Modernization of control and switchgear - 6 kW for Naberezhnye Chelny TPS

Modernization of switchgear - 6 kV s. 2pa, B and 4RA, B, includes:

  • replacement of morally and physically outdated oil circuit breakers VMPE-10 vacuum WBE-10-31,5 / 630 (1000, 1600) UHL-2;
  • replacement of relay protection and control of electromechanical relays to microprocessor hardware type SPAC 810, which provides high accuracy and consistency of performance. This can significantly improve the reliability, sensitivity and responsiveness of protection and reduce the degree of selectivity.
For the protection of transformers, motors and busbars 6 kV surge arresters OPN-6 have been installed. To protect against short circuits, followed by an open electric arc, installation of arc protection with arc fault recording unit "Arc-0" was mounted; replacement of voltage transformer ferroresonance NTMI -6 Namita - 10 - 2 UHL was carried out.
