The invention relates to the field of optimization methods, and in particular to a high-voltage cable inspection period optimization method based on risk assessment, which comprises the following steps: establishing a risk assessment model of a cable system, calculating a function relationship between the risk of a wire system and an inspection period in the model, obtaining required numerical values and constraint conditions from an existing inspection period, and calculating an optimal inspection period. In the cable system risk assessment model, the cable fault probability reflects the fault condition of the cable system in real time, and the risk value of each part of the cable dynamically changes accordingly. By adopting the scheme of the invention, the corresponding optimal inspection period can be calculated in real time according to the dynamic risk value of each component, operation and maintenance management resources are reasonably allocated, differentiated inspection is carried out on each compone
