电气化铁道牵引系统接地,由于它的部分设备为隐蔽工程,在施工单位或运营单位相对电气设备或牵引电流的回路往往重视程度不够,因此,牵引系统接地问题给牵引供电系统带来了不少的安全隐患,甚至造成较为严重的事故。随着牵引供电系统牵引变压器容量的不断加大,因为牵引系统接地出 Electric railway traction system grounding, because some of its equipment for the concealed works, construction units or operating units in the relative electrical equipment or traction current loop often less seriously, therefore, the traction system grounding to the traction power supply system has brought a lot of Security risks, and even cause more serious accidents. With the traction power supply system traction transformer capacity continues to increase, because the traction system is grounded
