Control unit of the BUVV SEShch B switch

The control unit of the BUVV-SEShch-B switch is intended for control of vacuum switches with a magnetic latch of VVM-SEShch family.

BUVV-SEShch-B provides:

• shutdown and turning on of the switch;
• control of position of the switch;
• control of serviceability of chains of management;
• protection against repeated inclusions;
• automatic shutdown at food undervoltage (execution without food from current chains);
• food from current chains;
• charge from a figurative power source.

  The block provides:

  • shutdown and turning on of the switch on the teams arriving on discrete entrances "Incl." and "Otkl".
  • control of position of the switch (by means of the signals arriving on a block contact chain), and also serviceability of its chains of management, diagnostics of the switch. Giving of command for turning on of the switch is possible only at the disconnected position of the switch
  • protection against repeated turning on ("jumping") of the switch. The block blocks team of turning on of the switch if the switch was switched-off by team of shutdown and from the moment of removal of the previous team of inclusion there passed less than 2,5 pages. The block available time for operation of turning on of the switch makes no more than 8 from later previous operation of inclusion
  • blocking of team of turning on of the switch in the presence of team of shutdown. The team of shutdown of the switch has a priority over team of inclusion
  • detection of spontaneous (mechanical) shutdown (MO) of the switch, that is shutdown of the switch without giving of team of disconnection from the block. At MO the team of inclusion is blocked and the light-emitting diode of the ACCIDENT block begins to give a light signal (5 flashes in sequence). For blocking removal neobkhodi-mo to give a signal on a discrete exit of the Otkl block.
  • possibility of performance of standard cycle APV 1 "and" in accordance with GOST P 52565-2006 (O-0,3 with - VO-20 with - VO).
