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, current detection circuit and control circuit.The elementary winding of power transformer T inserts civil power, secondary winding connects the input of rectifier bridge heap UR1,1 pin of the output termination three terminal integrated voltage stabilizer IC1 of UR1, filter capacitor C1 is connected in parallel on the output of UR1, the 2 pin ground connection of IC1, output 3 pin a road behind the series circuit that R1 and VL1 form ground connection, another road connect 1 pin of switch integrated circuit IC2, power transformer T, rectifier bridge heap UR1, filter capacitor C1, three terminal integrated voltage stabilizer IC1, resistance R 1 and light-emitting diode VL1 form power circuit.
The elementary winding of current transformer TA inserts civil power, and secondary winding connects the input of rectifier bridge heap UR2, the output shunt capacitance C2 of UR2 and potentiometer RP, and current transformer TA, rectifier bridge heap UR2, capacitor C2 and potentiometer RP form current detection circuit.
The centre cap of potentiometer RP connects 5 pin of switch integrated circuit IC2, relay K 1 in parallel and diode VD between 2 pin of IC2 and the ground, the series circuit that resistance R 2 and light-emitting diode VL2 form is parallel between 2 pin and ground of IC2,3 pin link to each other with 2 pin, 4 pin ground connection, switch integrated circuit IC2, relay K 1, diode VD, resistance R 2 and light-emitting diode VL2 form control circuit.
Three terminal integrated voltage stabilizer IC1 model is LM7824, the model of switch integrated circuit IC2 is TWH8778, power transformer T selects the power transformer of 5W, 12V for use, and winding technique 6～10 circles of current transformer TA, secondary winding coiling 100 circles, K1 are selected the two contact relays of JZX-2F type for use.
With reference to Fig. 1, the course of work of the present utility model: alternating current 220V voltage is after T step-down, UR1 rectification, C1 filtering and IC1 voltage stabilizing, and generation+12V voltage as the operating voltage of IC2, is also lighted power supply indication light-emitting diode VL1 simultaneously.User's household electrical appliance insert civil power through the normally closed interlock of current transformer, when user's power consumption does not surpass the electric current predetermined value, induced voltage signal on the TA secondary winding a little less than, dc voltage value on 5 pin through adding to IC2 after the UR2 rectification is lower, IC2 does not work, relay K 1 can not adhesive, and its normally closed interlock K1-1 and K1-2 connect, and user's household electrical appliance can operate as normal.When the user inserts high-power electric appliance (for example Electric stove etc.) and power consumption is surpassed set current value, induced voltage on the TA secondary winding will raise, make the 5 pin voltage increases of IC2, IC2 conducting work, its 2 pin becomes high level by low level, makes relay K 1 adhesive, its normally closed interlock K1-1 and K1-2 disconnect, cut off user's power supply, light-emitting diode VL2 lights simultaneously, and the indication user is excess load.
The resistance value of regulator potentiometer RP can change the current limit value of supply load.During adjustment, the household electrical appliance energized that elder generation uses the user always, regulator potentiometer RP is failure to actuate relay K 1 then, inserts the Electric stove (or the identical electrical appliance of power) of a 2KW again, regulates RP, and the K1 action is got final product.
