DVCAS

DVCAS switchgears functional groups have been designed as compact units, and built as the union of modular switchgears.

Each of the modular functions is composed of:

• Metal base frame
• Operating mechanism and relay compartment
• MV cable compartment
• Stainless steel, gas-tight cubicle which uses SF6 gas as insulating medium and houses the busbar system and the breaking devices.

General electrical/Constructive data:

• Frequency Hz 50
• Rated voltage kV 36
• Insulation level
  >Power frequency withstand voltage kV 70
  >Lightning impulse withstand voltage kV peak 170
• Rated current of the main busbar A 630
• Short time withstand current kA/s 20/3
• Short circuit breaking current capacity kA 20
• Short circuit making capacity kA peak 50
• Internal arc withstand IAC AFL kA/1s 20
• Degree of protection
  >HV compartment IP 67
  >LV and operating mechanism compartment IP 3X
• SF6 gas pressure at 20ºC bar 0.3
