Embodiment

[0137] In order to illustrate the feasibility of the improved AHP, residential users are selected for electrical equipment safety assessment. First, the hierarchical distribution of residential user electrical equipment safety assessment indicators is constructed, that is, the target layer is the residential user electrical equipment index M4, and the scheme layer is The service life of electrical equipment for residential users M41, the aging rate of electrical equipment for residential users M42, the number of annual failures of electrical equipment for residential users M43 and the protective grounding status of electrical equipment for residential users M44;

[0138] One expert is selected, and according to the interval proportional scale table (such as Table 2), the importance of the safety indicators of residential electrical equipment is compared and scored. The expert's scoring table is shown in Table 3:

Abstract

The invention provides a user electric equipment safety assessment method based on an improvement section analytic hierarchy process. The method comprises the following steps that a safety assessment index system of user electric equipment is established, and an expert grades a safety assessment index; the indeterminacy value of a judgment section is converted into a determinacy type value with the improvement section analytic hierarchy process; a section judgment matrix is constructed, and the maximum eigenvalue and eigenvector of the matrix are calculated; consistency of the section judgment matrix is tested, and weights of all safety assessment indexes are determined. According to the user electric equipment safety assessment method based on the improvement section analytic hierarchy process, the user power utilization safety can be effectively assessed through the assessment result, and a powerful basis is provided for preventing the human casualty accident of power utilization safety; compared with a common analytic hierarchy process calculation result, the feasibility of the method is shown, and a certain reference is provided for the user power equipment safety assessment.

Description

technical field [0001] The invention relates to an evaluation method, in particular to a user electrical equipment safety evaluation method based on an improved interval analytic hierarchy process. Background technique [0002] Electric shock, equipment misuse, long-term disrepair of equipment, violations of regulations and other reasons often cause user-side power consumption personal injuries and deaths. According to the statistics of the National Energy Administration, in 2013, the number of deaths in power production reached 57, and the death toll in power construction reached 10. 26 major incidents of electric power safety. The deep-seated reasons for electricity safety casualties, on the one hand, are due to the insufficient awareness of safety awareness of electricity safety inspection and management personnel, or insufficient grasp of electrical equipment and safety requirements and standards; Conduct reliable safety hazard judgments on electrical equipment.
