Increasing the Reliability of the Oil Pump of the Traction Transformer of an Electric Locomotive

https://doi.org/10.46973/1818-5509_2024_3_61

Abstract

A large number of failures of traction transformer oil pumps are due to the auxiliary electric drive. The paper examines the factors and operating conditions of the auxiliary electric drive that affect its accelerated aging and failure of oil pumps. In order to identify the causes of failures, an analysis of the Ishikawa diagram was conducted. The analysis revealed that most failures are due to the asynchronous electric motor, due to its operation in difficult conditions. To increase the service life of the oil pump, it is proposed to replace the asynchronous motor with a valveinduction machine.
