Circuit control principle figure illustrates:
Signal X: provided the expression of (alternating current fire wire 220V connect 100K resistance) high level (having 220V voltage) by electric energy meter
Having expense, low level (without 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 electric energy meter has an expense i.e. holding wire X has 220V alternating voltage, 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
