1) in positive reason electricity consumption situation, intelligent electric meter has expense and breaker closing, and the 4th pin level of single-chip microcomputer is low, and the 6th pin is also low, and circuit for controlling motor and dropout control circuit are neither worked.
2) when arrearage situation occurs, the 6th pin of single-chip microcomputer remains lowly, is first that variation has occurred for CR end, and level has become 0V from 220V saltus step, and the 4th pin level be height from low saltus step.Single-chip microcomputer detects that the control signal of intelligent electric meter disappears, and the 6th pin or low level shows that single-chip microcomputer has judged arrearage of user, but handle is also in "on" position, thus time delay after two seconds single-chip microcomputer to the 1st pin output high level pulse.In the time that the 1st pin is set to high level, the SCR control utmost point also has high level, so controllable silicon is switched on, shunt release moves, circuit breaker trip.Handle becomes gate-dividing state from "on" position, and single-chip microcomputer the 6th pin is set to high level, shows that handle separates, isolating switch is separating brake, single-chip microcomputer stops driving the 1st pin, otherwise the 1st pin can be exported continuous pulse signal, uprises until circuit breaker trip is the 6th pin level.Because this power supply provides the direct supply of half-wave rectification, so controllable silicon Q2 can be turned off in the time of voltage over zero.Now the electric weight of super capacitor C4 does not consume.
3) after user continues to pay dues, now control signal 220V voltage signal is set up, single-chip microcomputer the 4th pin is low from high saltus step, but handle is still still high level in gate-dividing state event the 6th pin, and single-chip microcomputer learns that user continues to pay dues after identifying this state, but switch is still at gate-dividing state, single-chip microcomputer is to the 3rd pin output high level, metal-oxide-semiconductor Q3 is switched on, and circuit for controlling motor starts drive motor Z2, and motor Z2 drives breaker mechanism to realize automatic switching-in function.When breaker closing put in place handle be also rotated in place after single-chip microcomputer the 6th pin be set to low level, single-chip microcomputer stops driving the 3rd pin.The power supply that motor closes a floodgate is provided by the electric weight of super capacitor C4.
Through above-mentioned a series of logic judgements, single-chip microcomputer has been realized the Based Intelligent Control to miniature circuit breaker by this circuit.The problem of closing by hand after having solved current prepayment small-sized circuit breaker and continuing to pay dues.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
