Embodiment
Be described in further detail below in conjunction with the accompanying drawing specific embodiments of the invention.
Please, the invention provides a kind of three dimensional wound core energy-economic transformer, adopt three dimensional wound core to make magnetic circuit referring to figs. 1 through shown in Figure 3; This three dimensional wound core is arranged with coil, utilizes variable flux voltage regulation, and coil is divided into fixed coil and low-voltage coil; The said fixed coil number of turn is fixed, and low-voltage coil can be exported with control voltage through the adjustment coil turn, and this low-voltage coil is electrically connected with this fixed coil and concentric placement; To form high-tension coil; Like the fixed coil number of turn is w4, and the low-voltage coil number of turn is w, and the high-tension coil number of turn is W=w+w4.As shown in Figure 1, A is an Input voltage terminal, and a is an output voltage terminal, and the input voltage of this three dimensional wound core energy-economic transformer is a steady state value u1 (high pressure), and output voltage u2 (low pressure) is a changing value, and excursion can be u2≤100%u1.
Wherein, the number of turn between X1 and the X2 is w1, and the number of turn between X2 and the X3 is w2, and the number of turn between X3 and the Xn is wn, and the number of turn between Xn and a is w3, and the number of turn between Input voltage terminal A and the output voltage terminal a is w4.Through adjusting the coil neutral point to X1, X2, X3 ... Xn can change the size of output voltage.The lead that w3, wn, w2, w1 circle adopt can reduce according to the rising of voltage gradually, adopts ladder to select lead for use, practices thrift the copper material consumption.
Again, high-tension coil is a whole winding, and low-voltage coil is the part of high-tension coil, when the coil neutral point transfers to Xn; The number of turn of low-voltage coil is w=w3, and output voltage u2 is minimum, and when the coil neutral point transferred to X3, output voltage raise; The number of turn of low-voltage coil is w=w3+wn, and when the coil neutral point transferred to X2, output voltage further raise; The number of turn of low-voltage coil is w=w3+wn+w2, and when the coil neutral point transferred to X1, output voltage u2 was maximum; The number of turn of low-voltage coil is w=w3+wn+w2+w1, and along with the increase of the number of turn, output voltage u2 raises gradually.Low-voltage coil is when the gear of different output voltages, and the number of turn of high-tension coil is W=w+w4, and W changes along with the variation of w, and wherein the w4 part is constant all the time.
When low voltage voltage constantly raise, its number of turn increased, and made that the magnetic flux density in the iron core reduces, and no-load loss descends significantly.
In present embodiment, can high-tension coil be divided into 2 parts, a part is w4, another part is w.These two parts can be made 1 coil with the w4 wire turn, and the w wire turn is made 1 coil transverse arrangement of turbo, realize being electrically connected with the outside again.As shown in Figure 2, the coil of w wire turn and the coil of w4 wire turn are placed with one heart, with the coil of w wire turn and a end short circuit of w4 wire turn, make the coil of w wire turn and the coil of w4 wire turn become a coil that is electrically connected again.
Like Fig. 3, the coil of the coil of w wire turn and w4 wire turn also can vertically be arranged, and is wound on the same mould, and the coil of w4 wire turn is positioned at the top of coil, behind the intact w4 wire turn of coiling, follow coiling w wire turn, and X1～Xn draws according to the number of turn w1～wn that calculates.To X1～Xn diverse location, promptly can realize different voltage outputs through the adjustment neutral point.
This coil adopts three dimensional wound core as magnetic circuit, and this unshakable in one's determination three is symmetrical, and it is little to have harmonic wave, and no-load current is little, the characteristics that no-load loss is little, and both combine, and make the three dimensional wound core energy-economic transformer possess significant binodal ability effect.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by the scope of claims of the present invention.
