The medium and low voltage fuses undertake the important task of protecting safe operation of electrical equipment and power grids

which can prevent the expansion of accidents and ensure safety of powersupplyforusers.However

causing frequency accident of medium and low voltage fuses due to selection mismatch. In order to solve the pain point of this industry

a kind of fuse performance evaluation method based on approximate ideal solution is proposed in this paper. The characteristic parameters for the operating characteristics of different fuses are extracted and the fuse performance evaluation index system of the medium and low voltage fuse is formed. Moreover

the analytic hierarchy process is adopted to determine each index weights. The specific process and steps of the evaluation are listed and the type selection and optimization examples of medium and low voltage fuses are given

which can provide references for the scientific use of medium and low voltage fuses in actual projects.
