Integrated transformer and test method

Abstract

The invention belongs to the technical field of transformers, and particularly relates to an integrated transformer and a testing method, and the integrated transformer comprises a transformer body and a transportation protection structure; the transformer body is mounted in the transportation protection structure through bolts; the transportation protection structure comprises a base and a rotating cover; rotating covers are rotationally mounted on the two sides of the top of the base, a plurality of fixing grooves are formed in the outer side of the bottom of the base, the rotating covers on the two sides are fixedly connected through bolts, and a transformer body is bolted to the middle of the base; the base is installed in a vehicle hopper of a transport vehicle through bolts, the transformer body is hoisted to the base, the rotating covers are fixed and locked through the bolts, the rotating covers on the two sides are connected and fixed through the bolts, the transformer body is shielded and wrapped, and therefore gravel and dust on the top face of the transformer body are reduced; and therefore, the cleanliness of the transformer body during installation is improved, and the installation convenience and the operation stability of the transformer body after installation are reduced.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to an integrated transformer and a testing method. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage, mainly composed of the primary coil. Composed of secondary coils and iron cores, transformers are the basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. [0003] A Chinese patent with publication number CN111508693A discloses an integrated transformer including a first inductor and a second inductor. The first inductor includes a first winding and a second winding, wherein the first winding has a first outer ring, and the second winding has a second outer ring. The second inductor includes a third winding and a fourth winding, wherein the third winding has a third outer ring, and the fourt...

AI Technical Summary

Problems solved by technology

[0004] With the development of science and technology society, electricity in various remote areas is gradually popularized, and transformers are also installed and used in various areas; in deserts and loess plateaus, sand, stone and dust have brought great impact on the installation and transportation of transformers. difficulties, especially for used transformers. When no damage occurs, it is only necessary to transfer the transformer to a new point of use and use it again. The surface of the used transformer is covered with a lot of sand and dust, and the transportation During the process, sand, stones and dust accumulate on the top surface of the transformer, which greatly brings difficulties to the installation. The sand, stones and dust need to be cleaned up. The sand, stones and dust covering the surface of the transformer can easily enter the interior of the transformer during installation.
