Embodiment 1

[0034] Embodiment 1: as figure 1 Shown in Fig. 1 is a power regulator for a railway turnout snow melting system, a power regulator that can meet the power demand and also meet the heating area of ​​the turnout, but has little effect on the snow melting effect.

[0035] Power regulation module; the present invention is installed in the isolation transformer 1, the power supply is AC 220V, and the power indicator lights up after the power supply. In order to meet the requirements of the railway track circuit, the regulator 2 is divided into a first output 7 and a second output 8 to ensure isolation. The output principles of the first output 7 and the second output 8 are the same.

[0036] The first output 7 and the second output 8 are respectively divided into four loops, and the first output 7 and the second output 8 are respectively composed of white-red loop, white-blue loop, white-green loop, and white-yellow loop. Each circuit can carry several electric heating elements (t...

Embodiment 2

[0072] Embodiment 2: as figure 1 As shown in the figure, a power regulator of a railway turnout snow melting system is installed on the secondary side of the isolation transformer, the power supply is AC 220V, and the power indicator light is on after the power is supplied. In order to meet the needs of the railway track circuit, the isolation transformer needs to use double-side output, so this regulator is divided into two outputs like the isolation transformer to ensure isolation. The principles of the two outputs are the same. Each output is divided into four circuits, and each output is composed of a cable in the secondary side of the transformer and four red, blue, green and yellow cables of the regulator. Each circuit can carry several electric heating elements (when installing and wiring, ensure that each circuit relatively balanced load).

[0073] figure 2 For the power supply circuit of the power regulation module, the 220V50HZ power supply is changed to 6V throug...

Abstract

The invention provides a power regulator and regulating method of a railway turnout snow-melting system, and belongs to the technical field of electric appliances. A power regulating device is mountedin an isolating transformer or an electrical control cabinet. A power supply is AC 220V, and a power supply indicating light lights up after power supply. In order to meet the requirement of a railway track circuit, the regulator is divided into first via output and second via output for ensuring isolation, and output principles of the first via output and the second via output are the same. Thefirst via output and the second via output are separately divided into four loops, the first via output and the second via output are separately composed of the four loops of a white-red loop, a white-blue loop, a white-green loop and a white-yellow loop, and each loop can be provided with a plurality of electrical heating elements. According to the power regulator and regulating method of the railway turnout snow-melting system, a working mode of circularly switching is adopted, the integral efficiency is reduced. Each loop of each via of output is cut off for three seconds (the duration canbe adjusted to one to three seconds or more than three seconds) every time in order, and therefore, a load on the transformer cannot simultaneously enter the working state.

Description

technical field [0001] The invention relates to a power regulator and a regulation method of a railway turnout snow melting system, belonging to the technical field of electric appliances. Background technique [0002] Electric heating turnout snow melting system equipment has become one of the more critical auxiliary equipment for the normal operation of railways in winter. As the equipment and technology of electric heating turnout snow melting system become more and more perfect, the products become more mature, and the configuration becomes more and more reasonable. In order to meet the continuous improvement of equipment requirements for railway speed increase, it is extremely important to reinforce the deficiencies in the snow melting configuration of early turnouts, and it is already in progress. [0003] Reinforcement means that the heating area of ​​electric heating elements needs to be increased, so the number of electric heating elements needs to be increased, so...
