This paper analyzes the composition

working principle and main problems of the existing building electrical disaster prevention system

and proposes a set of optimization strategies based on performance evaluation combined with relevant standards and technical specifications. It has established an effectiveness evaluation index system for the electrical disaster prevention system

and conducted a detailed analysis using appropriate evaluation models and methods. The case study shows that the evaluation method can effectively identify the weak links in the system

which provides a theoretical basis and technical support for the performance improvement and fault prevention of the building electrical disaster prevention system.
