摘要
采用二级模糊综合评判技术确定交流接触器的最佳合闸相角.首先利用正交试验建立了CJ20-25型交流接触器21个动态特征参数的原始数据库,然后按照二级模糊综合评判方法计算得到唯一评判指标.考虑到产品性能的差异,利用每台样品的评判值拟合曲线求解均值f准和方差S准,再进行一级模糊综合评价,综合考虑确定了最佳合闸相角的范围,且实验结果和仿真结果基本一致.实验结论可为同类电器产品性能的评判提供较为精确的试验条件.
The best closing phase angle of AC contactor is ascertained based on muhi-level fuzzy comprehensive theory. A database containing 21 dynamic parameters for CJ20-25 AC contactor is established by means of orthogonal experiment, and then the only evaluation index is determined by two-stage fuzzy comprehensive evaluation. Considering the differences between samples＇ performance, the average value f, and mean square error S, in the fitting curve of each product＇s evaluation value are solved, and then the best angle is determined by using the one-level comprehensive evaluation. The relsult of experiment is consistent with simulation, so it will provide more accurate equipment condition to evaluate the similar devices＇ performance.
