Test box for fault protection SIMUlation

SFS/SIMU

Types:

SFS/SIMU
Test box for fault protection SIMUlation for circuit breakers and disconnectors for checking:
- Field interlocks
- System internal interlocks
- Transformer interlocking interlocks

Function

  • Simulation of control panels (one control panel per card)
  • Comprehensive verification of all interlocking conditions
    - Field interlocks
    - Internal interlocks
    - Transformer interlocking interlocks
  • Checking the systems without affecting the system condition

Controls and displays

  • S1 button, ON for switching error protection ON
  • S2 button OFF for switching error protection OFF
  • S3 toggle switch for malfunction, for switching error protection deactivated = both LEDs off
  • Selector switch (sliding switch) to select the control voltage (60V DC or 220V DC)
  • LED, green ON for switching error protection ON, red OFF for switching error protection OFF

Electrical characteristics

  • Control voltage 60V DC or 220V DC
  • SFS EIN/AUS (blue bushes): External control switching error protection
    (same voltage as control voltage)
  • SFS ON/OFF (yellow bushes): Output of the switching error protection state (medium voltage)
  • Signal voltage (SFS on/off (= yellow bushes)) 
    max. Switching current AC1: 250V, 7A
    max. Switching current DC1: 30 / 110 / 220V, 7 / 0,25 / 0,12A
