摘要
Aeronautical cables are widely used as the electric transmission lines of energy systems for aviation equipment and account for a high proportion. Because of the special environment and long-distance of cable laying, it is difficult to detect and repair the cables frequently. The insulation status cannot be monitored in time. Inevitable losses occur in case of cables’ failure in an aircraft. With the development of more-electric-aircraft (MEA) or all-electric-aircraft (AEA), it is necessary to satisfy the higher requirements on cable insulation performance and structural design for the aeronautical electric system. For this purpose, this paper has reviewed the latest research concerns from five aspects, including insulation properties, conductivity, insulation aging, partial discharge detection, aviation arc detection and diagnosis. In addition, it has summarized the strategies and schemes for insulation defect detection, aging features, multi-parameter characterization and optimization for aeronautical cables. Since MEA are trending towards high voltage level, large power and low carbon emission, the main threats and challenges of aeronautical cable insulation are summarized. The review is expected to provide a significant reference for the optimization and improvement of aeronautical cables and even MEA. © 2023 Chinese Society for Electrical Engineering.
