Transformer convenient for voltage regulation

Abstract

The invention discloses a transformer convenient for voltage regulation. The transformer comprises a shell, a transformer body, a moving rod and a regulating assembly, the transformer body comprises a first iron core, a second iron core, a primary coil and a secondary coil, the adjusting assembly comprises a conductive pulley, a spring, a first connecting rod, a second connecting rod and a sliding seat, the sliding seat is slidably connected with the moving rod, one end of the first connecting rod is fixedly connected to the sliding seat, and the second connecting rod is hollow to form a sliding through hole; the other end of the first connecting rod is sleeved with the sliding through hole, the first connecting rod comprises a first connecting part connected with the sliding seat through a spring and a second connecting part rotationally connected with the conductive pulley, and the wire penetrates through the first connecting rod, the second connecting rod and the sliding seat to form a fourth wiring part; according to the technical scheme, by arranging the conductive pulley and the spring, damage to the secondary coil during voltage adjustment is reduced, and tight connection between the conductive pulley and the secondary coil is achieved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer convenient for voltage regulation. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core. In the power system, we use various types of transformers to complete the transmission of electric energy from the power plant to the user. Or converted into mechanical equipment that requires different voltages. With the rapid development of power equipment, the proportion of electricity in social and economic development and people's work and life is also increasing. As the demand for electricity increases, the capacity of the transformer will also increase. With the increase in the proportion of people's daily electricity consumption, the load fluctuation of transformers is also increasing; with the development...

AI Technical Summary

Problems solved by technology

[0003] The voltage regulation of the transformer is mainly realized by adjusting the turns ratio of the primary coil and the secondary coil. As we all know, the coil is the main part of the transformer, which is called the heart of the transformer. 90% of the faults of the transformer are the faults of the coils, and the existing transformers are The number of turns of the connected primary coil or secondary coil is adjusted by sliding the conductive part on the coil to adjust the turn ratio of the primary coil and the secondary coil. However, when the conductive part slides on the coil, the coil is easily scratched and damaged. Wear and tear may also make the connection between the conductive part and the coil not tight and poor contact, etc., which cannot meet the needs of users and reduce the user experience
