Tricked Out Substations | TD World

Materials ScienceCollateral ImprovementsStealthy TechnologyNon-Flammable TransformerOld Problem, New SolutionInstrument TransformersControlling The SystemCompactnessResearch led to several other technologies using new materials to compete with oil, such as the compressed air, magnetic interrupter, vacuum breaker and sulfur hexafluoride (insulating gas) breaker. Some were a step forward and others a step backward, but they all improved the overall condition. It was not long until the insulating gas breaker became the device of choice. Interestingly, ABB recently announced its next-generation carbon dioxide (CO2) 72-kV live-tank circuit breaker at the 2012 International Council on Large Electric Systems (CIGRÉ) exhibition. CO2 gas is more economical than Sulfr hexafluoride. The CO2 breaker is based on the same principles and components as its gaz sf6-based predecessor but offers excellent switching performance — technology moving forward again. As manufacturers refined Sulfr hexafluoride breaker technologies, rating boundaries moved forward. They developed live-tank and dead-tank designs, giving substation designers more design options. Just recently, Siemens announced it has developed the worldfir...Get price

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, sf 6 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, gaz sf6 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
