Modified ‘Yermak’ Locomotive is under Test Trials


Novocherkassk Electric Locomotive Building Plant (NEVZ, an entity of JSC Transmashholding) sent for type tests its modified 3ES5K ‘Yermak’ locomotive, according to Transmashholding department for external relations. 

An electric locomotive 3ES5K №879 with experimental traction converters VIP 4000D was manufactured at the enterprise in January 2018. 

PJSC Electrovipryamitel (Saransk) specialists together with the Irkutsk State University of Communication Lines scientists manufactured the converter with a reduced number of thyristor elements and discharged diodes. Specialists of JSC ‘LES’ (Locomotivnie Elektronnie Sistemi) designed software for managing this experimental converter. 

The newly installed engineering solution will increase power factor and reduce energy consumption during operation. Due to removal of 16 thyristors from each converter, the cost of serial electric locomotives will decrease by approximately 300 thousand rubles. 

The locomotive already passed acceptance testing at the plant and has been transferred for type testing to VELNII (The All-Russia Research and Development Institute of Electric Locomotive Engineering, also member of JSC Transmashholding). The electric locomotive is expected to confirm specifications, incorporated in the construction, during February-May 2018. 

Improved design will ensure increased energy efficiency and lower costs of the locomotive. 

A mass production of modified locomotives would be economically beneficial both for the enterprise and for the customer – JSC Russian Railways.
