INTERFERENCE OF STRONG ELECTROMAGNETISM ON COMMUNICATION SIGNALS OF THE RUNNING HIGH-SPEED TRAIN
Краткое описание
At present, the high-speed railway is mostly driven by electric power, so the high-speed railway communication accidents often occur because of the strong electromagnetic interference on the signal. To improve the efficiency of high-speed railway operation and ensure the real-time flow of communication signal, this study took lightning interference and traction power supply system interference as examples to analyze the structure parameters of communication tower and construct an equivalent model, to calculate different results under different interference, and the electromagnetic interference was evaluated. It was found that the loop overvoltage of the down lead which was the nearest to the lightning strike was the largest at the moment of a lightning strike at the communication site, and it was difficult to recover. The electromagnetism of the traction power supply system produced effect through traction return current, thus interfering signals. In addition, on the basis of the experimental results, several ways to prevent the interference of different electromagnetic signals were proposed to better apply the theory to practice.
