High-voltage lead structure for three-dimensional wound core of transformer
A high-voltage lead structure for a three-dimensional wound core of a transformer that includes a three-dimensional wound core spliced by three rectangular single frames, and A-phase, B-phase and C-phase windings. The three-dimensional wound core includes three core legs, an upper iron yoke and a lower iron yoke. The upper iron yoke and the lower iron yoke of the three-dimensional wound core are triangular structures respectively. The A-phase, B-phase and C-phase windings are correspondingly arranged in the three core legs. Each single-phase winding includes an internal low-voltage winding and an external high-voltage winding. High-voltage windings of the A-phase, the B-phase and the C-phase are jointly connected to a tap switch through lead-out wires. The tap switch is located outside the triangular structure of the upper iron yoke and is arranged in a vertical extension line of a midpoint between the A-phase and C-phase windings.
