摘要(Abstract)：

GIS设备母线导体连接触头的间隙过大会引起故障发生,为检测间隙状态,使用数字化射线成像技术(DR)进行触头间隙的诊断,通过一系列试验,得出了DR技术检测的合适参数。实践证明,在合适的透照参数下进行拍摄,可清晰观测出GIS设备母线导体连接触头间隙情况。
The oversized busbar contract clearance of GIS may result in faults.For detection of the clearance status,the digital radiography(DR) technology is employed to diagnose the contract clearance.By a train of test,proper parameters for DR technology are concluded.It is proved by the practical application that the shoot under appropriate radiographic parameters can clearly reflect the clearance of busbar connection contact of GIS.
