Embodiment
Be described further below in conjunction with accompanying drawing.The tap number of autotransformer 2 is 6, and Ui is an input voltage, and U0 is an output voltage, and Δ U is a bucking voltage, changes the voltage stabilized range that compensator transformer 1 transformation ratio can change voltage stabilizer, and the tap number that changes autotransformer 2 can change the precision of voltage regulation.
Embodiment one: the utility model is achieved like this: as seen from Figure 2, compensator transformer 1 elementary winding is for being with tapped double winding, center tap connects output terminal N point, promptly divide and just compensating winding 11 and counterbonification winding 12, the technical parameter unanimity of two windings, the input voltage of two windings are all by output voltage U 0 design; Compensating switch selects controllable silicon, and controllable silicon SZ, controllable silicon SF when controllable silicon SZ is in conducting state, can obtain different positive bucking voltage+Δ U with one of them switched conductive of controllable silicon (S1, S2, S3, S4, S5) as the main switch of positive and negative compensation; When controllable silicon SF is in conducting state, can obtain different negative bucking voltage-Δ U with one of them switched conductive of controllable silicon (S1, S2, S3, S4, S5).When controllable silicon SZ and controllable silicon SF conducting simultaneously is zero-compensation, and controllable silicon this moment (S1, S2, S3, S4, S5) is blocking state, and autotransformer 2 is equivalent to a telefault and equalizing network is irrelevant.
Embodiment two: the utility model also can be achieved like this: increase a controllable silicon S0 as the zero-compensation switch in Fig. 2, as shown in Figure 3, controllable silicon S0 is connected across and just compensates between winding 11 ends of the same name and counterbonification winding 12 non-same polarities, in positive and negative compensation handoff procedure, can make the zero-compensation middle transition by controllable silicon S0, make switching more reliable.
Embodiment three: the utility model can also be realized like this: as seen from Figure 4, compensator transformer 1 is elementary to be simplex winding, compensating switch selects controllable silicon, controllable silicon (SZ1, SF1, S0, SZ2, SF2) bridge-type connects, controllable silicon S0 is the zero-compensation switch, positive compensating switch is by controllable silicon (SZ1, SZ2) form, negative compensating switch is by controllable silicon (SF1, SF2) form, controllable silicon (SZ1, SF2, S0) and contact connect the elementary end of the same name of compensator transformer 1, controllable silicon (SZ2, SF1, S0) and contact connect the elementary non-same polarity of compensator transformer 1, controllable silicon (SZ1, SF1) also contact meets controllable silicon (S1, S2, S3, S4, S5) also contact, controllable silicon (SZ2, SF2) and contact connect the N point of autotransformer 2 output terminals.Just, in the negative compensation handoff procedure, under the controllable silicon S0 conducting state to just compensating or during negative compensation conversion, positive compensating switch or negative compensating switch are realized conversion under no current state, stopped because the output voltage direct short-circuit phenomenon that compensating switch has misleaded and causes when switching: compensate-state (controllable silicon (SZ1 of shelves if voltage stabilizer just is in, SZ2, S1) conducting), if rising, output voltage surpasses 220V, will transfer counterbonification to, turn-off controllable silicon (SZ1 this moment, SZ2, S1), connect controllable silicon S0, connect controllable silicon (SF1, SF2, S1), disconnect controllable silicon S0 again, just finished from just compensating to the conversion process of counterbonification.Otherwise, transfer by counterbonification that just to compensate also be similar to.Since each switch compensating switch all is at controllable silicon (S1, SZ1, SZ2) to controllable silicon S0, again by controllable silicon S0 to controllable silicon (S1, SF1, SF2), stopped the common-mode conducting in the positive and negative compensation handoff procedure and output terminal (between the U.N) short circuit that forms.
