目前,97型25Hz相敏轨道电路正在我国电气化牵引区段及非电气化牵引区段广泛应用,在现场维修及施工中,发现一些信号维修及施工人员对97型25Hz相敏轨道电路的调整方法掌握不当,尤其是在电化区段预叠加ZPW-2000电码化的97型25Hz相敏轨道区段。一旦出现调整不及时,不仅延长了维修、
At present, the 97-type 25Hz phase-sensitive track circuit is being widely used in the electrified traction section and the non-electrified traction section in China. During the on-site maintenance and construction, some signal maintenance and construction personnel are found to master the adjustment method of the 97-type 25Hz phase-sensitive track circuit Improper, especially in the electrochemical zone pre-stacked ZPW-2000 code-based 97-type 25Hz phase sensitive track section. Once the adjustment is not timely, not only extended maintenance,
