Definitions

  • the invention relates to a point heating system for maintaining the function of railway turnouts in frost and snow, which comprise at least one stock rail and at least one tongue rail and which at least one slide chair is associated with Gleitieneplatte.
  • Railway turnouts are, by definition, track constructions for track evaluation and association.
  • Turnouts are incorporated in track-guided traffic to branch railways, turn on or off sidings, to allow overtaking, to bypass sections, etc.
  • moving parts of a switch are moved back and forth, thus initiating a change of direction within tracks. It is important to have points with the highest possible availability. If things do not work properly, the operator incurs unreasonably high costs due to delay minutes and diversions or detours. Efforts are being made to replace high-maintenance switches with low-maintenance ones, but the heaters and lubrication points on drives, locks and hinges remain as maintenance points.
  • the effectiveness and cost-effectiveness of point heaters depends largely on the heat transfer between the heating cables and the switch parts to be heated. From the DE 1277290 It is known that between the radiators and the surfaces to be heated, a self-curing plastic composition is applied, which is mixed with metal in powder form for the purpose of achieving a good heat transfer. At the same time, the mass used is the mechanical support of the radiator to the Support rail parts.
  • the radiators are pipes through which a heated fluid flows.

  • the heating system according to the WO 2009/109664 A1 has shown that known devices for the winter operation of points do not ensure sufficient operational readiness in all weather conditions. This results in additional costs for the operator, in addition to the costs due to schedule deviations, as well as unreasonably high costs due to delay minutes and diversions or detours.
