Describe in detail according to the transformer 100 of the utility model embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, comprise magnetic core 10, roll 20, armature winding 30, secondary winding 40 and insulating part 50 according to the transformer 100 of the utility model embodiment.Magnetic core 10 has at least one magnetic core arm 11, and roll 20 is set on magnetic core arm 11.Armature winding 30 and secondary winding 40 difference windings are on roll 20, and armature winding 30 and the axially spaced layout of secondary winding 40 along roll 20.Between adjacent armature winding 30 and secondary winding 40, form clearance for insulation, form at least two clearance for insulations between multiple armature windings 30 and secondary winding 40, insulating part 50 is located on roll 20 and is positioned at clearance for insulation.
It should be noted that, between multiple armature windings 30 and multiple secondary winding 40, forming at least two clearance for insulations refers in the time that armature winding 30 arranges with secondary winding 40 is contiguous, armature winding 30 and two sides relative on secondary winding 40 are coaxial to be approached and spaced apart setting forms one group of phase proximal side, and in multiple armature windings 30 and multiple secondary winding 40, at least has the phase proximal side of two groups of coaxial approaching and spaced apart settings.
In magnetron drive power supply, for making power semiconductor load reduction, and conventionally adopt zero voltage switching technology (ZVS), this ZVS Technology Need is arranged on the coupling coefficient of step-up transformer between about 0.6 to 0.85, and this just requires there is stronger coupling between step-up transformer primary and secondary winding.
According to the transformer 100 of the utility model embodiment, by form at least two clearance for insulations between multiple armature windings 30 and secondary winding 40, make can to have between armature winding 30 and secondary winding 40 the phase proximal side at multiple coaxial close and intervals, armature winding 30 and the coupling performance of secondary winding 40 are improved, simultaneously by regulating the axial length of 40 each sections of primary and secondary windings, can make the coupling coefficient between armature winding 30 and secondary winding 40 bring up between 0.6 to 0.85, coupling performance improves greatly, without improving coupling performance by increasing the radially number of turn of armature winding 30 and secondary winding 40 and reducing axial winding length again, armature winding 30 and the radial windings number of plies of secondary winding 40 are reduced, the elongated formation flat of axis winding length structure, improve radiating efficiency, save material usage, and reduce the overall dimensions of transformer 100, space availability ratio is high, cost performance is high.
In correlation technique, it is coaxial configuration close to each other that the armature winding on transformer only has respectively a side with secondary winding, and coupling is poor.In order to improve coupling performance, conventionally need to increase the radially number of turn of armature winding and secondary winding, reduce the axial number of turn of armature winding and secondary winding, make thus the radial windings number of plies of whole armature winding and secondary winding increase, the axial winding number of plies reduces, and the overall dimensions of transformer is large and heat dispersion is poor; In the time increasing the radial windings number of plies of armature winding and secondary winding, can make the winding length of armature winding and secondary winding elongated, increase material cost.
And according to the transformer 100 of the utility model embodiment, coaxial approach and the number of the phase proximal side at interval is increased to two or more on armature winding 30 and secondary winding 40, make armature winding 30 and the coupling surface number of secondary winding 40 become many, it is large that coupling area becomes, coupling performance improves greatly, without the coupling performance that improves again transformer 100 by increasing the radially number of turn of armature winding 30 and secondary winding 40.
Thus, the radial windings number of plies that armature winding 30 and secondary winding 40 form is few, and axial winding length is long, and the needed total winding length of identical winding turns is shortened, and has saved wire rod consumption; The axial winding number of plies reduces simultaneously, makes the attenuation of line bag, has improved the heat radiation of transformer 100, has significantly reduced the overall temperature rise of transformer 100; And due to the reduction of temperature rise, can also reduce wire diameter, and further save the consumption of wire rod, reduce the material cost of transformer 100; In addition, the radial windings number of plies reduces, and the overall dimensions of transformer 100 has also been dwindled in the attenuation of line bag, is conducive to the miniaturization of whole driven by magnetron plate.
According to an embodiment of the present utility model, magnetic core 10 comprises two magnetic core arms 11, two magnetic core arms 11 are arranged spaced apart along the vertical direction, are respectively equipped with armature winding 30 and secondary winding 40 on each magnetic core arm 11, and armature winding 30 and secondary winding 40 vicinity and spaced apart settings.Thus, the armature winding 30 on two magnetic core arms 11 and secondary winding 40 all have the coaxial side arranging that approaches, and the space availability ratio of magnetic core 10 improves, and the coupling performance of transformer 100 strengthens.
Especially, in the time thering is respectively multiple spaced apart and contiguous armature windings 30 that arrange and secondary winding 40 on each magnetic core arm 11, on each magnetic core arm 11, can there are multiple coaxial approaching and spaced side, coupling performance is further improved.
Armature winding 30 can arrange as required with the quantity of secondary winding 40, for example, in an embodiment of the present utility model, armature winding 30 on each magnetic core arm 11 is odd number, secondary winding 40 is even number, and each armature winding 30 is located at respectively between two adjacent secondary winding 40.Thus, two sides that make each armature winding 30 coaxially approach and arrange with the side of adjacent secondary winding 40 respectively, and armature winding 30 increases with the coaxial number of sides that approaches setting of secondary winding 40, coupling performance raising.
