RAIL BREAKAGE DETECTION DEVICE AND RAIL BREAKAGE RESULT MANAGEMENT SYSTEM
A rail breakage detection device includes a first core part provided to a first cable connecting an electrical neutral point of an impedance bond that electrically connects a first rail and a second rail to the first rail, a second core part provided to a second cable connecting the electrical neutral point of the impedance bond to the second rail, a first coil wound around the first core part to generate a first electromotive force in accordance with a current variation occurring in the first cable, a second coil connected electrically to the first coil and wound around the second core part to generate a second electromotive force in accordance with a current variation occurring in the second cable, and a CPU to determine that the first or second rail is broken based on an electromotive force that is a sum of the first and second electromotive forces.
