摘要

中压真空断路器在线状态评估是实施状态维修的基础。笔者提出一种中压真空断路器的模糊-DS证据理论在线状态评估模型

在分析真空断路器构造和常见故障基础上建立评估指标体系;依据模糊隶属度函数原理确定断路器各指标证据的基本信任分配;运用DS证据理论中的规则合成原理融合各指标证据

采用改进的Levre合成规则弥补DS规则合成存在的缺陷;然后基于置信度准则决策规则给出断路器的状态评估结论。实例证明该模型是正确和有效的。

Abstract

Online condition-based assessment of medium-voltage vacuum circuit breakers（VCB） is the basis for its maintenance.A fuzzy-DS evidence theory assessment model of VCB is presented.The index system of VCB is set based on the analysis of VCB’s structure and fault characteristics.Basic belief assignment function of each index is determined according to fuzzy membership functions.Different indices are combined by DS combination rule

and the improved Levre combination rule is used to solve the evidence conflict.The condition of VCB can be gained by the decision-making method based on the reliability code.The test results show the model is correct and effective.
