Estimation of wear of contact brazing from composition materials of contactors of alternating current electric locomotives

Abstract

The results of experimental researches of technological and operating wear of contact brazing are resulted in work. It is indicated on the negative sides of repair treatment of contact brazing, but also its necessity is argued. The features of wear of contact brazing from different materials are considered. Probability of faultless work after the criterion of thickness of brazing at the different runs of electric locomotives for different materials of contact brazing, and also Ƴ-percent resource of contacts is got. Histograms and theoretical laws of distributing of runs l of electric locomotives are resulted to the refuse of contacts from the probed materials. A conclusion is given in relation to the most reliable and lasting material for brazing on the contacts of contactors EKG-8 and PC-96-101.
