Overhead Line - SF6 Gas Insulated Auto Sectionalizer

prev

prev

ENTEC overhead line SF6 Gas Insulated Auto Sectionalizer installed at branch point in down stream.

  • This is installed at the branch point in down stream of load capacity 8,000kVA of multiple earth
  • neutral system 22.9kV-Y distribution system. When over load or fault current is detected cooperates with the protection device (CB, Recloser etc. ), minimizes the damage and prevent fault expansion by closing or opening the fault section. Operation status monitoring is easily checked by load current indicator and hot line indication device.

Characteristics

25.9kV gas insulated automatic section switch cooperates with upper stream device(CB, Recloser) to protect feeder from fault currrent. And when the fault current is more than over current [Lock current(800A), upper stream protection device removes a fault solid and sound. It is used for frequent lighting place and industrial zone line, and has the following function.

  • 1) Low pressure indication and Lock function
  • 2) Gas Release Device function
  • 3) Coefficient function
  • 4) Over Current Trip Function
  • 5) Over current Locking and Tripping function
  • 6) Inrush current restraint function
  • 7) Line current and hot line indication function
  • 8) Easy function setting(LCD menu)
  • 9) Battery over-discharge preventing function
