Experiments were carried out in AgNi contacts to clarify the various characteristics, arc duration, contact resistance, arc energy, and electrode mass change. In previous experiments, the arc were generated in three conditions, both of make and break arc, only a break arc, and only a make arc. The source voltages and load current were set to DC100V, 5A and an electromagnetic contactor is operated continuously up to 100,000 or 10,000 times. The Cu and CuCr contacts were used. When only a make arc was generated, the contact resistance was small. However, when both of make and break arc were generated, the contact resistance has increased rapidly, and the contact failure was caused.. |
