摘要
当前电气化铁路主要包含直接供电、吸流变压器供电、自耦变压器供电3种牵引供电方式,通过对3种牵引供电制式介绍,对不同供电方式影响铁路信号设备所产生的干扰进行原理性说明,分析产生不平衡电流的原因,并根据产生不平衡电流的众多原因,对轨道电路防护不平衡电流干扰所采取的措施进行详细研究。
There are mainly three traction power supply methods for current electrified railways, including direct power supply, booster transformer power supply and autotransformer power supply. Through briefly introducing three kinds of traction power supply systems, this paper introduces the principles of interference to signal equipment in different power supply modes, analyzes the causes of unbalanced current, and studies the measures to prevent track circuits against unbalanced current interference according to the causes of unbalanced currents.
