252kV Gas Insulated Switchgear(GIS) sf6 switchgear


Main features   sf6 switchgear

1.Spring mechanism/motor mechanism are adopted to avoid oil and gas to realize simple constrution, easy
maintenance and realiable operation.
2.Enclosure is made of aluminium alloy to ensure light weight, low temperature-rise and strong anticorrosion.
3.Double sealing systems are adopted to guarantee high reliability in gas tightness and ensure minimum
annual gas leakage.
4.GIS will be delivered as a whole without dismantle to reduce site installation and maintenance works.
Two measures are taken to ensure safety of operation personnel
Rupture disc is installed on every gas compartment to avoid explosion in over-pressure state.
Activating pressure of rupture disc on circuit breaker compartment: 1± 0.06MPa
Activating pressure of rupture disc on other compartments: 0.7± 0.04MPa
Destructive pressure that enclosure can withstand for circuit breaker compartment: 2.3MPa
Destructive pressure that enclosure can withstand for other compartments: 1.6MPa
6.Good insulating ability
Insulating barrier is made on production line imported form Hubers Company, Germany. The whole
manufacturing process from mixture of fillings to molding are finished in totally sealed and homoiothermal
workshop to avoid occurance of air bubble inside insulating barrier. After being kept in heating stove
for more than 16 hours, insulating barrier will be conducted X-ray non-destructive test, mechanical test,
power frequency withstand test and partial discharge test, then it will be sealing packed and delivered to
GIS assembly workshop.
7.Good conducting ability
Aluminum alloy conductors are coated with silver up to 24μm to reduce resistance as small as possible.
8.High current carrying performance
Copper with silver coat of strong adhesiveness is applied to ensure good current carrying performance
and guarantee a long-term service.
9.View window
View windows are installed on GIS main components to observe service state inside GIS.
