. In addition, the practicality and functionality of this model have been verified through real-world examples.
