针对目前矿用电力机车动力电源本身产生较强的电磁辐射,对周围环境造成较为严重的电磁干扰,同时由于所处现场环境多种电磁干扰也会对电力机车和蓄电池管理系统可靠运行造成隐患,在实验室模拟工况和现场多种工况下提取电力机车用开关电源、发动机控制器和机车发动机等主要干扰源电磁辐射特征,结合已有煤矿井下电磁干扰的产生机理和干扰特性的研究结果,分别制定出相应的抗干扰方案。通过相关方法的研究提高煤矿井下车载电源对周围电磁环境的抗干扰能力,为丰富提高矿用电力机车的电磁兼容性、抗干扰能力和进一步完善相关行业标准提供理论依据。
In the light of the fact that the power supply of mine electric locomotive itself produces strong electromagnetic radiation and causes serious electromagnetic interference to the surrounding environment, various electromagnetic disturbances in the scene of the locomotive also cause hidden trouble for the reliable operation of the electric locomotive and the battery management system, Extracting the electromagnetic radiation characteristics of main interference sources such as switching power supply, engine controller and engine of electric locomotive under simulated laboratory conditions and various working conditions in the field, combined with the research results on the generation mechanism and interference characteristics of the existing underground coal mine electromagnetic interference , Respectively, to develop a corresponding anti-jamming program. Through the research of related methods, the anti-interference ability of underground vehicle power supply to the surrounding electromagnetic environment is improved, which provides theoretical basis for enriching the electromagnetic compatibility, anti-interference ability of mining electric locomotives and further improving relevant industry standards.
