Description

TECHNICAL FIELD The present disclosure relates to the technical field of transformers, and in particular, to a transformer. BACKGROUND A transformer is an apparatus that changes AC voltages based on the principle of electromagnetic induction, and its main components are a primary coil, a secondary coil and an iron core (magnetic core). Clamps are disposed on the upper and lower parts of the iron core of a traditional transformer, and the clamps are mainly configured to fix and support the entire iron core and coil. Traditional clamps are generally made of carbon steel. Due to the conductivity of the carbon steel, when the transformer is over-voltage or struck by lightning, the charged bodies, such as coil or lead wire, may discharge to the clamps, which may cause transformer failures in serious cases. At the same time, although the clamps can clamp the iron core and compress the coil, the clamps also block part of the heat dissipation areas of the iron core and the coil, thus having a certain influence on the heat dissipation of main heating elements such as the transformer core and coil. Further, the traditional clamps require pickling, phosphating and painting during the production process, which is harmful to the environment. In addition, the clamp has a long production, labor-intensive, low efficiency and high cost process, which affects the production of the transformer. SUMMARY For this reason, it is necessary to provide a transformer to address the defects problems in the structure and production process of traditional transformer clamps. A clamping assembly used in the transformer can avoid blocking heat dissipation areas of an iron core and a coil, and the production process of the clamping assembly is harmless to the environment, and can effectively shorten the production process and reduce the labor intensity. According to one aspect of the present disclosure, a transformer is provided, which includes: a base;a clamping assembly mounted on one side of the base, where a clamping gap is formed on the clamping assembly in a vertical direction; anda transformer body supported on the clamping assembly and clamped in the clamping gap. In one embodiment, the clamping assembly includes a first clamping unit including a first tightening screw, an upper pressing plate and a lower pressing plate. The first tightening screw is mounted on the base at one end of the first tightening screw. The upper pressing plate and the lower pressing plate are sleeved on the first tightening screw at intervals, so that a first clamping gap configured to clamp and support the transformer body is formed between one side, facing the lower pressing plate, of the upper pressing plate and one side, facing the upper pressing plate, of the lower pressing plate, and the first clamping gap being used. In one embodiment, the clamping assembly further includes a plurality of second clamping units which are arranged at intervals along a circumferential direction and around an outer edge of the transformer body. In one embodiment, each of the plurality of second clamping units includes a second tightening screw, an upper pressing block and a lower pressing block. The second tightening screw being mounted on the base at one end of the second tightening screw. The upper pressing block and the lower pressing block are sleeved on the second tightening screw at intervals, so that a second clamping gap configured to clamp and support the transformer body is formed between one side, facing the lower pressing block, of the upper pressing block and one side, facing the upper pressing block, of the lower pressing block. In one embodiment, the transformer body includes: an iron core arranged on the base; anda coil sleeved on a core column of the iron core, where the coil includes a primary coil and a secondary coil, where the primary coil is coated outside the secondary coil in a circumferential direction. In one embodiment, the transformer further includes a primary lead which electrically connects to an outgoing line of the primary coil, and has a primary terminal, and a secondary lead which electrically connects to an outgoing line of the secondary coil, and has a secondary terminal. Both the primary terminal and the secondary terminal are used for grid connection. In one embodiment, the base includes a bottom plate and two support beams separated from each other. The bottom plate spans across the two support beams. The transformer body and the clamping assembly are mounted on one side of the bottom plate opposite the support beams. In one embodiment, the transformer further includes an upper bracket including an upper bracket body disposed on the clamping assembly, and an iron core pressing plate mounted on the upper bracket body to compress the iron core. In one embodiment, the transformer further includes a plurality of insulating struts which are arranged at intervals along a circumferential direction and around the transformer body. Accordi
