Description

Technical Field

[0001] The utility model relates to the technical field of power transmission equipment, in particular to a power transmission equipment. Background Art

[0002] Transformers are basic equipment in power transmission and distribution systems and are widely used in industries, agriculture, transportation, urban communities and other fields. Its main function is to transform voltage to facilitate long-distance transmission and distribution of electric energy. In power systems, transformers are used to convert high-voltage electric energy into low-voltage electric energy, or convert low-voltage electric energy into high-voltage electric energy, so as to meet the voltage requirements of different purposes. Transformers play a vital role in power systems. They are not only used to increase and decrease voltages, but also to isolate and filter power signals to protect the safe operation of load equipment. At present, in order to make the installation of transformers stable, they are mostly installed with multiple bolts, which has low installation efficiency. In addition, the bottom of the transformer is too close to the ground during installation, resulting in external water vapor or moisture eroding and damaging its bottom when there is too much rain, which reduces the service life of the transformer. Therefore, we have launched a new transmission equipment. Utility Model Content
