变压器超高频检测信号处理单元的设计

The Design of Signal Disposal Cell with UHF Signal Detection for Transformer

在分析了电力变压器局部放电的超高频特性的基础上,利用混频技术,设计了局部放电超高频信号的信号调理单元,方便普通数字采集卡采集。

Based on an analysis of UHF（ultra-high-frequency）characteristic of PD（partial discharge） in power transformer, using mixing technique, a signal disposal cell has been devised for the sake of facilitating common data sampling card.
