detailed description

In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the present invention is an angle steel tower type distribution transformer, which includes a tower type support 1, a switch cabinet 2 and a transformer 3.

The tower bracket 1 includes four supporting legs 11 and stiffeners 12 connecting and fixing the four supporting legs 11, the stiffening ribs 12 and the four supporting legs 11 are connected and fixed by auxiliary connectors 4, four Rib plates are arranged between the two supporting legs to enhance the stability of the supporting legs.

The bottoms of the four supporting legs 11 are respectively provided with tower bottom foot plates 5 , and the tower bottom foot plates can be welded to the support legs by welding or connected to the support legs by bolts.

The upper part of the four supporting legs 11 is provided with a square frame 13, and the square frame 13 is fixed on the four supporting legs 11 through bolt connection. On the one hand, the square frame can enhance the stability of the four supporting legs when standing, on the other hand, it is convenient to install the transformer fixing base, and enhance the stability of the transformer after installation.

The switch cabinet 2 is arranged inside the tower bracket 1, and is fixed on the switch cabinet placement plate 6 provided inside the tower bracket 1, and the switch cabinet 2 and the switch cabinet placement board 6 are connected by bolts, so that That is, it is convenient to carry and install.

The switch cabinet placement plate 6 and the four supporting legs 11 of the tower bracket 1 are also fixed by bolts, which is also convenient for handling and assembly.

The transformer 3 is arranged on the upper part of the tower support 1 , and a transformer fixing base 7 is provided between the tower support 1 and the transformer 3 for connecting and fixing the transformer 3 and the tower support 1 . During installation, first install the transformer on the transformer fixing base, and then install and fix the transformer fixing base on the square frame on the upper part of the four supporting legs through bolts.
