摘　　要：SF6的温室效应是CO2的23 900倍,因此在高压电器中减少SF6气体用量,采用环境友好型气体作为绝缘介质已成为未来的发展趋势。随着技术的进步,特别是复合绝缘技术的发展,陆续出现了多种类型的72.5 kV环保型GIS。文中对当前国内外出现的72.5 kV不同类型的环保型GIS进行了分类归纳,并对典型的产品进行了介绍。同时对72.5 kV环保型GIS的关键技术——复合绝缘技术进行了研究和分析,探讨环保产品技术的发展方向与趋势。The greenhouse effect of sulfur hexafluoride（SF6）is 23 900 times that of the carbon dioxide（CO2）.Therefore,it has become the development trends in the future that to reduce the use of SF6 and to adopt environmentally friendly gas as the insulating medium in the high voltage apparatus.With the development of the technology,especially the development of the composite insulation technology,various types of 72.5 kV environmentally friendly gas-insulated metal-enclosed switchgear（GIS） have appeared.Different types of the 72.5 kV environmentally friendly GIS which appeared at home and abroad,have been classified in the paper,and typical products have been presented.Meanwhile,the key technology,the composite insulation technology,has been investigated in the paper.The development trends of the environmentally friendly products are also discussed.
