Description

MONOBLOC 1250KVA SUBSTATION WITH DYN1 SEGREGATED 600V DISTRIBUTION

Section 1

15kV main switch including:

  • 1x fixed electrically operated vacuum circuit breaker
    • 15kV, 600A, 20kA
    • Loss of voltage protection (the circuit breaker opens if it loses its control voltage)
    • Tripping of the 15kV circuit breaker, in the event of breakdown of the neutral resistance or earth leakage (SE-325)
  • 1x control transformer
    • 1x 5kV and 1x 15kV (to be changed depending on the voltage used)
    • With primary and secondary fuse protection
  • 3x LED high voltage presence indicators installed directly at the 5kV switch input
  • 3x MALT sockets on each phase (load side of the 5kV switch) and 1x on the MALT outside the cabinet
  • Kirk-key interlock between the door and the switch, to prevent opening under voltage
  • Removable protection grid, to secure the changing of fuses
  • Window (safety glass) for displaying the status of the switch contacts
  • Option of a self-reclose included (see description below)
