ODFPSZ-700000/750
This product is a single-phase oil-immersed autotransformer with on-load tap-changer, independently developed and designed by TBEA. It adopts neutral point variable magnetic flux tap-changer and consists of two parts: the main transformer and the tap-changer compensation transformer. After being connected and combined through external bushings, the main transformer and the tap-changer compensation transformer can be used as a complete transformer, or the main transformer can be used alone. This product is one of the key equipment in large converter stations, and its function is to connect power grids of different voltage levels. By adjusting the output voltage, it can meet the needs of the power system.
