SHORT-CIRCUITING DEVICE FOR TRACK CIRCUIT

PURPOSE:To easily confirm thc normal short circuit by displaying the short circuit confirmation of a short-circuiting device for a track circuit. CONSTITUTION:In a short-circuiting device for a track circuit to achieve the short-circuiting between rails by a short-circuiting device 2 and a short-circuiting line 4, a voltage terminal 5 is connected to the rails in addition to the short- circuiting device to short-circuit the rails to measure the voltage between the rails and the short-circuiting current from a current sensor 6 connected to the short-circuiting line. After the values are converted to the direct current by an AC/DC converter 7, the short-circuiting resistance is calculated by a divider 9, and the normal short circuit is displayed when the value is below the prescribed value.
