Abstract
A transformer three-dimensional wound core low-voltage lead structure is provided comprising a three-dimensional wound core formed of three rectangular single frames, and three phase windings. The wound core comprises three core posts and an yoke, the yoke being a triangular structure. The three phase windings are arranged on the three core posts, each phase winding comprising an internal low-voltage and high-voltage winding. The head end and the tail end of each phase low-voltage winding are respectively connected to a lead-out line, and the lead-out lines are located in a triangular structure region of the yoke, and a low-voltage bushing step-up module is provided above the wound core, three low-voltage bushings are provided on the low-voltage bushing step-up module, and the three low-voltage bushings are connected to the lead-out line of the corresponding low-voltage winding.
