数字技术用于电力变压器局部放电定位

Digital Technology for Partial Discharge Location of Power Transformer

文中作者介绍了一种电力变压器局部放电的电气定位技术。它利用在特定的频率段变压器内的放电脉冲线性传播的特点,确定局部放电位置。所创立的技术及相应的设备已在变压器出厂试验及变电站运行变压器在线监测中证明该项技术可以准确检测出故障变压器的放电位置。

In this paper, the author introduces an electrical positioning technique for partial discharge of power transformer. It uses the characteristic of linear transmission of discharge pulse in transformer in specific frequency range to determine the location of partial discharge. The technology and the corresponding equipment have been proved that the technology can accurately detect the discharge position of the faulty transformer in the transformer factory test and the transformer online monitoring in substation operation.
