This leakage field iron core is configured between winding and the secondary winding, prevents the magnetic core supersaturation of high-tension transformer by the flux leakage that makes the magnetic core of flowing through.
Yet, when induction high voltage on winding and secondary winding, can produce high heat, described high heat exerts an influence each other at winding and secondary winding, promptly, the transfer of heat that produces from winding is on secondary winding, from transfer of heat to the time winding of secondary winding generation, cause magnetic core overheated thus.
If magnetic core is overheated, will reduce transformer performance, therefore, developed the various radiator structures that prevent that magnetic core is overheated of being used to, but the above-mentioned leakage field iron core that is made of the silicon steel plate iron core only has the oversaturated function of the magnetic core of preventing.
Summary of the invention

Description of drawings
Fig. 1 is the stereogram with transformer of leakage field iron core in the past;
Fig. 2 to Fig. 6 is applicable to have according to the three-dimensional exploded view of winding element, E type magnetic core and the I type magnetic core of the transformer of the leakage field iron core that is laminated with heat-insulating material of the present invention and heat-insulating material is shown and the enlarged drawing of the stepped construction of leakage field iron core.
Embodiment
Below, describe the present invention with reference to the accompanying drawings in detail.
As shown in Figure 2, transformer has E type magnetic core 210, is wound with winding 240 one time on this E type magnetic core 210, keeps at a certain distance away on the top of this winding 240 to be wound with this winding 240 to compare the big secondary winding of turn ratio 250.
Both sides between winding 240 and secondary winding 250 have and are used to prevent the oversaturated leakage field iron core 260 of magnetic core, this leakage field iron core 260 forms by stacked rectangular flat shape iron core, has formed contact with leakage field unshakable in one's determination 260 and have form and a roughly the same heat-insulating material 270 of leakage field iron core on the uper side surface of this leakage field iron core 260.
This heat-insulating material 270 is made of the low-down material of conductive coefficients such as mica or plasterboard, even at high temperature also can not deform.
Extremely shown in Figure 5 as Fig. 3, both can be on leakage field iron core 260 and below the formation heat-insulating material, also can central authorities form heat-insulating material 270 and in the above with following formation leakage field iron core 260, in addition, as shown in Figure 6, also can leakage field iron core 260 is laterally erected form after, on one or both sides, form heat-insulating material 270.
As mentioned above, have up and down or the left and right sides stacked in the transformer of leakage field iron core 260 of heat-insulating material 270, if apply commercial voltage to a winding 240, will on secondary winding 250, respond to high voltage, at this moment, leakage field iron core 260 prevents the magnetic core supersaturation by the flux leakage that makes the magnetic core of flowing through, the heat that heat-insulating material 270 blocking-up are produced when responding to high voltage on magnetic core.That is, heat-insulating material 270 plays following effect: blocking-up being transmitted on the secondary winding 250 from the heat that winding 240 produces, and the heat that produces from secondary winding 250 of blocking-up is transmitted on winding 240.
If heat blocked by heat-insulating material 270 as described above, then can prevent the decline of the transformer performance that causes owing to high heat, consequently the size design of transformer can be got littler.
