The EPFASG device is intended for reception and distribution of 6 (10) kV power, frequency 50 Hz, and also protection of networks with isolated neutral and control of underground current collectors of coal mines (gas and/or dust hazardous). The device is made with intrinsically safe remote control circuits, it has an explosion-proof design and bear protection marking PB Exd[ia]ia I. The shell structure provides ingress Ip54 protection according to GOST 14254-96.

The design of the FASG is unique and has no analogs. FASGs for 6 and 10 kV do not differ in overall dimensions. All the main electronic components are located on pull out module and door of the FASG that makes it more convenient and quick to perform preventive and repair work.

It provides:

  • Mechanical and electrical locking;
  • operational local and remote control of distribution device;
  • display of operation parameters;
  • grounding the outgoing connection;
  • electrical protections* (27, 50, 59, 79, etc.);
  • possibility to connect additional protections;
  • assembly of RP with performance of ACB, LZHAR functions;
  • alarm for protection operation;
  • connection of two input and output cables;
  • transfer via RS-485 interface, Modbus protocol;
  • technical power recording;
  • password protection against unauthorized access;
  • logs of emergency events and parameter changes.

Reliability indicators:

  • Average time between failures - not less than 8000 h;
  • established resource before first major overhaul - not less than 65000 h;
  • average total service life - not less than 15 years:
  • mean recovery time - no more than 2 hours.
