The utility model is when more and capacity is big when the platform number of motor, and self-starting can avoid a self-starting to influence that electrical network produced in batches.For example: two motors is arranged, start one at every turn, start at twice, the utlity model has the advantage that used components and parts are few, circuit is simple, failure rate is low.
Description of drawings
Fig. 1 is the motor of the present utility model self-start circuit schematic diagram in batches of sending a telegram in reply.
Embodiment
As shown in Figure 1, the utility model is sent a telegram in reply in batches by the motor on the two-phase circuit that is connected in the three-phase line, and self-start circuit constitutes, what be respectively arranged with the first A.C. contactor KM1 and the second A.C. contactor KM2 on the triple line of the first motor M1 and the second motor M2 often opens main contacts, and motor sends a telegram in reply in batches that self-start circuit comprises selector switch SA, the coil of the first A.C. contactor KM1 that is connected with selector switch SA, the auxiliary normally opened contact of the first A.C. contactor KM1 that is in parallel with the coil of the first A.C. contactor KM1 and the series circuit of motor relay indicating light HL1, the coil of the time relay KT1 that is in parallel with the first motor relay indicating light HL1 and the normally-closed contact series circuit of auxiliary relay KA1, the series circuit of the normally opened contact of the time relay KT1 that is in parallel with the coil of the first A.C. contactor KM1 and the coil of the second A.C. contactor KM2, the second A.C. contactor KM2 normally opened contact that is in parallel with the normally opened contact of time relay KT1, the coil series circuit of often opening main contacts and auxiliary relay KA1 of the second A.C. contactor KM2 that is in parallel with the coil of the first A.C. contactor KM1, the second motor relay indicating light HL2 that is in parallel with the coil of auxiliary relay KA1.
In motor is sent a telegram in reply in batches self-start circuit; with be connected with the first fuse RD1 and the second fuse RD2 on the circuit that triple line is connected; between the first fuse RD1 and the second fuse RD2, be connected with indicator light HL, also be connected with control motor M1 and the first motor overload protection relay FR1 of M2 and the normally-closed contact of the second motor overload protection relay FR2 simultaneously with on the circuit that triple line is connected.
The three-phase line of this device is provided with battery main switch QS, fast acting fuse FU1 and the first motor overload protection relay FR1 and the second motor overload protection relay FR2.
When more and capacity was big when the platform number of motor, self-starting can avoid a self-starting to influence that electrical network produced in batches.For example: two motors is arranged, start one at every turn, start at twice.
During normal the startup, the QS that closes, HL is bright, the SA that closes then, the KM1 coil gets electric, and motor M1 starts, and HL1 is bright for its relay indicating light, and time relay KT1 coil gets.The KT1 delay time arrives, and the KM2 coil gets electric, and motor M2 starts, and the bright and KA1 coil of its relay indicating light HL2 gets.The KA1 normally-closed contact disconnects, and makes the KT1 outage, and the KT1 normally opened contact disconnects, but because the contact self-locking of KM2, KM2 still has.When motor ran well, time relay KT1 must not electricity, help like this electrical energy saving and time expand relay useful life.If have many motor requirements to divide several self-startings, utilize similar control method can realize equally.When needing to shut down, disconnect SA, contactor KM1, KM2 coil losing electricity, motor M1, M2 shut down.
If the power failure phenomenon occurs during the motor operation, HL goes out, KM1, KM2 coil losing electricity, and the two motors stall, its relay indicating light HL1, HL2 go out.When restoring electricity, because QS, SA remain closed, self-starting is once in batches again again for motor.
