摘　　要：随着电气工程和柔性输配电的快速发展,高介电常数和高电导率的多功能聚合物基复合材料受到越来越广泛的关注。广泛应用于高压输配电领域的聚乙烯(PE)绝缘材料介电性能优良,但空间电荷和水树枝等对其电气性能影响很大。介绍了目前聚乙烯空间电荷的抑制及测量方法的研究现状,展望了空间电荷分布改善及测量方法改善的研究方向。With the rapid development of electrical engineering and flexible power transmission and distribution, the multi-functional polymer based composites with high dielectric constant and high electric conductivity have got more and more attention. Polyethylene（PE）, which applied in high-voltage direct current transmission and distribution field, has good dielectric property, but the space charge and water tree branches in PE have big influence on its dielectric property. The situation of space charge suppression and measurement methods of PE at present were reviewed, and the research directions of the space charge and measurement methods were proposed.
