Modernization steps:
- replacement of the transformer's tap changer with static converters based on thyristors or IGBTs
- replacement of the heavy-duty contactors with semiconductor-controlled rectifiers;
- use of static converters for the supply of auxiliary services;
- replacement of the piston compressor with a rotary screw compressor;
- installation of an electronic wheelslip protection system that improves traction force;
- installation of a DSP-type traction control computer, which allows the isolation of any traction motor in the event of a fault and their diagnosis;
- upgrade of the battery charger
- installation of a central computer for locomotive control and malfunction diagnosis
- using a cab monitor to display the locomotive status;
- reinforced glass based dashboard
- using a controller for speed control and traction current;
- installing an air conditioning system for each driver cab;
The technical solutions are based on the customer's needs and on the locolmotive's characteristics.
