Development of the automatic control system of the blower motors of the diesel electric locomotive

Abstract

The main tasks of the railway industry are focused on reducing the costs associated with the operation and repair of technological equipment. It is possible to solve them by the development of technical means that optimally take into account the natural and climatic, geographical and technical operating conditions. In these operating conditions, the development of locomotive traction involves the modernization of the existing fleet of traction rolling stock, improvement of the locomotives produced, the development of a paradigm-shifting platform of lines of innovative locomotives, the replacement of equipment by more reliable and modern one, and the automation of processes. Automation makes it easier to control the locomotive, reduce the risk of errors and ensure the most rational equipment operation modes. It was found that the damage to the electric parts of the electric motors accounted for more than 70 percent of the total number of faults. The purpose of this article is to develop a technical solution, the use of which will minimize the number of failures of auxiliary machines and locomotive equipment of this series. To implement this, it considers the main design features of electric motors, their connection diagram and the presence of protection elements to determine the trouble spots and justify the proposed technical solution.
