摘要 交流接触器分断过程中的电弧侵蚀是造成其失效的主要原因,因此通过控制电弧对触头的侵蚀,可以提升交流接触器的使用寿命。该文分析了起弧相角对触头电弧侵蚀的影响,对随机起弧相角、固定起弧相角、三相均匀磨损三种控制方式下的交流接触器电寿命进行研究;分析由于交流接触器释放时间的不确定性引起的起弧相角的随机性,利用软件仿真分析起弧相角具有随机性情况下交流接触器电寿命的变化趋势和特征,提出以起弧相角标准差为参量的最佳释放时刻的控制方法,并提出根据实时服役参数进行交流接触器电寿命最大化控制;通过实验测试获得起弧相角的均值和标准差,并在固定相角控制、随机相角控制、电寿命最大化控制方式下进行对比实验,证明了在电寿命最大化控制方式下各相触头的电弧侵蚀量均匀且侵蚀率最小,可以显著提升交流接触器的电寿命。

Abstract:The failures of AC contactors are mainly caused by the arc erosions during breaking electrical circuits, and therefore, the electrical life of contactors can be increased by controlling the arc erosions properly. The effect of arc starting phase angle (ASPA) on the arc duration and hence the arc erosion was analyzed in this paper, and the differences of the electrical life under three control modes, including the random ASPA control, the fixed ASPA control and the three-phase uniform wear control, were also investigated in detail. The randomness of the ASPA caused by the inconstant release time of AC contactor was analyzed, and then the characteristic of contactor's electrical life under this randomness was analyzed through simulation. A maximum life control method based on the standard deviation of ASPA to control the optimal releasing moment of AC contactor, in terms of minimizing the arc erosion, was proposed in this paper. In application, the releasing moment of contactor can be adjusted properly and automatically according to the real-time operating parameters to maximize the electrical life of AC contactor. Experiments under the three control modes prove that the arc erosions of three contacts are almost the same and the erosion rate is the minimum under the maximum life control, and the electrical life of the AC contactor is significantly increased.
