The reversible tumbler of motor of the adjustable duration of condition setting motor rotation time.
It is of the invention to be for the technical solution adopted for solving the technical problem:
A kind of reversible tumbler of motor of adjustable duration, including motor and the time relay, when the time relay includes
Between relay T1 and the time relay T2, the time relay T1 and time relay T2 be arranged on 380V in parallel
In circuit, the time relay T1 and auxiliary reclay Z1 normally opened contact NO is connected in series, the time relay T2 with
Auxiliary reclay Z1 normally-closed contact NC is connected in series, and two three-phase solid relays are provided with the 380V circuits, respectively
For three-phase solid relay SSR1 and three-phase solid relay SSR2, the three-phase solid relay SSR1 and three-phase solid relay
Device SSR2 input and output are both connected to together, and the output line sequence of the three-phase solid relay SSR1 is A, B, C, the three-phase
Solid-state relay SSR2 output line sequence is C, B, A, three-phase solid relay SSR1 one end passage time relay T1's
Normally opened contact S1 is connected with 24V, the normally opened contact S2 of three-phase solid relay SSR2 one end passage time relay T2 with
24V connections, the auxiliary reclay Z1 and auxiliary reclay Z1 normally opened contact NO's and auxiliary reclay Z1 is normally closed
Contact NC connections, the both sides of the auxiliary reclay Z1 are respectively arranged with switch K1 and switch K2.
A, B, C circuit left end meets 380V, and right-hand member is connected on 380V motors, the switch K1 and switch K2
To meet 24V and ground connection respectively, so as to form high level or low level, the switch K1 is controlled by computer, the switch K2 by
Manual control.
The model JSP14 of the time relay, the model TSR-40A of the three-phase solid relay, in described
Between relay model JCZ22/Z.
The present invention positive beneficial effect be:
1st, the present invention can realize live artificial start stop operation and the control of remote computer start stop operation, can also the artificial behaviour in scene
Make and computer operation intersection is controlled, solve the unhandy problem that single control mode is brought, a switch
It is broken or to be repaired, can be operated, do not dallied over one's work using another switch.
2nd, the present invention in the time relay setting, can taking human as progress motor rotation time setting, make motor can
After carrying out operating a period of time according to the random time of setting, antiport is then carried out, the time of setting can be according to existing
Field actual conditions are specifically set, easy to operate.
Brief description of the drawings:
Fig. 1 is the circuit theory diagrams of the reversible tumbler of motor of the adjustable duration of the present invention.
Embodiment:
Below in conjunction with the accompanying drawings 1 and specific embodiment the present invention will be further explained:
Embodiment:A kind of reversible tumbler of motor of adjustable duration, including motor and the time relay, the time relay include
Time relay T1 and time relay T2, time relay T1 and time relay T2 are arranged on 380V electricity in parallel
Lu Zhong, time relay T1 and auxiliary reclay Z1 normally opened contact NO are connected in series, time relay T2 and auxiliary reclay
Z1 normally-closed contact NC is connected in series, and two three-phase solid relays, respectively three-phase solid relay are provided with 380V circuits
Device SSR1 and three-phase solid relay SSR2, three-phase solid relay SSR1 and three-phase solid relay SSR2 input and output are equal
Link together, three-phase solid relay SSR1 output line sequence is A, B, C, and three-phase solid relay SSR2 output line sequence is
C, B, A, three-phase solid relay SSR1 one end passage time relay T1 normally opened contact S1 are connected with 24V, three-phase solid after
Electrical equipment SSR2 one end passage time relay T2 normally opened contact S2 is connected with 24V, auxiliary reclay Z1 and auxiliary reclay Z1
Normally opened contact NO and auxiliary reclay Z1 normally-closed contact NC connections, auxiliary reclay Z1 both sides are respectively arranged with switch
K1 and switch K2.
A, B, C circuit left end meet 380V, and right-hand member is connected on 380V motors, and switch K1 can meet 24V respectively with switch K2
And ground connection, so as to form high level or low level, switch K1 is controlled by computer, and switch K2 is by manual control.
The model JSP14 of the time relay, the model TSR-40A of three-phase solid relay, the type of auxiliary reclay
Number it is JCZ22/Z.
During work, turn on the power, using computer operated switch K1 or utilize live manual control switch K2, opened when two
When electrical potential difference is produced between pass, auxiliary reclay Z1 conductings, and meanwhile auxiliary reclay Z1 normally-closed contact NC closures, time relay
Device T2 energized actions, and time relay T2 normally opened contact S2 is also closed, three-phase solid relay SSR2 closures, motor is just
Turn;After motor, which rotates forward the time, reaches the actuation time of time relay T2 settings, auxiliary reclay Z1 normally opened contact NO is closed
Close, time relay T1 energized actions, and time relay T1 normally opened contact S1 is also closed, three-phase solid relay SSR1 is closed
Close, while auxiliary reclay Z1 normally-closed contact NC disconnects, time relay T2 normally opened contact S2 disconnects, three-phase solid relay
Device SSR2 also disconnects, motor reversal.
It is described above, only it is the preferred embodiments of the present invention, any formal limitation is not made to the present invention, it is all
It is any simple modification, equivalent change and modification made according to the technical spirit of the present invention to above example, still falls within
In the protection domain of technical solution of the present invention.
