Definitions

  • the present invention relates to a method and a device for the increased heating of guideway elements, wherein at least one main heating element for regular heating is provided on at least one guideway element.
  • Track elements, especially switches, of rail-bound vehicles such as railways (full-length trains, branch lines, narrow-gauge railways) or trams are heated as needed to prevent freezing or blocking of moving parts by snow and ice, and thus to ensure operational safety .
  • Known point heaters are based on systems with hot water steam, gas heating or electrical energy.
  • Generic methods and devices are from the prior art, for example DE 198 32 535 C2 such as DE 198 49 637 C1 known per se.
  • These known electrical point heaters consist, among other things, of an electrical distribution with control and regulating devices for switching, controlling, regulating and monitoring each individual heating outlet, a weather-dependent control which activates the heating in ice and snow, and electrical heating elements on the rails of the points, which are warmed up and a Prevent freezing of the moving parts of the switches.
  • Snow and ice are detected by recording and evaluating air temperature and precipitation. If the actual rail temperature falls below a parameterizable target rail temperature, for example + 4 ° C, the entire point heater is switched on and as a result all points are heated with a delay due to the mass of the rails.
  • the rail temperature is regulated to a specific set rail temperature via a rail temperature sensor on a guide switch.
  • an energy management system which is designed for the optimal use of energy with a maximum connected load per turnout.
  • At least one active power ratio (La) is carried out.
  • the power ratio (La) is the ratio or quotient of the number of switched-on or switched-off heating outputs to the total number of heating outputs of the electrical point heating system. This is done activating or deactivating the heating outlets of the electric point heater according to a specific power ratio during each cycle time.
  • the specific active power ratio is adjusted as a function of a comparison of the actual control deviation with a stored maximum control deviation.
  • a disadvantage of this system is that when a maximum control deviation (XWmax) is exceeded, the at least one active power ratio is adjusted to 100%. As a result, there is no solution for the safe heating of the switches in extreme weather conditions and thus for larger control deviations.
  • a zone heater for reducing the connected load which divides the switch into prioritized zones such as the tongue tip and non-prioritized zones such as the tongue root or the locker.
  • the disadvantage of this system is that it is designed exclusively to reduce the connected load that is called up at the same time and not to increase the availability of the turnout in winter.
  • additional rail temperature sensors are required to control the individual zones for heating the individual zones. This is disadvantageous for the maintenance of the systems, since additional temperature sensors result in additional sources of error and, at the same time, cause increased maintenance costs.
  • the present invention is therefore based on the object of specifying a method for the increased heating of guideway elements, preferably of electrically heated switches, without increasing the connected load, and to provide a corresponding device, whereby a simple heating means a balanced heating of the relevant functional parts of guideway elements even in extreme weather conditions and can be implemented without additional sensors.
  • the invention advantageously leads to an optimal use of energy when heating track elements without having to increase the connected load, while at the same time heating the relevant functional parts in a balanced manner while ensuring the function of all track elements.
  • the outlay on installation and maintenance is kept low since, apart from the at least one secondary heating element (14), no additional elements have to be provided.
  • no additional sensors are required for the control and regulation of the auxiliary heating elements (14), since the heating time of the auxiliary heating elements (14) is determined on the basis of calculations.
  • no additional sensors are required for the maintenance and function monitoring of the secondary heating elements (14), since the sensors of the maintenance and function monitoring of the main heating elements (13) can be used in the heating breaks of the main heating elements (13).

At least one main heating element (13) for regular heating is provided on at least one guideway element (12) and at least one secondary heating element (14) is provided on at least one functionally relevant component of the guideway element (12).
  • reinforcementd means that a guideway element (12), or at least parts thereof, is additionally heated compared to the regular heating operation known from the prior art.

  • the track elements include switches, track barriers, signals, special track sections or level crossing systems.
  • route elements (12) are understood to mean, in particular, switches (all types of switches, such as simple switches, crossing switches, double-crossing switches, three-way switches, etc.). Turnouts include a number of functional elements, especially the stock rails, the tongue rails, the locker linkage, the support lugs and the sliding chairs, including any existing roller equipment.

  • This heating also only takes place if the heating power required on the guideway element (12) is greater than the heating power of the at least one main heating element (13) installed on the guideway element (12).

  • a homing run can be carried out, for example, or references from comparable route elements can be used.
  • the “temperature T0” designates the temperature of the respective guideway element at the time the main heating element is switched on.
  • “parameterizable target temperature Tsoll” is understood to mean that this temperature can be set automatically or manually to a specific value.
  • a current temperature setpoint Ta is then determined for each guideway element 12. This can be parameterized manually or calculated using mathematical equations depending on predefinable parameters and / or the current environmental parameters.
  • the main difference between the parameterizable target temperature Tsoll and the current temperature target value Ta is that the parameterized rail temperature Tsoll is fixed and the current rail temperature Ta is recalculated at any time.
  • the current rail temperature Ta calculated by any offsets or by mathematical equations may correspond to the parameterized target temperature.
  • the current temperature setpoint Ta can be determined in particular as a function of set parameters and / or of current and future weather conditions.
  • the determination of a current absolute control deviation ⁇ abs between a current temperature T0a of the route element 12 and the parameterizable target temperature Tsoll of the route element 12 is provided for at least one functionally relevant component of the route element 12.
  • the current temperature T0a of the guideway element 12 is the temperature of a specific part, for example a rail, measured by means of a sensor.
