Dielectric gradient components have advantages in electric field mitigation and insulation improvement. In this paper, we propose a fabrication method for adaptive dielectric gradient components using in situ AC electric field, including the mechanism and the corresponding operational procedures for industrial applications. Based on the electric polarisation and self-assembly effect of the filler particles in the liquid matrix, the chain-like structure in the high field strength region is constructed to enhance the local permittivity and mitigate the maximum of the spatial electric field. The dielectric gradient basin insulator is prepared by this method, and its flashover voltage is increased by 12.8% compared with that of a homogeneous dielectric basin insulator, and the improvement is 20.8% when metal particles are present on the surface. The more non-uniform the initial electric field is, the greater the improvement in flashover voltage. This method is expected to promote the industrial application of dielectric gradient insulating components.

一种自适应介电梯度绝缘元件的制作方法

介电梯度元件在减轻电场和提高绝缘性方面具有优势。在本文中，我们提出了一种使用原位交流电场的自适应介电梯度组件的制造方法，包括工业应用的机制和相应的操作程序。基于液体基质中填料颗粒的电极化和自组装效应，在高场强区域构建链状结构，以增强局部介电常数并减轻空间电场的最大值。采用该方法制备的介质梯度盆式绝缘子，其闪络电压较均质介质盆式绝缘子提高了12.8%，当表面存在金属颗粒时提高了20.8%。初始电场越不均匀，闪络电压的改善越大。该方法有望推动介电梯度绝缘元件的工业化应用。
