Detailed description of the invention
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the induction hardening transformer of a kind of new construction, including connection seat, tagblock group, coupling block group, primary coil group, connecting tube, connection copper coin, connect post group, iron core, resin;Iron core uses iron-base nanometer crystal alloy to make, and iron core is made up of multiple core bodys 1 being superimposed, and the cross section of core body 1 is rectangular ring;Primary coil component is the first primary coil 2 and the second primary coil 3, first primary coil 2 and the second primary coil 3 are wound on iron core, first primary coil 2 and the second primary coil 3 are symmetrical set, and the first primary coil 2 and the second primary coil 3 are connected into a loop;Tagblock group is used for accessing primary current, i.e. tagblock component is positive terminal block 4 and negative terminal block 5, and positive and negative electrode tagblock positive and negative electrode with primary coil group respectively is connected;Connecting tube 6 is coiled in the outside of primary coil group, it is provided with gap between connecting tube 6 and primary coil group, two connect copper coin 7 and are both secured in connecting tube 6, two connect copper coin 7 and are distributed around primary coil group symmetrically formula, connecting post component is positive terminal 8 and negative terminal 9, connecting tube 6 is just, negative pole two ends respectively with positive terminal 8, negative terminal 9 connects, connecting tube 6, connect copper coin 7 and connect post group three and link together composition secondary coil, secondary coil exports secondary current by coupling block group, i.e. coupling block component is positive pole coupling block 10, negative pole coupling block 11, just, negative terminal respectively with just, negative pole coupling block connects;By resin 12 by tagblock group, coupling block group, primary coil group, connecting tube 6, connect copper coin 7, connect post group, iron core and be cast into the transformator of integral type, and insulated by resin bed between primary coil group and secondary coil;Two nose ends of connecting tube 6 all extend to outside resin-case, it is equipped with union joint 13 on two nose ends of connecting tube 6, union joint 13 is connected with coolant apparatus, in making connecting tube 6, flowing has recirculated cooling water, connection seat 14 is assemblied on one end of transformator, connection seat 14 is connected with support by floating connecting structure, i.e. floating connecting structure is: the connection end of connection seat 14 is provided with pin shaft hole 15, is provided with connection bearing pin in pin shaft hole.
Described transformator circulating cooling part may be used without two connecting tubes 6, and two connecting tubes 6 are for being arranged side by side, and coil respectively.
Operation principle: by the electromagnetic induction between primary coil group and secondary coil, is converted into another voltage gradation and the electric current of same frequency by the alternating voltage of a certain grade and electric current;It is delivered on load equipment (quenching induction installation) through connecting tube, connection post group, coupling block group by connecting the voltage and current of copper coin conversion;Connecting tube is applied not only to turn on electric current, is also used for cooling down transformator, and connecting Bottomhole pressure has recirculated cooling water.
The characteristic of iron-base nanometer crystal alloy:
1. high saturated magnetic induction: the Bs of iron-base nanometer crystal alloy reaches 1.2T, is more than ferritic twice.As common mode inductance iron core, it is saturated that important principle is that iron core can not be magnetized into, and otherwise inductance value drastically reduces.And in actual applications, the interference strength having many occasions is relatively big (such as high-power frequency conversion motor), if with common ferrite as common mode inductance, there is saturated probability in iron core, it is impossible to ensures the noise suppression effect under the interference of big intensity.Due to the high saturated magnetic induction of nanometer crystal alloy, its anti-saturation characteristic is substantially better than ferrite undoubtedly so that nanometer crystal alloy is highly suitable for the strongly disturbing occasion of heavy current;2. the temperature stability of brilliance: the Curie temperature of iron-base nanometer crystal alloy is up to more than 570 DEG C.In the case of having bigger temperature fluctuation, the performance rate of change of nanometer crystal alloy is significantly lower than ferrite, has excellent stability, and the change of performance is close to linearly.Usually, nanometer crystal alloy is at-50 DEG C---and in the temperature range of-130 DEG C, the rate of change of main magnetic property is within 10%.By contrast, ferritic Curie temperature is typically below 250 DEG C, and magnetic property rate of change is sometimes up to more than 100%, and in non-linear, is difficult to compensate.This temperature stability of nanometer crystal alloy combines its distinctive low loss characteristic, provides loose temperature conditions for device designer.Frequency characteristic the most flexibly: by different manufacturing process, nanocrystalline iron core can obtain different frequency characteristics, coordinates suitable coil turn can obtain different impedance operators, meets the filtering requirements of different-waveband, and its resistance value is much higher than ferrite.It it is noted that any wave filter all can not look to just can realizing with a kind of core material the noise suppressed of whole frequency range, but different core material, size and the numbers of turn etc. should be selected according to the filtering frequency range of filter specifications.Compared with ferrite, nanometer crystal alloy can obtain required frequency characteristic by adjusting process more neatly.
Do not elaborate in this specification part, for techniques known.
