A transformer with dry constant voltage function

Abstract

The invention discloses a transformer with drying and constant voltage function, which comprises a transformer body, the top of the transformer body is provided with a waterproof mechanism, the iron core coil of the transformer body is provided with a constant voltage mechanism, There are two tightening mechanisms under the core coil. The constant pressure mechanism includes a lower plate and an upper pressure plate. Both the lower plate and the upper pressure plate are made of insulating materials. Both ends of the lower plate are fixedly connected with fixed blocks. The ends of the fixing block are respectively fixed to the inner walls of both sides of the transformer body by bolts, the lower plate and the upper platen are respectively located below and above the coil of the transformer body, and the lower plate and the upper platen are sleeved on the iron core of the transformer body. The invention is a transformer with drying and constant voltage function. The inside of the transformer has a coil compression function, which can assist the transformer in constant voltage, and the outside of the transformer is equipped with an indicating function, which can assist workers to check whether the coil is loose and expanded during maintenance.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer with a dry constant voltage function. 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. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, etc. Transformers can be divided into distribution transformers, power transformers, etc. according to their uses. [0003] At present, most of the existing power transformers have the following deficiencies in the process of use: the coils inside the transformer will loosen during long-term use, and after the coils become loose, in the subsequent transformation process , there will be greater magnetic flux leakage, which will increase the loss of the transformer, and the existing transformer does not have a waterproof drying device,...

Problems solved by technology

[0003] At present, most of the existing power transformers have the following deficiencies in the process of use: the coils inside the transformer will loosen during long-term use, and after the coils become loose, in the subsequent transformation process , there will be greater magnetic flux leakage, which will increase the loss of the transformer, and the existing transformer does not have a waterproof drying device, the transformer is exposed to the outside for a long time, and long-term rain erosion will affect the service life of the transformer. Therefore, it is urgent to design a A transformer with dry constant voltage function to solve the above problems
