Abstract
The utility model discloses a kind of three-dimensional wound core dry type transformer with excellent heat dispersion performance, comprise three coils in vertical, three coil arrangements triangular in shape, the upper and lower end face of each coil is provided with some briquettings for coil pressing, the briquetting in described coil upper end face is arranged in outside hub of a spool and the transformer line of centres 120 ° of circumferential areas that are angular bisector, accelerate the heat radiation of transformer fe interior portion, thus improve the heat-sinking capability of transformer whole.
Description
Technical field
The utility model relates to a kind of dry-type transformer, particularly relates to a kind of three-dimensional wound core dry type transformer with excellent heat dispersion performance.
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 °.The position arranged due to briquetting can cover coil airway, therefore affects transformer heat radiation.Wherein, be not so good as the coil at three dimensional wound core triangular exterior in the coil heat radiation of three dimensional wound core triangle interior, so the coil heat radiation of three dimensional wound core triangle interior is the heat radiation short slab of whole transformer.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of three-dimensional wound core dry type transformer with excellent heat dispersion performance.
The utility model is the technical scheme solving the employing of its technical problem:
A kind of three-dimensional wound core dry type transformer with excellent heat dispersion performance, comprise three coils in vertical, three coil arrangements triangular in shape, the upper and lower end face of each coil is provided with some briquettings for coil pressing, and the briquetting in described coil upper end face is arranged in outside hub of a spool and the transformer line of centres 120 ° of circumferential areas that are angular bisector.
Further, described coil lower surface is provided with four equally distributed briquettings, and the angle between adjacent two briquettings is 90 °.
Further, also comprise the upper clamping piece and lower clamping piece that are arranged on three coil upper and lowers, described upper clamping piece is connected with briquetting by nail pressing with lower clamping piece.
The beneficial effects of the utility model are: a kind of three-dimensional wound core dry type transformer with excellent heat dispersion performance that the utility model adopts, the briquetting in coil upper end face is arranged in outside hub of a spool and the transformer line of centres 120 ° of circumferential areas that are angular bisector, accelerate the heat radiation of transformer fe interior portion, thus improve the heat-sinking capability of transformer whole.
Accompanying drawing explanation
Be described further below in conjunction with accompanying drawing and example.
Fig. 1 is vertical view of the present utility model;
Fig. 2 is upward view of the present utility model.
Embodiment
See figures.1.and.2, a kind of three-dimensional wound core dry type transformer with excellent heat dispersion performance of the present utility model, comprise three coils 1 in vertical, three coil 1 arrangements triangular in shape, the upper and lower end face of each coil 1 is provided with some briquettings 2 for coil pressing 1, 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 is connected with briquetting 2 by nail pressing with lower clamping piece.Described coil 1 lower surface is provided with four equally distributed briquettings, angle between adjacent two briquettings 2 is 90 °, the briquetting 2 of described coil 1 upper surface is arranged in outside coil 1 center and the transformer line of centres 120 ° of circumferential areas that are angular bisector, avoid briquetting 2 to stop the heat radiation of transformer fe interior portion, thus improve the heat-sinking capability of transformer whole.
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.
