Abstract
The utility model relates to an energy-storing energy-saving circuit for DC electromagnetic action devices. A high-voltage generating circuit is electrically connected to a resistor with large resistance after being output by a single current device (such as a diode) to charge a capacitor; a low-voltage generating circuit is electrically connected to the capacitor after being output by a single current device (such as a diode); meanwhile, the voltage of the capacitor is not too high by a capacitor voltage limiting circuit, the volume value of the capacitor and the charging voltage of the capacitor need to satisfy the voltage and the current which are needed by the DC electromagnetic action devices when in action, and the voltage of the low-voltage generating circuit in the circuit after being output by the diode needs to properly larger than the voltage value for keeping the DC electromagnetic action devices in an action state. In this way, the energy-storing energy-saving circuit can drive the DC electromagnetic action devices. The utility model can be widely used in circuits using the DC electromagnetic action devices, and has the advantages of that the electricity is saved, and the DC electromagnetic action devices (relays, electromagnetic valves and the like) with many loads can be driven by small power transformers.
Description
Technical field
The utility model relates to a kind of driving of DC magnetic motion device, belongs to the electrotechnical, electronic aspect.In circuit design, belong to the design of driving power.This technology can be widely used in the driving of DC magnetic motion device (relay, electromagnetically operated valve etc.).
Background technology
At present, in circuit design, generally use rated voltage to give DC magnetic motion device (relay, electromagnetically operated valve etc.) power supply, in sort circuit, DC magnetic motion device (relay, electromagnetically operated valve etc.) power consumption is a lot, and the life-span is shorter, and the every of power supply had relatively high expectations, and cost is also high.
Yet it is exactly after it starts that DC magnetic motion device (relay, electromagnetically operated valve etc.) all has individual characteristics, only need just can keep its work than the little a lot of voltage of its rated operational voltage value.People are according to these characteristics, also the someone improves the energy saving driving circuit of having designed capacitance energy storage type, as the low energy consumption relay drive circuit (patent No.: Fig. 7-Figure 10 ZL200520055762.8), but sort circuit is higher to the power supply stability requirement, the resistance of the resistance that is used to charge can not be too big, and, after the starting of electromagnetism motion device, the resistance that is used to charge has become the resistance of step-down, and resistance need consume a lot of electric energy.To the stability requirement height of power supply, just need with bigger transformer or the complicated Switching Power Supply power supply of use.
Summary of the invention
In order to reduce cost, in circuit design, neither use complicated switching power circuit, overcome the shortcoming that in linear power supply, needs to use the big transformer of power again, the utility model can only be used the power smaller transformer, and under the lower situation of line voltage, the DC magnetic motion device that driving power that can be stable is bigger (relay, electromagnetically operated valve etc.) still.
The technical scheme that its technical problem that solves the utility model adopts is: after exporting by unidirectional current device (as diode) with a circuit for producing high voltage, being electrically connected the bigger resistance of a resistance charges to electric capacity, produce with a low-voltage and to be electrically connected on the electric capacity after circuit is exported by unidirectional current device (as diode), be unlikely too high with an electric capacity pressure limiting circuit by the voltage of electric capacity simultaneously, the parameter of suitable selecting circuit, capability value as electric capacity, the voltage limiting value of electric capacity etc., the voltage and current that the starting that makes it satisfy DC magnetic motion device is required, low-voltage in the circuit produces the voltage of circuit after exporting by diode, want suitable to the magnitude of voltage that keeps the DC magnetic motion device operate condition, the output voltage circuit that obtains so just can stable being used to drive DC magnetic motion device work.
The technical solution of the utility model is to use diode and big resistance to charge to electric capacity, and the power requirement to circuit for producing high voltage just can reduce like this, just can accomplish with little transformer, and charging resistor power consumption simultaneously also greatly reduces.Low-voltage generation circuit preferably passes through voltage stabilizing.The electric capacity pressure limiting circuit also can be made adjustable, is convenient to actual use flexibly.The voltage of charging capacitor can be suitably greater than the rated voltage of electromagnetism motion device, and when the electromagnetism motion device moved, electric capacity discharged rapidly, because overvoltage is temporary, so and be not easy to burn solenoid.A shortcoming of circuit is, must be filled with enough when electric at electric capacity, and circuit could normal starting electromagnetism motion device, can give circuit an additional again capacitance voltage testing circuit, when allowing the electric capacity full charge, just allows to start the electromagnetism motion device.
The beneficial effects of the utility model are, saves energy, can be under the situation of not using complicated Switching Power Supply, only with the less power transformer stable more DC magnetic motion device (relay, electromagnetically operated valve etc.) of driving load of energy just, saved cost, reduced product weight, reduced the circuit energy consumption, and the enforcement of circuit is also very simple.
