Transformer, mainly used to change the voltage. Without it, the electricity of the power plant cannot be used for civilian purposes.
How far are ordinary people from the transformer to be safe? Don't worry.
Let's first look at the classification of transformers. Ordinary people often see distribution transformers below 10-35 kV, generally 10 kV or 0.4 kV. According to the insulation form, they can be divided into oil immersed transformer and gas transformer. If the internal coil structure cannot be seen from the outside, it is generally an oil immersed transformer. The internal coil structure can be seen from the outside, which is generally dry-type transformer. The transformer has low noise and is mainly arranged in the power distribution room of the urban community. However, many outgoing lines are exposed. Non professionals should not enter the power distribution room. Gas transformer has high safety factor and high cost. At present, it basically depends on imports and is only used for important users, which is generally uncommon.
Then, the key question is: how far is it from the transformer to be safe? Safety factors are considered in the design of all transformers. Ordinary people can ensure safety as long as they do not touch the transformer or enter the room where the transformer is placed.
