Power supply changeover device itself is also an electrical equipment, and when being connected on the electrical equipment on power supply changeover device and not working, it also can the loss of generation current, waste electric energy.
Power supply changeover device is connected to a large amount of electrical equipment, these electrical equipment adopt integrated device mostly, an electromagnetic field can be produced around it while thunder and lightning produces, this electromagnetic field inducing is on appliance circuit, a powerful electromotive force will be produced, this electromotive force scurries into electrical appliance by power circuit, is enough to damage circuit.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rational in infrastructure, power supply changeover device that triggering and conducting control ability is strong, easy to use with quick, energy-conservation.
Content of the present invention is: a kind of intelligent lightning protecting power saving power transducer, comprising:
Trigger control circuit, comprising can the monostable control circuit of repeated trigger and not reproducible monostable control circuit, described not reproducible monostable control circuit comprises delay circuit and NE555 integrated circuit, delay circuit comprises resistance R25 and electric capacity C15, described resistance R25 is connected between NE555 ic power input and signal trigger end, described electric capacity C15 is connected between NE555 integrated circuit signal trigger end and cold end, and the high-triggering end of NE555 integrated circuit is connected delay circuit with discharge end;

Relay drive circuit, comprise relay and triode, the base stage of described triode connects the drive singal output of trigger control circuit, and the control signal input of collector connection relay also connects the power input of relay by voltage stabilizing didoe D6, emitter connects electronegative potential;
Power circuit, for trigger control circuit and relay are powered;
Protective circuit is thunderbolt current foldback circuit, in parallel with power circuit.
Preferably, described triode is NPN type triode.
Preferably, described power circuit is two conversion electric power circuit, comprises power choke coil, polypropylene capactive, resistance and three-terminal voltage-stabilizing circuit, generates the DC power supply of 5V and 24V, the DC power supply of 5V is connected with trigger control circuit, and the DC power supply of 24V is connected with relay.
The invention has the beneficial effects as follows, the present invention mainly from the current minimizing wasting of resources and be convenient for people to application with life, digital device is adopted to carry out the mode of control simulation device, digital circuit work is only had and high-tension analog circuit does not work in normality, thus decrease the waste of power, another aspect sound and these common trigger sources infrared, as triggering, make people use not only simple but also quick.
The present invention can be divided into five parts structure, as shown in Fig. 1, Part I is mainly made up of power choke coil, polypropylene capactive, resistance and three-terminal voltage-stabilizing circuit and the final DC power supply generating 5V and 24V, 24V as relay conducting whether control voltage, 5V is as the operating voltage of chip.As shown in Fig. 2-3, Part II is made up of 74HC123 and NE555 two monostables, the former is can the monostable of repeated trigger, its trigger end has main frame power output to determine, when main frame has power stage, current transformer will induce a small electric current after the effect of two comparators and triode, a low level triggering will be given again at the end of the temporary stable state of 74HC123 is also incomplete, as long as thus realize host work relay will the phenomenon of conducting always, NE555 then becomes the most basic its trigger end of monostable circuit and is connected on the output with door CD4082.As shown in Fig. 4-6, Part III is the circuits for triggering of miaow head, switch and infrared remote receiver composition, their output be connected on four inputs with on door, be connected on monostable input of NE555 with the input of door.As shown in Fig. 7, Part IV is the switching circuit of relay, and as shown in Fig. 8, Part V is lightning prevention circuit.
The difference of the present invention and normally used power supply changeover device is to be not only functionally add acoustic control and infrared triggering as shown in Figure 3, the conducting of the relay simultaneously having monostable to control as shown in Figure 2, thus achieve the power dissipation reduced when main frame does not have electricity, so not only decrease the loss of the energy but also facilitate everybody life, the input-output equipment be simultaneously connected with main frame when host work also works simultaneously, if main frame does not work, monostable input of repeated trigger low level can be can't detect then in figure bis-, (resistance capacitance having monostable to connect determines) monostable arrives stable state after a while, relay is disconnected, thus make the input-output equipment of connection host computer complete power-off, reduce the power consumption of input-output equipment.
