Electromagnetic voltage transformer and inrush current oscillation protection system thereof

The invention provides an electromagnetic voltage transformer and an inrush current oscillation protection system thereof, and relates to the field of electromagnetic voltage transformers. The electromagnetic voltage transformer comprises a voltage transformer shell and a heat dissipation controller shell, a heat dissipation frame is fixedly installed in the voltage transformer shell and is of a U-shaped structure, a heat dissipation cavity is formed between the heat dissipation frame and the inner wall of the voltage transformer shell, heat dissipation pipes are laid in the heat dissipation cavity, the heat dissipation pipes are distributed in the heat dissipation cavity in an S-shaped structure, each heat dissipation pipe comprises a liquid inlet and a liquid outlet, and the liquid inlets and the liquid outlets both extend out of the voltage transformer shell. The end parts of the liquid inlet and the liquid outlet are fixedly connected with water pipes; a water tank for storing cooling liquid is installed
