电力机车是从电力牵引接触网上获取工频(50周)25千伏电压的电能,用牵引电动机做为动力的机车。据调查牵引接触网周围是存在着较强的工频电场。但是电能从接触网上传至电力机车内的装置后,是否还存在着电磁场的危害?对于这一问题,国外尚无报导,国内虽对电力机车劳动条件及其对乘务员健康状况,曾做了一些调研,但是否存在电磁场的危害问题,都是作为尚待研究的问题。为了保护乘务员身体健康,消除思想顾虑,必须要搞清楚这问题,方能采取有效措施,促进铁路运输牵引
Electric locomotive is from the electric traction contact network access frequency (50 weeks) of 25 kilovolt voltage power, traction motor powered locomotive. According to the survey traction catenary around there is a strong power frequency electric field. However, whether electricity still exists the danger of electromagnetic field after the electric power is transmitted from the contact network to the device inside the electric locomotive? There is no report about this issue in foreign countries. Although there are some reports about the working conditions of electric locomotives and the health status of flight attendants in China, Research, but whether the existence of the dangers of electromagnetic fields, are as yet to be studied. In order to protect flight attendants’ health and eliminate their thoughts and worries, it is necessary to clarify this issue before effective measures can be taken to promote the traction of railway transportation
