Continuous transformer

Abstract

The invention provides a continuous transformer, comprising an iron core, output terminals, an output winding, an outer shell, metal rings, a first input coil, a threading terminal, a second input coil, revolving drums and an input terminal, wherein the iron core is a closed loop circuit one side of which is wound with the output winding the both ends of which are connected with the output terminals, the other side of the closed loop circuit is provided with two revolving drums which can freely rotate on the iron core, one of the two revolving drums is wound with the first input coil and the other of the two revolving drums is wound with the second input coil, the two coils are wound in opposite directions and are communicated with each other by passing through the threading terminal fixed on the iron core at the center of the two revolving drums, and the external ends of the two coils are respectively connected with the metal rings which are connected with the input terminal. The continuous transformer of the invention can continuously regulate output voltage and realize any voltage output value in a certain voltage range, thereby meeting demands for different electric equipment and having good generality.

Description

Technical field [0001] The invention relates to the field of electric power, in particular to a continuous transformer capable of continuously changing the output voltage. Background technique [0002] As a commonly used power device, transformers are currently divided into two categories. One is traditional transformers, which are divided into double-coil transformers and autotransformers. Double-coil transformers are mainly composed of two coils wound on the same iron core. , the principle is that the alternating magnetic field generated by the input coil passes through the iron core to generate an induced electromotive force in the output coil. According to the law of electromagnetic induction, the ratio of input\output voltage is the turns ratio of the input\output coil, and the autotransformer There is only one coil, and its input coil is the output coil. It determines the input / output voltage ratio through the voltage distribution relationship of the input voltage in t...

Problems solved by technology

[0003] However, the above-mentioned transformers have a common problem, that is, they are less versatile, and the same transformer cannot meet various transformation requirements. Although there are currently many transformers with multiple gears, their output voltage values ​​are also very limited. With the increase of various types of electrical appliances, its limited voltage range has been difficult to adapt to many different electrical equipment. Therefore, general electrical appliances need to be equipped with special transformers (this transformer is included in power supply devices such within), which results in a large part of the waste of resources
