Abstract
A kind of novel solid rolled iron core dry-type transformer of the present utility model, comprise three coils in vertical, three coil arrangements triangular in shape, also comprise the upper clamping piece and lower clamping piece that are arranged on three coil upper and lowers, described upper clamping piece and lower clamping piece are by briquetting coil pressing, the upper surface of described each coil is provided with three briquettings, and lower surface arranges three or four briquettings.The utility model is by reducing the briquetting quantity in coil upper end face, and the area that briquetting is covered on coil heat dissipation channel reduces, and then effectively strengthens the heat-sinking capability of transformer.
Description
Technical field
The utility model relates to a kind of novel solid rolled iron core dry-type transformer.
Background technology
Three-dimensional wound core dry type transformer, because of the three-phase magnetic circuit full symmetric of its iron core, has that magnetic resistance is little, exciting current and a low feature of no-load loss, and therefore economic benefit is very significantly widely used.The briquetting arrangement of three-dimensional wound core dry type transformer common is at present that coil respectively arranges 4 up and down, is uniformly distributed respectively by 360 °.Meeting cover part, the position coil airway that briquetting is arranged, affects transformer heat radiation.In addition, the increase of briquetting quantity also can increase transformer cost.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide the novel solid rolled iron core dry-type transformer with excellent heat dispersion performance.
The utility model is the first technical scheme solving the employing of its technical problem:
Novel solid rolled iron core dry-type transformer, comprise three coils in vertical, three coil arrangements triangular in shape, also comprise the upper clamping piece and lower clamping piece that are arranged on three coil upper and lowers, described upper clamping piece and lower clamping piece are by briquetting coil pressing, and the upper surface of described each coil and lower surface are respectively provided with three briquettings.
Further, three briquettings of single coil upper surface are arranged in the half-circle area non-adjacent with two other coil.
Further again, between adjacent two briquettings in described coil upper end face, angle is 90 °.
Further, three briquettings of single coil lower surface are arranged in the half-circle area non-adjacent with two other coil.
Further again, between adjacent two briquettings in described coil lower surface, angle is 90 °.
The utility model is the second technical scheme solving the employing of its technical problem:
Novel solid rolled iron core dry-type transformer, comprise three coils in vertical, three coil arrangements triangular in shape, the upper surface of described each coil is provided with three briquettings, and lower surface is provided with four equally distributed briquettings.
Further, three briquettings of single coil upper surface are arranged in the half-circle area non-adjacent with two other coil.
Further again, between adjacent two briquettings in described coil upper end face, angle is 90 °.
The beneficial effects of the utility model are: the novel solid rolled iron core dry-type transformer that the utility model adopts, by reducing the briquetting quantity in coil upper end face, the area that briquetting is covered on coil heat dissipation channel reduces, and then effectively strengthens the heat-sinking capability of transformer.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is the structural representation of embodiment one;
Fig. 2 is the structural representation of embodiment two.
Embodiment
embodiment one
With reference to Fig. 1, a kind of novel solid rolled iron core dry-type transformer of the present utility model, comprise three coils 1 in vertical, three coil 1 arrangements triangular in shape, also comprise the upper clamping piece (scheming not shown) and lower clamping piece (scheming not shown) that are arranged on three coil 1 upper and lowers, described upper clamping piece and lower clamping piece are by briquetting coil pressing 1, and described upper clamping piece is connected with briquetting 2 by nail pressing with lower clamping piece.In the present embodiment, upper surface and the lower surface of described each coil 1 are respectively provided with three briquettings 2.
In addition, coil 1 due to three dimensional wound core triangle interior dispels the heat not as the coil 1 at three dimensional wound core triangular exterior, therefore preferably, three briquettings 2 that the upper and lower end face of described single coil 1 is respectively arranged are arranged in the half-circle area non-adjacent with two other coil 1, and between adjacent two briquettings 2, angle is 90 °.
embodiment two
With reference to Fig. 2, the second execution mode of the present utility model, set by the lower surface that the difference of the present embodiment and embodiment one is described each coil 1 is four equally distributed briquettings 2.
Above-mentioned two kinds of execution modes are all briquetting 2 quantity by reducing coil 1 upper surface, and the area that briquetting 2 is covered on coil 1 heat dissipation channel reduces, and then reaches the effect of the heat-sinking capability strengthening transformer.
The above, just preferred embodiment of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
