new type sf6 Distributor for transformers

Oct 23, 2020 · An SF6 circuit breaker is a type of circuit breaker in which sulphur hexafluoride gas or SF 6 gas is used as the arc quinching medium, known as an SF6 circuit breaker. SF 6 gas has excellent insulating property and it has a high electronegativity. Due to high electronegativity, it has a high affinity for absorbing free electrons.

  • Distribution Transformer : Construction, Types and Its Uses

    Distribution Transformer ConstructionTypes of Distribution TransformerUses/ApplicationsFAQsThe designing of a distribution transformer can be done similarly to small size transformers. The main parts of this transformer mainly include Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing. 1. The oil tank is used to soak the windings by placing it in. 2. A conservator is arranged above the oil tank at the outside of the transformer frame. It is connected to the main tank with the help of a metallic tube. The oil within the tank can be easily contacted & enlarge throughout loading so that the temperature of the oil can be increased & decrease. 3. Buchholz relay is used when a conservator tank is used. Because it indicates errors like loss of oil once it goes low, improper flow of oil between the tank & transformer. 4. Breather Unit includes silica gel that absorbs moisture in the oil. It changes its color from blue color to pink color it is not capable to absorb moisture in the...
