The fixed structure of a kind of three dimensional wound core open dry-type transformer top briquetting, comprise three coils in vertical, three coil arrangements triangular in shape and upper end of each coil is provided with insulating end ring, the upper surface of each insulating end ring is shelved with the briquetting for coil pressing, the top of described briquetting is provided with upper clamping piece, the bottom face of this upper clamping piece is provided with the nail pressing for compressing described briquetting.
As the improvement of technique scheme, on described each coil, correspondence is provided with four briquettings, and four briquettings are uniformly distributed in the upper surface of insulating end ring and the angle between adjacent two briquettings is 90 °.
As the further improvement of technique scheme, described insulating end ring is spliced mutually by the insulation half-turn that two is semicircle shape, and described briquetting is pressed in the conjugation position place of two insulation half-turns.
Preferably, described upper clamping piece is the hexagonal-shaped frame of a hollow, the middle position of this hexagonal-shaped frame is provided with the briquetting fixed head for compressing the briquetting below it, the transverse slat of described briquetting fixed head upwards arches upward the level height making its level height higher than magnetic bobbin core upper end, and the lower surface of this transverse slat is provided with the nail pressing for compressing the briquetting below it.
Further, the length of the nail pressing described transverse slat arranged is greater than the length of the nail pressing that upper clamping piece is arranged.
The beneficial effects of the utility model are: because the utility model is by the described briquetting of compression of upper clamping piece, then briquetting coil pressing again, prevent coil from loosening, ensure that the impact resistance of coil, and do not need the briquetting being utilized tie-rod coil pressing by lower clamping piece, therefore can not increase the phase spacing between three coils, ensure that the insulation distance between coil can not increase; Each coil has been evenly arranged four briquettings in addition, the stressed of coil can be made evenly, thus can coil pressing better.
