摘　　要：针对输变电设备的维修管理,提出基于风险评估的维修技术。通过构建完整的输变电设备风险评估体系与基于风险的维修决策方法,建立了将基于风险的维修(RBM)方法应用于输变电设备维修的基本技术框架。与已有维修技术相比,文中通过引入风险评估理论与区间分析思想,不仅使维修决策更为经济和科学,而且将技术的可操作性大大增强。在某地区电网的应用结果表明:该方法全面评估了设备风险,能够快速、有效地进行维修决策,具有很好的应用前景。In view of the maintenance management of electric transmission equipment,a new maintenance technology based on risk assessment is proposed.Through the procedure of risk assessment and the method of decision-making,the basic technical framework that applies risk-based maintenance（RBM） to the maintenance of electric transmission equipment is developed.By employing the risk assessment theory and interval analysis,the technology has not only made maintenance decision-making much more economical but also greatly enhanced technology operability. Application of the technology in an actual regional power grid shows that it can comprehensively evaluate the risk to equipment and make expeditious decision-making, signaling good application prospects for the technology proposed.
