Intensive type DC de-icing device topology structure

The invention discloses an intensive type DC de-icing device topology structure. The intensive type DC de-icing device topology structure comprises a constant impedance low-loss connection transformer, a de-icing branch, a DC de-icing device main controller, an operation mode transformation device, a reactive compensation and active filter branch and a transformer substation bus current and voltage signal acquiring device; the transformer substation bus current and voltage signal acquiring device is connected with a DC de-icing device main controller; the control end of a static reactive compensation and active filter part is connected with the DC de-icing device main controller; the input end of the operation mode transformation mode is connected with an C bus of a transformer substation through the constant impedance low-loss connection transformer, and while the output end of the operation mode transformation mode is respectively connected with the de-icing branch and the reactive compensation and active filter branch. The intensive type DC de-icing device topology structure can perform de-icing, reactive compensation and active filter, and is reliable to run; the de-icing and the reactive compensating capacity can be independently configured; therefore, the guidance is provided for the multifunctional topology structure of the de-icing device; the intensive type DC de-icing device topology structure can be widely applied to various transformer substations.
