本文主要介绍了X射线检测技术在GIS设备缺陷诊断的应用研究，详细的介绍了X射线检测技术在GIS故障诊断中应用的三个案例。主要介绍了应用X射线检测GIS内部结构装配、有无部件松动、损坏的情况；以及介绍了X射线对PRDP图谱的影响，医学CT3D成像分析的应用。最后，从X射线检测技术的有效性、安全性、可行性三个方面进行了总结，对X射线检测技术在GIS设备缺陷诊断中应用的主要成效和推广建议进行了阐述。
本文对某风电场220kVGIS（金属封闭气体绝缘组合电气设备，Gas Insulated Switch-gear,GIS）A相引出线瓷套管和A相避雷器瓷套断裂倒塌的原因进行了分析。通过查阅制造厂出厂检验报告、工艺规程和作业指导书等资料，并进行现场查勘，找到了220kVGIS A相引出线瓷套管和A相避雷器瓷套断裂的原因。分析认为220kVGISA相出线套管和A相避雷器瓷套的断裂原因是这两个瓷套管均存...
基于GIS的漳河上游城市非点源污染负荷估算
非点源污染 次降雨径流污染物平均浓度 污染负荷 空间分析 漳河上游
2020/6/11
为了解漳河上游水污染成因，2017年对长治市城区典型功能区不同下垫面进行了11场降雨监测，分析了次降雨径流污染物平均浓度(EMC)，采用平均浓度模型法估算了2017年漳河上游各城市非点源污染年负荷，并结合ArcGIS技术分析了各市县污染程度。结果表明:2017年，长治市城区降雨径流非点源污染较为严重；各功能区路面径流污染物的EMC值大于屋面，主要污染源为SS、CODCr、TN和重金属Cd；商业区路...
