交流励磁接触器吸合动态过程的仿真研究

Study on dynamic closing course simulation and experiment for AC contactor

在交流接触器的设计与操作中,研究其动态过程对于优化设计操作电磁铁和提高其整体性能具有非常重要的意义。利用LabVIEW软件编程建立了接触器闭合过程的动态数学模型,模型实现了对接触器动态过程的仿真分析。在此基础上仿真研究了不同合闸相角、线圈电压对接触器闭合过程及其对触头弹跳的影响,为研究接触器的动态特性提供了途径。

In the optimum design of AC contaclors, it is necessary to analyze its dynamic behavior in the circuit, especially for improving the capability of contactor and designing the electromagnet. A dynamic mathematic model of AC contactor is proposed by labview and also simulated the dynamic behavior of contactor. The influences of the different electrical circuit parameters and contact spring parameters on the contact bounce are investigated. The proposed method is useful in the dynamic behavior.
