Abstract

The invention discloses a broadband filtering compensation transformer, wherein each of three phases of the transformer adopts two layers of foil windings which are insulated from each other, the two layers of foil windings which are insulated from each other are also two polar plates of a capacitor, voltage difference is generated between the two windings through a wiring mode, and a broadband inductance and capacitance (LC) filtering absorption circuit is formed. The broadband filtering compensation transformer is reasonable in design, the broadband LC filtering absorption circuit is formed, the higher harmonic of a power grid is effectively eliminated, and the reactive power of a network is compensated.

Description

technical field [0001] The invention relates to a transformer. Background technique [0002] The existing transformers cannot effectively eliminate the high-order harmonics of the power grid, and cannot compensate the reactive power of the network, which affects the working performance. Contents of the invention [0003] The object of the present invention is to provide a wide-band filter compensation transformer with reasonable structure and good working performance. [0004] Technical solution of the present invention is: [0005] A wide-band filter compensation transformer, characterized in that: each of the three phases of the transformer adopts two layers of mutually insulated foil windings, and the two layers of mutually insulated foil windings are also two pole plates of the capacitor. A voltage difference is formed between the two windings, and a broadband LC filter absorption circuit is formed. [0006] The invention has a reasonable structure, forms an LC filt...
