2 Power supply for pre-heating and pre-cooling Efficient power management for parked rail coaches and railcar trainsets at any track preheating, airconditioning and freeze protected parking A.S.T. Power management systems ensure the power supply for preheating, airconditioning and frost protected parking of rail coaches and railcar trainsets. The systems have been developed in cooperation with the former BZA Munich and the DB Energie in Frankfurt and can save up to 40% of energy compared with manual operated preheating or airconditioning. In doing so the parked train sets are preheated or airconditioned at a particular time at which the coaches have to be well-temperatured for the entering passengers. The systems are installed mainly at interchange stations or formation yards. At depots and maintenance workshops the systems supply coaches, traction units or high speed trains with energy. Due to the unitized setup the system can be easily extended by new branch lines. Switching operations and energy consumption at the specific connection points are captured permanently by the control system and therefore can also be analysed and allocated. 2

3 Operation mode The supply power is either taken from the overhead contact line (11 kv, 15 kv or 25 kv) or if the track line is not electrified from the public utility (10 kv or 20 kv). In order to transform the energy to the required supply voltage (330 VAC, 1000 VAC, 1500 VAC) the energy is fed via a medium voltage switch gear with a vaccum circuit breaker to transformers. The distribution switchgear provides the tranformed current via power contactors by cables to the cable connection boxes. From the cable connection boxes with predetermined breaking points the energy is supplied to the coaches and railcar trainsets with a flexible rubber hose cable using a RIC plug connection. The operation is done at the control pillar next to the track. There the operator choses the designated operation mode and enters the departure time of the trainset at the built-in µp time switch. Depending on the outside temperature the time switch computes the optimal turn-on instant for the power contactor or clocks the power contactor in order to prevent the coaches from frost at temperatures below the freezing point. The total system is controlled by a process computer-aided control system. There all actions of the system are controlled, monitored and recorded. The current operation states and the activity memory can be read out at any time via modem and analysed by software. 3

7 Our scope of supply and services + Planning and realization Our scope of work includes planning, development, delivery and ready to operate assembling of the system. The system is set in operation and handover to the customer. In cooperation with selected, rail experienced partners we serve underground construction, cabling and sounding. + Experience A.S.T. Power management systems for rail vehicles are on duty for more than 35 years. We installed already over 215 systems with a nominal total power of 320 MVA and about 2050 power outlets. Concering the system built before 1984 another 2000 power outlets have been equipped with our energy saving outside temperature depending control pillars. + Service Using modules and standard subassemblies a cost-effective storage can be realized both at the customer s depot and our company. + Maintenance Of course we can carry out the necessary maintenance work, including inspection and adjustment of the protection relays and inspection of the safety precaution.
