Description

Technical Field

[0001] The utility model relates to the technical field of distribution transformers, in particular to a silencing device for distribution transformers. Background Art

[0002] Distribution transformer refers to a static electrical appliance in the distribution system that transforms AC voltage and current according to the law of electromagnetic induction to transmit AC power. In some areas, power transformers with voltage levels below 35 kV are called "distribution transformers", or "distribution transformers" for short. The place where "distribution transformers" are installed is the substation. In the process of using distribution transformers, distribution transformers usually generate a lot of noise, and the distribution transformers need to be silenced.

[0003] When using a silencer to silence a distribution transformer, the distribution transformer is usually placed inside a silencer cabinet and then clamped by a clamping mechanism. However, the clamping mechanism can usually only clamp the distribution transformer on both sides and cannot clamp the four sides of the distribution transformer at the same time. The clamping effect is poor, and the two unclamped sides may become loose during handling and transportation, affecting the normal use of the distribution transformer. Utility Model Content
