Evaluation and Comparison of the Arc Erosion Characteristic of Ag/SnO

摘要

The arc erosion characteristic of contact materials is one of the key factors for the electric life of a relay. A new simulation testing device used for evaluating the arc erosion characteristic was built in order to meet the need of engineering application, and its action characteristic was almost the same as relays. The reliability and availability of the simulation testing device were confirmed by lots of designed parameter testing and analysis. The arc erosion characteristic of Ag/SnO
