Gas Insulated Switchgear : Working, Testing Its Applications

ComponentsAdvantagesDisadvantagesGas Insulated Switchgear ApplicationsThe Gas-insulated switchgear design can be done using different components like circuit breakers, bus bars, disconnectors or isolators, transformerslike voltage and current, earth switches, lightning arresters, and surge arrestors. When the substation is connected with gas-insulated switchgear then it is called GIMES or gas-insulated metal-enclosed substation. This kind of technology is not invented recently but it is available for the past 30 years. In gas-insulated medium-voltage switchgear, gaz sf6 gas works like an insulation material whereas the vacuum technology is mainly used for the purpose of interrupting. Even though, for both insulation and interruption, the insulating gas gas can be used in several medium voltage gas insulated switchgear systems. However, for such devices, sf 6 gas pressures are dissimilar for insulation as well as an interruption. For insulating, this gas pressure is usually kept under 2.5 bar, whereas for interrupting, it is ranged from 5 – 7 bar.Get price

For sound insulation in windows, In vehicle tyres, Is gaz sf6 a health hazard? Pure gaz sf6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is insulating gas harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of Sulfr hexafluoride used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE).
