Detailed Description
The invention is further described with reference to the following specific drawings and examples.
As shown in fig. 1 and 2: in order to conveniently realize the wire inlet wiring of the high-voltage side of the dry-type transformer, reduce the volume of a transformer shell, save the production cost and improve the operation safety, the utility model discloses a main cabinet 1 for accommodating the side wire inlet dry-type transformer and an auxiliary cabinet 2 arranged at the upper part of one end of the main cabinet 1, the auxiliary cabinet 2 comprises an auxiliary cabinet bottom plate 4 and an openable and closable auxiliary cabinet door 3, a bottom plate high-voltage cable hole 9 is arranged on the auxiliary cabinet bottom plate 4, and the bottom plate high-voltage cable hole 9 is communicated with the auxiliary cabinet bottom plate 4; the main cabinet end plate 5 corresponding to the auxiliary cabinet 2 is provided with a wall bushing hole 11 adapted to the wall bushing 6 and an insulator hole 12 adapted to the insulator 8, the wall bushing 6 is mounted on the main cabinet end plate 5, and the wall bushing 6 is communicated with the wall bushing hole 11.
Specifically, the main cabinet 1 can accommodate the side-inlet dry-type transformer, and the side-inlet dry-type transformer can be protected after being placed in the main cabinet 1. In the side-in dry-type transformer, cables are led in from the same end of the dry-type transformer. In order to meet the incoming line wiring of the side incoming line type dry-type transformer, the auxiliary cabinet 2 is arranged on the upper portion of one end of the main cabinet 1, the size of the auxiliary cabinet 2 is far smaller than that of the main cabinet 1, and the incoming line wiring of the dry-type transformer can be protected through the auxiliary cabinet 2.
