Description

For performance of functions of relay protection and automatic equipment the equipment set in structure is provided in networks of 0,4 kV:

  • BMRZ-0,4VV – protection of working input;
  • BMRZ-0,4AV – protection of emergency (reserve) input;
  • BMPA-0,4 – automatic equipment of input of a reserve source (AVR) and recovery of the scheme of the normal mode of power supply (VNR).

This set of the equipment is not replaceable on industrial KTP 6 (10)/0,4 of kV, compressor stations, sections of own needs of power plants, and other objects feeding electric motors of 0,4 kV.

The main feature of a set is existence of algorithm of the distant reservation (DR) operating at refusals of protection or switches of the lines departing from tires. The principle of action of algorithm of DR is other than the principle of action of usual rastsepitel of automatic switches, and provides full reservation of protection of the departing lines regardless of type and the size of loading.

The set completely replaces with itself rastsepitel of automatic switches of working and reserve inputs, and also automatic equipment of input of the reserve power supply assembled on the basis of programmable logical controllers.

BMRZ-0,4VV and BMRZ-0,4AV 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).

Functions of a set:

  • two-level maximum current protection;
  • blocking of MTZ at start-up and self-start of the engine;
  • distant reservation of refusals of protection and switches (two steps);
  • current protection of zero sequence;
  • automatic inclusion of a reserve with recovery of the scheme of the normal mode;
  • automatic control of reserve (emergency) inputs;
  • local and remote control of switches;
  • blocking of repeated inclusions;
  • memory of emergency events;
  • registration of emergency processes;
  • self-diagnostics of BMRZ;
  • work in ACS and information systems;
  • record of oscillograms of emergency processes.
