摘要
传统的局部放电检测方法,由于测量频带窄、抗干扰能力差、信息量少,已不能满足电力设备局部放电检测的需要。本文基于平行传输线原理设计制作了一种超宽频带传感器,其上限截止频率高达3GHz,并运用该传感器去研究局部放电信号,表明其具有良好的使用特性,为进一步在超宽频带范围内研究局部放电奠定了基础。
The traditional partial discharge detection methods could not meet the requirement of the partial discharge detection for power equipment, because of their narrow measuring-band, poor anti-interference performance and less information. On the base of the principle of parallel transmission line, authors designed and developed a kind of ultra-wideband sensor. The upper cutoff frequency of the sensor comes up to 3GHz. The sensor was applied to measure partial discharge signal, and it is found that the sensor has superior performance characteristic. It is very suitable for partial discharge investigation in ultra-wideband.
