摘要:
地铁系统中空心电抗器产生的漏磁场会对周围环境产生电磁污染,因此防磁板的磁屏蔽作用至关重要。文章建立了空心电抗器的三维有限元模型,对比分析了有无防磁板时空心电抗器产生的漏磁场在车厢内的分布情况,研究了防磁板的材料和尺寸对车厢内不同位置磁场强度的影响。最后对设计的防磁板进行了上车试验。试验结果表明,所设计的防磁板满足车厢内部地板上方30 cm处的气隙磁通密度最大值小于0.8 mT的要求。
Abstract:
Leakage magnetic field generated by the air-cored reactor will produce electromagnetic pollution in the metro system, therefore, magnetic shielding of the antimagnetic plate is of crucial importance. First, the three-dimensional finite element model of the air-cored reactor was built. Second, the distribution of the leakage magnetic field without antimagnetic plate was analyzed and compared with the results with antimagnetic plate. In addition, the influences of the antimagnetic plates with different material and different size on the flux density at the different height inside subway cars were investigated. Finally, the on-board test of the designed anti-magnetic board was carried out. The experimental results showed that the designed anti-magnetic board met the requirement that the air gap flux density at 30 cm above the floor inside the compartment was less than 0.8 mT.
