摘　　要：牵引变电站把区域电力系统送来的电能,根据电力牵引对电流和电压的不同要求,转变为适用于电力牵引的电能,然后分别送到沿铁路线上空架设的接触网,为电力机车供电。牵引变电站接地装置是确保电气设备正常工作和人身、设备安全的重要技术措施,应该高度重视。针对电气化铁路供电系统接地装置设备投入运行后,因环境原因造成频繁跳闸,进行原因分析,并制定了相应的对策,经过设备排查、监测、整治,极大地提高了供电质量,保证了设备的安全运行,效果显著。The traction substation transforms the electrical energy sent from the regional power system into electrical energy suitable for electric traction according to the different requirements of current and voltage for electric traction,and then sends it to the contact network erected over the railway line respectively to supply power to the electric locomotive.Traction substation grounding device is an important technical measure to ensure the normal work of electrical equipment and personal and equipment safety,should pay great attention to.For the electrified railway power supply system grounding device equipment into operation,due to environmental reasons caused by frequent tripping,to analyze the causes,and develop corresponding countermeasures,after the equipment investigation,monitoring,rectification,greatly improve the quality of power supply,to ensure the safe operation of equipment,the effect is remarkable.
