Abstract
The utility model discloses a synchronous switching alternate-current voltage stabilizing device which is suitable for various electric appliances using the voltage of 220 V. The synchronous switching alternate-current voltage stabilizer is composed of a fully automatic voltage stabilizer and a synchronous switch, wherein the voltage stabilizer can be turned on in order to realize the function of voltage stabilization when the switch of an externally connected electric appliance is turned on; when the externally connected electric appliance is turned off, the voltage stabilizer is turned off simultaneously, and thus, without the need of turning on or off the voltage stabilizer, people can directly turn on or off the externally connected electric appliance to simultaneously turn on or off the voltage stabilizer.
Description
The present invention relates to a kind of improved AC voltage regulator, the particularly a kind of full-automatic voltage stabilizer that can realize synchro switch.Be applicable to each electric appliances of 220V voltage.
Existing full-automatic voltage stabilizer is controlled by switch in use, when external connection electrical apparatus will be opened, should open voltage stabilizer earlier, again over circuit closer, after closing external connection electrical apparatus, need close voltage stabilizer again, sometimes forget the pass voltage stabilizer, not only waste electric energy, also influence the life-span of voltage stabilizer, therefore, make the people feel very bothersome.
Task of the present invention is that a kind of full-automatic voltage stabilizer that can realize synchro switch will be provided.When external connection electrical apparatus opens or closes; Voltage stabilizer also opens or closes simultaneously.
Task of the present invention is finished as follows: the coil of voltage stabilizer inside communicates, input end and output terminal are also communicated, detect a transformer end of gang socket again by the output terminal serial connection, the other end of socket connects concentric line makes the socket two ends keep 220V voltage, when socket does not connect or do not open external connection electrical apparatus, the primary coil no current that detects transformer passes through, the non-inductive voltage of secondary coil triggers controllable silicon, controllable silicon ends, also with regard to not adhesive of relay and voltage stabilizer is not worked yet.When the external connection electrical apparatus of socket is opened switch, detecting transformer has electric current to pass through, the secondary electrical circle produces induced voltage and triggers the controllable silicon conducting, through power transformer step-down, rectification, filtering, make relay that electric adhesive be arranged, voltage stabilizer is connected concentric line and is worked, when input voltage changes, can the autostable output terminal be 220V voltage, realize the purpose of automatic voltage regulation and synchro switch.
Below with reference to accompanying drawing invention is described in further detail.
Fig. 1 is a circuit diagram of the present invention.
With reference to Fig. 1, by the synchro switch voltage stabilizer for forming for synchro switch in voltage stabilizer and the dot-and-dash line ［ 11 ］ in the dot-and-dash line ［ 2 ］, by opening or closing of synchro switch ［ 11 ］ control voltage stabilizer ［ 2 ］.Socket ［ 1 ］ connects the input end ［ 13 ］ of concentric line ［ 14 ］ and voltage stabilizer ［ 2 ］ respectively, and input end ［ 13 ］ and output terminal ［ 15 ］ communicate when voltage stabilizer is not worked.Synchro switch ［ 11 ］ is formed by detecting transformer ［ 10 ］, bidirectional triode thyristor ［ 9 ］ and relay circuit, and the primary coil of detection transformer ［ 10 ］ is serially connected between the end of the output terminal ［ 15 ］ of voltage stabilizer ［ 2 ］ and socket ［ 12 ］.When the primary coil that detects transformer has electric current to pass through, the conducting of induction voltage triggered bidirectional triode thyristor ［ 9 ］ is arranged in the secondary coil, make power transformer ［ 8 ］ energising, the alternating current of output 12V obtains the direct current of 12V through diode ［ 7 ］ rectification and electric capacity ［ 6 ］ filtering, at this moment, luminous and relay ［ 4 ］ adhesive of light emitting diode ［ 5 ］, normally opened contact ［ 3 ］ is connected, because the two ends of normally opened contact connect the bridging line ［ 16 ］ of concentric line ［ 14 ］ and voltage stabilizer ［ 2 ］ respectively, voltage stabilizer is switched on and starts working at this moment, realizes the function of its automatic voltage regulation.The elementary circle that detects transformer ［ 10 ］ is serially connected between voltage stabilizer ［ 2 ］ and the socket ［ 12 ］, because impedance is less, the pressure drop of generation is also very little, can not influence the voltage at socket ［ 12 ］ two ends.When the primary coil of detection transformer ［ 10 ］ does not have electric current to pass through, secondary coil does not produce induced voltage, and bidirectional triode thyristor ［ 9 ］ ends, and relay ［ 4 ］ dead electricity disconnects contact ［ 3 ］, voltage stabilizer cuts off the power supply and does not work, and this moment, socket ［ 12 ］ two ends kept 220V voltage.
During use, socket ［ 12 ］ connecting circuit, when external connection electrical apparatus was opened, voltage stabilizer ［ 2 ］ was also open-minded simultaneously; When external connection electrical apparatus disconnected, voltage stabilizer ［ 2 ］ also disconnected simultaneously.
