摘要
本文提出了一种测量含偶极子的复合绝缘材料在各种温度下内部电场强度的新方法——分离-热刺激电流法。介绍了这种方法的设备、测量方法,分析了测量误差,给出了用这种方法测量EVA-PE(乙烯-乙酸乙烯酯共聚物与低密度聚乙烯)复合绝缘内部场强的结果及用此法判断复合绝缘内部空间电荷位置的方法。
This paper presents a 'Separation-thermally stimulated current method', which is a new method for measuring internal electrical field of composite insulation material containing dipote undeT different temperature.The system setup and measuring process of this method are explained. It discusses the accuracy of the method, and provides the experimental results on internal electric field of PE (polyethylene) and EVA (ethylene-vinyl acetate copolymer) composite material. The procedure for identifying the space charge location in the composite material are described and the obtained results are given.
