APPLICATION

The ENI-PL3000/130/S2 is a locomotive auxiliary converter intended to output 3 x 400 V, 50 Hz sine AC voltage and 24 V DC voltage for electrical lines aboard retrofitted EP-07 rail locomotives. This is a UIC-600 compliant HV powered device. When the vehicle is stationary, the converter can recharge the battery bank via 230 V, 50 Hz power supply connector.

DESIGN

The device is built as a single cabinet made of 8 mm thick aluminium sheet and with extra rack brackets inside. The cabinet enclosure is preserved by powder coating for improved resistance to operation and environment. The device enclosure features lifting lugs.
The device requires forced air circulation to work properly, and this is assured by the integrated fans fed by one of the three-phase outputs. The air intake grilles with dust filters are installed at the bottom of all cabinet doors, whereas the air exhaust grilles are located on the converter cabinet back wall at 1870 mm of height.
The cabinet size, the installation method and the electrical connections of the converter have been designed specifically for floor mounting in the retrofitted locomotives. The AC output and control outputs are Harting multipin connectors. The 3000 VDC and 24 VDC inputs are screw terminals located inside of the enclosure.
All electrical power processing components are separated from the enclosure and PN-EN 60077-1:2002 insulation tested.

OPERATION

The converter transforms the railway contact system voltage (3000 VDC) into stabilised output voltage:

  • Seven 3 x 400 V outputs with different power output and frequency values for locomotive AC loads (including compressors and fans).
  • 27.6 VDC for locomotive DC loads and the battery bank.

The device can also be supplied from stationary 230 V, 50 Hz power sources. This trackside power supply mode facilitates battery bank recharging without feeding the converter with the 3000 VDC contact system voltage. In the trackside power supply mode, the converter output current is limited to the maximum charging current of the battery bank, and all other converter modules are offline, including the master control module which handles data exchange over CAN.
The converter control systems ensure AC and DC output voltage stability independently from any HV power supply variations or locomotive loads, and make the converter immune to the effects of overloads or shorting that may occur in the locomotive electrical installation. Each converter module features an individual and dedicated control system supervised over CAN by the master control module which handles proper operation, configuration, diagnostics and communication with the locomotive on-board controller. All control systems are based on microprocessor control units. The converter enables diagnostic functionalities and communication with other locomotive on-board equipment over CAN. The diagnostic systems monitor the parameters and performance of all converter components.
The converter also features a spare AC output (AC7). If any other output fails irrecoverably, the contactor system will switch over to AC7 and assures continued power output from the converter.
