RailCorp Hunter Valley passenger DMUs

huntervalleycar

Product: Battery Chargers
Hunter Valley DMUs were built by United Group Rail in Broadmeadow, NSW. These trains run as a 2-car consist and each car has a pair of Schaffler battery chargers installed in the roof. An on-board generator provides 415 Vac three phase power to the battery chargers and this is converted to DC. The battery charging current and voltage are measured and fed back to the battery chargers in order to control the charging of the batteries and also supply the standing load on the battery bus. The battery chargers use an optimum charging algorithm of constant current, constant voltage and trickle charge modes. Each pair of battery chargers share the load and are able to take over the full load if the other fails. Maximum output current is 500 amps at 27.6Vdc.

RailCorp Xplorer and Endeavour Passenger DMU

4.2.3

Product: Battery Chargers
RailCorp maintain a fleet of Xplorer and Endeavour DMUs for use in outer metropolitan and regional areas of NSW. These trains run as 2 or 3 car consists and each car has a Schaffler battery charger installed in a locker. An on-board generator provides 415 Vac three phase power to the battery chargers and this is converted to DC. The battery chargers maintain a float voltage of 27.6Vdc on the battery bus which charges the batteries and also provides power to the standing loads. Maximum current for this battery charger is 150 amps.

MTR Hong Kong Converter Sets for Maintenance Wagons

MTRCwagon0004

Product: Converter Sets, Battery Chargers, Single Phase Inverters, Three Phase Inverters
MTR in Hong Kong use maintenance wagons to perform work on overhead lines on their network. The maintenance is performed at night in underground tunnels where diesel generators cannot be used. Schaffler converter sets are installed on the maintenance wagons to provide single phase or three phase power from 280 V battery banks. During the day back at the depot, the battery charger is used to recharge the batteries ready for another maintenance shift.

QR 2800 Class Locomotives

2800_qld

Product: Air Conditioner Power Systems, Three Phase Inverters
The 2800 Class locomotives are owned and operated by Queensland Rail. These locomotives have side-mounted all-in-one air conditioning systems that can be installed or removed via forklifts. Schaffler power systems have been installed in the air conditioning systems to provide power and control. The 74Vdc locomotive battery power is converted to 600Vdc which is then used by two three-phase inverters to control the speed of the compressor and provide power to the evaporator and control systems.

Cairo Metro

cairo_metro

Product: Three Phase Inverters
Cairo Metro use Schaffler three phase inverters as frequency converters. The input power is 250 Hz which is too fast for the on-board fan motors. The power is rectified and then inverted at 50 Hz which then can be used to drive the fan motors.

Pacific National NR Locomotives

4.2.3

Product: Single Phase Inverters, DCformers, DC:DC Converters
The NR Class locomotives are used for freight and long-distance passenger services on main lines throughout Australia. For the driver’s cab, Schaffler single phase inverters are used to provide 240 Vac 50 Hz power which can be used for standard appliances such as a kettle, hot-plate, refrigerator and microwave oven. This provides the crew with creature comforts on long journeys. The roof-mounted airconditioning system contains a Schaffler DCformer unit which converts the incoming 74Vdc to 600Vdc which is used by the airconditioning inverters and control system. A Schaffler DC-DC converter is installed in the braking control system.

CFCL Australia, VL Class Locomotives

AvteqVL

Product: DCformers, Three Phase Inverters
The Chicago Freight Car Leasing Australia VL Class Locomotives are built by AVTEQ in Melbourne, VIC. The airconditioning system that serves the driver’s cab is powered by a Schaffler DCformer and three phase inverter. The DCformer converts the incoming 74Vdc from the locomotive battery bus to 600Vdc. This is used by the three phase inverter to power the compressor of the airconditioner.

MTR and KCRC Hong Kong

4.2.3

Product: Three Phase Inverters
MTR and KCRC Hong Kong had a requirement for inverters for ventilation fans. These were to supply power to the emergency fans whilst passengers were evacuating. The frequency of the inverters would slow as the voltage of the batteries dropped.

RailCorp Tangara

Product: Three Phase Inverters
RailCorp Tangaras were fitted with inverters for the emergency ventilation system. Three phase inverters were used to convert 110Vdc to 70Vac at 20 Hz. This provided power for the ventilation fans in emergency situations as passengers evacuated.

VLine N-Car passenger cars

Product: Battery Chargers
Schaffler developed a new battery charger for use on VLine’s N-Car passenger cars. This battery charger is underslung. The unit is a dual charger taking 240 Vac input and charging the on-board lead-acid and NiCad batteries simultaneously

Yarra Trams

Product: Single Phase Inverters, Capacitor Banks
Yarra Trams operate the tram system in Melbourne, Australia. A number of older trams have been upgraded with air conditioning in the driver’s cab. Schaffler single phase inverters have been installed in these trams to provide power for the air-conditioning units. The inverters convert the overhead 600Vdc supply to a sinusoidal 240V 50 Hz. When trams cross an intersection there is a break in the overhead power supply. Typical loss of power lasts 100-200 ms. Capacitor Banks are installed to maintain the DC supply voltage for this short time. The inverter operation is thus uninterrupted.
