Technical field
The utility model relates to a kind of motor control assembly, relates in particular to a kind of clockwise and anticlockwise motor control device that is used to prevent phase fault.
Background technology
When motor rotating changing-over, normal big or misoperation because of motor capacity, the contact can produce very serious starting the arc phenomenon; If fully during arc extinguishing, the A.C. contactor of counter-rotating is closed, will cause phase fault as yet; Cause burning out power consumption equipment, and have many potential safety hazards.
Summary of the invention
The purpose of the utility model provides a kind of clockwise and anticlockwise motor control device that is used to prevent phase fault with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises relay, first contactor, second contactor, just changes the moving disconnecting contact of push-button switch, invert button switch, stop button switch and thermal relay; Saidly just changeing push-button switch and said invert button switch is the compound button switch; First normally closed switch of said relay and two ends after the said normally opened contact that is just changeing push-button switch is connected be first shunt circuit after first normally opened contact of said first contactor is parallelly connected; Second normally opened contact of said first contactor be second shunt circuit after first normally opened contact of said second contactor is parallelly connected; Second normally-closed contact of said relay and two ends after the normally opened contact of said invert button switch is connected be the 3rd shunt circuit after second normal open switch of said second contactor is parallelly connected; Said first contactor successively be first series loop after the normally-closed contact of the normally-closed contact of said second relay, said first shunt circuit and said invert button switch is connected; After the other end of said relay and said second shunt circuit are connected in series is second series loop; Said second contactor successively be the 3rd series loop after the normally-closed contact of said first contactor, said the 3rd shunt circuit and the said normally-closed contact that is just changeing push-button switch are connected; Its two ends end was connected with an end of AC power and an end of said stop button switch respectively after said first series loop, said second series loop and said the 3rd series loop were connected in parallel, and the other end of said stop button switch is connected with the other end of said AC power.
Further, also be connected in series with the thermal relay break contact between said AC power and the said stop button switch.
The beneficial effect of the utility model is:
The utility model can effectively prevent the phase fault phenomenon that when motor rotating changing-over, causes, eliminates safe hidden trouble, improves motor useful life, avoids burning out controller, has reduced unnecessary loss.
Description of drawings
Accompanying drawing 1 is the circuit structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing: the utility model comprises relay K, the first contactor KM1, the second contactor KM2, just changes the moving disconnecting contact FR of push-button switch SB3, invert button switch S B2, stop button switch S B1 and thermal relay; Just changeing push-button switch SB3 and invert button switch S B2 is the compound button switch; The first normally closed switch K1 of relay K and two ends after the normally opened contact that just changes push-button switch SB3 is connected be first shunt circuit after the first normally opened contact KM1-2 of the first contactor KM1 is parallelly connected; The second normally opened contact KM1-3 of the first contactor KM1 be second shunt circuit after the first normally opened contact KM2-2 of the second contactor KM2 is parallelly connected; The second normally-closed contact K2 of relay K and two ends after the normally opened contact of invert button switch S B2 is connected be the 3rd shunt circuit after the second normal open switch KM2-3 of the second contactor KM2 is parallelly connected; The first contactor KM1 successively be first series loop after the normally-closed contact of normally-closed contact K2, first shunt circuit and the invert button switch S B2 of second relay is connected; Be second series loop after the other end of relay K and second shunt circuit are connected in series; The second contactor KM2 successively be the 3rd series loop after connecting in normally-closed contact KM1-4, the 3rd shunt circuit of the first contactor KM1 and the normally-closed contact that just changeing push-button switch SB3; First series loop, second series loop and the 3rd series loop its two ends end of back that is connected in parallel is connected with an end of AC power and the end of stop button switch S B1 respectively, and the other end of stop button switch S B1 and thermal relay break contact FR are connected with the other end of AC power after connecting again.
Shown in accompanying drawing: the utility model utilizes interlocking relay to prolong change-over time and prevents phase fault.Press when just changeing push-button switch SB3, the first contactor KM1 gets electric adhesive and self-locking, and the motor forward starts running; Simultaneously; The second normally opened contact KM1-3 of the first contactor KM1 is closed, makes interlocking relay K get electric adhesive and self-locking, and the relay first normally-closed contact K1 and the relay second normally-closed contact K2 that are connected in the first contactor KM1 and the second contactor KM2 circuit break off; It is electric that the second contactor KM2 can not be got, and realizes interlocking.When pressing invert button SB2, at first break off the first contactor KM1 control circuit, the first contactor KM1 release of cutting off the power supply; When its main contacts KM1-1 breaks off; After treating that electric arc extinguishes fully, the interlocking relay K release of cutting off the power supply, at this moment the second normally-closed contact K2 of interlocking relay K is closed; The second contactor KM2 could get electric adhesive and self-locking, and motor could backward rotation.
The sort circuit arc short circuit in the transfer process that can prevent fully to reverse is applicable to the occasion of change-over time less than the quenching time.
