随着铁路电气化在我国的发展,电力牵引所产生的电磁场对人体健康有无危害,已逐渐引起职业卫生工作者的重视。铁道部劳卫所等单位对铁路牵引变电所、接触网下及电力机车内的工频电磁场强度进行测试,并调查工人的健康状况,结果显示:在1～3.5kV/M,0～398安/米的电磁环境中作业不会对工人构成职业性危害。 With the development of railway electrification in our country, the electromagnetism field generated by electric traction has no harm to human health, which has gradually attracted the attention of occupational health workers. The Ministry of Railways, Labor and Social Security, and other units tested the power frequency electromagnetic fields in railway traction substations, contact lines and electric locomotives and investigated the workers’ health status. The results showed that at 1 ~ 3.5kV / M, 0 ~ 398 An / m electromagnetic environment in the homework will not pose a occupational hazard to workers.
