PROBLEM TO BE SOLVED: To provide a track short circuit device capable of making a track circuit detect on-rail without operating a railroad crossing even in a rail track in which a non-insulated type track circuit is installed and the frequency of the track circuit is set close to the frequency band of the railroad crossing control signal.SOLUTION: The track short circuit device is provided in a pair of electrodes (27) connected electrically to a pair of rails respectively, and in a signal path (L1) connecting the pair of electrodes and comprises a frequency filter (19) for passing a signal of a passing frequency and reducing the passage of signals of other frequencies, a current sensor (3) for detecting the current flowing through a rail coming close at least one rail of the pair of rails, a current frequency measuring part (11) for measuring the frequency component of the current detected by the current sensor (3), and a control part (13) for setting the passing frequency of the frequency filter based on the measurement result of the current frequency measurement.SELECTED DRAWING: Figure 2

    【課題】無絶縁形の軌道回路が設けられ、軌道回路の周波数が踏切制御の信号の周波数帯の近くに設定されている線路においても、踏切を動作させずに軌道回路に在線を検知させることのできる軌道短絡装置を提供する。【解決手段】この軌道短絡装置は、一対のレールにそれぞれ電気的に接続される一対の電極(27)と、一対の電極を結ぶ信号経路(L1)に設けられ、通過周波数の信号を通し、他の周波数の信号の通過を低減する周波数フィルタ(19)と、一対のレールのうち少なくとも一つのレールに近接されて一つのレールに流れる電流を検出する電流センサ(3)と、電流センサ(3)により検出された電流の周波数成分を計測する電流周波数計測部(11)と、電流周波数計測の計測結果に基づいて周波数フィルタの通過周波数を設定する制御部(13)とを備えている。【選択図】図2
