摘　　要：直升机巡检作为输电线路的新型运维方式,具有效率高、效果好等优点,但其规模化推广应用要以安全作业为前提。本文利用风险矩阵法建立了直升机巡检作业安全风险评估模型,从人员、设备、环境三方面分析了作业全过程的安全风险因素,根据风险可能性和后果严重程度两个维度确定风险值,进而根据风险值在风险矩阵中的位置评价各风险因素的风险等级,有针对性地提出了差异化的风险控制措施,为避免高风险作业,保证电网、作业人员、设备安全提供了有利支持。As a new type of operation and maintenance mode for transmission lines, helicopter patrol inspection has the advantages of high efficiency, good effect, etc. However, its large-scale application should be based on the premise of safety operation. In this pa- per, a safety risk assessment model of helicopter inspection is established by using risk matrix, in which the safety risk factors of the whole operation process are analyzed from the aspects of personnel, equipment and environment. The risk value is determined by the risk probability and the consequence severity, and then the risk level of each risk factor can be assessed according to the position of the risk value in the risk matrix. Differentiated risk control measures are proposed to avoid high-risk operations and provide a favorable support to ensure the safety of power grid, operating personnels and equipment.
