A Type of Selection and Optimization Method of Medium and Low Voltage Fuse

中低压熔断器承担着保护电气设备和电网安全运行的重要任务,可以防止事故的扩大化,确保用户供电安全。但在实际使用中,人们较少考虑不同熔断器的适用性差异,以致选型不匹配导致的中低压熔断器事故频发。为解决这一行业痛点,本文提出一种基于逼近理想解法的熔断器性能评价方法,针对不同熔断器的运行特性提取特征参数,形成中低压熔断器性能评价指标体系,采用层次分析法确定各指标权重,列出评价的具体流程和步骤,并列举了中低压熔断器的选型优化实例,可为中低压熔断器在实际工程中的科学使用提供参考。

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 power supply forusers.However,in actual application,the applicability differences of different fuses is seldom considered,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.
