Plate, two supporting elements being separately positioned between upper clamp plate and two current ferric cores, the branch being connected between two potential windings
Strut is respectively arranged with a support plate, the potential winding between two potential windings and two current coils
Component, current coil component, support component is integral by poured with epoxy resin and constitutes the epoxy resin poured body.
The beneficial effect of above structure is：The combination transformer simple, stable and reliable for performance, good insulation preformance with structure
The advantages of, support plate can fix the pouring position of current coil, potential winding, ensure that between current coil and potential winding
Insulation spacing, and in casting epoxy resin, poured with epoxy resin material can be completely into in current coil, potential winding
Portion avoids cracking caused by epoxy resin layer thickness unevenness to ensure that the thickness of the epoxy resin layer of casting is uniform, from
And the yield rate of the manufacture of the combination transformer is improved, the dielectric strength of epoxy resin poured body is also improved, thus the group
The partial discharge quantity for closing mutual inductor can be up to state standards, and greatly prolong the service life of entire combination transformer.
Particularly, one end of the supporting element is fixed on upper clamp plate, and one end of supporting element has arc-shaped sheet
