摘　　要：在冬季,长沙磁浮接触轨的覆冰会导致列车停运,目前国内外缺乏磁浮接触轨除冰的技术和经验。通过分析电脉冲除冰技术,根据磁浮接触轨的特点,提出了2种磁浮接触轨电脉冲除冰方案。同时研制了电脉冲除冰的电源装置,设计了磁浮接触轨除冰用的平面脉冲线圈。冲击摆试验结果表明:增大线圈尺寸、提高脉冲电压、减小线圈与目标物之间的间隙、提高目标物的电导率、增大涡流,能够有效增大脉冲力,提高除冰效率。据此优化了除冰装置的技术参数,进行人工气候室的模拟试验,从而证明电脉冲技术可以有效去除接触轨目标区域15 mm的雨凇覆冰。Icing on the contact rail of magnetic levitation line in Changsha city often occurs in winter,causing the line to be out of service.So far,the technical measures and experiences for de-icing of the contact rail of magnetic levitation line are lacking at home and abroad.By analyzing electro-impulse de-icing techniques and according to the characteristics of the maglev contact rail,we put forward two electro-impulse de-icing schemes of the maglev contact rail.At the same time,we developed a power supply device for electro-impulse de-icing and designed a plane impulse coil for de-icing of maglev contact rail.The impact pendulum test shows that the measures,such as increasing the size of the coil,increasing the impulse voltage,reducing the gap between the coil and the target,improving the electrical conductivity of the target,and increasing the eddy current,can increase the impulse force effectively and improve the de-icing efficiency.Moreover,the technical parameters of the deicing device were optimized.Then the simulation test of the artificial climate chamber was carried out.The results show that the electro-impulse technology can remove 15 mm glaze ice in the target area of the contact rail effectively.
