Studty of the Arc Erosion in Electromobile Contactor Electrode Consisting of Ag and C Composites

The contactor system plays a pivotal role when it charges and drives in the aspect of security and stabilization in new energy vehicles. The erosion of the electrodes in contact system is one of the most noticeable issue to be solved to prolong the electrical endurance and reduce the accident. For a better understanding of the erosion mechanism and the distinction of different compound silver material, in this work a high-speed imaging technique combined with a near-infrared laser illumination and a digital image process is proposed to allow the visualization of electrode surface morphology and measurements of the time-resolved splashing erosion rate to be achieved.
