| Abstract(in English) | Our study aims to investigate the degradations of the contact material under arcing, in automotive power relays and switches. In this article we will present our results on the problem of the increase of the contact resistance after arcing, at 14VDC and 30-40A. We have seen that the contact resistance is much larger in an inductive circuit(up to 6 mΩ)than for a resistive circuit(below 1mΩ)with differences between the materials. This increase in the resistance in an inductive circuit is attributed to the deposit of pollution based on silver oxed and carbon based elements on the surface of the contacts(black powder)when the arc exceeds 200 μm or 2 ms and enters the gas phase. |
