Of the invention to have load stepless voltage regulation energy-economic transformer, its specifically used method is as follows：
The present apparatus can be made the pressure regulator of single-phase, multiphase and three-phase, can make the pressure regulator of dry type or oil immersion.
The formula E=4.44FwB that conversion according to law of electromagnetic induction formula is obtainedmS10-8（Wherein E is electromotive force, unit
It is V；F is ac frequency, unit is Hz；W is coil turn；BmFor magnetic flux density maximum, unit are Gs, S has for iron core
Effect sectional area, unit are cm2）Learn, electromotive force E can be changed by iron core net sectional area S in change formula, so as to carry out
Pressure regulation, by taking three-phase slide transformer structure as an example, it is upper mover 3, the lower structure of stator 2, by mover winding iron core 5 with it is quiet
Relative motion between sub- winding iron core 4 changes the relative area size between two iron cores, so as to reach change effective cross-section
The purpose of product S, as shown in figure 1, when the end face mover winding corresponding with mover 3 of the stator winding iron core 4 being located on stator 2
When the end face of iron core 5 is completely superposed, electric current such as is passed through to the primary winding in the stator coil 6 of the leftmost side, then stator winding iron
Core 4 will induce magnetic flux, and magnetic flux enters D by A, and through G, P to H, in H point minute two-way, a route H enters B through E, then returns to A through K, J,
Complete the first closed magnetic circuit；Another route H enters C through Q, I to F., and returning to A after L, K, J completes the second closed magnetic circuit, other
Two facies principles are identical, and under this state, the whole magnetic fluxs of stator winding iron core 4 are all sensed on corresponding mover winding iron core 5, so
The now induced voltage highest of mover coil 7, present apparatus output voltage also highest.
As shown in Fig. 2 stator 2 is slided, mover winding iron core 5 thereon moves on to the end face and mover of stator winding iron core 4
It is quiet by taking the stator winding iron core 4 of the leftmost side as an example when the end face of winding iron core 5, mover point magnetic core 10 respectively accounts for the position of half
By being divided into two-way after its end face, by being divided into two-way after A end faces, a route A enters D to the produced magnetic flux of sub- winding iron core 4,
Through G to P, there is half on this road by D because of the main flux that A is produced, therefore induced voltage is sensing full voltage on secondary coil 4
Half；Another road, M to P is entered by A, and this road is because of coil on M, so magnetic circuit by-passing is only completed, by P points of four tunnels；The first via
Enter B through H, E by P, secondary route P through H, Q, N, enter B, two route B simultaneously return to A the first closed magnetic circuits of completion through K, J afterwards all the way, the
Three route P enter C through H, Q, I, F, and the 4th route P enters C through H, Q, I, R, O, and two route C simultaneously return to A completions the through L, K, J afterwards all the way
Two closed magnetic circuits, other two facies principles are identical.So in the end face and mover winding iron core 5, mover point magnetic of stator winding iron core 4
When the end face of iron core 10 respectively accounts for half position, the magnetic flux of stator winding iron core 4 has half to sense mover winding iron core 5, mover line
The induced voltage that circle 7 is obtained is the half of full voltage, and now present apparatus output voltage is pressure regulation voltage 1/2nd.
As shown in figure 3, stator 2 continues to slide, it moves to the end face and corresponding mover point magnetic for making stator winding iron core 4
When the end face of iron core 10 is completely superposed, then whole magnetic fluxs that stator winding iron core 4 is produced enter mover point magnetic core by its end face
10 end face, by taking leftmost side stator winding iron core 4 as an example, whole magnetic fluxs that the stator winding iron core 4 is produced enter M by A end faces
End face, two-way is divided into through P, H to Q by Q, and a route Q to N enters B and returns to A through K, J, completes the first closed magnetic circuit；Another route Q
Through I, R to O, enter C and return to A through L, K, J, complete the second closed magnetic circuit, other two facies principles are identical.So in the mover of stator 2
When the end face that winding iron core 5 moves on to end face and mover point magnetic core 10 for making stator winding iron core 4 is completely superposed, stator winding iron
The magnetic flux that core 4 is produced is all without by mover winding iron core 4, therefore the non-inductive voltage of mover coil 7, the now output of the present apparatus
Voltage is zero.
Rotary transformer is identical with the operation principle of slide transformer.
