摘要 具有非线性电学参数的材料,其电导率或介电常数能够随着空间电场做出自适应的改变,从而达到智能改善绝缘介质空间电场分布均匀性的效果,可用于缓解高压设备局部集中的高电场。目前,国内外已经能够制备出具有高稳定水平的非线性电导特性的材料,如以氧化锌压敏微球为填料,以绝缘材料为基体的复合物。该文详细综述了国际上对于非线性电导材料均压的设计理论,介绍了如何根据实际改善电场分布的需求选择非线性均压材料的参数。在此基础上,总结国际上学者对于在材料制备过程中调控材料非线性参数以满足均压设计需求的研究工作。本文也对非线性均压材料在应用于实际高压设备方面的进展做了简单介绍。

Abstract:Materials with nonlinear electrical parameters possess field dependent conductivity or permittivity which can vary adaptively with the space electric field distribution. Thus, they can automatically enhance the uniformity of field distribution in insulation dielectrics and can be used to limit local overstress in high voltage apparatus due to concentrated electric field. Recently, domestic and international researchers have manufactured the materials with stable and nice nonlinear characteristics on conductivity, such as composite materials consisting of ZnO microvaristor fillers and insulation matrix. This paper elaborated the theory on design of materials with nonlinear conductivity for resistive field grading in high voltage apparatus. The theory mainly deals with how to determine the parameters of the nonlinear materials according to specific field grading requirements. The development of international researches on the parameter regulation of nonlinear materials during manufacturing process to meet those specific requirements is summarized. Finally, the progress of the nonlinear materials in practical high voltage apparatus is briefly introduced.
