摘要
针对电气化列车运行过程中,接触网与受电弓之间发生离线引起的电磁干扰问题.利用一套弓网电弧电磁噪声实验系统,在不同压力、速度和电流条件下,开展了64组弓网电弧传导噪声实验.本实验系统由电波暗室、弓网电弧产生装置和弓网电弧检测系统组成,能够实现对接触电压、接触电流、接触温度和接触压力进行采集.实验结果表明,当接触电流和滑动速度一定时,随着压力的增加,电流信号中的断流率减小,直流分量上升;当接触电流和接触压力一定时,随着滑动速度的增加,断流率增加,直流分量下降.
With the increase of electric locomotive＇s speed, the offline which caused electromagnetic interference of catenary and pantograph has become an important factor restricting the development of high-speed railway. In order to study the theory of electromagnetic compatibility in the pantograph-catenary system, an electromagnetic noise experimental system was developed. The device consists of the electric wave darkroom, the device of pantograph-catenary arc and the arc detection system, which can acquire the contact voltage and contact current collection, contact temperature and contact pressure. Different contact force, contact current and sliding speed conditions, 64 groups of electromagnetic noise experiments were conducted. It uses the FFT to analyze the DC component. Experimental results show that when the sliding velocity and contact current is constant with the increase of pressure, the rate of current interruption is decreasing in current signal, and the DC component is going up. When the contact current and contact pressure is constant with the increase of sliding velocity, the rate of current interruption is increasing in current signal, and the DC component is going down.
