Embodiment Construction

[0091] In heating operation over a plurality of cycle times Zt, when the power ratio L is the same, the power corresponds to the product of the power ratio L and the installed connected load P of all heating elements 7 of the electrically heated point snow melting system.

[0092] The term "power ratio" will be explained in more detail below.

[0093] The maximum number of power ratios L is produced by reducing the number of heating output circuits 6 of the electric heating switch snow melting system by one. However, this maximum number is limited at power ratios of less than about 35% because the switches 12 are heated very little and for economical reasons in electrically heated switch snowmelting systems with more than 15 switches 12 .

[0094] The power ratio L can be switched during heating operation. The syntax of the power ratio L is derived from the duty cycle of the heating time and cooling time.

[0095] For all heating output circuits 6 of the electric heating tur...

Abstract

The invention relates to a method for energy management of an electrically heated turnout snow melting system, wherein a cyclically continuous cycle time (Zt) is formed during heating operation and is dependent on the number of switched on and off heating output circuits (6) At least one power ratio (L) is formed for each cycle time (Zt), the heating output circuit (6) is activated in a cyclically progressive mode of operation, thereby implementing at least one active power ratio (L a ), wherein by means of the time profile of the track temperature (X) and / or monitoring of the control deviation xw on at least one switch (12) n To adjust, in terms of weather-related heating demand (Hz) for at least one switch (12), calculate the predetermined track set temperature (X) until reaching the switch (12) s ) theoretical heating time, where over the parameterizable heating time (t auf ) to increase the active power ratio (L a ), where after and / or before each cycle time (Zt), the corresponding track temperature (X) of at least one switch (12) is compared with a predetermined track set temperature (X s ) for a comparison, wherein in the evaluation of the comparison the change is made in such a way that the overheated heating output circuit (6) is switched off in favor of the underheated heating output circuit (6) for the corresponding cycle time (Zt) Assignment of on and off heating output circuits (6). In addition, the invention also relates to a device for energy management of an electrically heated turnout snow melting system.

Description

technical field [0001] The invention relates to a method and device for energy management of an electrically heated turnout snow melting system. Background technique [0002] Track components of railways, especially the switches, are heated as required to prevent moving parts from freezing or becoming clogged with immersed ice and snow especially in winter, thus ensuring work safety. Known point heating installations are based on systems with hot steam, gas heating or electrical energy. At the same time, the economic benefits of such turnout heating equipment are largely determined by purchase costs, maintenance costs, and energy costs. [0003] The invention relates to a method and device for energy management of an electrically heated turnout snow melting system. Such a turnout snow melting system comprises at least one turnout with fixed base rails and movable tongue rails and seal frame linkages and a power distribution device with a heating output circuit for supplyin...
