The AC / DC converter converts voltage and current from AC to DC, the divider divides the current value from the voltage value to obtain the short-circuit resistance, and the display shows that the short-circuit is normal when the short-circuit resistance is below a certain value. If the short-circuit resistance obtained by dividing the rail-to-rail voltage and the short-circuit current at the time of short-circuiting is equal to or less than a certain value, it has a function of displaying a normal short-circuit. Furthermore, the short circuit between rails and the voltage terminal for measuring the voltage between rails are housed in one molded product,
In order to measure the rail-to-rail voltage and the short-circuit current, the switch switches the input and output of the AC / DC converter simultaneously according to the instruction of the switch controller. The switching controller controls the switching device, and the level holding circuit holds the DC level when the switching controller is selected. Also, since only one AC / DC converter for switching the voltage and current from AC to DC is sufficient, the circuit configuration is simplified.

As shown in the figure, the short-circuit device short-circuits between the rails with a short-circuit 3 and a short-circuit line 4. Measure the rail-to-rail voltage and short-circuit current to ensure that the short-circuit has occurred, determine the short-circuit resistance at which the short-circuit is actually short-circuited, and indicate that short-circuiting is normal if the value is below a certain value.

器７で直流に変換する。The rail-to-rail voltage is measured by bringing the voltage terminal 5 into contact with the rail, and the short-circuit current is measured by a current sensor 6 inserted in the short-circuit line 4. The voltage and current components are converted to DC by an AC / DC converter 7.

測定できないので交流／直流変換回路７に信号成分以外
の雑音成分を除去する帯域フィルタを入れておく。In the track circuit in the electrified section, the electric vehicle current also flows on the rail in a superimposed manner, so that the voltage / current component to be measured contains many noise components other than the signal component, and the short-circuit resistance cannot be measured accurately. The circuit 7 is provided with a bandpass filter for removing noise components other than signal components.

か否かを判定することができる。The obtained short-circuit resistance is input to the display 9 , and when the short-circuit resistance is equal to or less than a predetermined value, a display of normal short-circuit is displayed.
When the short-circuit resistance is larger than the set value, a short-circuit failure is displayed or no display is made. In this way, when the rails are short-circuited by the track circuit short-circuit device, it is possible to determine whether or not the short-circuit is normal.

きくなって短絡不良を検出することができる。Since the short-circuit and the voltage terminal are independently connected to the rails of the track circuit, if the short-circuit between the rails due to the short-circuit is not normal and the contact resistance is large, the voltage between the rails is large, and Since the short-circuit current is measured to be small, the short-circuit resistance obtained by dividing the rail-to-rail voltage by the short-circuit current increases, so that a short-circuit failure can be detected.

It will be easier.

Two components are required to measure the respective components of the current. However, as shown in FIG. 2, one component is switched by the switching controller 12 and the switching device 10 alternately and the DC value is retained by the level retaining device 11. It is possible to That is, the input and output of the AC / DC converter 7 are simultaneously switched by the switch under the control of the switching controller 12, and the voltage and the current are alternately selected. When the voltage is selected, the voltage component is converted from AC to DC, and the DC value is held in the voltage level holding circuit 11. When a current is selected, the current component is converted from an alternating current to a direct current, and the direct current value is held in the current level holding circuit 11.

効果を生ずる。The train detection of the track circuit is determined so that the short-circuit resistance value can be reliably detected at 0.06Ω or less. Therefore, the track circuit that sets the short circuit display short-circuit display setting value to 0.06Ω is shorter than the train detection of the current comparison method based on the fact that the ratio of the track circuit current using the track circuit current is equal to or more than a certain value. The train detection by the apparatus according to the present invention can be directly confirmed. Furthermore, in the case of the device according to the present invention, the components of the device can be reduced in size, so that the device can be reduced in size and weight, and the effects of improving reliability, reducing battery consumption, and the like can be obtained.
