Description
Technical field
The utility model relates to a kind of transformer, particularly a kind of dry-type transformer.
Background technology
In the prior art, the resin casting dry-type transformer that generally uses in the electric power project of transmitting and converting electricity, generally comprise iron core and high and low pressure winding and cushion block, wherein the high and low pressure winding is to be made through cast cured explosive in watering injection molding by pours and coil, leave axial ducts between the high and low pressure winding, with fixtures such as clamping plate, pull bars the high and low pressure winding is fixedly mounted on then and constitutes transformer on the iron core, the two ends up and down and the iron core of high and low pressure winding separate by cushion block.Its weak point is: fixture bad mechanical strength such as clamping plate, pull bar, and work is long-time, easily takes place loosening; Only by the axial ducts insulation, insulation property are relatively poor between the high and low pressure winding.
The utility model content
The purpose of this utility model provides a kind of poured with epoxy resin dry-type transformer, makes its mechanical strength height, and fixed performance is good, good insulation preformance, and volume is little.
The purpose of this utility model is achieved in that the poured with epoxy resin dry-type transformer, comprise the low pressure winding of winding on iron core, low pressure winding periphery is arranged with the high pressure winding, be provided with cushion block, lower cushion block between described low pressure winding, high pressure winding and the iron core, be respectively arranged with upper clamping piece and lower clamping piece on two horizontal beams of described iron core, on the vertical post of iron core clamping plate are installed, after described upper clamping piece, lower clamping piece and described clamping plate are fixing iron core is clamped, be provided with insulating cylinder between described low pressure winding and the high pressure winding.
The beneficial effects of the utility model are: by install horizontal upper clamping piece, lower clamping piece and longitudinally clamping plate unite the clamping iron core, make iron core and upper clamping piece, the tight secure bond of lower clamping piece, thereby strengthened integrally-built stability; By between low pressure winding and high pressure winding, insulating cylinder being set, effectively reducing the insulation distance between low pressure winding and the high pressure winding, thereby make that the diameter of high pressure winding is reduced, materials reduce, volume of transformer reduces, and product cost reduces, and the insulation property of transformer are improved.The utility model can be used under the occasion of demand than small transformers.
As further improvement of the utility model, described upward cushion block, lower cushion block are formed by fixedly connecting by resin cushion block and silicon rubber cushion block, and the upper and lower end of described insulating cylinder is connected on the silicon rubber cushion block of cushion block, lower cushion block.The intensity that the resin cushion block has can be born bigger pressure, the silicon rubber cushion block directly with high pressure winding, low pressure winding between insulating cylinder be connected, by the shock-absorbing effect that the silicon rubber cushion block is play, reduced the vibrations of transformer body, further strengthened stability.
As further improvement of the utility model, described insulating cylinder composite polyester film sleeve.The insulation property between high pressure winding and the low pressure winding have been strengthened when making the assurance heat dispersion.
