Analysis of Factors Affecting the Working Performance of Brush slip ring system in Special Environment

Abstract In the marine environment, the wear of carbon brushes in the brush slip ring system of doubly-fed generators is accelerated and the replacement frequency is relatively high. In this paper, an experimental platform is built to simulate the working environment of the carbon brush slip ring system in the marine environment, and the factors causing the accelerated wear of carbon brushes are explored, so as to make suggestions on operation and maintenance of the brush slip ring system. The composition of the oxidation film on the contact surface of the brush slip ring has been quantitatively analyzed to provide a basis for determining the content of the oxidation film.
