Description
Technical field
The present invention relates to a kind of according to the calutron as described in the preamble of the first Patent right requirement and for transporting
The method of this calutron of row.This device provides electric energy by the electric controller of upper level, wherein also describing this upper level herein
Electric controller, but it is not a part of the device of the invention.
Background technique
The piston pump of the linear action of solenoid-operated proportional magnet, proportioning valve and electromagnetism operation is supplied advantageous by electric controller
Electric energy, the electric controller preferably adjust the level of effective supply voltage by pulse width modulation.Here, the electric controller
Comprising electric switch, opened and closed by PWM frequency.The level of the effective voltage is then generated by duty ratio.
If PWM frequency selection will not or only penetrate in the reasonable scope enough to height, the pulse of pulse width modulation
The function of provided device, because common electromagnet has quite high inductance.
Routine electric controller for this purpose has so-called unloaded diode, to protect so-called electric switch,
The zero load diode continues flow through the electric current of electromagnet after opening the electric switch, but does not have working voltage.Without zero load
Diode will lead to the high open circuit voltage of electric switch, this may destroy the electric switch.Two pole of zero load in electric controller
Pipe causes two disadvantages:
Electromagnet very slowly can only powerlessly switch, because decay time is the electricity by inductance and with unloaded diode
Caused by extremely low resistance in road.
In the case where not intervening electric controller, decay time is unaffected.

Here, electric switch is controlled by the voltage of the second input end of circuit at least by first diode.
Second input terminal of electric switch is connected with the second output terminal of the controller of upper level.
When electronic circuit breaker is opened, the electric current of electromagnetic coil flows through electric braking device, and electric braking device makes electric current and pre-
Fixed resistance and/or scheduled brake voltage on the contrary, wherein after short times by the electric current of electromagnetic coil (with it is this
The decay time of brake voltage is compared) stop.
Electric braking device is preferably by the in series of Z diode and resistance.Z diode can be herein it is unidirectional, also can
It is enough two-way.
Equally, electric switch further preferably includes delayer, and delayer and first diode influence electronic circuit breaker in parallel.
Here, delayer includes at least one capacitor and resistance.Capacitor and resistance have determined the delay time of delayer.
Here, capacitor is preferably connected with the first input end of electric switch, so as to by the voltage support applied there.
Advantageously, first diode is closed electronic circuit breaker in its conduction, because the voltage at second output terminal fills
Divide the voltage of the first output lower than controller.
It is closed electric switch in upper level controller, it is also preferred that carrying out this point.If the first of controller is defeated
Voltage in outlet can overcome the resistance of semiconductor involved in resistance and closure electronic circuit breaker during signal path
Power-off pressure, then the voltage in the second output terminal of controller is sufficiently below the voltage on the first output end of controller.
It is further advantageous that if the voltage of the second output terminal of controller sufficiently above controller first output
Voltage, then delayer is in scheduled delay time TvElectronic circuit breaker is opened later.
Open electric switch in upper level controller, it is also preferred that carrying out this point.
If the voltage on the first input end of circuit can overcome the resistance and opening electronics during signal path
The blocking voltage of semiconductor involved in breaker, then the voltage on the second input terminal of circuit is then sufficiently above the first of circuit
Voltage on output end.
Electric switch is preferably field effect transistor, has very small resistance in closed state.If field-effect
The resistance of transistor is less than the resistance of electromagnetic coil, then the resistance of the field effect transistor is very small.
In the first advantageous embodiment, electric switch is inseparably connect with electromagnetic coil, such as by common
Plastics extrusion encapsulation part.
In the second advantageous embodiment, electric switch is connect by third plug-in connector with electromagnetic coil, wherein
Electric switch setting is in centre plug shell.
Cable is for example connected by the first plug-in connector with controller, and the second plug-in connector by cable with electrically open
It closes and is connected.
In order to run by calutron of the invention, electric controller produces the arteries and veins of supply voltage under first method of operation
Width modulated is rushed, has and is less than preset limit frequency FGFrequency.
The limiting frequency is substantially from delay time TvIt calculates, wherein FG=k/ (2*p*Tv), wherein k, which is used as, is simulating or is trying
Test the correction factor of middle acquisition.
In this case, delayer will be conducted in the pulse positive voltage of its input end to electronic circuit breaker, depending on
Phase opens electronic circuit breaker, but reduces turn-on time.
If the voltage in second output terminal is negative enough relative to the voltage on the first output end, diode is forthwith
It is again switched off electronic circuit breaker.
If voltage can overcome resistance during signal path and open semiconductor involved in electronic circuit breaker
Blocking voltage, then voltage is negative enough.
Under second method of operation, electric controller produces the pulse width modulation of supply voltage, has greater than predetermined
Limiting frequency FGFrequency, and have greater than preset limit duty ratio duty ratio, as a result, due to detection interval in
Positive voltage pulse be shorter than delay time Tv, therefore delayer will not be inputted the positive voltage pulse at end and pass to electronic broken circuit
Device, and breaker of electronic circuit will not be opened.
Using:
Related electromagnet is quickly shut off if necessary, then is used to control ratio magnet, electricity in the device of the invention
The piston pump of magnetic proportioning valve and electromagnetism operation.
