Description of drawings
Fig. 1 is the circuit diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
With reference to Fig. 1, a kind of automatic electric limiting controller of the present utility model, it comprises power circuit, sample circuit, monostable flipflop and relay K 1, described power circuit is by decompression capacitor C1, bleeder resistance R0, rectifier diode VD1, voltage stabilizing didoe VS1 and filter capacitor C2 form, described sample circuit is by current transformer TA, rectifier diode VD2, filter capacitor C3, variable resistor RP1 and resistance R 1 are formed, described monostable flipflop is by transistor V, 555 time-base integrated circuit IC and peripheral resistance (R2, R3), variable resistor RP2, electric capacity (C4, C5), light-emitting diode VL and diode VD3 form, and described relay K 1 is selected the direct current relay of model JRX-11 for use.
VD1, VD2 and VD3 all select 1N4001 type silicon rectifier diode for use, VS1 selects the 1N4742 type voltage stabilizing didoe of " 1W; 12V " for use, VS2 selects the 1N5245 type voltage stabilizing didoe of " 0.5W; 15V " for use, V selects the silicon NPN transistor of model S9013 for use, it is that 0.68～1 μ F withstand voltage is the above electric capacity of the dacron of 400V that C1 selects capacity for use, C2, it is the electrolytic capacitor of 25V that C3 and C4 select withstand voltage for use, C5 selects dacron terylene condenser for use, the winding of current transformer TA is around 5 circles, secondary winding is around 1000 circles, but resistance R 0 value 680k, R1 and R2 be value 1k respectively, 18k, R3 value 2k.
With reference to Fig. 1, the course of work of the present utility model: alternating current 220V voltage produces the direct voltage about 12V after C1 step-down, VD1 rectification, VS1 voltage stabilizing and C2 filtering, supply with transistor V and 555 time-base integrated circuit IC.
When user's power consumption did not transfinite, the induced voltage at the secondary winding two ends of TA was lower, and V ends, and 2 pin of IC are high level, 3 pin output low levels, and the normally closed interlock K1 of relay K 1 connects, to user's normal power supply.During when user's power consumption increase and above former set point, induced voltage on the TA secondary winding will increase, and make the V conducting, and 2 pin of IC become low level, monostable flipflop becomes transient state by stable state, 3 pin of IC become high level by low level, make relay K 1 adhesive, and its normally closed interlock K1 disconnects, cut off user's power supply, simultaneously, light-emitting diode VL also lights, and indication user's power consumption exceeds standard.
When monostable flipflop overturns in IC, the discharge tube conducting of 7 pin inside, making 6 pin of IC and 7 pin is low level ,+12V voltage to capacitor C4 charging, raises the 6 pin voltages of IC through RP2 gradually.When this pin voltage rises to about 8V) time, the monostable flipflop upset of IC inside becomes stable state by transient state, and 3 pin of IC become low level by high level, and relay K 1 is discharged, and recover the user is powered.If this moment, user's power consumption still transfinited, then the automatic electric limiting controller will repeat said process.Regulate the resistance of RP1, can set user's consumption limit amount, regulate the resistance of RP2, can change the time of delay of monostable circuit.
