摘要
X射线数字成像DR技术由云南电力研究院率先引入到电网运行设备的无损检测当中。某些电力设备以油或SF6气体作为绝缘介质以起到灭弧、散热、绝缘等作用,变压器、电容器、充油电缆等设备中的油如果劣化将导致油绝缘性能变坏,击穿电场强度降低,介质损失角增大,进而会导致设备性能下降甚至导致设备烧毁事故,论文是对变压器油在X射线长时间照射条件下油质变化情况的研究。
X- ray digital imaging DR technology is first introduced intO the to the run non -destructive testing equipment in grid by the Yunnan Electric Power Research Institute, but some electrical equipment, use oil or SF6 gas as insulating media in order to play the role of interrupter, cooling, insulation, etc. If the oil of the transformers, capacitors, oil -filled cables and other equipment deteriorate, it will result in oil insulation per- formance deteriorated, breakdown electric field strength decreases, the dielectric loss angle increases, and then will cause device performance degradation or even cause the device to burst. The article is a study about the oil quality changes of transformer oil under conditions of prolonged exposure to X - ray.
