Research and design of 40.5 kV intelligent and environment-friendly cubicle gas-insulated switchgears
Since SF6 gas is one of the six greenhouse gases listed by the Kyoto Protocol, an environmentally friendly cubicle gas-insulated switchgear (C-GIS) using N2 as the principal insulation medium was developed. This work investigates N2-insulated C-GIS, an environmentally suitable alternative to SF6. Test and engineering demonstrate a 140 mm minimum insulating distance between phases and three-station fractures under 0.04 MPa. The insulation fulfils 95 kV/1 min power frequency endurance and 185 kV lightning impulse withstands voltage. Auxiliary heat dissipation reduces main circuit temperature and optimises product construction to meet 2500A rated current. Intelligent components provide real-time data collection and upload, remote operation, monitoring, and main component problem diagnostics. The 40.5 kV intelligent environmental protection gas insulated metal closed switch equipment has compact volume, maintenance-free, steady insulation performance, safe and dependable operation, and is appropriate for medium voltage distribution.
