Substation Switchgear - Gas Insulated Switchgear (GIS)

ENTEC substation switchgear Gas Insulated Switchgear (GIS) for high purity sf6 gas for 25.8kv gis.

  • Auto Load Transfer Switch function available : Load Transfer time = 1 Cycle
  • High purity SF6 Gas is used for 25.8kV GIS(Gas Insulated Switchgear). This switching device supplies power to the transmission line by connecting to the BANK of substation.
  • Our C-GIS is Cubicle Type and has minimized the use of SF6gas. Operation apparatus life is semi-permanent and maintenance is not necessary by applying PMA method to the operation apparatus. Protects feeder system from the fault ripple effect by safe and quick breaking of fault.

Characteristics

PMA(Permanent Magnetic Actuator) method apply

  • - Reduction of parts compared with current Spring Charge mechanism.
  • - Device structure simplification by parts reduction in operation Mechanism
  • - Reliability increase by Simple Structure => Maintenance Free
  • - Semi-permanent mechanism durability by permanent magnet use => 10000times operation, no need of maintenance

  • (※ 25.8kV GIS Operation device faulty rate during 00~08.04 : 136 of 630 -> 21%
  • Quoted from 2008.08 KEPCO '25.8kV GIS Manufacturing quality improvement Special activity Report')

Cubicle Type GIS(C-GIS)

  • - Minimization of SF6 Gas use
  • - Easy installation, replacement and extension
  • - Minimizing destruction by fault current due to independent structure

Gas Pressure monitoring device and over voltage release device application.

  • - Prevention of accident by Gas rupture
  • - Prevention of 2nd accident by over voltage (Injury or Damage)

High-bright LED apply -> Monitoring of operation and reclosing status. Increase of discernment
