Abstract
The utility model discloses a control circuit for energy -conserving coil of electromagnetic type switch, its characterized in that: control circuit include that drive power supply sends voltage stabilizing circuit and voltage detection circuit into the singlechip respectively and handles, singlechip output pwm signal PWM passes through the solenoid that drive circuit inserted energy -conserving coil. Since the above structure is adopted, the utility model discloses a solenoid's circular telegram among the pulsewidth modulation PWM technical control electromagnetic type switch, when saving the enameled wire quantity, the coil energy consumption during the greatly reduced actuation again. Improve the reliability of control.
Description
Technical field
The utility model relates to controlled electromagnetic switch, particularly a kind of control circuit for controlled electromagnetic switch Energy-saving coil.
Background technology
At present the method for designing of controlled electromagnetic switch Energy-saving coil be employing two groups of coils, be respectively used to adhesive and maintenance.This method, except consuming except enamelled wire more, also makes design parameter complicated, not easily ensures reliability and the consistency of product.There is power consumption large, the shortcoming such as to generate heat large.
For the problems referred to above, provide a kind of novel control circuit to carry out Energy Saving Control to controlled electromagnetic switch, improving the reliability controlled is the problem that prior art needs to solve.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of control circuit for controlled electromagnetic switch Energy-saving coil, carries out Energy Saving Control to controlled electromagnetic switch, improves the reliability controlled.
For achieving the above object, the technical solution of the utility model is, for a control circuit for controlled electromagnetic switch Energy-saving coil, it is characterized in that: described control circuit comprises driving power and voltage stabilizing circuit and voltage detecting circuit feeding single-chip microcomputer processed respectively; Single-chip microcomputer output pulse width modulation signal PWM is by the solenoid of drive circuit access switch.
Described control circuit is at the initial stage of adhesive, Single-chip Controlling drive circuit exports big current and controls the larger electromagnetic force of solenoid output, make moving contact quick pick-up, after the adhesive of contact, single-chip microcomputer dynamically changes the output of PWM according to input voltage, reduces the power output of drive circuit to maintain contact adhesive.
Under Micro Controller Unit (MCU) driving controls, the power of contact adhesive maintenance stage solenoid consumption is 10% of the adhesive initial stage.
Described single-chip microcomputer is time delay output pulse width modulation signal PWM after driving power power-off being detected, avoids driving power instant cut-off.
A kind of control circuit for controlled electromagnetic switch Energy-saving coil, owing to adopting above-mentioned structure, the utility model adopts the energising of solenoid in pulse-width modulation PWM technical controlling controlled electromagnetic switch, while saving enamelled wire consumption, greatly reduces again the coil energy consumption during adhesive.Improve the reliability controlled.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is a kind of control circuit structural representation for controlled electromagnetic switch Energy-saving coil of the utility model;
In FIG, 1, driving power; 2, voltage stabilizing circuit; 3, input voltage detection circuit; 4, single-chip microcomputer; 5, drive circuit; 6, solenoid.
Embodiment
As shown in Figure 1, the utility model comprises driving power 1 and respectively voltage stabilizing circuit 2 and input voltage detection circuit 3 is sent into single-chip microcomputer 4 and process; Single-chip microcomputer 4 output pulse width modulation signal PWM accesses 6 of Energy-saving coil by drive circuit 5.
Control circuit is at the initial stage of adhesive, single-chip microcomputer 4 controls drive circuit 5 and exports the contact adhesive of big current control solenoid 6, after solenoid 6 contact adhesive, single-chip microcomputer 4 dynamically changes the output of PWM according to input voltage, reduces the power output of drive circuit 5 to maintain adhesive.The power output that solenoid 6 contact single-chip microcomputer 4 after adhesive controls drive circuit 5 is 10% of the adhesive initial stage.
Except above basic function; can according to the instructions for use of user; make electromagnetic power source switch in wider voltage range; accurately can judge again whether the fluctuation of voltage has surmounted scope and taked corresponding protection act or alarm, and traditional method is difficult to the consistency ensureing product.For another example deferred action when moment powers on again after can realizing electric voltage exception power-off, avoids the harm to electrical system.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various improvement that technical solutions of the utility model are carried out; or directly apply to other occasion, all within protection range of the present utility model without improving.