Especially, when the quantity of armature winding 30 is during than few one of the quantity of secondary winding 40, between two adjacent armature windings 30, be provided with a secondary winding 40, between two adjacent secondary winding 40, be provided with an armature winding 30, armature winding 30 and coaxial multiple staggered and close being distributed on roll 20 of secondary winding 40, the side of each armature winding 30 all with coaxial the approaching and spaced apart setting in side of adjacent secondary winding 40, and the side of each secondary winding 40 two sides of outer end (on secondary winding 40 except) all with the coaxial approaching and interval setting in side of adjacent armature winding 30, make thus armature winding 30 and the coupling performance of secondary winding 40 further improve.
Armature winding 30 on each magnetic core arm 11 and the quantity of secondary winding 40 can be identical, also can be different, for example, in an embodiment of the present utility model, magnetic core arm 11 comprises two, and the armature winding 30 on a magnetic core arm 11 is odd number, and secondary winding 40 is even number, each armature winding 30 is located at respectively between adjacent two secondary winding 40, can be provided with a winding or two windings on another magnetic core arm 11.In the time that another magnetic core arm 11 is provided with a winding, this winding can be armature winding 30, also can be secondary winding 40; In the time that another magnetic core arm 11 is provided with two windings, two windings can be the armature winding 30 and the secondary winding 40 that are arranged along the axially spaced-apart of magnetic core arm 11.
As shown in Figure 1, magnetic core arm 11 comprises two, and the winding number on two magnetic core arms 11 equates.Each magnetic core arm 11 is provided with an armature winding 30 and two secondary winding 40, armature winding 30 is located between two adjacent secondary winding 40, between armature winding 30 and two secondary winding 40, form two clearance for insulations, insulating part 50 is two and is located at respectively in two clearance for insulations.Thus, the both sides of each insulating part 50 are respectively equipped with armature winding 30 and secondary winding 40, armature winding 30 and side contiguous and insulation mutually relative with insulating part 50 on secondary winding 40, have two coaxial contiguous and sides that arrange of insulating on a magnetic core arm 11, coupling performance is good.
As shown in Figure 2, magnetic core arm 11 comprises two, and the winding number on two magnetic core arms 11 is unequal.A magnetic core arm 11 is provided with an armature winding 30 and two secondary winding 40, armature winding 30 is located between two adjacent secondary winding 40, between armature winding 30 and two secondary winding 40, form two clearance for insulations, another magnetic core arm 11 is provided with an armature winding 30.
In example as shown in Figure 3, a magnetic core arm 11 is provided with an armature winding 30 and two secondary winding 40, another magnetic core arm 11 is provided with an armature winding 30 and a secondary winding 40, between armature winding 30 and secondary winding 40, is provided with insulating part 50.Owing to having two coaxial contiguous and sides that arrange of insulating on a magnetic core arm 11, therefore, the transformer 100 of above two kinds of structures still has good coupling performance.In other embodiment of the present utility model, armature winding 30 is even number, and secondary winding 40 is odd number, and each secondary winding 40 is located at respectively between adjacent two armature windings 30.Thus, two sides that make each secondary winding 40 coaxially approach and arrange with the side of adjacent armature winding 30 respectively, and armature winding 30 increases with the number of sides of the coaxial approaching setting of secondary winding 40, makes equally the coupling performance of transformer 100 increase.
Alternatively, magnetic core arm 11 can comprise two, and the armature winding 30 on a magnetic core arm 11 is even number, and secondary winding 40 is odd number, each secondary winding 40 is located at respectively between adjacent two armature windings 30, can be provided with a winding or two windings on another magnetic core arm 11.In the time that another magnetic core arm 11 is provided with a winding, this winding can be armature winding 30, also can be secondary winding 40; In the time that another magnetic core arm 11 is provided with two windings, two windings can be the armature winding 30 and the secondary winding 40 that are arranged along the axially spaced-apart of magnetic core arm 11.Be understandable that, the quantity of armature winding 30 and secondary winding 40 and distribution situation are not limited only to the above description, can also have other situations, are not described in detail at this.
The structure of magnetic core 10 can have multiple, and for example, magnetic core 10 can be formed as U-shaped substantially, and two magnetic core arms 11 can be integrally formed.Magnetic core 10 that this is integrally formed is easy to prepare and electromagnetic performance is better.In the time that magnetic core 10 is made up of the magnetic core of a U-shaped, can form the back-shaped magnetic circuit of open loop.
Alternatively, magnetic core 10 can be made up of two U-shaped magnetic cores, and the opening of two U-shaped magnetic cores can be oppositely arranged and the free end of two U-shaped magnetic cores is connected respectively.Thus, magnetic core 10 can be formed as the back-shaped magnetic structure of closed loop.Wherein, between two U-shaped magnetic cores, air gap can be set, with the ability of the anti-saturation of adjusting inductance and magnetic core.
