Description
Technical field
This patent product relates to the energy-saving controller of a kind of direct current relay or contactor coil.
Technical background
Along with industrial expansion, use the place of D.C. contactor and relay more and more, particularly the D.C. contactor of big electric current and relay.But the control coil of these relays and contactor also needs big electric current to keep, and particularly the moment of relay, contactor, adhesive needs number to decuple the impact of keeping electric current especially.How to realize guaranteeing that big electric current adhesive, low current maintain operate as normal, this is the not good as yet technical problem that solves of prior art.
Summary of the invention
The purpose of the utility model just provides the energy-saving controller of a kind of direct current relay, contactor coil, and guaranteeing provides instantaneous impulse current when direct current relay, Contactor Starting, guarantees the energy of keeping that after the relay adhesive, can provide lower simultaneously.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of relay coil energy-saving controller; It is characterized in that: control signal is received the base stage of triode Q1 through resistance R 1; The grounded emitter of triode Q1, coil one end of the collector connecting relay K1 of triode Q1 and the negative terminal of resistance R 2 and voltage-stabiliser tube V3, the positive ending grounding of V3; The anode of another termination capacitor C 1 of the coil of relay K 1 and the negative terminal of diode V1, the positive termination power of diode V1; The other end of the base stage connecting resistance R2 of triode Q2 and the anode of diode V2, the collector electrode of triode Q2 connects power supply, and the negative pole of diode V2 connects power supply, and the emitter of triode Q2 links to each other with the negative terminal of capacitor C 1, the other end of resistance R 3; Control signal is received the base stage of triode Q3, the grounded emitter of triode Q3, the collector electrode connecting resistance R3 of triode Q3 through resistance R 4.
The advantage of the utility model mainly is when direct current relay, Contactor Starting, instantaneous impulse current to be provided, and has reduced the pressure of relay or contactor power supply; Coil is kept power consumption and is reduced significantly, improves system effectiveness.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model.
Embodiment
As shown in Figure 1; The relay coil energy-saving controller, its control signal is received the base stage of triode Q1, the grounded emitter of triode Q1 through resistance R 1; Coil one end of the collector connecting relay K1 of triode Q1 and the negative terminal of resistance R 2 and voltage-stabiliser tube V3, the positive ending grounding of V3; The anode of another termination capacitor C 1 of the coil of relay K 1 and the negative terminal of diode V1, the positive termination power of diode V1; The other end of the base stage connecting resistance R2 of triode Q2 and the anode of diode V2, the collector electrode of triode Q2 connects power supply, and the negative pole of diode V2 connects power supply, and the emitter of triode Q2 links to each other with the negative terminal of capacitor C 1, the other end of resistance R 3; Control signal is received the base stage of triode Q3, the grounded emitter of triode Q3, the collector electrode connecting resistance of triode Q3 through resistance R 4.
General relay and contactor are in the moment of adhesive; Need be several times as much as and normally keep electric current; In case and after relay (contactor) adhesive; Only need very low voltage can maintain attracting state, the technique scheme that the utility model provides proposes in order to satisfy above-mentioned requirements.
The physical circuit that provides below in conjunction with technique scheme and accompanying drawing is elaborated.
When control signal was low level, triode Q1 base stage was a low level, and triode Q2 base stage is a high level, so triode Q1, Q2 all are in off state; Triode Q3 base stage is a low level, and collector electrode is a low level, and VCC voltage is capacitor C 1 charging through diode V1, and through the time-delay of a bit of time, capacitor C 1 positive terminal voltage is charged on the current potential than the low diode V1 forward conduction voltage drop of VCC; Be changed to high level with control signal this moment, and triode Q3 turn-offs, triode Q1 conducting; The collector voltage of triode Q1 becomes low level, triode Q2 conducting, and the cathode voltage of capacitor C 1 is become the voltage of VCC by lower voltage; The cathode voltage of capacitor C 1 is with respect to control ground at this moment; To be to approach 2 times VCC, this VCC voltage of 2 times have produced the big electric current that provides coil to start through the coil of relay K 1; And need not to extract the output of big electric current from power supply, reduced the pressure of power supply.Capacitor C 1 electric energy stored will be consumed by the coil of relay K 1 very soon, and the current potential at capacitor C 1 two ends will be tending towards equal, and the electric current of keeping of the coil of relay K 1 is provided by VCC.
Use contrast: like the relay coil of specified 24V, coil resistance is assumed to 100 ohm, and VCC is set in 24V, and the power consumption of keeping of coil will be 5.76W, and also need provide a big electric current to inject in actuating of relay moment; If VCC is set in 16V, the holding power of relay coil is 2.56W like this, this shows, coil is kept power consumption and reduced significantly.Further reduce the pressure of power supply, improve system effectiveness.
