Abstract

The recent activity on electrical insulation and its ageing aspect in gas-insulated switchgear (GIS) as well as future trends are described in this paper. Present status of research shows that although there are a lot of reports on computer based partial discharge measurement, there are few on the intrinsic phenomena of fundamental ageing characteristics. These data will be indispensable for extending new concepts of GIS insulation. As an example, it is pointed out that research on electric stress enhancement in solid materials is important, in particular, in relation to life-estimation and life-control techniques as well as with making more compact GIS. For this purpose, the introduction of consistent concepts, from the development/design stages to the testing/operation stages, of GIS is needed. This concept would include sensor integrated GIS, failure-prediction techniques and stress-controlled life-estimation systems. These proposals are described in this paper from the manufacturer's viewpoint.<>

从制造商的角度分析GIS电气绝缘老化特性的最新动态和未来趋势

本文介绍了气体绝缘开关设备在电气绝缘方面的最新进展和老化问题，以及未来的发展趋势。目前的研究现状表明，虽然基于计算机的局部放电测量的报道很多，但对基本老化特性的内在现象的研究却很少。这些数据对于扩展GIS绝缘的新概念是必不可少的。例如，指出固体材料的电应力增强研究是重要的，特别是与寿命估计和寿命控制技术以及制作更紧凑的地理信息系统有关。为此，需要从GIS的开发/设计阶段到测试/操作阶段引入一致的概念。这个概念将包括传感器集成的GIS、故障预测技术和应力控制寿命估计系统。本文从制造商的角度对这些建议进行了描述。
