Brief description of the drawings
Multiple embodiments of the invention are expanded on further with following explanation with reference to the accompanying drawings.Wherein：
Fig. 1 shows a kind of control circuit of prior art；
Fig. 2 shows a kind of implementation methods of the control circuit for being used for two contactors of the invention；And
Fig. 3 shows a kind of particular embodiment of control circuit of the invention.
Specific embodiment
A kind of control circuit 30 of prior art is shown in Fig. 1.This is used to control two control circuits 30 of contactor,
Control coil 50 is wherein only respectively illustrated, is connected with voltage source 60 by the first and second connection ends 11,12, the voltage
Source 60 powers for control circuit 30, but also provides the electric current for controlling these contactors controlled by the control circuit 30.This
The control coil 50 of a little contactors is connected with the control circuit 30 by the first output end 15 and two the second output ends 16.The control
Circuit processed 30 has a first switch 41 and two second switches 42, and the wherein first switch 41 is connected to the of voltage source 60
Between first output end 15 of one electrode and control circuit 30, and two second switches 42 are connected to the of voltage source 60
Between corresponding second output end 16 of two electrodes and control circuit 30, therefore in corresponding electrical connection 8, it is respectively at multiple
One in output end 16 is and the second connection end 12 between.If this three switches 41,42 are closed at, then the control coil
50 are directly connected with voltage source 60 and begin to flow through maximum current, and the electric current is sufficiently large, to cause the contactor of control coil 50
Can adhesive so that these contactors are transferred to conducting state.
In addition the control circuit 30 has voltage holding unit 10, and the voltage holding unit 10 is equally supplied by the voltage source 60
Electricity.The voltage holding unit 10 causes the flowing for keeping electric current, holding stage of the holding electric current after the adhesive stage is followed closely
For keeping these contactors to close.Because being flowed unlike needing to overcome the mass inertia of motor contactor in the adhesive stage herein
The more low current of control coil 50 is crossed just to keep these contactors enough in closure state, therefore, it is possible to advantageously save work(
Rate.Therefore (and activation voltage holding unit 10 when necessary) is again off in the stage of holding first switch 41, so that the control
Coil processed 50 is only flowed through by holding electric current.The holding electric current flows through diode 45 herein, and the diode 45 is connected to voltage guarantor
Hold between unit 10 and multiple control coils 50 and effect is, prevent the electric current stream in the output end of voltage holding unit 10
It is dynamic.
Fly-wheel diode 46 is extraly set in Fig. 1, and it is in the case of keeping electric current to disconnect for control coil 50
The electric current of flowing provides no-load current path.Thus the separation phase starts, i.e., second switch 42 also disconnects and another when necessary
Outer deactivation voltage holding unit 10.Because the control coil 50 flows through the change of its electric current due to its inductive obstacle,
Its from supply voltage separation after its also produce electric current flowing, now due to series circuit, the electric current flowing connect fly-wheel diode
46 and diode 45.Because the necessary conducting electric current in the second connection end of control coil 50, accordingly generates high herein
Negative voltage, the negative voltage causes punch through the Zener diode as terminal voltage element 47.Electric current in the control coil 50 is quick
Reduce, so that the magnetic field of control coil 50 is also reduced and corresponding contactor departs from, thus these contactors are disconnected.
