Abstract

The invention discloses a voltage regulation device and a transformer. The voltage regulation device changes a voltage regulation coil connected in series with a coiling coil to change the number of turns of the coupling coil on the transformer to change a transformation ratio, so that one transformer can become various transformation ratios. The transformer includes a coupling coil on a primary side, a coupling coil on a secondary side, and a voltage regulation device, and the coupling coil on the primary side is coupled to the coupling coil on the secondary side, and the coupling coil of thecoupling coil on the primary side or the coupling coil on the secondary side is connected with the voltage regulation device, a switching component is used for selecting the coupling coil to be connected in series with the voltage regulation coil, or release the series connection relation of the coiling coil and the voltage regulation coil, wherein when the voltage regulation coil is connected inseries with the coupling coil, the voltage regulation coil is coupled with the coupling coil at the other side.

Description

technical field [0001] The present application relates to the technical field of power transformation equipment, in particular, to a voltage regulating device and a transformer. Background technique [0002] In the power system, since the distance between the power plant and the user is often relatively far, and the output voltage of the power plant may not meet the voltage requirements of the user, it is often necessary to use a transformer to convert the voltage to complete The transfer of electrical energy from the power plant to the consumer. [0003] During the transmission of electric energy from the power plant to the user, in order to ensure the reliable operation of the power grid, it is necessary to use transformers with different transformation ratios or impedances or capacities. However, in existing transformers, each transformer generally corresponds to a transformation ratio. In this way, multiple transformers need to be prepared in scenarios where multiple v...
