摘要(Abstract)：

电力设备绝缘介质的环保替代是近年来的热点问题，目前相关研究大都是针对环保绝缘材料本身性能的优化提升，对其实际应用在配电设备中可行性的关注相对较少。对此，首先对比了配电网台区关键设备用环保绝缘介质与传统绝缘介质的性能差异，接着采用环保绝缘介质设计制造了配电变压器、开关柜、电力电缆并评价了其电气性能，最后构建了基于环保型电力设备的配电网台区。结果表明，基于植物绝缘油、C4F7N/CO2（全氟异丁腈/二氧化碳）混合气体、聚丙烯电缆料制备的环保型电力设备在性能上与传统绝缘设备接近，可满足配电网电力设备的使用需求，验证了采用环保型绝缘介质生产的电力设备的实用性以及各设备间的匹配性，可为国内环保型配电网的应用推广提供参考。
It has been a popular topic recently that eco-friendly materials, in place of any other kinds, are used as insulation media for power equipment. So far, the relevant research mostly focuses on the performance optimization of eco-friendly insulating materials. However, little attention is paid to whether or not it can be applied to power distribution equipment. Therefore, performance differences between key equipment in transformation areas for which eco-friendly and traditional insulation media are used respectively. Then, eco-friendly insulation media are used to manufacture distribution transformers, switching cabinets, and power cables, and the electrical performance of the media is evaluated. Finally, a distribution transformer area based on eco-friendly power equipment is constructed.The results show that the eco-friendly power equipment prepared by using vegetable insulating oil, gas mixture C4F7N/CO2(perfluoroisobutyronitrile/carbon dioxide), and cable insulation material polypropylene is similar in performance to traditional equipment; it can meet the application demands of power equipment on distribution networks. The results also verify the practicability of power equipment made from eco-friendly insulating media and the compatibility between various equipment, which can provide a reference for implementing and promoting ecofriendly distribution networks in China.
