Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3 An automatic installation device for a transformer in a substation includes a housing 1, a mounting groove 11 is provided on the front side of the housing 1, the mounting groove 11 is a groove structure with both the front side and the lower side being connected, a sealing door 2 is installed on the front side of the housing 1, and a handle 3 is installed on the sealing door 2;

[0020] Among them, it also includes a placement mechanism, which includes a bottom plate 7, which is located at the bottom part of the installation groove 11 and is slidably connected to the inner wall of the installation groove 11. Two positioning grooves 10 are symmetrically opened at the upper end of the bottom plate 7. The two positioning grooves 10 correspond to the two U-shaped steels at the lower end of the transformer (the two U-shaped steels are symmetrically installed at the lower end of the transformer, which is the prior art). When the U-shaped steel is placed in the positioning groove 10, the front, back, left and right sides of the U-shaped steel are in contact with the front, back, left and right sides of the positioning groove 10 respectively, and half of it is located in the positioning groove 10, and the other half is located above the bottom plate 7, just corresponding to the subsequent clamping plate 6;
