摘　　要：在CJ20-25型交流接触器的动态参数测量数据的基础上,采用区间型隶属函数和三角形隶属函数创建了五级隶属度矩阵,并分别用三种评价方法对交流接触器的动态响应性能进行评价.通过比较发现,采用区间型隶属函数时三种评价结论一致性优于三角形隶属函数.该结论同样适用于评价其他同类低压电器产品的性能.Based on the dynamic tested data of Ac contactor CJ20-25 type, this paper respectively uses the interval type membership function and the triangular membership functions to create a category five membership degree matrix, and uses three kinds of evaluation methods to evaluate the dynamic response performance of ac contactor. Through the comparison, we found that the consistency of three evaluation conclusion by using interval type membership function is better than the triangle membership function. This conclusion is also applied into evaluate the performance of other similar low-voltage electrical products.
