Abstract

The invention relates to the technical field of transformers, and discloses a flexible direct current converter transformer which comprises a box body and a transformer body arranged in the box body, the transformer body is sleeved with a plurality of coil windings, and outgoing lines of the windings are led out from the side face of a long axis of the box body and on the same side. The novel flexible direct current converter transformer winding wire outlet structure is suitable for current all-indoor converter transformer space arrangement, wire inlet of all sides of the transformer is facilitated, the cost of a wall bushing is saved, later maintenance is facilitated, and meanwhile the stability of the wire outlet structure can be guaranteed through the arranged supporting assembly.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a flexible DC converter transformer. Background technique [0002] The high-voltage, high-capacity flexible DC converter station is an important "transit station" for power transmission, and the flexible DC converter transformer is the core equipment of the flexible DC converter station. [0003] The flexible DC transformers used in the existing flexible DC projects mostly adopt the oil-immersed single-phase double-winding on-load voltage regulation structure, and the winding outlet structure mainly adopts the oil-gas bushing outlet on the top of the transformer tank or the vertical oil-gas bushing outlet on the side of the short axis of the transformer. However, since the converter transformer is affected by DC bias and high-order harmonic current, it is easy to cause vibration and noise. Most of the converter transformers are installed in the whole house. Therefore, the st...
