Description

Technical Field

[0001] The utility model relates to the technical field of reactive power compensation devices, in particular to an integrated dynamic reactive power compensation device. Background Art

[0002] Reactive compensation devices are widely used in high and low voltage complete sets (inside reactive compensation cabinets). The disadvantage of the existing dynamic reactive compensation device structure is that the controller, closing protection switch, switching switch, series reactor, and parallel power capacitor are mostly used as independent components and are independently distributed in high and low voltage complete sets. During design and production, the installation dimensions and appearance dimensions of different specifications and models are inconsistent, resulting in more installation firmware required for installation, and the installation cabinet cannot save space better. Therefore, the overall compensation capacity of a single high and low voltage complete set (inside the reactive compensation cabinet) is relatively small, which means that an integrated, standardized, space-saving, easy to maintain, and easy to install integrated dynamic reactive compensation device is needed.

[0003] Therefore, there is an urgent need for an integrated dynamic reactive power compensation device to solve the above technical problems. Utility Model Content
