Circuit control principle figure explanation：
Signal X：(alternating current fire wire 220V series connection 100K resistance) high level (having 220V voltage) is provided to represent by electric energy meter
There is expense, low level (no 220V voltage) represents arrearage.
Feedback signal F:Connect chopper outfan (series resistance 100K), high level represents breaker closing, low level table
Show tripping operation.
Breaker closing：When it is that holding wire X has 220V alternating voltage that electric energy meter has expense, this electric current X through full-bridge U2 rectification,
Its positive electrical flows through diode D3, then through adjustable resistance and electric capacity R3 time delay, then through Zener diode pressure limiting, then through diode
D1, optocoupler controllable silicon OC, diode D4, audion G1 conducting, return to the negative pole of full-bridge U1.Now, audion G2 conducting and three
Pole pipe G3 is ended.Meanwhile, alternating current power supply A, N, through electric capacity C1 current limliting, full-bridge U1 rectification, DW1 and C2 voltage regulation filtering, provides small machine
M rotates and closes a floodgate.When in-place closing, little switch K closure, and so that audion G1 cut-off, optocoupler controllable silicon OC is turned off and small machine
Stall.Now, umbrella shape drivewheel and fan-shaped driven pulley depart from, and chopper can be with manual operation.
Circuit breaker trip：When electric energy meter no takes that i.e. holding wire X does not have electricity, audion G1 is by, audion G2 cut-off, three poles
Pipe G3 conducting (now in "on" position, feedback signal F has electricity, provides the base current of audion G3), meanwhile, electric capacity C3 is put
Electricity, and so that optocoupler controllable silicon OC is turned on, (electric capacity C2 gives optocoupler controllable silicon afterflow again through D2 and R1) power supply A, N limits through electric capacity C1
Stream, through stabilivolt DW1 and electric capacity C2 voltage regulation filtering, a road electricity provides small machine to be rotated further, another road electricity through diode D2 and
Resistance R1 is to optocoupler controllable silicon OC afterflow.This electric current passes through diode D5, audion G3 again, returns to full-bridge U1.When motor rotates
When, the dropout pin of the slide block shake-up chopper of synchronous axial system, circuit breaker trip, and the outfan no current of chopper, that is, instead
Feedback signal F is no electric, and that is, audion G3 does not have base current and by meanwhile, optocoupler controllable silicon OC is by small machine stall.Now,
Poke rod heads on dropout pin, that is, reach the purpose that arrearage can not be closed a floodgate.
If electric energy meter has expense to repeat above-mentioned circulation.
At present, the control circuit taking control chopper reclosing product is all using Switching Power Supply, single-chip microcomputer, permanent magnet, Hall
Element controls, and therefore, control circuit is complicated, and diamagnetic interference is poor, relatively costly.On the circuit that this utility model provides does not exist
State defect.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement and modification, above-mentioned vacation can also be made
If these improve and modification also should be regarded as protection domain of the present utility model.
