The utility model discloses a three -dimensional book of silicon steel 20kV unshakable in one's determination open -type dry -type transformer unshakable in one's determination arranges the briquetting of coil up end outside using hub of a spool and the 120 circumference regions of transformer line of centres as angular bisector for the inside heat dissipation of transformer core, thus the holistic heat -sinking capability of transformer improved.
Description
Technical field
The utility model relates to a kind of dry-type transformer, particularly relates to the good silicon steel of a kind of heat dispersion 20kV three dimensional wound core unshakable in one's determination open 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 °.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.Therefore, how strengthening the heat dispersion of three dimensional wound core transformer, is a problem needing solution badly.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is the silicon steel 20kV three dimensional wound core unshakable in one's determination open dry-type transformer providing a kind of heat dispersion good.
The utility model is the technical scheme solving the employing of its technical problem:
A kind of silicon steel 20kV three dimensional wound core unshakable in one's determination open dry-type transformer, comprise the three dimensional wound core be put together by three silicon steel chases, described three dimensional wound core is vertical triangulation shape, three dimensional wound core there are around the home three coils, 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; Also blowing device is provided with around described coil.
Further, described blowing device comprises multiple stage blower fan.
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:
Silicon steel of the present utility model 20kV three dimensional wound core unshakable in one's determination open dry-type transformer, 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.
