Description

Superhigh radiating iron core
Technical field
This practical new technology relates to a kind of transformer iron-core structure, particularly relates to all kinds of transformer cores such as 10KV-550KV dry-type transformer, oily formula transformer, reactor, rectifier transformer, mining transformer.
Background technology
As long as transformer one is energized, transformer core and coil all can production heat-dissipating amounts, and heat excessive and time can make the accelerated ageing of transformer coil insulated material for a long time, causes interlayer or turn-to-turn short circuit, thus cause transformer damage to run time serious.
Under normal circumstances, traditional transformer iron core manufacturing structure is all to adopt with main to secondary as descending formula structure, this technology adopt with main to secondary be wave structure, increase iron core area of dissipation this technology effective, temperature is eliminated by iron core self, thus reach effect that transformer whole temperature rise declines, extend transformer service time.
Summary of the invention
This practical technique is reasonably to increase transformer core area of dissipation, and transformer whole temperature rise is declined, and extends transformer service life.
Technical scheme of the present invention is as follows:
A kind of superhigh radiating iron core, comprise folder, iron core, screw rod, nut, meson, insulated column, folder base, feet wood, it is characterized in that, described iron core becomes awave lamination silicon steel sheet to form by multilayer size.Meson and insulation spacer.Each layer laminate silicon steel sheet is formed by stacking by the silicon steel sheet of some pieces of same dimension specifications, and the dimensions between different lamination silicon steel sheet is different.
Be provided with screw rod between described lamination silicon steel sheet, screw rod two ends are provided with folder and are fixed by nut, between folder and nut, be provided with meson.
From center laterally, its height H totally becomes wave to successively decrease to described every layer laminate silicon steel sheet.
From center laterally, its width L totally becomes wave to successively decrease to described every layer laminate silicon steel sheet.
Described folder and HV Terminal, be provided with insulated column between HV Terminal and low-voltage terminal.
Described HV Terminal is connected with high-tension coil, and low-voltage terminal is connected with low-voltage coil, and low-voltage coil and high-tension coil are all wrapped in outside iron core, and low-voltage coil is positioned at high-tension coil inside.
The folder of described iron core lower end is fixed on feet wood, and feet wood is contained on folder base.
The invention has the beneficial effects as follows: by changing the radiating effect of original transformer core, increasing iron core area of dissipation, effectively control the temperature reducing transformer core radiating surface, thus reduce transformer temperature rise, reach and extend transformer useful life.

Embodiment
For being illustrated more clearly in content of the present invention, be further described below in conjunction with the drawings and specific embodiments.
As shown in Fig. 3, Fig. 5, traditional transformer iron core manufacturing structure is all adopt from main to secondary for descending formula structure, and namely from core interior lamination silicon steel sheet 21 laterally, its height H, width L present successively and successively decrease.
As shown in Figure 1, Figure 2 and Figure 4, superhigh radiating iron core comprises folder 1, iron core 2, screw rod 3, nut 4, meson 5, insulated column 6, folder base 7, feet wood 8, meson 5 i.e. insulation spacer, described iron core 2 becomes awave lamination silicon steel sheet 21 to form by multilayer size.Each layer laminate silicon steel sheet 21 is formed by stacking by the silicon steel sheet of some pieces of same dimension specifications, and the dimensions between different lamination silicon steel sheet 21 is different.Be provided with screw rod 3 between lamination silicon steel sheet 21, screw rod 3 two ends are provided with folder 1 and are fixed by nut 4, and between folder 1 and nut 4, be provided with meson 5, meson 5 is insulation spacer.From center laterally, its height H totally becomes wave to successively decrease to every layer laminate silicon steel sheet 21.From center laterally, its width L totally becomes wave to successively decrease to every layer laminate silicon steel sheet 21.Folder 1 and HV Terminal 92, be provided with insulated column 6 between HV Terminal 92 and low-voltage terminal 94.HV Terminal 92 is connected with high-tension coil 91, and low-voltage terminal 94 is connected with low-voltage coil 93, and low-voltage coil 93 and high-tension coil 91 are all wrapped in outside iron core 2, and it is inner that low-voltage coil 93 is positioned at high-tension coil 91.The folder 1 of iron core 2 lower end is fixed on feet wood 8, and feet wood 8 is contained on folder base 7.
As shown in Figure 6, superhigh radiating iron core is arranged on the position assumption diagram after transformer, and three-phase transformer comprises three groups of iron cores 2.During use, shear all kinds of different length and width silicon steel sheet according to design drawing, the safety problem that iron core is produced all kinds of metal object can be controlled rationally and effectively, and low to this technical security production costs of metal object such as coil, screw rod, tank wall, case lid, boatswain chairs.
Above-described embodiment can not think limiting the scope of the invention, the change that those skilled in the art make based on technical scheme of the present invention or means or improvement, within the protection range that all should fall into the claims in the present invention.
