Abstract

This paper presents a model to simulate electrical trees in dielectric materials. The model accounts for the characteristic tree patterns and the partial discharges associated with the propagation of trees. This simulation model is used as basis to develop a diagnostic tool to determine the remaining life of insulation materials by relating the fractal dimension of the tree to the supply voltage and material properties. Simulation results are presented to show the performance of the prognosis method.

用电介质击穿机理建模确定舰船电力系统中旋转机械的剩余寿命
本文提出了一种模拟介电材料中的电树的模型。该模型考虑了树木的特征模式和与树木繁殖有关的部分排放。以此仿真模型为基础,开发了一种诊断工具,通过将树的分形维数与电源电压和材料性能联系起来,确定绝缘材料的剩余寿命。仿真结果验证了该预测方法的有效性。
