一种电力绝缘材料的局部放电检测方法
摘要：
一种电力绝缘材料的局部放电检测方法，主要解决现有的电力绝缘材料局部放电检测方法造价高、精度低的缺陷等问题，本发明提供一种电力绝缘材料的局部放电检测方法，该方法首先在不带电情况下取出盆式绝缘子，再在盆式绝缘子上设置绝缘划痕缺陷；再对上述设置的绝缘划痕缺陷采用电子显微镜进行测量，利用便携超声波仪监测，同时利用高频X射线机对准GIS试验段盆式绝缘子划痕缺陷的位置进行连续照射，局部放电检测停止后，再次对绝缘划痕缺陷进行测量，比较后根据比较的结果判断电力设备固体绝缘材料缺陷的变化。本发明有效地提高了GIS缺陷检测效率和检测准确度,对于确保电力系统经济、可靠的运行具有重要意义。
摘要（英）：

The invention discloses a partial discharge detection method of an electric power insulation material, and is mainly used to solve problems of conventional electric power insulation material partial discharge detection methods such as high production costs and low precision. The partial discharge detection method of the electric power insulation material comprises steps that a basin-type insulator is taken out under an electrically neutral condition, and an insulation scratch defect is arranged on the basin-type insulator; the insulation scratch defect is measured by adopting an electron microscope, and a portable ultrasonoscope is used for monitoring, and at the same time, a high frequency X ray machine is used for continuous irradiation on the position of the scratch defect of the GIS test section basin-type insulator in an aimed manner, and after the partial discharge detection is stopped, the insulation scratch defect is measured again; after comparison, changes of a solid insulation material defect of an electric power device are determined according to a determining result. GIS defect detection efficiency and detection accuracy are effectively improved, and great meaning is provided for economic and reliable operation of an electric power system.
