Definitions

  • the most important part in the process of heating the railroad switches is melting snow out of the space between the stock-rail and the switch blade of the railroad switch as well as from slide chairs. It is achieved by heating the stock-rails (obligatory) and additionally by heating switch blades (optional).
  • the source of the electric heat for heating stock-rails of the railroad switches may be: a resistor heater, a self-limiting heater, an inductive heater.
  • the heater is fixed to the stock-rail nearby the slide chair and comes in contact with the lower surface of the chair.
  • zone A the inter-chair
  • zone A the inter-chair
  • the concept of zone A is understood to be the space between: between neighbouring chairs (approx. 2 cm away from each chair) and between the stock-rail, from the neck edge and the railroad switch blade, in the withdrawn state ( fig. 8 ).
  • FIG. 11 Another example of the heater 4, tested at Prostki station on 2 February 2012, is a non-conductive heater with a radiator installed in the railroad switch according to the invention, presented on fig. 11 and fig. 14 .
  • the heater used for the test was the heater 4 featuring the same design and electrical specifications as presented above; however, it additionally contained a radiator in the form of aluminium wire wound up to a 35mm wide coil, permanently fixed to the heating rod 8, in order to multiply the heating surface of this heater 4.
  • the results of the operational tests of the non-conductive heaters proved their assumptions to be correct.
  • the new type of the heater melts out snow from the space between the stock-rail and the switch blade much faster than the heaters used so far, even despite the little bit lesser power of the new heaters.
  • the stock-rail of the railroad switch according to the invention heated with non-conductive heaters gets heated up to much lower temperatures than while using standard heaters. It is preferable since overheating of the railroad switches during long-lasting heating negatively affects some of their components, e.g. insulating washers made of plastic.
  • the non-conductive heating of railroad switches according to the invention can be used to increase the efficiency of melting out snow and icings or to reduce the power of heaters or to accomplish both of these purposes.
