Accompanying drawing explanation
Fig. 1 is the circuit diagram of anti-interference Electricity-limiting protector control circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of anti-interference Electricity-limiting protector control circuit, comprise resistance R1, diode D1, relay J and inductance L, one end of described resistance R1 connects electric capacity C1, load A and 220V line voltage, the other end of resistance R1 connects the other end of electric capacity C1, the anode of diode D1 and the negative electrode of diode D5, the anode of diode D5 connects electric capacity C2, the negative electrode of diode D3, the anode of diode D4, resistance R5, the other end of 220V line voltage and inductance L, the negative electrode contact resistance R2 of diode D1, the other end of electric capacity C2 and the collector electrode of triode V2, the other end contact resistance R3 of resistance R2 and the collector electrode of triode V1, the base stage of the other end connecting triode V2 of resistance R3, the base stage of triode V1 connects a stiff end of electric capacity C4 and potentiometer RP1, the sliding end of potentiometer RP1 connects electric capacity C3, another stiff end of potentiometer RP1 and the negative electrode of diode D2, the anode of diode D2 connects the other end of inductance L and the contact J-1 of relay J, the other end of the contact J-1 of relay J connects the other end of load A, the other end of the emitter contact resistance R5 of triode V1, the emitter contact resistance R4 of triode V2, the negative electrode of diode D4 and the other end of relay J, the other end of resistance R4 connects the anode of diode D3.
Relay J is normally opened contact relay.
Operation principle of the present utility model is: 220V alternating current, through electric capacity C1 step-down, provides low-voltage dc voltage to circuit after diode D1 and diode D5 rectification and electric capacity C2 filtering.When load A unloaded or less time, triode V1 only carries, V2 conducting, performs relay J and obtains electric closed, load A normal power supply.When load A excess load, the induced voltage at sampling inductance L two ends increases, after diode D2, C3, RP1 and C4 detection filter, make V1 saturation conduction, and V2 ends, and relay J power down discharges, load power down.At this moment because L both end voltage is zero, the reverse-biased cut-off of diode D2 is high-impedance state, and the electric charge of C3, C4 slowly discharges through RP1 and V1, forms time delay, and after a few minutes, V1 only carries, and V2 is conducting again, and relay J is adhesive again, circuit automatic recovery of power supply.If the extra load of user is not yet removed, circuit will repeat said process, until the overload load restoration of user is normal.Starting current due to the household electrical appliance such as refrigerator and colour TV is 3-5 times of operating current, this will exceed the limit value of controller, therefore form heavy current impact circuit by RP1 and C4 to be used for preventing circuit erroneous action, circuit adopts transless buck configuration, reduce circuit volume, and be provided with heavy current and impact module, starting current can be prevented, false triggering that power network fluctuation causes, therefore there is the advantage of easy to use, strong interference immunity and stable performance.
