5. 接触器动态性能检测技术与综合评判方法
对电器技术性能的考核主要还是采用型式试验，该方法侧重于考察电器的机械与电气寿命，并不能对电器的动态特性及其机械电气寿命的影响进行综合评估。因此研究基于动态特性检测的电器性能综合评估对于电器产品的研制与出厂检测具有实际意义。文献通过对交流接触器动态过程进行测试，从触头测试波形中提取能够表征接触器机械及电气特性的参数，通过建立接触器性能综合评判模型，从而形成接触器动态性能综合评判系统。交流接触器动态测试装置以DSP为核心，搭建各种信号传感器，通过RS232 与上位机进行数据通信。该测试装置可以完成对接触器励磁电流、电压，吸合过程线圈功耗的电气参数的测量。对本课题试验装置的搭建具有实际的作用，同时其提出的接触器性能评判系统对本课题将要研究的接触器性能退化及可靠性估计具有重要的参考价值。
