The invention discloses a sound insulation and noise reducing type amorphous transformer. The transformer comprises an iron core, a box body, reinforcement tubes and sound absorbing fillers, wherein the box body adopts a rectangular thin-walled metal container; the reinforcement tubes are fixedly connected with the parts between inner walls on the two sides of the bottom of the box body and the iron core along the length direction; the inner cavities of the reinforcement tubes are filled with the sound absorbing fillers; vertical sound baffles are arranged between the reinforcement tubes and the iron core; the transformer has the further improvement that a sound absorbing layer made from sound absorbing materials is laid on the outer wall of the box body. The transformer adopts a sound insulation and noise measure, and obviously reduces the operating noise.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to an amorphous transformer. Background technique [0002] Amorphous transformer is a kind of energy-saving transformer, and the noise value is an important content to evaluate the operation quality of amorphous transformer. The existing amorphous transformer generally includes an iron core, a box body, a reinforcing tube, and sound-absorbing filler, and the box body is a rectangular thin-walled metal container. The main defect of the existing amorphous transformer is: the operation noise is large. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes a sound-insulating and noise-reducing amorphous transformer capable of significantly reducing operating noise. [0004] The present invention achieves technical goals through the following technical solutions. [0005] A sound-proof and noise-reducing amorphous transformer, inc...
