Abstract

We propose the problem of diagnosing insulation defects of high-voltage electrical equipment based on monitoring of partial discharges, which are the main diagnostic sign of the defects. However, partial discharges cannot be measured directly. The issues of constructing a diagnostic model of an insulation defect as a source of partial discharge series and the problem of differential diagnostics of individual defects based on the interpretation of the integral pattern of partial discharges as a set of single partial discharge times available for measurement are considered. Diagnostics is based on the idea of a mathematical problem of covering a set. An example is given.

多种高压设备绝缘缺陷的离散诊断模型

摘要

我们提出了基于局部放电监测的高压电气设备绝缘缺陷诊断问题，这是缺陷的主要诊断标志。但是，不能直接测量局部放电。构建绝缘缺陷诊断模型作为局部放电序列源的问题和基于将局部放电的积分模式解释为一组可用于测量的单个局部放电时间的个别缺陷的差分诊断问题是考虑。诊断基于覆盖集合的数学问题的思想。给出了一个例子。
