SU30717A1 - Device for three-digit automatic blocking at operating current - Google Patents

Description

The invention relates to a device for a three-digit auto-lock on the operating current and consists in that a separate track relay, made with a self-closure, is connected to one isolated section, besides the usual track relay, so that when the train is at the site excited by both relays, the signal enclosing this section gives a blocking path indication (red light), and when the train leaves for the next section, which is accompanied by the falling off of the core of a simple track relay at the remaining excited second relay, this signal gives a warning indication (yellow light).

In the device shown schematically in the drawing, a simple track relay / and a track relay 2 with self-closing are attached to each isolated section /, ///, of the track rails. In the position shown in the drawing, green lamps W are heated in all the light signals. When the train enters the section (both relays) and 2 of this section, they are excited and their 5 points and are attracted; At the same time, the bark of the relay 2 in pin 9 turns off the green lamp JO and, closure pin 8, together with bark 3

(18F)

Relay /, closing contact 5, includes a red lamp / 2 light signal D enclosing the specified..death. At the same time, measles 4 relay 2 closes contact 7, as a result of which the circuit of this relay self-closes. When the train leaves I section and enters the next section /// box 3 of the track relay / section / disappears, the relay 2 of this section remains excited, as a result of which the red lamp 12 turns off in the light signal P- and turns on via contacts 6 vi 8 yellow lamp //. Exit to section V, the train turns on a relay 13, connected to a short segment of an insulated rail, the measles-T4 of which at the same time opens contact / 5, which is connected to a self-jammed relay 2 sections /; the relay 2 of this section is deprived of current, as a result of which the yellow lamp // is turned off in the light signal P corresponding to this section and the green lamp 10 is turned on. The movement of even trains proceeds in a similar way.

The subject matter of the invention.

A device for three-digit automatic blocking at the operating current, characterized by the use of two connected "one isolated sections of the track turnips.

of which one is made with self-closing and the contacts of the wires are so connected with each other, so that when the train enters the section and the two relays are energized, the signal protecting this section gives a blocking path indication

(red light), and when joining the train to the next section and dropping off the core of a simple track relay, this signal gave a warning indication (yellow light).
