轨道电路是利用铁路线路的钢轨作为导体传递信息的电路系统,是钢轨线路和连接于其始端及终端的器械总称,是铁路列车运行自动控制与远程控制系统的基本组成单元。随着科学技术的不断发展,铁路运输生产日益扩大,轨道电路也在不断地更新、发展和完善,轨道电路的制式越来越多。在交流480轨道电路、交流电码计数轨道电路基础上,发展了抗干扰能力较强且适应电力牵引区段
Track circuit is the use of rail lines as a conductor of steel transmission circuit information system is a rail line and connected to the beginning and end of the general term for the instrument is the automatic control of train operation and remote control system is the basic component unit. With the continuous development of science and technology, the railway transportation has been expanding in production and the orbital circuit has been continuously updated, developed and improved, and the orbital circuit has become more and more standardized. On the basis of AC 480 track circuit and AC code count track circuit, it has developed a strong anti-interference ability and adapts to the electric traction section
