摘要: 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.Abstract: The charge simulation method was applied to calculate the space electric field in railway container center stations to investigate the space electric field caused by the catenary and its effects.An ellipsoidal model for a reach stacker was put forward,and induced current of the reach stacker by the space electric field was calculated.The calculational results indicate that the peak value of electric field intensity at a height of 1 500 mm away from the ground is about 1.1 kV/m.When a reach stacker works normally,the induced current is about 0.15 mA,while it is about 0.62 mA when the reach stacker works falsely.The above results show that the induced current is not enough to harm people working at that area under the two conditions.
