摘要:
建立了雷电流波形、动车组车载避雷器,以及车体电阻电感等效电路模型,研究了动车组车体车顶与车底之间、车底与轴端之间雷电过电压分布规律; 根据过电压产生机理提出了一种新的接地系统设计方式,并分析了新接地方式下,车体雷电过电压的变化特点。研究结果表明,动车组车体雷电过电压波形呈震荡衰减变化趋势,车顶-车底之间车体雷电过电压要大于车底-轴端之间雷电过电压。新接地系统对车底-轴端之间雷电过电压的影响较大,其过电压幅值最大衰减幅度达到其原值的27%。
Abstract:
In this paper, a lightning current waveform equivalent circuit, an EMU arrester model and a car body resistance inductance equivalent circuit are built. Additionally, the distribution law of lightning overvoltage between the top and bottom of the EMU car body and between the vehicle bottom and the axle ends are studied. According to the overvoltage generation mechanism, a new grounding system design method is proposed, and the variation characteristics of the vehicle body lightning overvoltage under the new grounding mode are analyzed. The research results show that the lightning overvoltage waveform of the EMU car body has an oscillating attenuation trend, and the lightning overvoltage between the roof and the vehicle bottom is greater than that between the vehicle bottom and the axle end. The new grounding system has a greater influence on the lightning overvoltage between the bottom and the axle end, and the maximum attenuation amplitude of the overvoltage amplitude reaches 27% of its original value.
