Track circuit experimental system simulation insulation section

Abstract

The invention discloses a track circuit experimental system simulation insulation section and relates to a track circuit experiment device. The track circuit experimental system simulation insulation section comprises sand table tracks, a hollow coil, two tuning units and two loading coils. The two tuning units are respectively a first tuning unit and a second tuning unit. The first tuning unit is formed by a first coil and a first capacitor in a series-connecting mode. The second tuning unit is formed by the fact that a second coil and a second capacitor are connected in series and then are connected in parallel with a third capacitor. The first tuning unit is connected with low carrier frequency ends of the two sand table tracks. The second tuning unit is connected with high carrier frequency ends of the two sand table tracks. The distance between the two tuning units is 0.5-1.5m. The two ends of the hollow coil are connected in parallel to the middle portions of the two tuning units respectively. The two loading coils are connected in series to the same sand table track at the two ends of the hollow coil. According to the track circuit experimental system simulation insulation section, an uninsulated track circuit experimental system function can be conveniently achieved on a track sand table model, reliability is high, stability is good, and the track circuit experimental system simulation insulation section is suitable for experimental training teaching and professional training on courses relevant to railway communication signals.

However, as an experimental equipment for scientific research, vocational training and vocational teaching, there is still a vacancy in the training base of the electric power section and various railway colleges

The technical difficulty in the development of the ZPW-2000 series non-insulated frequency-shifting track circuit experimental system is the research and production of the parameters of the simulated electrical insulation joints. At present, there is no development and application of simulated insulating joints for the ZPW-2000 series non-insulated frequency-shifted track circuit experimental system.

The ZPW-2000 series of non-insulated frequency-shifting track circuit technology widely used in on-site railway signal systems is composed of a tuning unit, an air-core coil and a 29m rail. This technology has the following shortcomings: the structure of the electrical insulation section used on site It is relatively complex, large in size, not easy to install and debug, and the cost of components is relatively high. It does not meet the principle of "enough and applicable" for practical teaching in higher vocational education, and is not conducive to the overall design and development of the urban rail experiment training system.
