Description

The utility model relates to electrical engineering, in particular, to the distribution of electrical energy, and can find application in the power supply circuits of signaling, centralization and blocking devices used in railway transport.

A known power supply system for signaling, centralization and railroad lock devices, comprising an AC power source to which an alarm, centralization and interlocking line is connected, which is the main power line, and a longitudinal power line, which is a backup power line, at least one signal point , which is a consumer of electric energy, connected to the main and backup power lines [L.1].

The power supply system of signaling devices, centralization and blocking of railways described in [L.1] is characterized by relatively low operational reliability, since in the absence of power supply to the signal point, which is a consumer of electric energy, caused by a power failure of the lines, blackouts of the lines due to repair work, disconnecting alarm, centralization, blocking lines for powering railway crossings, etc.

The utility model solves the problem of creating a power supply system for alarm, centralization, blocking devices, characterized by high operational reliability due to the presence of

autonomous power supply of a signal point in a number of situations due to a power failure, blackout of lines in connection with repair work, disconnection of an alarm line, centralization, blocking to power railway crossings, etc.

To solve this problem, the power supply system of signaling, centralization, railroad lock devices, containing an AC power source, to which the signaling, centralization, interlocking line is connected, which is the main power line, and the longitudinal power line, which is the backup power line; at least one signal point, which is a consumer of electric energy, connected to the main and backup power lines, it is proposed to additionally introduce a device for powering the signal point, connected between the signal point and the DC contact network, designed to power the electric rolling stock.

The utility model is illustrated by the example of the drawing, which schematically depicts the inventive power supply system for alarm, centralization, blocking of railways.

The power supply system of signaling, centralization, blocking of railways contains a power source of 1 AC voltage of 6 ÷ 10 kV. The signaling, centralization, blocking line, which is the main power line 2, and the longitudinal power supply line, which is the backup power line 3, are connected to the AC power source 1.

Signal point 4 is connected to the main 2 and backup 3 power lines.

The power supply system contains an additionally introduced device 5 for powering the signal point 4 connected to the signal

point 4 and to the contact network 6, designed to power the electric rolling stock 7.

Contact network 6 for powering the electric rolling stock 7 is connected to a power supply 8 of direct current voltage of 3 kV.

The presence in the device 5 for powering the signal point 4 of the unit, which converts direct voltage to alternating voltage, will allow in the absence of voltage in one of the power lines: the main 2 or backup 3 or in both of these lines to supply voltage from the contact network to supply the rolling stock to the signal point that is a consumer of electrical energy.

Performing redundancy of the power lines of signaling, centralization, and blocking devices in railway transport in this way will increase the operational reliability of the power system of these devices by eliminating the blackout of power consumers when there is no power in one of the lines: main or backup or in both of these lines, thereby reducing downtime electric rolling stock.

In accordance with the claimed decision, technical documentation has been developed that implements the claimed solution, which is supposed to be used on one of the railways of the Russian Federation.
