Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The invention realizes the safety basic backflow device of the audio standard track circuit in the railway station, and aims at the problem that the double-ended backflow connection method in the prior art can ensure the safe basic backflow, but cannot realize the broken track inspection of the track circuit. Safety type backflow reactor, the safety type backflow reactor can be applied to the audio standard track circuit section in high-speed and normal-speed railway stations, and realize the double-terminal backflow connection to ensure that the track circuit has the function of rail breakage inspection.

Abstract

The invention discloses a device for realizing the safe base reflow of a voice frequency system track circuit in a railroad station, which is used for realizing the safe base reflow of all the voice frequency track circuits in the high-speed and common-speed railroad station. The device comprises a safe type reflow electric reactor and a choke transformer; the safe type reflow electric reactor is connected with transverse connecting center wires of adjoining choke transformers at two ends of a mechanical insulating section in series; the adjoining choke transformers arranged the two ends of the mechanical insulating section are used for switching on traction current to pass through the mechanical insulating section; and the safe type reflow electric reactor is used for guaranteeing the broken rail inspection of the track circuit in the case of the realization of the safe base reflow.

Description

technical field [0001] The invention relates to the field of track circuits, in particular to a device for realizing the safe basic backflow of audio standard track circuits in railway stations. Background technique [0002] In the current high-speed and normal-speed railway stations, in order to prevent detours ("third rail" detours), unilateral backflow connections are used in the side line strands, commonly known as "one-end blocking", see figure 1 shown. The so-called "third rail" detour means that there is a circuit (bypass circuit) communication circuit besides the double-track transmission channel. Information can still be transmitted. Once the voltage of the track relay terminal in this section is too high, or even keep the excitation to pick up, the track circuit will lose the track broken inspection, which will pose a serious threat to driving safety. However, in the case of "blocking at one end", if the return channel is interrupted at the unilateral return pos...
