Experiments were carried out at several voltages to clarify the influence of the voltage on various characteristics, i.e. arc duration, contact resistance, arc energy, and the change in electrode mass. The voltage was varied from DC100V to 160V, the load current was fixed at 5A constant, and the electromagnetic contactor was operated continuously up to 100,000 times. The experiments were carried out under the three arcing operations which were classified by the arc discharge. As a result, the relation between the arcing operation and arc duration time, contact resistance, and electrode mass change is clarified. When only a make arc is generated, the contact resistance was smallest. In addition, the contact resistance is not affected by the source voltage. Furthermore, it has been found that the anode loss per unit arc energy is large. |
