Transformer with adjustable turns

Abstract

The invention discloses a transformer with the adjustable number of turns. The transformer comprises a shell, an iron core, a standby spool, a lifting rotating unit and a take-up and pay-off unit, wherein the lifting speed of the standby spool and the autorotation speed of the iron core are in a preset proportion, and wound coils are spiral, consistent in tightness and adjustable in density. According to the transformer, the number of turns of the coil in the transformer can be adjusted without opening the transformer shell, and then voltage transformation operation can be completed conveniently and rapidly.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a transformer with adjustable turns. Background technique [0002] Transformer refers to a device that uses the principle of electromagnetic induction to change AC voltage, and its main components are primary coil, secondary coil and iron core. The main functions of the transformer are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, etc. In electrical equipment and wireless circuits, transformers are often used for step-down voltage, matching impedance, safety isolation, etc. [0003] The transformers are equipped with two sets of wiring modules for energization, but the number of coil turns inside the existing transformers is a fixed structure, and only a certain amount of voltage can be transformed. If the voltage needs to be adjusted, the transformer needs to be opened to replace the coils. Therefore, it is easy to be l...

Problems solved by technology

[0003] The transformers are equipped with two sets of wiring modules for energization, but the number of coil turns inside the existing transformers is a fixed structure, and only a certain amount of voltage can be transformed. If the voltage needs to be adjusted, the transformer needs to be opened to replace the coils. Therefore, it is easy to be limited by sudden factors in actual use, which leads to the insufficient ability of the transformer to adjust and transform the voltage.

[0004] Disclosed in CN110911143A is a patent called "a kind of voltage ratio adjustable transformer", which discloses structures such as a movable iron core, a spare bobbin, and a lifting unit, and its disadvantages are: 1. The pay-off speed of the bobbin cannot be freely controlled , and the ratio between the bobbin lifting speed and the winding speed cannot be adjusted, and the winding quality of the coil is unstable; 2. Only the unilateral coil can be adjusted, and the adjustable voltage ratio is small
