Damping and de-noising method for amorphous alloy transformer

Abstract

The invention relates to a damping and de-noising method for an amorphous alloy transformer, and after the process of window close of an iron core at the bottom layer is finished according to a traditional production process of an amorphous transformer, the method comprises the following steps of: (1) preparing enough large butyronitrile oil-resistant rubber gaskets; (2) cutting the butyronitrile oil-resistant rubber gaskets according to the outer contour of an upper surface of an overlap structure of the iron core at the bottom layer; (3) smearing silicone sealant on the outer contour of the upper surface of the overlap structure of the iron core at the bottom layer; (4) taking down the cut butyronitrile oil-resistant rubber gaskets and covering on a region on the iron core at the bottom layer which is coated with the silicone sealant; and (5) smearing the silicone sealant on the upper surface of the rubber gaskets, and after the steps are finished, the production of the iron core on the upper layer is finished according to the traditional amorphous iron core assembly technology. Compared with the prior art, the method improves the running safety and reliability of the amorphous alloy transformer obviously and reduces the noise of the amorphous alloy transformer.

Description

technical field [0001] The invention relates to a transformer, in particular to a shock and noise reduction method for an amorphous alloy transformer. Background technique [0002] Due to the particularity of the material of the amorphous alloy iron core of the amorphous alloy transformer, some amorphous alloy fragments are easily produced in the amorphous iron core during the assembly and operation of the amorphous transformer. If there are too many similar metal fragments inside the transformer and flow into the coil with the heat dissipation oil of the transformer, it may cause short circuit or burnout of the amorphous transformer. In addition, the vibration generated during the operation of the amorphous transformer itself will also accelerate the formation of amorphous fragments inside the amorphous transformer. Therefore, how to better reduce the vibration of the transformer itself during operation and limit the flow of amorphous fragments to the greatest extent have ...

AI Technical Summary

Problems solved by technology

Although this traditional process has achieved the fixation between the two layers of iron cores to a certain extent, the effect in reducing the vibration and noise of the iron cores is not ideal.

Therefore, if the traditional production process is followed, with the operation of the amorphous transformer, the vibration of the iron core under the action of electromagnetic force will not only produce a large noise, but also continue to form some tiny amorphous fragments, which affects the performance of the amorphous transformer.
