摘　　要：分路不良是轨道电路常见的故障，站内25HZ相敏轨道电路分路不良在使用中尤为突出，文章通过分析造成25相敏轨道电路分路不良原因，论述3v化25Hz相敏轨道电路的原理和优势，给出了在站内既有线上各种制式25HZ相敏轨道电路改造为3V化的方案。Bad shunting of tack circuit is common faults in signaling. The bad shunting of station of 25HZ phase de- tecting track circuit is in particularly prominent. Through the analysis to 25HZ phase detecting track circuit cause bad shunting reason, this paper discusses theory and advantages of 3v 25 HZ phase detecting track circuit, and proposes reform scheme the various stand in the line type 25HZ phase sensitive track circuit transformation for 3V.
