摘要
PURPOSE: A rail damage detection apparatus and a method thereof are provided to detect damages of the existing rail without a malfunction of a track circuit device by a bypass circuit because a multi-trance which nutral point is connected to a retrace line for returning a catenary current to a overhead earth wire is used.;CONSTITUTION: A rail damage detection apparatus comprises multi trances(T1,T2) and a rail damage detecting unit. The multi trances are impedance bonds(220,222,230,232,240,242,250,252) installed by being intercrossed a first rail(20) and second rail(22) where a train moves. The multi trances connects a nutral point to a retrace line(50) for returning a catenary current to a overhead earth wire(40). A current value flowing through second winding wires of each trans-coil of the multi trances is within a predetermined range, the rail damage detecting unit decides the damage of a rail.;COPYRIGHT KIPO 2012
