Abstract

The invention provides a dry-type transformer with heat radiation and noise reduction functions. The dry-type transformer comprises clamps and a base. Iron cores are fixed to the clamps respectively,and are fixedly limited by the clamps. A high-and-low-voltage winding coil is wound around each iron core. The iron cores are arranged on the base. A plurality of fans are arranged at positions, on two sides of the iron cores, of the base, and are mounted in a detachable mode. The dry-type transformer is characterized in that each clamp comprises a group of elongated steel plates and fixing screws; a fixing hole is formed at each of two ends of each elongated steel plate; the fixing screws penetrate the fixing holes to fasten the clamps through screws and nuts; each group of the elongated steel plates includes two elongated steel plates same in structure; an elastically-compressible or elastically-expansible separation layer is arranged on one side surface of each elongated steel plate; the thickness of each separation layer is 4-5cm when the corresponding separation layer is not compressed or expanded.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a heat-dissipating and noise-reducing dry-type transformer. Background technique [0002] With the rapid economic growth, all kinds of electrical equipment are continuously developed and applied to various occasions. Among them, dry-type transformers have become an essential key equipment and are widely used in many occasions, such as airports, hospitals or shopping malls that require a large amount of power supply. However, the existing dry-type transformers often generate noise due to their own structural factors during normal operation, which affects the environment. A traditional dry-type transformer includes a transformer core, a clamp and a base for supporting the transformer core and the clamp. The clamp includes a high-voltage upper clamp, a high-voltage lower clamp, a low-voltage upper clamp, and a low-voltage lower clamp. The transformer iron core is fix...
