【摘要】 对高压断路器运行状态的有效评估是开展状态维修的重要依据。针对目前几种评估方法的不足,应用基于物元理论的高压断路器状态评估方法,综合电气试验、机械试验、外观情况、工作环境及检修状况等因素,用关联度函数分析各指标对物元的归属程度,定性和定量地评估断路器的运行状态;同时,在用层次分析法确定指标权重的基础上,引入基于均衡函数的变权模式,综合考虑指标间的均衡性,对权重进行修正得到变权,从而提高评估的准确性。经实例分析证明了该方法的有效性。更多还原

【Abstract】 The effective assessment of circuit breaker status is crucially important for developing condition maintenance.Due to faults in the existing assessment method, we develop a method based on matter-element theory to assess the condition of high-voltage circuit breakers.A method based on electrical testing,mechanical properties,appearance,working environment and maintenance condition can analyze the ascription degree of each index with relevant functions and evaluate the circuit breaker status qualitatively and quantitatively.At the same time,using the analytic hierarchy process(AHP) method to determine the constant weight of every index,we introduce a variable weight model based on a balanced function.This model considers the proportionality synthetically among every index and derives variable weights by modifying the constant weights,thereby improving assessment accuracy.The condition assessment method for high-voltage circuit breakers based on matter-element theory is shown to be effective based on experimentation with an actual circuit breaker.更多还原
