DD204667A1 - CIRCUIT ARRANGEMENT FOR THE INSERTED AUTOMATIC TRACK BLOCK, ESPECIALLY IN ELECTRICAL TRACTION - Google Patents

Abstract

The invention relates to a circuit arrangement for the single-track automatic block route, especially in electric traction, with directional connection of the Gleistransformatoren. The aim and object of the invention is to reduce the cost of materials and assembly services over the prior art. According to the invention, the object is achieved in that, both in forward and in the return of the Gleistransformatoren, which are looped by one, on the insulating rod of the entrance track relay box, supply side closing contacts of a changeover relay are that between these close contacts and the Gleistransformator the leads to the motor relay attack the first block section, in which the Oeffnerkontakte the changeover relay are. The change-over relay, which is preferably a polarized relay, is turned on in the other direction via the closing contacts of the block monitor permission in one direction and over the closing contacts of the block monitor permission.

Title of the invention

Circuit arrangement for the single-track automatic route block, in particular in electric traction.

Field of application of the invention

The invention relates to a circuit arrangement for the single-track automatic route block, in particular in electric traction, with direction-dependent connection of the Gleistransformatoren.

Characteristic of the known technical solutions

In the case of the automatic route block, the route is divided into individual block sections. Each of these block sections is secured by block signals which are switched by one or more security devices such as pulse generators, track circuits or point-type train control devices. When track circuits are used, each block section is assigned a relay and a feed transformer. In the automatic track block with single-track operation, these transformers must either fulfill the tasks of the feed or relay transformers depending on the direction of travel of the train. Switching to the relay or feed direction takes place from the block group via a separate cable, since in safety-related reasons no other circuits may be routed in this cable on the first block section. This results in a high outlay, since a single cable must be routed to each switchable power transformer »

Object of the invention

The aim of the invention is to reduce the cost of materials and to reduce the assembly services.

Explanation of the essence of the invention

The invention has for its object to provide a circuit arrangement for the single-line automatic block route, especially in electric traction, with directional connection of the Gleistransformatoren, while maintaining dsr security Blockst romkreise separate cable with reduction factor for the Gleiatransformatoren be avoided.

According to the invention, this object is achieved in that both in forward and in the return line of the Gleistransformatoren, which are looped through a, arranged on. Isolierstoß the entrance track relay box, the supply side normally open contacts of a switching relays are that between these normally open contacts and the Gleistransformator the leads to attack the motor relay of the first block section, in which the Öffnerkontakte the switching relay are. The changeover relay, which is preferably a polarized adhesive relay, is turned on in the other direction via the normally open block contactors of the block monitor, and in the other direction via the normally open contacts of the block monitor.

Embodiment 1

The invention will be explained in more detail below with reference to an embodiment

Track-type transformers GT for track sections 1 and 2 are designed to be either feed or relay transformers by the permit or direction change.

At the exit of a train from station Bf. U in the direction of station Bf. V is via the changeover contacts bUE43 and bUE44 in the block group of the station Bf. U and the changeover bUEO3 and bUE04 in the relay box R on the track of the ballast transformer GTl / 1 via cable wires the track relay BZG in the block group of the station Bf, U interconnected. The power transformer GTl / 1 works as a relay generator. In the destination station Bf. V, the master contacts GT1 / 2 and BUE42 in the block group and the changeover contacts bUEO1 and bUE02 in the relay box R on the track of the GT1 / 2 ballast are connected together with the supply lines in the block group via cable cores.

The extending train in the direction V thus travels the track against the direction of feeding and the waste of the track relay BZG when occupying the track rail in the block group of the station U is guaranteed.

If a train journey from station Bf. V to station Bf. U is to be made, the permit must be changed from Bf. U to Bf.

By changing the license, the polarized relays BUEO are switched to the relay box R on the track of both stations via the switching contacts bUE51 - 54 of the block monitor permission BUE5 of the block groups in station Bf. U and station Bf. V.

The Gleistrasformator GTl / 1 in the station Bf. U is via the switching contacts bUE4l and bUE42 the block group and the switching contacts bUEOl and bUE02 in the relay box R on the track to the feed riser.

In the station Bf ₀ V, the switching transformers bUE43 and bUE44 in the block group and the switching contacts bUEO3 and bUE04 in the relay box R on the track track make the rail transformer GTl / 2 the relay transformer
