图1JRWC2-25型相敏轨道电路电子接收器结构框图目前在全国数万公里的电气化铁路上,站内基本采用了25Hz相敏轨道电路,其稳定可靠的表现,已经成为电气化区段站内轨道电路的主要制式。1问题提出25Hz相敏轨道电路发送设备为25Hz铁磁分频器,接收设备为25Hz电磁式二元二位继电器。从 Figure 1JRWC2-25 phase-sensitive track circuit electronic receiver block diagram Currently tens of thousands of kilometers of electrified railway in the country, the station basically uses a 25Hz phase-sensitive track circuit, its stable and reliable performance, has become electrified section of the track circuit station The main standard. A question put forward 25Hz phase sensitive track circuit sending device is 25Hz ferromagnetic frequency divider, receiving device is 25Hz electromagnetic binary two relay. From
