The operation principle of embodiment is power supply electricity after poly phase rectification, under being controlled by power control circuit for the bus power supply
Road is converted into system power supply, uses for each electronic circuit.
Power control circuit has following functions: 1. when micro-control unit system 6 does not control to it, in bus power supply again
There is the function of time delayed turn-off during upper electricity；2., when bus power supply has electricity, when control level is for low level, can remain off
State；When control level is high level, conducting state can be maintained.
External control signal passes through sample circuit, and micro-control unit system 6 provides power supply and signal.
Micro-control unit system 6 passes through motor-drive circuit controlled motor action；Micro-control unit system 6 is examined by position
Slowdown monitoring circuit judges the positions such as the on/off switch of electricity behaviour
For switching when processing procedure be: when system power supply re-powers, control circuit first turn on after time delayed turn-off,
Now micro-control unit system starts, are turned on by power control circuit, and power supply is started working, and detect external control signal
And current electric operating state, if electric operating state position meets external control signal requirement, micro-control unit system passes through power supply control
By power remove, micro-control unit system power failure, power control circuit remains off state to circuit processed, and now power consumption is ua level；
If not meeting external control signal requirement, micro-control unit system is passed through controlled motor and electricity behaviour is turned to correspondence position, so
Micro-control unit system, again by power remove, enters holding state afterwards.
When system power supply has electricity but electricity behaviour is in holding state, now external control signal, will carry to there being electricity from no electricity
, to micro-control unit system, micro-control unit system identification is system electrification or external control signal change for power supply source and signal
If system power supply has voltage afterwards, it is system electrification, be otherwise then electricity in control signal, control electric power starting, then controlled motor
Electricity behaviour is turned to after correspondence position, then power cutoff enters holding state；When external control power supply is when having electricity to no electricity, storage
The energy deposited can maintain micro-control unit system work certain time, and micro-control unit system determines control signal within this time
State, and power-on conducting, electricity behaviour are turned to behind relevant position, then power cutoff, enter holding state, and now system is
No electric eventually, until bus power supply or external control signal activation.
For in electricity behaviour's making process, process in the case of bus power supply power-fail: when energy-storage travelling wave tube energy is not enough,
Micro-control unit circuit system passes through charge-discharge control circuit and charges to energy-storage travelling wave tube, stops after energy-storage travelling wave tube stores enough energy
Only charge.
When electricity behaviour needs action, power circuit and energy-storage travelling wave tube are powered to system power supply simultaneously, micro-control unit system
By motor-drive circuit controlled motor, motor status are determined by position detecting circuit, determined by sample circuit female simultaneously
Line power supply status, if bus power supply is normal during action, when motor action is to specified location, motor stalls, energy storage unit
Part discharge circuit cuts out.
When abnormal conditions occur: when i.e. during motor action, bus power supply falls, single-chip microcomputer determines that bus power supply falls,
By motor-drive circuit, motor is stopped, reduce the consumption of currently stored energy, then motor is turned to a certain finger
Positioning postpones, and motor is stopped, and energy-storage travelling wave tube discharge circuit cuts out.
A kind of electric operating mechanism of circuit-breaker circuit that this utility model provides, can reduce motor-operating mechanism need not
Power consumption during work, and meet output power of motor increase using electron stored energy mode and do not change the purpose of chopper volume.
