《输变电设备状态检修试验规程》新版技术解析
摘要：为适应电网发展的最新要求，对《输变电设备状态检修试验规程》进行了修订，强化了新技术的应用，重新构建了更加完备的状态分析方法。文中对新引入的智能巡检、带电检测、停电试验及状态分析方法进行了解析，对各项新技术的原理、适用场景和应用条件进行了详细说明，包括分析油纸绝缘受潮程度的频域介电谱、评估变压器绕组变形程度的扫频短路阻抗、检测断路器触头烧损情况的动态回路电阻、检测GIS及线路金具内部机械性缺陷的现场X射线检测等。此外，还对状态分析方法做了深入解析，包括单参量分析及多参量综合分析，阐释了各状态分析方法的理论基础，详解了关联状态量的概念并给出了应用案例。
Abstract:To meet the latest requirements of power grid development, the "Code of condition-based maintenance & test for electric equipment" published in 2010 has been substantially revised. In this revised edition the application of new technology was strengthened, and a more complete condition analysis method was reconstructed. In this paper, the newly introduced intelligent inspection, live detection, outage tests and condition analysis methods were analyzed, and the principles, applicable scenarios and application conditions of the new technologies were described in detail. Such items as the frequency domain dielectric spectrum for analyzing the degree of moisture of oil paper insulation, the frequency sweep short-circuit impedance for evaluating the degree of transformer winding deformation, the dynamic circuit resistance for detecting contact burning of circuit breaker, on-site X-ray detection for detecting mechanical defects in GIS and line fittings and so on were emphatically introduced. In addition, the condition analysis methods, including analysis based on single parameter and comprehensive analysis based on multi-parameter, were deeply analyzed, the theoretical basis of each condition analysis method was expounded, and the concept of associated condition indicators was further explained in detail and some application cases were given.
