Next generation aircrafts will use more electrical power to reduce weight, fuel consumption, system complexity and greenhouse gas emissions. However, new failure modes and challenges arise related to the required voltage increase and consequent rise of electrical stress on wiring insulation materials, thus increasing the risk of electrical arc appearance. This work performs a critical and comprehensive review concerning arc tracking effects in wiring insulation systems, underlying mechanisms, role of materials and possible mitigation strategies, with a special focus on aircraft applications. To this end an evaluation of the scientific and technological state of the art is carried out from the analysis of theses, research articles, technical reports, international standards and white papers. This review paper also reports the limitations of existing insulation materials, standard test methods and mitigation approaches, while identifying the research needs to comply with the future demands of the aircraft industry.
下一代飞机将使用更多的电力来减轻重量、降低燃料消耗、简化系统复杂性并减少温室气体排放。然而,随着所需电压的增加以及电线绝缘材料上的电应力相应增加,新的故障模式和挑战随之出现,从而增加了电弧出现的风险。本工作针对飞机应用,对电线绝缘系统中电弧跟踪效应的潜在机制、材料的作用和可能的缓解策略进行了关键性和全面的综述。为此,从论文、研究文章、技术报告、国际标准和白皮书的分析中对科学和技术的现状进行了评估。本文综述报告了现有绝缘材料、标准测试方法和缓解措施的局限性,同时确定了研究需求,以满足未来飞机工业的需求。
