The application provides a high-frequency transformer functional insulating material of plasmonic orientation boron nitride and a preparation method and application thereof, and relates to the technical field of insulating materials. The functional insulating material is obtained by sequentially covering, from an inner layer to an outer layer, a thermosetting resin matrix layer, a silicon-rich transition layer, an oriented boron nitride sheet layer, a boron nitride gradient insulating layer and a densified surface layer on the surface of a metal conductor. The insulating material can realize heat diffusion enhancement, electric field distribution homogenization and space charge inhibition, and exhibits high breakdown strength, high local discharge starting voltage and good long-term insulating stability under high-frequency non-sinusoidal voltage, and is suitable for insulating reinforcement of the winding end, the outgoing line end and the core clamping piece area of a high-frequency transformer of a super-speed train, and has a good application prospect.

The utility model discloses a kind of auxiliary partition and fixing structure for transformer, it is related to transformer technical field.The utility model includes transformer body, the transformer body top is provided with phase interval board subassembly, the phase interval board subassembly includes insulating plate and insulating support frame, the phase interval board subassembly one side is provided with clamp piece, the clamp piece quantity is two, and side beam subassembly is provided between two the clamp piece.The utility model improves insulating partition effect by adopting diphenyl ether plate to replace traditional epoxy resin, reduces phase-to-phase insulation distance, saves space, is conducive to the miniaturization development of transformer, while enhancing impact resistance, prolongs the service life of transformer, the " mouth " frame of side beam subassembly and clamp piece bolt lock, constitute closed loop stress system, disperse horizontal vibration stress, restrain clamp piece end deformation, guarantee stress uniform, increase the load bearing of coil, improve transformer overall stability and reliability.
