[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to convert alternating current, voltage, and impedance. It can convert electrical energy between different systems, typically those with the same frequency but different voltage and current values. Transformers are classified by application into power transformers, distribution transformers, dry-type transformers, amorphous alloy transformers, etc. A prefabricated box-type transformer, also known as a box-type transformer or prefabricated substation, is a compact set of power distribution equipment that combines high-voltage switchgear, distribution transformers, and low-voltage distribution devices according to a specific wiring scheme within a fully enclosed steel structure box. Due to its compact structure, quick installation, and high operating efficiency, box-type transformers are widely used in the construction and renovation of modern urban power grids.

[0148] In summary, the present invention provides a box-type combined transformer. During operation, the partition adjusting cylinder 21 is manually rotated. The rotation of the partition adjusting cylinder 21 drives the first screw 22 and the linkage gear seat 23 to move along the gear seat guide seat 25, thereby causing the linkage gear seat 23 to drive the driven gear 24 to rotate. The driven gear 24 drives the partition plate 14 and the equipment fixing mechanism 4 to rotate, which facilitates the assembly of high and low voltage power distribution equipment of different specifications and also facilitates the electrical isolation between high and low voltage power distribution equipment and power distribution transformer 15.

[0149] During operation, the second screw 431 is manually rotated, which drives the lifting threaded seat 432, the lifting slide plate 433, and the equipment clamping plate 434 to move up and down. This allows the equipment clamping plate 434 to clamp and fix high and low voltage power distribution equipment of different specifications. At the same time, when the lifting slide plate 433 moves up and down, it can drive the lifting rack 435 to move up and down. The lifting rack 435 drives the swing gear 436 to rotate, which in turn drives the auxiliary swing rod 437 and the auxiliary fixing frame 438 to synchronously clamp and fix the side walls of the high and low voltage power distribution equipment.

[0150] In this embodiment of the invention, an equipment fixing mechanism 4 is provided. The equipment fixing mechanism 4 consists of an equipment support 41, an equipment limiting frame 42, and an equipment fixing part 43. The equipment fixing part 43 can fix and limit high and low voltage power distribution equipment of different specifications, thereby avoiding the phenomenon of high and low voltage power distribution equipment falling off during operation. It also overcomes the problem that the prior art cannot simultaneously fix multiple side walls of high and low voltage power distribution equipment of different specifications, thus improving the assembly efficiency and difficulty of high and low voltage power distribution equipment.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
