Electric heating snow melting method for railway switch
The invention relates to an electric heating snow melting method for a railway switch. The electric heating snow melting method is characterized in that the total heating power is adjusted by judging and controlling the length of heating time according to an acquired heating temperature parameter of a steel rail sensor by modifying a system control software, when the ambient temperature is high and the wind power is small, the temperature parameter acquired by the steel rail temperature sensor shows a fast temperature rising, and the heating time for reaching the temperature upper limit value is short; when the ambient temperature is low and the wind force is large, the temperature parameter acquired by the steel rail temperature sensor show a slow temperature rising, the heating time for reaching the set temperature upper limit value is long, and the heating power of a snow melting system is automatically adjusted according to the temperature on the rail surface. The power is controlled and adjusted by utilizing the time according to the variation of the wind force and the ambient temperature, and a purpose of reducing the energy consumption can be realized.
