为了探讨接触网对铁路集装箱中心站环境的影响,采用模拟电荷法对集装箱中心站空间电场进行计算;建立了正面吊的椭球体模型,计算了集装箱中心站空间电场对正面吊的感应电流.计算结果表明:距地面1500 mm处的电场强度峰值约为1.1 kV/m;正面吊正常工作和误操作时,感应电流最大值分别为0.15和0.62 mA,均不会对人体造成伤害.
In order to investigate the influence of catenary on the environment of railway container central station, the simulation electric charge method is used to calculate the space electric field of container central station. The ellipsoid model of front crane is established and the induced current of front crane is calculated by space electric field of container central station. The results show that the peak value of electric field at 1500 mm from the ground surface is about 1.1 kV / m. The maximal induced current is 0.15 and 0.62 mA respectively for normal operation and misoperation, which will not cause any harm to the human body.
