Description

Impedance bond for railway track {impedance bond for railway track}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impedance bond for a railway track, and more particularly, to an impedance bond for a railway track for transmitting and receiving operation control information required for a railway and a subway train.

As is well known, it is necessary to divide a railway between a station and a train into a required length for efficient control in performing speed control, stop control, progress, and stop display control of a train. The divided part is called a normal track circuit and the impedance bond is used to distinguish the signal current and the return line of the electric wire by installing it at the boundary point between the track circuits. Or a non-occupancy signal to perform a desired control function related to the train.

An example of such an impedance bond is disclosed in Korean Patent Registration No. 10-0453858 (registered on Oct. 12, 2004, hereinafter referred to as "Patent Document 1").

The impedance bond according to the prior art is divided into a transmission impedance bond constituting a transmission side track circuit and a reception impedance bond constituting a reception side track circuit.

More specifically, when there is no train on the trajectory, the transmission signal transmitted from the control device of the history is transmitted to the rail via the transmission impedance bond, the normal signal is input to the reception impedance bond on the opposite side of the track, And the contact of the orbital relay indicates a non-occupied signal as the track relay is excited and kept in the operating state. At this time, when the train enters, the wheel conducts both sides of the rail to drop the voltage of the signal entering the reception impedance bond, so that the orbital relay falls without being excited, and the contact of the orbital relay shows the occupancy signal. With this non-occupancy and occupancy signals as source signals, the history control device performs various control of the train.

However, since the control unit including the PCB (printed circuit board) is installed directly inside the housing, the impedance bond according to the related art is enlarged in size, and even if the housing is dustproofed and waterproofed, .
