AI Technical Summary
Existing conventional oil-immersed transformers have insufficient short-circuit withstand capability and lack dynamic reactive power and harmonic regulation functions, making it difficult to meet the dual requirements of modern complex power grids for high equipment reliability and proactive power quality management.
It adopts a mechanically reinforced structure with a fully compressed arc plate, multiple support plates, and a central rod for clamping. Combined with an adjustable inductance module, it achieves continuous and precise control of the inductance through the axial grouping and radial insertion depth adjustment mechanism of the magnetic sheets. The reset component ensures the synchronous movement of the magnetic sheets.
It improves the short-circuit withstand capability of transformers, enables continuous and precise adjustment of inductance over a wide range, has the ability to dynamically and smoothly adjust reactive power or suppress harmonics, reduces the risk of failure, and enhances the active support capability of equipment and power quality.
