摘要
为了保证真空断路器的安全运行,必须对其运行状态进行客观合理的评估.采用基于云模型与物元理论来评估真空断路器运行状态.利用真空断路器的相关试验和实际运行参数建立了运行状态评价指标体系;基于云模型的双重不确定性和物元理论的可定性构建了一个云物元理论的评估模型.运用该模型对算例进行状态评估,验证了模型的可行性与可靠性,为真空断路器的安全运行提供了理论基础.
Abstract
The vacuum circuit breaker operation state must be evaluated objectively and reasonably in order to ensure the safet operation.This paper employs the cloud model and matter-element theory to evaluate the vacuum circuit breaker operation state.First of all,establish evaluation index system of running state based on the relevant test and actual operation parameters of vacuum circuit breaker; construct an assessment model of cloud matter-element theory based on the double uncertainty of cloud model and certainty of matter-element theory.Finally state evaluation was carried out by using the model,verifying the feasibility and reliability of the model,and providing the theoretical basis for the safe operation of the vacuum circuit breaker.
