Embodiment:
The present invention is described in detail below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4.
A kind of motor timing automatic replaces rotating double interlocking control circuit block diagram as shown in Figure 1, motor forward/backward rotation control main loop circuit figure as shown in Figure 2, on-delay time relay KT1 self is inner one group often opens, the normally-closed contact connection layout as shown in Figure 3, motor forward/backward rotation control loop circuit diagram is as shown in Figure 4.In Fig. 1, timing control unit is made of the on-delay time relay, the motor forward/backward rotation control loop is realized with the routine techniques means, it is controlled switching on and off of different contactor main contactss and realizes that control Motor Control major loop prograde circuit or circuit for reversing are switched on or switched off, the double interlocking circuit by a group of the on-delay time relay self inside often open, normally-closed contact is connected in series with the auxiliary normally-closed contact of contactor KM1 and KM2 respectively and forms.Fig. 2 is conventional motor forward/backward rotation control main loop circuit.Fig. 3 be the present invention require on-delay time relay KT1 self inner one group have often open, the structure of normally-closed contact, wherein side a and b maintains static, the C end is removable for common port, C holds or shift to the A end makes A-C be communicated with (this moment, B-C disconnected), C holds or shift to the B end makes B-C be communicated with (this moment, A-C disconnected), the situation that A-C and B-C are communicated with simultaneously will not occur, double interlocking circuit of the presently claimed invention by one group shown in Figure 3 often have open, the structure of normally-closed contact is connected in series with the auxiliary normally-closed contact of contactor KM1 and KM2 and consists of.Fig. 4 is motor forward/backward rotation control loop circuit diagram, and the double interlocking circuit just is included among Fig. 4.A kind of motor timing automatic replaces rotating double interlocking control circuit and is made of Fig. 2 and Fig. 4.
In Fig. 4, SB1 and SB2 are push-button switches, and KM1 and KM2 are contactor coils, KM3 is relay coil, and KT1 and KT2 are the on-delay time relay coils, and FU1 is fuse, FR is the control contact of thermal relay among Fig. 2, and physical circuit connects as follows: see that summary of the invention is described.
The specific works mode is as follows:
Such as Fig. 2, shown in Figure 4, suppose KM1(KM2) motor forward (counter-rotating) during the main contacts adhesive of contactor, before actuating motor rotating operation, set first the delay time of time relay KT1 and KT2.Slightly stop a moment after pressing the button SB2, then unclamp the SB2 button, two normally opened contacts of the KM3-1 of KM3 relay, KM3-2 close, the KM3 relay coil keeps energising, and contactor KM1 coil electricity, motor begin the forward power supply, KT1 coil electricity and KT1 begin regularly, two normally-closed contacts of KM1-1 and KM1-2 disconnect KT2 coil blackout, KM2 coil blackout; When the KT1 timing then, the KT1 normally-closed contact disconnects first, then the KT1 normally opened contact closes, contactor KM1 coil cuts off the power supply first, and then KM1-1 and two normally-closed contacts of KM1-2 close, then the KM2 coil electricity, then the KM2-1 normally-closed contact disconnects, motor stops to begin the counter-rotating power supply after the forward power supply, and KT2 coil electricity, KT2 begin regularly; When the KT2 timing then, the KT2 normally-closed contact disconnects, the KT1 coil blackout also makes KT1 reset to initial condition, the KT1 normally opened contact disconnects first, then the KT1 normally-closed contact closes, the KM2 coil cuts off the power supply first, the KM2-1 normally-closed contact closes, KM1 coil electricity then, and KM1-1 and KM1-2 normally-closed contact disconnect, motor stops to begin the forward power supply after the counter-rotating power supply, the KT2 coil blackout also makes KT2 reset to initial condition, and the KT2 normally-closed contact closes, and the KT1 coil is switched on again, KT1 begins again regularly to repeat the process of front; Motor is constantly carrying out rotating and reverse operation according to KT1 and KT2 timing.When the needs motor is out of service, press the button and slightly stop behind the SB1 a moment, then unclamp the SB1 button and get final product.
In Fig. 4, the KT1 normally-closed contact is serially connected in the KM1 path of winding, the KT1 normally opened contact is serially connected in the KM2 path of winding, because closed simultaneously phenomenon all can not occur in the normally-closed contact of KT1 and normally opened contact, see Fig. 3, so the simultaneously phenomenon of energising just can not occur in KM1 coil and KM2 coil, thereby KM1-1 and two normally-closed contacts of KM2-1 just can not be closed simultaneously, therefore, the phenomenon of Motor Control major loop short circuit just can not occur, so, utilize often opening of KT1, two normally-closed contacts of normally-closed contact and KM1-1 and KM2-1 just can be realized the double interlocking effect to KM1 coil and KM2 coil electricity.
A kind of motor timing automatic of the present invention replaces rotating double interlocking control circuit, except can be used for motor forward/backward rotation timing automatic conversion operation control, also can be used for the unidirectional operation control of motor through simple process.
