Damping oil immersed transformer

The invention aims at providing a damping oil immersed transformer to overcome the defects in the prior art. The damping oil immersed transformer comprises a transformer body, wherein two communicated E-shaped iron core assemblies, magnetic induction coil assemblies and damping assemblies are arranged in the middle part in the transformer body; the two communicated E-shaped iron core assemblies are in bilateral symmetry; the magnetic induction coil assemblies are arranged at the upper parts of the E-shaped iron core assemblies; the damping assemblies are arranged at the lower parts of the E-shaped iron core assemblies; and the damping assemblies are evenly arranged on the transformer body and support ends of the E-shaped iron core assemblies. The damping oil immersed transformer has the beneficial effects that the damping assemblies are arranged at the bottoms of the E-shaped iron core assemblies, so that noise generated by vibration can be effectively reduced; meanwhile, two vacuum regions are skillfully arranged on the damping assemblies according to the principle of reducing the noise transmission intensity by vacuum isolation; and the noise generated by vibration can be effectively avoided.
