Description

The line of blocks of relay protection of BMRZ for the electrified railroads is intended for performance of functions of relay protection and automatic equipment on the following objects:

  • networks of traction power supply of alternating current of 27,5 and 2х25 kV;
  • networks of not traction power supply of alternating current of 6-35 kV;
  • converting vypryamitelny unit of traction power supply of a direct current.

On objects of railway roads of the Russian Federation and neighboring countries more than 3000 BMRZ devices of this series are operated. BMRZ blocks are developed taking into account the specific requirements imposed to protection of objects of traction power supply and the networks feeding them contain all necessary functions of protection and automatic equipment in the structure.

BMRZ blocks are issued in two designs:

  • with the built-in control panel (monoblock);
  • with the taken-out control panel (the panel with the block connect a cable to sockets).

Each design is issued in two modifications: with a rated voltage of food of discrete entrances of 220 V or 110 Century.

Hardware features:

  • quantity of analog entrances – to 16;
  • quantity of discrete entrances – to 46;
  • quantity of discrete exits – to 32;
  • quantity of the renominated light-emitting diodes – 16;
  • nonfreezing display;
  • low requirements to size and quality of expeditious food;
  • resistance to disappearance of expeditious food – 0,5 with;
  • USB port for control and monitoring of a condition of the block.

Functional features:

  • complex of protection of traction and not traction power supply of alternating current, protection converting vypryamitelnogo unit;
  • current protection, protection on tension, remote protection, differential protection, technological protection, special protection and so forth;
  • control of serviceability of high-voltage cameras of switches;
  • calculation of a residual resource of the switch.

Communication opportunities:

  • four communication interfaces in all executions of BMRZ: USB, RS-232, RS-485, PPS;
  • protocol of data transmission Modbus-RTU.

Registration of accidents and events:

  • digital oscillograph;
  • magazine of emergency events.

Software "Relay MT Monitor":

  • change of settings;
  • changes of purpose of the renominated entrances and exits;
  • monitoring of a condition of the block;
  • reading of magazines of accidents;
  • downloading and the analysis of oscillograms of emergency events in the FastView program.
