Abstract

The contactor failure of important systems and key loops will lead to the speed reduction or even shutdown of the rail transit, affecting the operation. It is necessary to study on the deoxidation technology of contactor in rail transit, while most of the failures are found because of the increases of the resistance of contact in contactor due to the oxidation. The study shows good results that electric-deoxidation by making the contact pass through a larger current by load resistive and inductive reduces the failure of the contactor in rail transit applications.
