摘要

大型电力变压器内部的局部放电信号经绕组向两端传播至监测装置

从而导致作为故障诊断基础信息的放电脉冲信号发生一定程度的衰减、振荡及时延。运用Saber仿真软件

利用典型的局部放电的波形

考虑电力变压器外联网络复杂程度以及变电站另一个变压器对其的影响

研究了局部放电信号在大型电力变压器在线监测系统中的传播特性。

Abstract

The internal partial discharge （PD） signal of large power transformer may propagate to the monitoring device through transformer winding. As a basic information for fault diagnostic

discharge pulse signal can be distorted with some attenuation

oscillation and time delay. Utilizing the simulation software Saber and the PD waves

considering the complex of external network of power transformer and the influence from another power transformer in substation

the propagation characteristic of PD signal is studied in a on-line monitoring system of large power transformer.
