Abstract

Experiments are carried out to clarify the influence on the current and voltage for various characteristics. A small electromagnetic contactor that has two contacts is used. The arc discharge with only a make arc is generated and various characteristics are measured. Source voltage is set to 100V or 3V DC, closed contacts currents are changed from 10A 20A and 30A. From the waveforms, the arc duration time and the bounce time are read out. Arc energy is calculated from the arc voltage and arc current. The contact resistance is calculated from the voltage drops. In DC100V, the arc duration time and the bounce time were not influenced by a closed contact current. The arc energy was increased by a closed contact current. The contact resistance was slightly decreased with current increases. The mass change of electrodes, the anode was decreased and the cathode was increased. Further the electrode mass change per unit arc energy vs. closed current was relatively constant. But, in DC3V make arc duration is very short and electrode mass change is very small.

电磁接触器在产生电弧放电时的各种特性只产生电弧

通过实验阐明了各种特性对电流和电压的影响。使用两个触点的小型电磁接触器。仅产生一个电弧的电弧放电，并测量了各种特性。源电压设置为100V或3V DC，闭合触点电流从10A、20A和30A变化。从波形中读出电弧持续时间和弹跳时间。电弧能量由电弧电压和电弧电流计算得到。接触电阻由电压降计算。在DC100V环境下，触点闭合电流不影响电弧持续时间和弹跳时间。闭合触点电流增加了电弧能量。随着电流的增大，接触电阻略有减小。电极质量变化，阳极质量减小，阴极质量增大。此外，每单位电弧能量与闭合电流的电极质量变化相对恒定。但是，在DC3V中，电弧持续时间很短，电极质量变化很小。
