GIS is widely used in the fields of high voltage, ultra-high voltage and ultra-high voltage. The structure of GIS is compact, the floor area is small, the configuration is flexible and the reliability is high. Moreover, it has strong security and strong environmental adaptability. However, the electric field strength in GIS is very strong, once there are some defects in the equipment, partial discharge will occur, resulting in insulation deterioration of GIS equipment. In this paper, positioning detection technology is used, A fast live detection method of power equipment in complex area based on lilac is proposed. The position of the discharge source is roughly located, and then the linear electron accelerator is used to accurately locate the partial discharge source, which improves the efficiency of defect location. Based on the linear electron accelerator, GIS signal detection device is studied. In the detection, it is necessary to obtain the data generated by partial discharge signal, high-frequency current data and data for comparative analysis, so as to effectively eliminate the interference signal in GIS field, and improve the accuracy and defect type identification.

GIS广泛用于高压，超高压和超高压领域。GIS结构紧凑，占地面积小，配置灵活，可靠性高。而且，它具有很强的安全性和很强的环境适应性。但是，GIS中的电场强度很强，一旦设备中出现一些缺陷，就会发生局部放电，从而导致GIS设备的绝缘性能下降。本文采用定位检测技术，提出了一种基于丁香花的复杂区域电力设备快速实时检测方法。大致确定放电源的位置，然后使用线性电子加速器精确定位局部放电源，从而提高了缺陷定位的效率。基于线性电子加速器，研究了GIS信号检测装置。在检测中，有必要获取局部放电信号产生的数据，高频电流数据和进行比较分析的数据，以有效消除GIS领域的干扰信号，提高准确性和缺陷类型识别。
