Abstract

The invention provides a dual-control dynamic compensation transformer, which comprises a transformer shell and a transformer main body (1), and is characterized by further comprising an intelligent reactive compensation acquisition control unit (2), a PLC (Programmable Logic Controller) (3), a main protection switch (4), a plurality of dynamic compensation loops and ion radiators (9) uniformly arranged on the inner wall of the transformer shell. And the dynamic compensation loop comprises a fuse (5), a reactor group (6), a compensation capacitor (7) and a filter (8) which are connected in sequence. According to the application, the phase-controlled reactor and the PLC are added into the dynamic reactive power compensation circuit, so that the special requirements of different customers onreactive power compensation control can be better met, and the protection function and the switching function of the reactive power compensation controller are more fully applied.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a double-controlled dynamic compensation transformer. Background technique [0002] With the rapid growth of my country's economy, it is imperative to build a smart grid. The intelligent transformer adapts to the development direction of intelligent, energy-saving, efficient and reliable power supply in the field of power transformation. It can track the load change through the intelligent controller to automatically supplement the reactive component, and upload it to the power supply background synchronously to ensure high-quality, efficient and reliable power supply, greatly reducing the power consumption of the transformer. The no-load loss is about 70% to 80%. Due to the frequent start-up and the emergence of a large number of impact load equipment, the quality of the power grid is very poor. In order to ensure the normal and reliable operation of electrical equipment, ...
