摘要

局部放电特高频检测是发现电力变压器早期缺陷的重要手段。现有内置式特高频传感器安装阻力大，外置传感器检测灵敏度低。为此，文中提出一种油箱接缝式特高频传感方法。通过仿真建模与实测分析研究了局部放电电磁波在油箱接缝内外的能量空间分布特征以及极化特性；而后进行了接缝式传感器的选型，研究了一种适于安装在缝隙中限位方钢断口处的锥形传感器，并对传感器的形状尺寸、馈电结构进行了优化设计；最后通过增设反射背腔进一步提高传感器的检测灵敏度。研究结果表明，当放电发生在油箱内部时，缝隙内部信号的电场强度平均为缝隙外部的3～5倍；设计的接缝式传感器的检测幅值可达到传统外置式领结天线的2～3倍。油箱接缝式特高频传感器便于现场安装应用，且具有较高的检测灵敏度，具有较高的推广应用价值。

Abstract

UHF (Ultra high frequency) on-line detection of partial discharge is an important means to find the early defects of power transformers. The existing UHF sensors and their installation methods have the problems of low safety

reliability and sensitivity. For this reason

this paper has proposed a seam UHF sensor method which application in the Transformer oil tank. The energy distribution characteristics and polarization characteristics of discharge electromagnetic signals inside and outside the seam were studied through simulation and experimental analysis. Secondly

the selection and design of seam sensors were carried out

and a conical sensor suitable for installation at the limiting square steel opening was developed. To improve the detection amplitude

the sensor's feeder shape

size and structure were optimized

and a reflective back cavity was also added. The research results indicate that when discharge occurs in-side the fuel tank

the signal electric field intensity inside the seam is on average 3-5 times that of the outside of the seam; The detection amplitude of the designed seam type sensor can reach 2-3 times that of traditional external tie antenna. The seam UHF sensor is convenient for installation and application

and can realize high sensitivity detection of partial discharge

this sensor is highly valuable for promotion and application.
