IPT® (Inductive Power Transfer)
Number of vehicles
Generally the basic function of IPT-Rail systems is the same as that of other Inductive Power Transfer systems. But there are some additional or specific aspects to consider.
Because vehicles are usually rail guided here and an elevated installation of the cable is possible it becomes also possible to use E-shape pickups.
In applications with traveling track segments, i.e. switches in electric monorail systems, the experience with inductive power transfer can be used to supply such track segments inductively with energy. Wearing cable chain solutions or other similar solutions become second choice. If the idea of inductive power transfer is consequently realized it becomes even possible to feed so called safety zones in front of switches or lifts so that there is only power transfer possible when the segment is in position. To realize this no extra feeds or external control is necessary.
Naturally contactless, inductive power transfer systems can also replace other conventional solutions, as cable chains or conductor rails in skillet lines, skids or in transfer cars if there are certain requirements on the solution, for example if voltage arcs at rail ends shall be avoided or if the access for maintenance underneath skillet platforms is very limited.
