| 摘 要： | 针对GIS设备缺乏有效检测手段且其在电网中的重要性,云南电网在全球率先将X射线数字成像DR检测技术应用到GIS设备的可视化无损检测中。目前,X射线数字成像DR检测技术在电力设备可视化检测中的应用才刚刚起步,还没有现场试验操作规程、X射线机参数选择标准、图像处理系统等理论支撑。然而,在X射线成像过程中,曝光量直接影响着X射线数字成像质量,由此基于大量的现场试验及计算,提出了曝光量在GIS设备X射线可视化图像的选择方法。 |
| 关 键 词： | GIS 曝光量 X射线 无损 |

| Abstract: | Considering the important position in the power grid of GIS equipment.Yunnan power Grid has taken the lead to put X-ray digital representation technological in the application of Visualization Nondestructive Testing.But now,the application of X-ray used in electrical equipment is still at the beginning,there is still no field investigation operation rules、standards for X-ray machines to chose、image processing system and other theory foundations.The article based on a goodly amount of field investigation and also a lot of calculations,and put forward a theory about the selection method of X-ray exposure parameter in the application of Visualization Nondestructive Testing. |
| Keywords: | GIS exposure X-ray Non-destructive |
