Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-3, double C in combination formula transformer iron-core structures, including iron core 1 and clamping frame 3, the clamping packet of frame 3 are set
In the outside of iron core 1, iron core 1 is altogether there are two settings, and two iron cores 1 are made of several silicon steel sheets 4, in the both ends of iron core 1
Portion offers connecting hole 2, and the inner surface wall of connecting hole 2 angularly offers ventilation slot 6, the arc end middle position of iron core 1
Place offers sliding slot 8, and the two sides arc end inner surface wall of clamping frame 3 is symmetrically arranged with sliding block 9.
The section of several silicon steel sheets 4 is in the structure of falling c-type, is the lap connected structure that overlaps between several silicon steel sheets 4, and
The shape size of several silicon steel sheets 4 is consistent, it is ensured that several silicon steel sheets 4 can splice to form two complete c-type iron
Core 1, and ensure the flatness on 1 surface of iron core, it is not in uneven phenomenon.
