EK-15 electric locomotive
Was developed in 2005 under the project of Special Designer’s bureau of JSC “Elmavalmshenebeli”. Electric locomotives EK-15 are successfully operated on the coke batteries of JSC “Severstal”.
We work on signing delivery contracts with
EK-14U are successfully operated on the coke batteries of JSC “MECHEL”, well-known metallurgical concern MITTAL STEEL (
ЕК-15– coke-quenching electric locomotive of new generation. Engine-driver’s conditions are more comfortable, mechanical and electrical parts are divided on blocks. The standard structure now includes conditioning system of working area. It is intended for temperature rate from -50 up to +60'C. High-sensitive thermometer is installed on the locomotive to control the transported coke temperature. Electric locomotive control system, transformers and more comfortable size essentially differ EK -15 from its predecessor. (The size can be developed for the customer’s coke battery).
Electomagnetic rheostatic braking was applied to EK-15 for the first time. It provides almost complete instant stop of the train to within +10 sm. As a result the constant usage of electropneumatic brake is not necessary. Owing to it the significant part of operational costs is reduced, and the safety level during the movement increases.
Out-of-date electrical devices, which were used in converting units for power supply of anchor shackles and excitation circuits of tractive motors, are turned to new elemental basis. Electrical part of control system is made with the use of semi-conductor technics (thyristors, integral circuits, etc).
Instead of two bulky controllers, applied on electric locomotive EK-14U, reliable compact controller is engineered and placed in the locomotive-driver panel. Locomotive power circuits and control circuits are simplified, the reliability of work is raised. For the additional increase of operation reliability stabilized voltage source of 50V of direct current and continuous power source of control system is introduced. The application of enclosed engines also reduces the quantity of failures.
Distant control system is applied for traction and rheostatic braking. There is a possibility of automatic control, standard interface with necessary program service. The upkeep of permanent values of traction force and creeping speeds is totally automatic.
Necessary equipment for radio traffic is installed. LAND-SOLO type pyrometers are installed on door taking off machines for the coke temperature measuring system.
Emergency operation circuit is improved. Distant block switch-off is provided in case of traction engine or transformer breakage.
