摘要
高速电气化铁道电磁干扰主要表现为电磁辐射污染与噪声干扰,其中对人体健康的负面影响和对电器设备的干扰是电磁辐射污染的主要危害。电气化铁道的噪声干扰源主要来自受电弓与导线的接触硬点,通过提高接触网和受电弓的质量降低噪声干扰。通过数学模型分析,就电气化铁道与军用雷达站的距离建立了大致对应关系。
High-speed electrified railway electromagnetic interference mainly as electromagnetic radiation and noise pollution, electromagnetic radiation pollution hazards including the interference of electrical equipment and the negative impact on human health this two aspect. Electrified railway noise sources mainly come from the contact point between the pantograph with lead wire, by raising the pantograph and catenary quality to reduce noise interference .Through mathematical model analysis , mili-tary radar station and electrified railway distance built roughly corresponding relationship.
