Product Description

Indoor Gas Insulation Metal-Clad Switchgear XGNS1-40.5

General description
Switchgear XGNS1-40.5 includes a series of expandable SF6-insulated metal-clad switchgears at the voltage rating of 40.5kV. All live parts of primary high-voltage circuit are wholly enclosed in a welded cabinet of 3mm-thinckness stainless steel sheets, which gives a small volume. The switchgear is not subject to the influence of surrounding conditions so that it guarantees the safe and reliable running and zero maintenance. It can be integrated as module by using plug-in expansion busbar. Meet requirements of end users or network nodes and satisfy demands of various substations and switching stations, box-type substation, cable branch boxes and wind turbine towers. It features the compact structure, safety, reliability, long life and zero maintenance.

5. Flexible modular integration with plug-in expansion busbar.

Service conditions

1. Elevation: Not more than 5000m above the sea level.
2. Ambient temperature: Max.: +50ºC, Min.: -40ºC.
3. Relative humidity: daily average is not more than 95%, monthly average is not more that 90%.
4. No apparent pollution of corrosive or combustible gas around.
5. No regular violent vibration.
6. Note: if deviation for normal service conditions occurs, the customer should inform the manufacturer before production.

 

     All parts of primary high-voltage circuit are wholly enclosed in a welded cabinet of 3mm-thickness stainless steels. The SF6 gas at 0.04MPa is filled as arc-extinguishing and insulating medium. Monitor the pressure of gas with air gauge. The back of gas chamber is equipped with explosion-proof device. When the arc pressure is too high, the high-pressure gas in the cabinet triggers the explosion-proof device and is released behind the cabinet to protect the safety of operators.
     

     Our load switch adopts the structure of gas compression and inwards arc blowing. It has the strong arc quenching force and has no influence on the insulation between phase and to the ground. The dynamic and static contacts are arcing contacts to increase breaking times greatly.

A fuse and a load switch chamber comprise a transformer protection circuit. A high-voltage current-limiting fuse is mounted in the epoxy-cast insulated housing. After the fuse burns, it triggers the pin and causes the load switch to open.
 

      An actuation chamber is in the front of ring main unit. In each functional circuit, load switch and breaker are equipped with manually/electrically-operated energy storage spring actuator while 3-position isolating switch and earth switch is equipped with manually-operated energy storage spring actuator. On the panel is a display of switch status. An interlocking mechanism connects load switch, earth switch and door of cable chamber, and breaker, 3-position isolating switch and door of cable chamber respectively.
 

     XGNS1 is a series of small metal-clad switchgears. In a SF6 insulation chamber, it can integrate at most four modules. Provide 10 configurations for distribution network and adapt to most ring network applications. Its typical configurations include Def, CCF, CCCF, CCFF, CCC, CCCC, DeV, CCV, CCCV amd CCVV. If more than 4 modules are required in a switchgear, connect switchgears with expansion busbar to shape a  semi-modular structure or connect all modules with expansion busbar for modular configuration.
