PROBLEM TO BE SOLVED: To provide a signal current measuring instrument for a DC track circuit capable of measuring a signal current that is a DC current, at each of measuring points while moving over an entire insulated rail (block section) in the DC track circuit, and a signal current measuring method.SOLUTION: A signal current measuring instrument 100 for measuring the signal current that is a DC signal of the DC track circuit, includes: a traveling part 1 which is placed on a rail step surface so as to be movable in a length direction of the rail; two contacts 2 which are provided while interposing a predetermined interval therebetween in a length direction of the traveling part and brought into contact with the rail for detecting a potential difference between the contact portions; and a signal processing part 3 for calculating and displaying a value of the signal current on the basis of the potential difference detected by the two contacts 2.

    【課題】直流軌道回路において、絶縁されたレール(閉塞区間)全体に亘って移動しながら各測定点で直流電流である信号電流を測定することができる直流軌道回路の信号電流測定器及び信号電流測定方法を提供する。【解決手段】直流軌道回路の直流信号である信号電流を測定する信号電流測定器100において、レールの長手方向に沿って移動可能にレール踏面に載置される走行部1と、走行部の長手方向に所定の間隔をおいて設けられレールに接触して当該接触部分の電位差を検出するための2つの接触子2と、2つの接触子2で検出された電位差に基づき信号電流の値を計算して表示する信号処理部3とを備える。【選択図】図1
