Transformer is a ακτινοβολία source, compared with high-frequency transformer, the ακτινοβολία of power frequency transformer is not very serious. Long-term electromagnetic radiation pollution. In general, the transformer should be shielded, electromagnetic radiation and isolation. This power transformer is completely open. In fact, the impact of transformer radiation on the environment is relatively small, transformer radiation is low frequency radiation， And the frequency of radiation reaches a certain height, it will affect people’s health
