| 摘 要： | 针对设备故障发生概率的不确切因素,运用模糊故障树理论对低压开关设备进行可靠性分析。通过梯形模糊数,对低压开关设备MCC的送水泵电路进行分析,得出电路发生故障的模糊概率及底事件的模糊重要度。研究结合了概率本身的模糊性和工程上的误差,在可靠性工程上具有广泛的应用前景。

| Abstract: | In view of the inaccurate factors for the probability of equipment failure,the reliability analysis of low voltage switchgear system was analyzed by fuzzy fault tree theory.According to the analysis of water pump circuit system of low voltage switchgear using trapezoidal fuzzy number,the fuzzy probability of return route failure and the fuzzy importance degree of bottom event were obtained.Combing with the fuzziness of probability and the project error,it has wide spread application prospect in the reliabil... |
