Abstract

The invention discloses an autotransformer, which comprises an upper bracket and a lower bracket. The upper and the lower brackets are respectively provided with transmission plates made of plastic. The transmission plates are connected with three coil columns. Coils are arranged outside the coil columns. Iron cores are arranged inside the coils. Protective layers are arranged on the surfaces of the coils. The autotransformer can be applied to a large-scale transformer substation to effectively change voltage and current. The manufacturing work and method are convenient and the manufacturing cost of is saved. The autotransformer is internally provided with an absorbent to remove moisture inside, is good in safety performance and not easy to be shocked by electricity. Spray paint is sprayed on the coils, so that the service life is effectively prolonged. The autotransformer is a scheme with a novel design and is beneficial to popularize.

Description

technical field [0001] The invention relates to the field of electrical transmission processing and manufacturing, in particular to an autotransformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. For example, the patent application document of China Application No. 201120565868.8 discloses the technical field of railway traction power supply and transformation system, and s...
