Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of embodiment of the present invention relay energy-saving control circuit.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the circuit theory schematic diagram of embodiment of the present invention relay energy-saving control circuit.The relay energy-saving control circuit of the present embodiment comprises photoelectrical coupler U, the first resistance R1, the second resistance R2, the 3rd resistance R3, the 4th resistance R4, the 5th resistance R5, the first triode Q1, the second triode Q2, the first electric capacity C1, the second electric capacity C2, voltage stabilizing didoe VD, relay coil J, the first diode D1, the second diode D2, light-emitting diode D3 and the 6th resistance R6.
Wherein, photoelectrical coupler U has two inputs and two outputs, one end of an input termination first resistance R1, another termination control signal of first resistance R1, another input end grounding, one exports termination bias voltage Vb, and another output connects the base stage of the first triode Q1 by the second resistance R2.
The grounded emitter of the first triode Q1, the collector electrode of the first triode Q1 and the anode of voltage stabilizing didoe VD are connected with one end of the second electric capacity C2 and are connect the base stage of the second triode Q2 by the 4th resistance R4, the negative electrode of voltage stabilizing didoe VD is connected with the anode of the other end of the second electric capacity C2 with one end of relay coil J and the first diode D1, the other end of relay coil J and the negative electrode of the first diode D1 connect the negative electrode of the second diode D2, the anode of the second diode D2 meets supply voltage VDD, the negative electrode of light-emitting diode D3 connects the anode of the first diode D1 by the 6th resistance R6, the anode of light-emitting diode D3 connects the negative electrode of the first diode D1, the emitter of the second triode Q2 meets supply voltage VDD, the collector electrode of the second triode Q2 is by the 5th resistance R5 ground connection, between the base stage that 3rd resistance R3 is connected on the second triode Q2 and emitter, first electric capacity C1 is connected between the collector electrode of the second triode Q2 and the negative electrode of the second diode D2.In the present embodiment, supply voltage VDD is 24V, and bias voltage Vb is 5V.
During the work of relay energy-saving control circuit, control signal isolates amplification through photoelectrical coupler U, the output of photoelectrical coupler U provides base current for the first triode Q1, before making the first triode Q1 conducting, supply voltage VDD charges to the first electric capacity C1 by the second diode D2, the 5th resistance R5, through certain hour, the first electric capacity C1 both end voltage equals supply voltage VDD.Base current is provided for the first triode Q1 in the output of photoelectrical coupler U, after making the first triode Q1 conducting, second triode Q2 also conducting, supply voltage VDD is superposed with the first electric capacity C1 both end voltage by the first triode Q1, power to relay coil J, the normally opened contact of relay is closed, normally-closed contact disconnects to make relay have enough large the suction-combining force to make.Through after a while, the first electric capacity C1 discharge off gradually, both end voltage is about 0V, and now, only supply voltage VDD powers to relay coil J, and relay is in energy conservation state.Simultaneously, because the voltage at the second electric capacity C2 two ends can not suddenly change, along with the second electric capacity C2 both end voltage be elevated to the voltage of voltage regulation of voltage stabilizing didoe VD gradually time, the voltage that voltage stabilizing didoe VD starts working and relay coil J two ends are born is the voltage of voltage regulation that supply voltage VDD deducts voltage stabilizing didoe VD. thus under being operated in ME for maintenance after making relay adhesive, to reach the object of the power consumption reducing relay, thus can reduce caloric value and increase the service life.
In addition, because relay major part is mounted in the inside of machine, its operating state is not directly perceived, by circuit of by four resistance R4 and light-emitting diode D2 being connected in parallel at the two ends of relay coil J, when relay coil J is energized, light-emitting diode D2 is bright, thus can understand the operating state of relay intuitively.
By the way, control signal isolation is amplified by photoelectrical coupler by the relay energy-saving control circuit of the embodiment of the present invention, control signal can be made more stable, and between the collector electrode being connected on the first triode after voltage stabilizing didoe and Capacitance parallel connection and relay coil, under being operated in ME for maintenance after can making relay adhesive, thus reach the object of the energy consumption of saving relay.
