The invention provides a kind of tapped self coupling type AC voltage regulator based on segmentation variable cross-section winding, comprise winding, described winding is one to have the winding of a plurality of taps, described a plurality of tap is divided into a plurality of sections with winding, the cross-sectional area of described each section has nothing in common with each other, and namely winding is selected the different line footpath of thickness for use.
Embodiment 1: manual type is based on the tapped self coupling type AC voltage regulator of segmentation variable cross-section winding;
The tapped self coupling type AC voltage regulator of manual type segmentation variable cross-section winding as shown in Figure 1, the output of tapped self coupling type AC voltage regulator is connected to the tap (any among the 1-8) of winding by voltage-regulation tap changer K, and wherein voltage-regulation tap changer K is on sale on market.
Embodiment 2: adopt the electronic control type of single-chip microcomputer based on the tapped self coupling type AC voltage regulator of segmentation variable cross-section winding;
The electronic control type that adopts single-chip microcomputer based on the major loop schematic diagram of the tapped self coupling type AC voltage regulator of segmentation variable cross-section winding as shown in Figure 2, namely the break-make by control relay realizes pressure regulation.
Its control circuit can have multiple embodiments, can all adopt pure hardware to realize, also can adopt single-chip microcomputer to add that the form of the software and hardware combining of peripheral component realizes.Present embodiment is example with the control circuit that adopts single-chip microcomputer, and as shown in Figure 3, it mainly comprises key circuit, governor circuit, drive circuit and a plurality of relay; Key circuit links to each other with governor circuit, and governor circuit links to each other with drive circuit, and drive circuit links to each other with a plurality of relays; A plurality of relays link to each other with a plurality of taps of winding respectively, are used for the break-make of the described tap of control; One end of the normally opened contact of a plurality of relays links together.
Among Fig. 4, JD0～JD7 is the relay of 8 12V, the J0～J7 of its corresponding normally opened contact in Fig. 2.U4 is ULN2803, is the high-voltage great-current darlington array of 8 passages, and its inner Y0～Y7 is the rp-drive of 8 OC doors (or OD door), and the withstand voltage of the output triode of this OC door is 50V, and driving force is 500mA.U1 is 51 Series chip (other type single-chip microcomputers also can).C1 and R1 constitute high effectively electrify restoration circuit, and powered on moment is for the reset pin RST of single-chip microcomputer U1 provides an of short duration high level that resets.The 8 parallel-by-bit interface P1(P0.0 of U1～P0.7) are U2(74LS273) input drive signal is provided.U2 is the 8D latch, can adopt 74LS273(or 74HC273), play logic buffering and data and latch effect, its detailed action principle hereinafter describes in detail.R4 and C2 are low effective electrify restoration circuits, are U2(74LS273) clear terminal (
) a low effective power-on reset signal is provided, make U2 guarantee to be zero in powered on moment output.Capacitor C O1, CO2 and crystal oscillator X constitute crystal oscillating circuit, and the oscillator signal that produces 12MHz is given single-chip microcomputer U1.R2 and K1, R3 and K2 form key circuit, for single-chip microcomputer U1 provides low effectively by key input signal.K1 may be defined as " increasing 1 " button, and K2 may be defined as " subtracting 1 " button.The P1 mouth of single-chip microcomputer U1 is used for to display provides the driving signal, and display can adopt the LED display module, can also adopt the LCD display module.U3-A is an inverter, utilizes 7404(or 74LS04, or 74HC04 also can) of six inverters gets final product in the chip.The write signal of single-chip microcomputer
(effectively low) is anti-phase through the U3-A inverter, for U2 provides an effective write signal of rising edge.
The operation principle of the tapped self coupling type AC voltage regulator based on segmentation variable cross-section winding of the present invention is as follows:
At first set forth the logic cushioning effect of U2.If there is not the logic cushioning effect of U2, because single-chip microcomputer its port P0 when firm powering on is output as entirely " 1 " (P0=FFH=11111111B), this complete " 1 " signal (8 high level) will directly be added in U4(ULN2803) input, can cause the inner Y0～Y7 of U4 to be output as low, thereby make all adhesive actions of eight relays, and then whole closed eight short circuit in windings that can make automatic coupling voltage regulator simultaneously of their normally opened contact J0～J7, this can burn whole voltage regulator.So should be any moment, or J0～J7 all disconnects, or only have one to be closure state, all the other be off-state.Adopt after the U2, just can solve the problem of the full adhesive of powered on moment relay.Single-chip microcomputer powered on moment, the reset circuit of U2 (R4 and C2) be U2 clear terminal (
) a low effective power-on reset signal is provided, make U2 be output as " 0 " (Q entirely
7～Q
0=00H=00000000B), thus 8 OC gate drivers that make U4 inside are all by disconnecting, and then 8 relays are all cut off the power supply, its 8 normal opened contact J7～J0 are not closed, output voltage U
O=0.
Simultaneously, the reset circuit of U1 (R1 and C1) resets single-chip microcomputer for the reset terminal of U1 (RST) provides a high effective power-on reset signal, program brings into operation from initialization section, writes entirely " 0 " (P0=00H) to the P0 mouth at first immediately, this moment write signal be low (
=0) make the CLK end of U2 obtain a rising edge triggering signal, enter into U2(74LS273 thereby P0 mouth data (be 8 complete " 0 " this moment) are latched) output (Q
7～Q
0=00H=00000000B).
As seen from Figure 2, output voltage is according to one grade of 50V, increasing or decreasing.Whenever press K1 key (" UP " increases key) next time, voltage increased progressively one-level (increasing 50V) more originally, pressed the K1 key again this moment up to reaching highest 400V(, and 400V is motionless in the output maintenance).Whenever press K2 key (" Down " reduces key) next time, the voltage one-level (reducing 50V) of successively decreasing is more originally pressed the K2 key this moment again up to reaching lowermost level 0V(, and output keeps the 0V motionless).
Under the control of program, monitor the state of K1 and K2 all the time, and determine output voltage to increase progressively or action such as successively decrease according to their state.And output voltage is presented on the display.
Output voltage U
OWith relay contact (J7～J0) export data (Q with the U2 chip
7～Q
0) between corresponding relation as shown in table 1 below.
