Abstract
The utility model discloses a compact transformer lead structure, including iron core, three-phase high-voltage coil, coil head end, coil tail end, outer lead wire, folder, three-phase high-voltage coil's B is on the contrary around having the flip-chip structure. The head ends of the A phase and the C phase of the three-phase high-voltage coil are arranged above, and the tail ends of the A phase and the C phase are arranged below; the tail end of the B-phase coil is arranged at the upper part, and the head end of the B-phase coil is arranged at the lower part. The utility model discloses the beneficial effect who obtains does: the B phase is reversely connected, so that the lead wire can be connected in a serial mode, the crossing of an outer lead wire and a tapping lead wire is avoided, and the distance between the lead wire and the wall of the oil tank is effectively shortened.
Description
Technical Field
The utility model belongs to the electrical equipment field, specificly relate to a compact transformer lead structure.
Background
The external lead wire inside the existing transformer is crossed with the interphase lead wire, so that the electric field is concentrated; in order to ensure the insulation distance, the conventional avoidance method causes the length of the lead to be increased, and the transformer is large in size. Therefore, it is necessary to design a transformer with simple structure, small volume and safety.
Disclosure of Invention
The utility model provides a compact transformer lead structure with simple structure, small volume and safe use.
The utility model adopts the technical proposal that: the utility model provides a compact transformer lead structure, includes iron core, three-phase high-voltage coil, coil head end, coil tail end, outer lead wire, folder, its characterized in that: and the reverse B phase of the three-phase high-voltage coil is wound with an inverted structure.
Furthermore, the head ends of the A phase and the C phase of the three-phase high-voltage coil are arranged above, and the tail ends of the A phase and the C phase are arranged below; the tail end of the B-phase coil is arranged at the upper part, and the head end of the B-phase coil is arranged at the lower part.
Further, the outer leads are connected in a series manner.
The utility model discloses the beneficial effect who obtains does: the B phase is reversely connected, so that the lead wire can be connected in a serial mode, the crossing of an outer lead wire and a tapping lead wire is avoided, and the distance between the lead wire and the wall of the oil tank is effectively shortened.
