As shown in Figure 1 and Figure 2, a kind of backup type contactor maintenance adaptively anti-shake electric installation, including storage capacitor
C, magnetic red switching switch K1, standby direct current supply module DC and controller W.
After storage capacitor C positive pole and negative pole are connected with external ac power source AC positive pole and negative pole, it can be filled
Electricity.
Magnetic red switching switch K1 has the main contacts a being connected with contactor coil KM first end and external ac power source
The normally-closed contact b and be connected with the positive pole of storage capacitor C positive pole and standby direct current supply module DC that AC positive pole connects
Normally opened contact c, contactor coil KM the second end and external ac power source AC negative pole, storage capacitor C negative pole and after
Standby direct current supply module DC negative pole connection, controller W switch switch K1 with magnetic red and are connected.
Specifically, the utility model is also provided with charging resistor R, charging diode D1 and discharge diode D2, charging
Resistance R one end is connected with charging diode D1 positive pole, and the other end is used to be connected with external ac power source AC positive pole, charges
Diode D1 negative pole is connected with storage capacitor C positive pole, and discharge diode D2 positive pole is connected with storage capacitor C positive pole,
The normally opened contact c that negative pole switches switch K1 with magnetic red is connected.
When storage capacitor C charges, its charged diode D1 and charging resistor R and external ac power source AC positive pole
Connection, current limliting and protection are carried out, in electric discharge, repid discharge path is provided by discharge diode D2.
Specifically, the utility model is also provided with anti-reverse diode D3 and sustained diode 4, anti-reverse diode
D3 positive pole is connected with standby direct current supply module DC positive pole, and the normally opened contact c that negative pole switches switch K1 with magnetic red is connected, and is prevented
Only reversely charging, the positive pole of sustained diode 4 are connected with contactor coil KM the second end, and negative pole switches the normal of switch K1 with magnetic red
Contact c connections are opened, afterflow effect are played, with the back-emf voltage of limiting coil, protection circuit.
The utility model is using magnetic red switching switch, long lifespan, it is not easy to damage.
Preferably, magnetic red switching switch K1 is using high-pressure mercury magnetic red switching switch, quick action, operating time scope
100 μ s to 300 μ s, switching high pressure reach upper kilovolt, and mercury contact has big contactor ability, unlike common relay is easy
Adhesion is burnt out, this feature ensure that the long-life of switch two-way contact.
In order to set the anti-shake electric time, the utility model is also provided with toggle switch K2, toggle switch K2 and controller W company
Connect, and toggle switch K2 has two-position switch, first toggle switch represents the second, and second toggle switch represents 0.1 second, its
Time setting range is the 0-9.9 seconds.If two toggle switch are arranged to 00, then it represents that anti-shake Electricity Functional exits.
The utility model can be debugged, the utility model as a result of toggle switch in the case of no electricity
Realize and debugged without electricity, without considering installation site, mitigate debugging difficulty, debug time and debugging cost significantly, be particularly suitable for taking out
Chest of drawers.
In use, contactor coil KM is powered by external ac power source AC.
In power supply process, external ac power source AC charges for storage capacitor C.
After controller W is received and shaken electric signal, anti-shake electric treatment is carried out：
1st, according to the default anti-shake electric time, timing is carried out.
2nd, magnetic red switching switch K1 is controlled by controller W, magnetic red switching switch K1 main contacts a is cut from normally-closed contact b
Shift to normally opened contact c adhesives, from standby direct current supply module DC to contactor coil KM power：
Now, contactor coil KM is given in storage capacitor C energy abrupt release, and contactor is kept with strong DC pulse
Contact adhesive, after electric energy release, standby direct current supply module DC is provided to contactor coil and is kept voltage naturally.
It is pointed out that the magnetic red switching switch K1 initial adhesive of normally-closed contact b and main contacts a, from external communication electricity
Source AC obtain it is electric after, under controller W control, normally-closed contact b and main contacts a still adhesives, when controller W receives rolling electric signal
Afterwards, controller W controls main contacts a and normally opened contact c adhesives, if internal fault or damage, magnetic occur for the utility model device
Spring switching switch K1 can not obtain electric, and because b be normally-closed contact, c is normally opened contact, now, main tactile without controller W control
Point a will switch as normally-closed contact b from normally opened contact c, therefore contactor can be made to automatically switch to outside friendship on hardware mode
Flow power supply AC power supplies.
If the 3rd, recover in anti-shake electric time inside and outside voltage, the anti-shake electric time terminate (no matter external voltage whether recover) or
When person receives anti-shake electric exit instruction, then magnetic red switching switch K1 is controlled by controller W, touch magnetic red switching switch K1 master
Point a from normally opened contact c switch to normally-closed contact b adhesives, from external ac power source AC to contactor coil KM power.
Wherein, the utility model reads 8421 yards of toggle switch K2 by controller W, and is scaled the time, during by this
Between be used as the default anti-shake electric time, toggle switch K2 has two-position switch, and its time setting range is the 0-9.9 seconds, and dial-up is opened
K2 is closed to be connected with controller W.
Toggle switch K2 is arranged to 00 and represents anti-shake electric exit instruction.
Using the anti-shake electric installation of the utility model, contactor coil KM is by external ac power source AC when normal, at device
In stand-by state, within the anti-shake electric time, contactor coil KM is switched to standby direct current supply module DC by device, in anti-shake electricity
Time arrive or anti-shake electric time inside and outside voltage recover when, contactor coil KM is switched to external ac power source AC by device again.
The rolling electricity of general factory seldom occurs within the several seconds, and the utility model device only works within a very short time, therefore makes
Greatly prolonged with the life-span.If other device internal fault damage, contactor will automatically switch to outside friendship on hardware mode
Power supply AC power supplies are flowed, and anti-shake Electricity Functional automatically exits from hardware mode.Therefore plant failure is not influenceing contactor just
Often operation, realizes the backup type in physical significance.
The adaptive contactor capacity of the utility model, for the contactor of different capabilities, without more arrange parameter or change
Wiring, simplify type selecting, reduce Parts Inventory, the time for reducing installation and debugging and difficulty, reduce product maintenance workload.
But those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally
Utility model, and being not used as to restriction of the present utility model, if in spirit of the present utility model, to
Change, the modification of the upper embodiment will all fall in Claims scope of the present utility model.
