X射线成像技术在组合电器中的应用研究

Application of X-Ray Imaging Technology in GIS Combined Electrical Apparatus

常规手段对组合电器内部结构进行开盖检查需要停电进行且需投入大量的人力物力,因此,做好对组合电器的状态监测、结构检测及事故预防非常重要。将X射线成像技术成功应用于电力设备,弥补了停电检测的缺点,节约了大量的成本。笔者研究X射线探伤原理、X射线检测仪器构成及操作,提出X射线检测的安全性措施,完成了组合电器隔离开关和断路器断口检测,通过试验进一步验证了X射线成像对SF6气体成分(即分解物)没有任何影响。X射线成像技术不仅适用于组合电器设备,也可应用于敞开式电气设备、绝缘子和金具探伤、电缆接头检测等。X射线成像技术实现了设备隐蔽缺陷的“可视化”,切实解决了传统工作中的一些难题,具有很高的推广应用价值。

It is necessary to cut off the power and invest a lot of manpower and material resources to open the cover of the internal structure of the GIS combined electrical apparatus for inspection by conventional means.Therefore,it is particularly important to do a good job in condition monitoring,structure detection and accident prevention of the combined electrical apparatus.X-ray imaging technology is successfully applied to power equipment,which cover the shortages of power failure detection and saves a lot of cost.The author studies the principle of X-ray flaw detection,the composition and operation of X-ray detection instrument,puts forward the safety measures for X-ray detection,completes the fracture detection of disconnector and circuit interrupter of combined electrical apparatus,and further verifies that X-ray imaging has no influence on the gas composition of SF6(i.e.decomposition products).X-ray imaging technology is not only suitable for combined electrical apparatus,but also can be used for open electrical equipment,insulator and fittings detection,cable joint detection and so on.X-ray imaging technology realizes the"visualization"of hidden defects of equipment,solves some problems in traditional work,and has a very high value of popularization and application.
