Description

The alleged invention relates to railway automation and telemechanics, in particular, to devices for detecting wheelsets on rails of the turnout itself and its branches, to automatically enter the turnout command in the woolly direction of the Movement of the train and to exclude the switch of the train under the train.

The purpose of the invention is to increase reliability.

The drawing shows a diagram of the proposed device.

The device contains a switch insulated section of the SIS of a branched section of the track, to the rails 1 of the unbranched part of which is connected a supply transformer 3 with a primary 3.1 and a secondary 3.2 windings; phase shifting element 4 connected to the rails 5 of the converted turnout curves; connected to the rails 7 of one branch and to the rails 8 of the other branch, the third windings 9.3 and 10.3 of the relay transformers 9 and 10, the first windings 9.1 and 10.1 of which are connected. on the other hand and connected to the first (track) windings 11.PO and 12.PO respectively of the first track relay 11 and the second track relay 12, and the second windings 9.2 and 10.2 of these transformers are connected according to vi are connected to the track winding 13.PO additional track relay 13. The poles of the PH and OH of the second power supply of the power supply are connected to the second (local) windings 11.MO, 12.MO of the path relay. The local windings of the relay 11 is configured for the phase of the transformer 10, and the relay 12 is on-phase current coming from the transformer, 9,

The positive-control relay 14 is connected via a series-connected front contact 12.1 of the second track relay, the rear contact 11.2 of the first track relay and the front contact 13.1 of the additional track relay to the poles P and M of the first power supply AND. The minus control relay 15 is connected to the poles P and M through the front contact 11.1 of the first track relay 11, the rear contact 12.-2 of the second track relay 12 and the front contact 13.1 of the additional track relay 13. To the switch trigger unit 16 through the front contacts 14 , 1 and 15.1 plus and minus control relays and front contact 13.1 of the additional track relay, the pole of the first power supply is connected.

The device operates as follows. In the absence of a moving unit on the rail circuit, the track relays 11 and 12 are de-energized, their front contacts 11.1 and 12.1

open, and an additional track relay 13 is excited, controlled by its front contact 13.1, not only the absence of a train shunt on the arrow, but also the absence of rails 1,5,7,8. With the advent of the moving unit on the rails. 8 one of the branches the transformer 10 windings are shunted, the relay 11 is energized and by its contact 11.1 closes the power circuit of the negative start relay 15, which by its contact 15.1 turns on the signal to block 16 to switch the arrow to the minus position. Similarly, when a movable unit enters the rails 7 of another branch, relays 12 and 14 are activated to turn on the signal to block 16 to switch the arrow to the plus position.

When the composition moves in the anti-wool direction, the input of the moving unit on the rail 1 leads to a bypass of the phase-shifting element 4 and transformers 9 and 10 .. At the same time, the additional track relay 13 is de-energized, its front contact 13.1 opens, and relays 11 and 12 remain without current, which reliably eliminates the possibility of false excitation of the relay 15 or 14 and the formation of a control signal to block 16, i.e., the danger of a switch of the arrow under the composition is reliably eliminated.
