| 摘 要： | 动态电感和合闸位移是衡量智能交流接触器动态特性的两项重要参数,为对动态电感和位移进行预测,引入空气间隙与等效磁阻之间的数学关系,建立了一种智能交流接触器等效磁路模型。通过在线检测线圈输入电压和电流,实现对动态电感和合闸位移在线实时监测的目的,可有效掌握和评估智能交流接触器的实时动态特性。采用激光位移传感器对接触器动态特性进行同步对比实验,实验结果显示预测位移与位移传感器实际测量位移较为吻合,表明在无需位移传感器的条件下,可有效预测接触器的动态特性。

| Abstract: | Dynamic inductance and closing displacement are two important parameters to measure the dynamic characteristics of intelligent AC contactor. In order to predict the dynamic inductance and displacement, the equivalent magnetic circuit model is developed by employing the mathematical relationship between the air gap and the equivalent reluctance. Aiming at monitoring the dynamic inductance and closing displacement online, the real time input voltage and current are detected and the dynamic characteristics of the contactor can be effectively evaluated. The comparison experiments are carried out by using laser displacement sensor. The simulation results show that the real displacement can be effectively predicted by the proposed model, which means that the dynamic characteristics can be evaluated without using the displacement sensor. |
