绝缘材料和绝缘系统的设计已经获得越来越多的关注，因为越来越多的电机倾向于在各种应用的恶劣环境中运行。恶劣环境包括高温、潮湿、侵蚀、低气压等。本文讨论了电机绝缘系统的最新进展。绝缘测试以及测试标准，已用于评估绝缘系统和检测绝缘故障将被讨论。绝缘材料用于广泛的工业应用，如风力发电机，航空航天混合动力/电力传动系统，和水轮发电机已经总结。对于新兴的高空、高压航天应用，将讨论局部放电及其对绝缘系统的影响。最后，展望了具有优异导热性和介电强度的高分子纳米复合材料的发展前景。
Insulating materials and insulation systems design have been gaining more attentions as more electrical machines tend to operate in harsher environments for various applications. Harsh environments include high temperature, humidity, erosion, low air pressure, etc. This paper discusses recent advances in insulation systems for electrical machines. Insulation tests as well as test standards that have been used to evaluate insulation systems and detect insulation failures will be discussed. Insulating materials used for a wide range of industrial applications such as wind turbine generators, aerospace hybrid/electric powertrain, and hydro generators have been summarized. For the emerging high-altitude, highvoltage aerospace applications, partial discharge and its impact on insulation systems will be discussed. Finally, polymer nanocomposite materials with excellent thermal conductivity and dielectric strength are highlighted as an outlook.
