To improve the quality and efficiency of inspection task of distribution equipment

this paper proposes a novel inspection strategy for period and path comprehensive optimization. Considering the importance and status of distribution equipment

the different inspection levels of distribution equipment are determined. And the differential inspection strategy of distribution equipment is formed based on the benchmark inspection period. A heuristic function containing traffic information is designed based on the principle of heuristic search algorithm

and A* algorithm is used to implement path search

ensuring that the search path is optimal. The specific inspection strategy is presented for a certain distribution equipment inspection task

and the inspection workload and time consumption under different strategies are analyzed

which verifies the correctness and effectiveness of the distribution equipment optimal inspection strategy. The results show that the importance of distribution equipment and real-time state evaluation method proposed in this paper can provide a reasonable basis for the establishment of inspection plan

so as to effectively reduce the inspection workload by about 40%. At the same time

the routing optimization algorithm designed by A* algorithm is used to realize the shortest routing optimization and the least time-consuming routing optimization.
