Utility model content

For drawbacks described above present in prior art and deficiency, the utility model provides a kind of single-phase intelligent voltage stabilizing and become Depressor.

The utility model is achieved by the following technical solution：A kind of single-phase intelligent voltage stabilized transformer, global design For single-phase six pole structure, it is characterised in that：The structure of transformer needs two other magnetic circuit iron cores, a main magnetic circuit iron cores and four Individual laterally other magnetic circuit iron yoke is formed, and magnetic circuit iron core is respectively arranged in main magnetic circuit iron core both sides, two other magnetic circuit iron by two of which Each horizontal other magnetic circuit iron yoke of installation two above and below core；

Main magnetic circuit iron core is that two main magnetic circuit iron core columns and upper and lower iron yoke are formed, and other magnetic circuit iron core is arranged to two, each Formed for two other magnetic circuit iron core columns and upper and lower iron yoke, global design is single-phase six pole structure.

Preferably, distinguish coiling transformer dc excitation wire in the other magnetic circuit iron core column of four of the transformer both sides Circle.

Preferably, coiling secondary transformer is distinguished in described two main magnetic circuit iron core columns of transformer.

Preferably, described two primary coils of transformer are wound on outermost, two sides are surrounded inside each primary coil Magnetic circuit iron core column and two transformer dc magnet exciting coils being enclosed in two other magnetic circuit iron core columns and a main magnetic circuit iron core column An and secondary transformer being enclosed in main magnetic circuit iron core column.

It is further described that the other magnetic circuit iron core column of transformer dc magnet exciting coil and middle coiling in two coilings of both sides The main magnetic circuit iron core column of secondary transformer, is surrounded by primary transformer coil around being made as one group, totally two groups；This transformer Structure in be provided with four transformer dc magnet exciting coils, two primary transformer coils, two transformer secondary lines altogether Circle.

Using three, this single-phase intelligent voltage stabilized transformer can form a three-phase transformer.

Utility model works principle：

DC current is passed through in two direct-flow magnet exciting coils of single-phase transformer, so as to adjust magnetic circuit by transformer The magnetic saturation of iron core, after other magnetic circuit iron core magnetic saturation raises, the flux component of the alternating current in other magnetic circuit iron core will Reduce, the magnetic flux of reduction is squeezed into main magnetic circuit iron core, the voltage rise for exporting transformer secondary.When other magnetic circuit iron core magnetic is satisfied After being reduced with degree, the flux component of the alternating current in other magnetic circuit iron core will increase, and the alternating magnetic flux in main magnetic circuit iron core will Reduce, reduce the voltage that transformer secondary exports.

The utility model beneficial effect：

（1）The transformer on-load voltage regulating of free voltage grade can be realized using this mode, and improves voltage stabilized transformer Response speed, realize the quick voltage stabilizing of transformer output.

（2）By the way of magnetic flux is adjusted, the step-less adjustment of pressure regulation is realized, and limit without voltage stabilizing access times.

（3）By adjusting the output of DC excitation electric current, the voltage harmonic in power network can be filtered out.
