Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of how concavo-convex cutting joint is provided, can reduce transformer noload losses, supplementary load loss, improve operating frequency and radiating effect, make complete machine reach the transformer amorphous alloy multi-inclined-plane composite iron core of medium-high frequency of low-loss, low noise, low temperature rise.
The technical scheme of the transformer amorphous alloy multi-inclined-plane composite iron core of the utility model medium-high frequency is: comprise coil and the iron core that is installed in the coil, described iron core comprises upper core and lower core, on, cutting joint is arranged between the lower core, and fixed coil on, single-phase transformer that lower clamping piece is formed, be equipped with cushion block between coil and the upper clamping piece, between coil and lower clamping piece, be equipped with lower cushion block, the lower clamping piece bottom connects base and supporting plate, it is characterized in that locating on the described upper core to be shaped on many benchboards scalariform cutting joint of upper groove and upper protruding block combination, be shaped on many benchboards scalariform cutting joint of low groove and lower protruding block combination on the described lower core, upper groove and lower protruding block are chimeric mutually, the mutual chimeric formation flux closure of upper protruding block and low groove loop.
The transformer amorphous alloy multi-inclined-plane composite iron core of medium-high frequency of the present utility model, adopt amorphous or Nanoalloy iron core, adopt rapid quench to solidify production technology, make its physical state present the unordered noncrystal arrangement of metallic atom, be more conducive to be magnetized and degaussing, thereby reduce the no-load loss of transformer significantly; The cutting joint of described upper and lower iron core is many benchboards scalariform cutting joint of groove and projection combination, the mutual chimeric formation flux closure of projection and groove loop, reducing the eddy current area, thereby reach the purpose of the technological effect of low-loss, low noise, low temperature rise.Vertical cut is no longer adopted in the cutting of described amorphous alloy iron core, adopts the cutting profile of this programme, makes an one contact-making surface be divided into a plurality of contact-making surfaces, and locating effect improves, and reduces in the amorphous alloy stem stem magnetic field simultaneously by the local flux density of many inclined-planes seam.The iron core of the technical program adopts the natural cooling pattern, make the no-load loss and the supplementary load loss of medium-high frequency transformer all reduce to minimum, for example the cutting joint contact-making surface of projection and groove is six, its eddy current loss is reduced to about 70% of common cutting (straight cuts), supplementary load loss then reduce to 10% by original 80%, reach effectively energy-conservation.
The transformer amorphous alloy multi-inclined-plane composite iron core of medium-high frequency of the present utility model, its described upper core and lower core are that non-crystaline amorphous metal material or the coiling of Nanoalloy material form, the radiating effect, the reduction eddy current loss that improve iron core reach and magnetic hysteresis loss, the inside and outside wall of upper and lower iron core is formed by epoxy resin bonded fiber and glass tape parcel, thereby guarantees the integral insulation of iron core.Its described upper clamping piece, lower clamping piece, base and supporting plate are that the epoxy glass fabric phenolic resin material is made, good insulation preformance.
