Description

{Copper wire for short circuit used in train protection for train protection}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a short-circuiting wire used for protecting a railway by short-circuiting between rails by being in contact with the railway rail installed in parallel with each other.

In the case where two or more trains operate on the same track in a railway, a line is divided into a plurality of sections (hereinafter referred to as a "block section") to prevent an accident such as a collision or a collision, (Hereinafter referred to as a "block system") in which another train is prevented from entering the obstruction section until one passage completely passes through the one obstruction section.

In such an occlusion system, two rails at both ends of the occlusion section are electrically connected to each other to constitute a rectangular electric circuit (hereinafter referred to as a " track circuit ") and electrically insulated from the adjacent front and rear occlusion sections , A power source is connected to one side thereof, and a track relay (relay) is connected to the other side thereof to detect whether the two rails are electrically short-circuited to the axle of the train, thereby detecting whether or not there is a train in the closing section.

BACKGROUND ART [0002] Conventionally, as a security device for train operation, a train detection device for detecting whether or not a train comes in by using the above-mentioned track circuit is put to practical use. When the train or vehicle enters the train, the rail and the axle of the vehicle are short-circuited by the short-circuit between the right and left rails, and the orbital relay is operated So that it is possible to detect that the train or the vehicle is in the interval. In addition, it transmits information that activates ATC (Automatic Train Control) by inducing a signal voltage to a receiver provided at the head of the train with a magnetic field generated by a signal current flowing through the rail.

However, there may be a case where it is checked whether or not the above-mentioned train detecting device operates as stipulated when performing maintenance related to a trajectory or the like or without operating a train. There is also a case where it is necessary to stop an oncoming train because an emergency occurs on the train line. In addition, when one rail is separated for the rail replacement in the impulse track circuit section, a fault may occur in the track circuit due to the unbalanced tram current. To prevent this, short-circuit both ends of the rail at the front and rear ends of the rail replacement point The flow of the water. In this case, a mechanism is required to short-circuit the rails laid parallel to each other without depending on the wheels or axles of the train.

Fig. 1 is a perspective view schematically showing a first rail contact member of a short-circuited copper wire used for emergency protection in a conventional train, and Fig. 2 is a cross-sectional view of a conventional rail- It is a perspective view connected to a rail.
