Abstract

Today it seems to be beneficial to investigate how nanoparticles can serve to improve the electrical properties of insulation materials and how this affects their behavior during processing and other physical or chemical characteristics. However; a crucial factor is the choice of the filling material in combination with the carrying matrix as well as the filling technology. Hence it is useful to develop a testing arrangement that allows one to perform a significant number of tests on different materials and enables a high voltage laboratory to investigate the strength under electrical stress levels that generate partial discharges. Therefore; a testing device in accordance to IEC 60343 has been modified to use a very common and easy-to-produce plate shape for specimens and to increase throughput. Also this device allows to detect gases or to change the electrical field geometry. This paper reports on experiences with different contents of nano sized silica particles in epoxy resin matrices. This is the basis for the development of new insulation systems to be used for a more effective design of high voltage devices like rotating machines.

纳米绝缘材料的测试:一些想法，一些经验

今天，研究纳米粒子如何改善绝缘材料的电学性能，以及这如何影响绝缘材料在加工过程中的行为和其他物理或化学特性似乎是有益的。然而;充填材料的选择和载体基质的选择以及充填工艺的选择是影响充填效果的关键因素。因此，开发一种测试安排是有用的，这种安排允许人们对不同的材料进行大量的测试，并使高压实验室能够研究在产生局部放电的电应力水平下的强度。因此;符合IEC 60343的测试设备已被修改为使用非常常见且易于生产的样品板形状并增加吞吐量。此外，该装置允许检测气体或改变电场几何形状。本文报道了不同含量的纳米二氧化硅在环氧树脂基体中的应用经验。这是开发新的绝缘系统的基础，用于更有效地设计高压设备，如旋转机器。
